Description

  The present invention relates to a central air conditioning system, and in particular, a single duct air conditioning system that sends hot air and cold air through a single duct, a building to which the air conditioning system is applied, and an air conditioner used for air conditioning of the building. Regarding the method.

  The air conditioning system is roughly divided into two types: a central system (central management system) and an individual system. Residential comfort is largely dependent on room temperature control, and there are many individual systems that use wall-mounted air conditioners installed in each room. By installing a wall-mounted air conditioner in each room, there is an advantage that the temperature can be set individually. However, since the number of installed units increases, initial and running costs (such as utility costs) are incurred. is there. Panel heaters that can reduce utility costs to some extent can provide comfort in winter, but additional cooling equipment is required in summer, which incurs additional construction costs.

  In order to solve these problems, there is a need for a central-type air conditioning system that realizes cooling and heating of the entire building with one air conditioner serving as a heat source and a cooling heat source (refrigerator). In addition, due to the recent increase in heat insulation and airtightness of residential buildings, legal obligations have been made for the installation of ventilation equipment for new houses in order to regulate volatile hazardous chemical substances released from building materials and furniture. It is also essential to install a ventilation system.

  For this reason, the temperature of the air taken from the room through the backflow prevention damper is adjusted by the package air conditioner, and the fresh air that has been taken in from the heat exchange ventilator and heat-exchanged is mixed with the air from the packaged air conditioner in the mixing chamber and supplied to each room An invention of a central air conditioning system (central type first type heat exchange type ventilation method) is described (see Patent Document 1). In the invention described in Patent Document 1, since the entire building has one packaged air conditioner, initial costs such as construction costs for installation can be suppressed.

  In the invention described in Patent Document 1, a mixing chamber is provided at the rear stage (outlet side) of the packaged air conditioner. When a packaged air conditioner is not used, the air from the heat exchange ventilator is ventilated in a mixing chamber provided at a later stage as a separate device from the packaged air conditioner, but is not ventilated inside the packaged air conditioner. . If there is a non-ventilated time zone inside the packaged air conditioner due to nighttime or seasonal circumstances, there is an increased risk of mold, microorganisms, corrosion, etc. occurring inside the packaged air conditioner due to condensation. Mold inside the packaged air conditioner is a serious health problem, but cleaning the packaged air conditioner is not easy. That is, in the conventional central air conditioning system, costs such as cleaning the inside of the packaged air conditioner and time waste occur.

  As described in paragraphs [0050] to [0051] of Patent Document 1, in the invention described in Patent Document 1, the air to the mixing chamber is sent to the chamber side of each fan of the indoor unit of the packaged air conditioner and the heat exchange ventilation fan. In a state where the static pressure of each fan of the packaged air conditioner and the heat exchange ventilation fan is substantially equal to the static pressure in the chamber. The amount of air passing through the chamber must be secured. Moreover, in the invention described in Patent Document 1, a constant air volume is required to open the backflow prevention damper. In the invention described in Patent Document 1, since all the air supplied to the packaged air conditioner is obtained through a backflow prevention damper, the electricity cost is increased when the necessary air volume of the packaged air conditioner is continuously secured. According to the experiment of the present inventor, in the invention described in Patent Document 1, it was found that the backflow prevention damper sometimes malfunctions from the relationship of the air volume.

(Mode switching)
The outline of the air flow mode in air conditioning management using the air conditioning system according to the embodiment of the present invention will be described below with reference to FIG. In the air conditioning system according to the embodiment of the present invention, in order to prevent the occurrence of mold or the like in the central duct or the like, the outdoor air processing unit 11 starts from the outside air processing unit 11 in the season when the air conditioning or the like is not required. In the operation mode of constantly maintaining the ventilation of the heat exchanged clean air into the air conditioner 13 and the duct, electric energy is effectively used, and at the same time, the air conditioner 13 and the inside of the duct are cleanly managed. For this reason, with respect to the air supply, first, the air of the outside air processing unit 11 is taken into the outside air duct 31 by the flow of the arrow A from the outdoor air inlet 21. The taken-in air is appropriately subjected to heat exchange and air purification in the outside air processing unit 11, passes through the connection duct 32, and is taken into the air conditioner 13.

  When the entire building is air-cleaned using only the outside air processing unit 11 without operating the air conditioner 13 shown in FIG. The circuit is in an off state, and as shown in FIG. 1, the blades 45 of the electric damper are in a fully closed state that blocks the flow of air inside the return air duct 37. In this case, air is not sucked from the indoor suction port 29, and no air flows into the air conditioner 13 through the return air duct 37. The air that has passed through the connection duct 32 passes through the inside of the air conditioner 13 and flows into the first air supply duct 33a and the second air supply duct 33b. The purified air that has flowed in is supplied from the first indoor air supply port 22a and the second indoor air supply port 22b as the air in the direction of arrows C and D in FIG.

  On the other hand, when the air conditioning management of the entire building is performed using both the air conditioner 13 and the outside air processing unit 11 shown in FIG. 1 in summer and winter seasons when air conditioning is required, the power supply circuit of the control unit 15 of the air conditioner 13 is used. Is in an on state, and the blade 45 is not in the closed state shown in FIG. 1 and is not shown in the figure, but is in a fully open state in which air is passed through the return air duct 37. When the fan of the air conditioner 13 is activated, air is taken into the return air duct 37 from the indoor suction port 29 in the flow of the arrow B. The taken-in air and the air sent from the outside air processing unit 11 are air-conditioned to an appropriate temperature and humidity by the air conditioner 13, flow into the first air supply duct 33a and the second air supply duct 33b, and the first room From the air supply port 22a and the second indoor air supply port 22b, air is supplied (blowed) individually to each room as the air in the direction of arrows C and D in FIG.

  As for exhaust, in FIG. 1, air flows into the exhaust suction duct 34 from the exhaust sampling port 23 in the flow of the arrow E, enters the outside air processing unit 11, and is subjected to appropriate heat exchange. As shown in FIG. 1, the air flows in the direction of arrow F and is discharged from the outdoor exhaust port 24.

  FIG. 2A shows the rotational position of the blade 45 in the fully closed state, and FIG. 2B shows the rotational position of the blade 45 in the fully opened state. As shown in FIGS. 2A and 2B, the blade 45 is installed in a cavity inside the return air duct 37 and is rotatable about the damper shaft 44. The blade 45 may have any shape as long as it can close the cavity inside the return air duct 37 and block the air flowing in the direction of arrow A when it is in the fully closed state as shown in FIG. Well, it is not limited to the single-wing type butterfly valve shown in FIGS. 2 (a) and 2 (b). When the blade 45 is rotated 90 degrees in the directions of B and C in FIG. 2A, the blade 45 is fully opened in FIG. In FIG. 2B, the blade 45 does not block the cavity inside the return air duct 37 and can pass through the air in the directions of arrows A and B without blocking. Further, when the blade 45 rotates 90 degrees around the damper shaft 44 from the fully open rotation position as shown in FIG. 2B, the blade 45 returns to the fully closed rotation position as shown in FIG. Cut off the flow. To return to the fully closed rotation position, rotation using an elastic force such as a spring return can be used. 2A and 2B, the two-position control check valve type in which the blades 45 rotate 90 degrees has been described. However, for adjusting the air volume that rotates to an arbitrary angle by proportional control and allows an arbitrary air volume to pass. It may be a feather. The damper shaft 44 may be positioned at the center of the blade 45 as shown in FIGS. 2A and 2B or may be positioned at the end.

  As described above, according to the air conditioning system according to the embodiment, the mode in which only the clean air heat-exchanged from the outside air processing unit 11 is ventilated into the duct in a season or the like where the air conditioner 13 or the like does not require air conditioning, In summer and winter seasons when air conditioning is required, the air conditioning unit adjusts the temperature etc. for the mixed air of clean air and air that has flowed through the return air duct, and the adjusted air flows through the air supply duct The mode switching operation can be performed in conjunction with the operation of the blades 45 of the electric damper by turning on / off the power supply circuit of the control unit 15 of the air conditioner 13.

(About upper and lower connecting ducts)
As shown in FIG. 1, the air conditioning system according to the embodiment of the present invention can further include an upper and lower connection duct 39 that connects an upper layer and a lower layer of a building to which the air conditioning system is applied. Of the “upper and lower layers of the building”, the “upper layer” is the upper layer in the building in the vertical direction, and the “lower layer” is the lower layer in the building in the vertical direction. . For example, it means the second floor of the building and the first floor located vertically below (see FIGS. 6 and 7). In FIG. 1, the upper and lower connection ducts 39 extending linearly in the vertical direction are shown. However, the upper and lower connection ducts 39 may be bent halfway in a crank-like topology. A first intermediate fan (intermediate fan) 43a and a second intermediate fan 43b are provided in the cavity inside the upper and lower connecting duct 39, and the first intermediate fan 43a and the second intermediate fan 43b are as shown in FIG. Are respectively held by the intermediate fan support shaft 42a and the intermediate fan rotation shaft 42b. In other words, the interlocking mechanism 30 of the air conditioning system according to the embodiment further includes the fan controller 19 electrically connected to the operation circuit unit 41 by the fourth wiring 49, and the fan controller 19, the first intermediate fan 43 a, Two intermediate fans 43b are electrically connected.

  As shown in FIG. 3A, the first intermediate fan 43a and the second intermediate fan 43b are counter rotation fans that rotate in the opposite directions. When the first intermediate fan 43a rotates in the A direction, the second intermediate fan 43b rotates in the B direction opposite to the A direction. When the first intermediate fan 43a rotates in the direction opposite to the A direction, the second intermediate fan 43b rotates in the direction opposite to the B direction. When the first intermediate fan 43a and the second intermediate fan 43b rotate in a certain direction, air flows in a certain direction through the cavity inside the upper and lower connection duct 39 that connects the upper and lower layers of the building. When the rotation directions of the first intermediate fan 43a and the second intermediate fan 43b are switched, the air flowing through the cavity inside the upper and lower connection duct 39 flows in the opposite direction.

  In FIG. 3 (b), by the continuous rotation of the first intermediate fan 43a and the second intermediate fan 43b in a certain direction, the air flowing in the direction indicated by the arrow A is taken into the upper and lower connection duct 39 from the first supply / exhaust port 25a. 2 It discharges | emits as the air of the flow of the arrow B from the supply / discharge port 25b. When the rotation in the direction opposite to the rotation of the first intermediate fan 43a and the second intermediate fan 43b in FIG. 3 (b) is performed, the flow of the arrow B from the second supply / exhaust port 25b as shown in FIG. 3 (c). Air is taken into the upper and lower connecting ducts 39 and discharged from the first supply / exhaust port 25a as air flowing in the direction of arrow A.

  In general, warm air tends to accumulate upward and cold air tends to accumulate downward. As shown in FIGS. 3B and 3C, the first supply / exhaust port 25a is installed at a higher position (upper layer) than the second supply / exhaust port 25b, so that it is relatively warm in FIG. 3B. Air can be sent downward (lower layer), and in FIG. 3C, relatively cool air can be sent upward (upper layer).

  In FIG. 1 and FIGS. 3A, 3B, 3C, etc., the first intermediate fan 43a and the second intermediate fan 43b are used in the upper and lower connecting duct 39. The number of intermediate fans may be one, or three or more.

  In FIG. 1, the operations of the first intermediate fan 43 a and the second intermediate fan 43 b provided in the upper and lower connection duct 39 are interlocked with the operation of the air conditioner 13 via the operation circuit unit 41. When the air conditioner 13 is turned on by operating the buttons of the control unit 15, an electrical signal is transmitted to the operation circuit unit 41, and an electrical signal is transmitted from the operation circuit unit 41 to the fan controller 19. Then, the rotation of the first intermediate fan 43a and the second intermediate fan 43b starts. Conversely, when the power supply circuit of the control unit 15 of the air conditioner 13 is turned off, a signal is electrically transmitted to the operation circuit unit 41, and a signal is electrically transmitted from the operation circuit unit 41 to the fan controller 19, The rotation of the first intermediate fan 43a and the second intermediate fan 43b is stopped. That is, in FIG. 1, the on / off of the power supply circuit of the control unit 15 of the air conditioner 13 is interlocked with the on / off of the rotation of the first intermediate fan 43a and the second intermediate fan 43b. The interlocking mechanism 30 in FIG. 1 may be provided with a mechanism in which the rotation directions of the first intermediate fan 43a and the second intermediate fan 43b are automatically switched depending on conditions such as the season and room temperature.

As shown in FIG. 1 and FIG. 3A, even when the first intermediate fan 43a and the second intermediate fan 43b are not rotating, there is a space between the propeller structures that are the flow paths inside the upper and lower connecting ducts 39. Air can freely pass through.

(Electric circuit of interlocking mechanism)
FIGS. 4A and 4B show a first interlocking operation circuit (interlocking operation circuit) 40 included in the operation circuit unit 41 in FIG. 1 and a damper driving unit 17 electrically connected to the first interlocking operation circuit 40. It is a typical block diagram explaining the circuit part of. The constant voltage source 51 is a power source for the first interlock operation circuit 40, and outputs a voltage such as DC 24V. The interlock switch 53 is a switch that is directly or indirectly electrically connected to the power supply circuit of the control unit 15 of the air conditioner 13, and is a power circuit of the control unit 15 of the air conditioner 13, for example, an operation panel of the control unit 15. Interlocks with the on and off states of the circuit connected to the switch. The first coil 55 that is continuous with the interlocking switch 53 on the circuit forms a first switch together with a first normally closed relay contact 61. When the current is not flowing through the first coil 55, the first normally closed relay contact 61 is closed, and when the current is flowing through the first coil 55, the first normally closed relay contact 61 is opened. The first normally closed relay contact 61 is a b contact (break contact), and is always closed when no current flows through the first coil 55. The properties of the second coil 57 and the second normally closed relay contact 63 are the same as those of the first coil 55 and the first normally closed relay contact 61, respectively, and the second coil 57 and the second normally closed relay contact 63 are the second. Make a switch. For the first switch and the second switch, general “electromagnetic relays” and “electromagnetic relays” can be used. However, these are only examples, and the contacts are physically moved by an electromagnet, and the relays that open and close the contacts are insulated. A semiconductor switch such as a gate bipolar transistor (IGBT) may be used. When the semiconductor switch is used for the first normally closed relay contact 61 and the second normally closed relay contact 63, a current sensor or the like may be used instead of the first coil 55 and the second coil 57.

  As shown to Fig.4 (a), when the power supply circuit of the control part 15 of the air conditioner 13 is an OFF state, the interlocking switch 53 is the open state (open). Therefore, no current flows through the first coil 55, and the first normally closed relay contact 61 is in a closed state. Since the first normally closed relay contact 61 is closed, a current flows through the second coil 57, and the second normally closed relay contact 63 is open. Since the second normally closed relay contact 63 is open, no current flows through the third terminal block 75 of the damper drive unit 17. A current flows through a path from the first terminal block 71 to the second terminal block 73 of the damper driving unit 17.

  As shown in FIG. 4B, when the power supply circuit of the control unit 15 of the air conditioner 13 is turned on from the off state, the interlock switch 53 is closed. Therefore, a current flows through the first coil 55 and the first normally closed relay contact 61 is opened. Since the first normally closed relay contact 61 is opened, no current flows through the second coil 57, and the second normally closed relay contact 63 is closed. Since the second normally closed relay contact 63 is closed, a current flows through the third terminal block 75 of the damper driving unit 17. For example, when a DC 24 V current flows through the third terminal block 75, the rotation of the electric motor such as the brushless DC motor of the damper driving unit 17 is driven, and the blade 45 in FIG. 1 is rotated. That is, the blade 45 rotates from the fully closed rotation position of FIG. 2A to the fully open rotation position of FIG. 2B. For example, in the case of a DC motor, when a positive / negative voltage having the same cycle is continuously applied to the DC motor from the damper driving unit 17, the blade 45 is stopped. Further, when the rotational position feedback of the blade 45 is performed by the driving unit 17, a holding force is generated even when the blade 45 is stopped, and the servo lock state is established. The position control of the DC motor is a control for stopping the DC motor by inputting a position command to the stopped DC motor and moving it to a target position. Further, if a torque limiter circuit is built in the damper drive unit 17, it is possible to prevent an excessive current against an overload of an electric motor such as a DC motor.

  In the state of FIG. 4B, when the power circuit of the control unit 15 of the air conditioner 13 is turned off from the on state, the power circuit of the control unit 15 is turned on from the off state. The rotational movement (return) in the opposite direction is performed, and the state returns to the state of FIG. That is, as shown in FIG. 4A, when the power circuit of the control unit 15 of the air conditioner 13 shown in FIG. Therefore, the current of the first coil 55 is interrupted, and the first normally closed relay contact 61 is closed. Since the first normally closed relay contact 61 is closed, a current flows through the second coil 57 and the second normally closed relay contact 63 is opened. Since the second normally closed relay contact 63 is opened, no current flows through the third terminal block 75 of the damper drive unit 17. When the current of the third terminal block 75 is cut off, the pressing force of the motor stopped due to the servo lock state or the like is eliminated.

  In the spring return method, the pressure by the elastic body (spring) acts in the direction opposite to the pressing force of the electric motor, and the blade 45 is moved from the fully opened state rotation position in FIG. 2B to the fully closed state in FIG. The blades 45 are pushed back to the rotation position (spring return). In both the case where the power supply circuit of the control unit 15 of the air conditioner 13 shown in FIG. 1 or the like is changed from the off state to the on state, the end of the rotation operation is the damper in FIG. It may be realized by a delay circuit incorporated in the internal circuit of the drive unit 17, or the rotation of the blade 45 shown in FIGS. 2A and 2B is forcibly stopped by a physical stopper at the end of the rotation operation. You may control to do. 4A and 4B, if the first normally closed relay contact 61 and the second normally closed relay contact 63 have the same function as the b contact, another type of contact such as a c contact is used. It doesn't matter.

  5 (a) and 5 (b), a second interlocking operation circuit (interlocking) in which a third coil (intermediate fan relay coil) 59 is further provided in the first interlocking operation circuit 40 in FIGS. 4 (a) and 4 (b). Operation circuit) 50 is shown. The third coil 59 is connected to the interlock switch 53 on the circuit. Although illustration is omitted, when a current flows through the third coil 59, the normally open relay contact for the intermediate fan operates and an electrical signal is transmitted to the fan controller 19, and the first intermediate fan 43a and the second intermediate fan 43b Start rotating motion. Regarding the nature and function of the second interlocking operation circuit 50 corresponding to the first interlocking operation circuit 40 in FIGS. 4A and 4B, the first interlocking operation in FIGS. This is similar to the circuit 40.

  As shown in FIG. 5A, when the power supply circuit of the control unit 15 of the air conditioner 13 is in the OFF state, the interlock switch 53 is open and no current flows through the third coil 59. Since no current flows through the third coil 59, the normally open relay contact for the intermediate fan does not operate, and the first intermediate fan 43a and the second intermediate fan 43b do not rotate and remain stopped.

  As shown in FIG. 5B, when the power supply circuit of the control unit 15 of the air conditioner 13 is turned on from the off state, the interlock switch 53 is closed. Therefore, a current flows through the third coil 59, the normally open relay contact (not shown) for the intermediate fan is turned on, an electrical signal is transmitted to the fan controller 19, and the first intermediate fan 43a and the second intermediate fan 43b. Start rotating operation.

  The normally open relay contact for the intermediate fan is integrated with the third coil 59 of FIGS. 5A and 5B to form a third switch for the intermediate fan. The intermediate fan normally open relay contact is an electric signal generated when the contact is turned on and transmitted to the fan controller 19 to start the rotation operation of the first intermediate fan 43a and the second intermediate fan 43b. For example, the contact a, the contact b, or any other contact may be used.

In the summer and winter seasons when air conditioning is required, the air that has flowed through the return air duct 37 for securing the air volume necessary for the air conditioner 13 that cannot be compensated by the ventilation of the outside air processing unit 11 The air conditioner 13 adjusts the temperature and the like of the mixed air of clean air and clean air, and performs switching operation of the air for passing the adjusted air into the duct, and the blades 45 of the electric damper are controlled by the control unit 15 of the air conditioner 13. It can be implemented by operating in conjunction with the power circuit on / off. In addition, since fresh air derived from the outside air processing unit 11 and room air can be mixed with the air conditioner 13, a sufficient air volume can be secured when the air conditioner 13 is in operation.

  In particular, even when the power supply circuit of the control unit 15 in FIG. 1 is in an off state, the inside of the outside air duct 31, the connection duct 32, the air supply duct 33a, etc. is ventilated throughout the year. Generation of mold and the like can be suppressed, and it is excellent in terms of hygiene and maintenance. Furthermore, since the inside of the air conditioner 13 is also ventilated, generation of mold and the like inside the air conditioner 13 can be suppressed. By operating the outside air processing unit 11 for 24 hours, the ventilation conditions defined by laws and regulations can naturally be satisfied.

  In the air conditioning system and building according to the embodiment, the air supplied from the room can be taken in from the indoor suction port 29 of the return air duct 37, but the damper used for the return air duct 37 is an electric damper. Since it is not necessary to open and close the damper by the force of sucking air supplied to the air conditioner 13, backflow can be reliably prevented. In particular, by using the first interlocking operation circuit 40 shown in FIG. 4 and the second interlocking operation circuit 50 shown in FIG. 5, a mode in which only clean heat exchanged from the outside air processing unit 11 is ventilated into the duct. Then, the air from the outside air processing unit 11 and the air from the return air duct 37 are mixed (mixed) and adjusted by the air conditioner 13, and the mode for switching the air into the duct is switched by a button on the control unit 15 of the air conditioner 13.

And according to the air-conditioning system and building which concern on embodiment of this invention, it is not necessary to apply high load to the fan of the air conditioner 13, and can send air into the air-conditioner 13 more efficiently.

  In particular, by providing the interlocking mechanisms 20 and 30 that link the operation of the electric damper in the return air duct 37 with the operation of the power supply circuit of the control unit 15, in the season when the air conditioner 13 or the like does not require air conditioning, the outside air Only clean air that has undergone heat exchange from the processing unit 11 is ventilated into the duct, and generation of mold, microorganisms, and the like in the duct can be prevented. If the damper in the return air duct 37 is not closed when the power supply circuit of the control unit 15 is turned off, the air sent from the outside air processing unit 11 passes through the inside of the air conditioner 13 and the return air duct 37 and is sucked into the room. It flows backward from the mouth 29. Since the inside of the return air duct 37 is designed on the premise that the air is sucked in the direction of sucking air, if the air flows backward in the direction of discharging air, the dirty air in the air conditioner 13 and the return air duct 37 is discharged into the room as it is. This is inconvenient for residents. Further, if the damper of the return air duct 37 is not opened when the power supply circuit of the control unit 15 is turned on, the air volume assumed from the return air duct 37 cannot be secured, so that the fan of the air conditioner 13 or the outside air processing unit 11 can be used. There is a possibility that the air conditioner 13 and the outside air processing unit 11 may be broken due to excessive load. In either case, the influence of the operation of the power supply circuit of the control unit 15 and the damper of the return air duct 37 is not significant. In the air conditioning system and building according to the embodiment, the interlocking mechanisms 20 and 30 are provided, so that these inconveniences can be avoided.

  Further, since the damper blade 45 provided in the return air duct 37 is electrically driven, the damper blade 45 is inadvertently opened due to a temporary change in atmospheric pressure when the power supply circuit of the control unit 15 is in an off state. Such inconveniences can be avoided. In the interlocking mechanisms 20 and 30 of the power supply circuit of the control unit 15 and the operation of the electric damper of the air conditioning system according to the embodiment of the present invention, the air conditioner 13 is in the dry mode even when the power supply circuit of the control unit 15 is on. Thus, when the temperature and humidity reach a certain level, it is possible to automatically perform applied air conditioning adjustment, such as closing the blade 45, so that it is difficult for residents to manage one by one.

  In the air conditioning system and building according to the embodiment of the present invention, the temperature difference can be made extremely small through each room of the entire building. As shown in FIG. 1, when the air conditioner 13 is a single central system in the entire building, a problem that a room temperature difference occurs in each room or each floor frequently occurs. If there is a difference in room temperature, heat shock is likely to occur and the body is stressed. Especially for elderly people, the room temperature difference is regarded as a major factor causing stroke and myocardial infarction. In order to eliminate the room temperature difference, in addition to the air conditioner 13, air conditioning equipment according to the season and the like is separately required, which is expensive. In the air conditioning system and the building according to the embodiment of the present invention, by installing the intermediate fans 43a and 43b in the upper and lower connecting duct 39, a temperature difference that usually occurs at 3 ° C or more is generated in the entire building. The temperature difference can be reduced to about 1 ° C. In winter, warm air that tends to accumulate upwards is conveyed downward through the upper and lower connecting ducts 39 with the intermediate fans 43a and 43b, so that the feet that are likely to cool can be efficiently warmed. In summer, cold air can be efficiently circulated throughout the entire building by transporting the cold air below through the upper and lower connecting ducts 39 with intermediate fans 43a and 43b.

  Further, the interlocking mechanism 30 of the air conditioning system according to the embodiment of the present invention can also interlock the operations of the intermediate fans 43a and 43b, and the normal air conditioning management can be performed only by operating the power supply circuit of the control unit 15. In addition, it is possible to obtain effects such as efficient air intake into the air conditioner 13 and relaxation of the temperature difference of the entire building.

  The air conditioning system and the building according to the embodiment of the present invention can be configured by only one air conditioner 13 and one outside air processing unit 11 as hardware for air conditioning for cooling and heating. Comfortable air conditioning can be maintained without using heating equipment, so that the initial cost and running cost of the air conditioning system can be kept lower than those of the prior art. After applying the air conditioning system according to the embodiment of the present invention to a building, even if the necessity for extension and renovation occurs, the air conditioning equipment can be simply branched or rearranged in the various ducts of the air conditioning system. Can be arranged. The air conditioning system and the building according to the embodiment of the present invention can be customized according to the individual occupants and can perform air conditioning management at low cost for many years.

  In the air conditioning system and the building according to the embodiment of the present invention, since it is a central type air conditioning system, there is no need to install a separate air conditioning device in each room, so that there is an advantage that the space can be used effectively. . When the air conditioning system according to the embodiment of the present invention is used in a building, when the ventilation by the outside air processing unit 11 and the air conditioning by the air conditioner 13 are divided into separate systems, the air adjusted by the air conditioner 13 is the outside air processing unit. Although inefficiencies such as escaping to the outside due to the exhaust by 11, the problem can be solved.

In the air-conditioning system and building according to the embodiment of the present invention, since efficient energy use is facilitated, it can be an air-conditioning system that is a base of “Net Zero Energy House (ZEH, Zet)”. “Net Zero Energy House” means improving the heat insulation of the outer walls, maintaining a comfortable indoor environment, saving a lot of energy, and introducing renewable energy to reduce energy consumption to less than zero. It is a building that aims to do. In the air conditioning system and the building according to the embodiment of the present invention, a comfortable indoor environment can be maintained for the occupant, and the ventilation by the outside air processing unit 11 and the air conditioning by the air conditioner 13 are integrated. It is a system that is fundamentally in line with the “Net Zero Energy House” orientation, which enables energy saving by the system.
