Description

Ventilator {VENTILATOR}

The present invention relates to a ventilator, and more particularly, to a ventilator that mixes and recirculates air introduced into the room from the outside to the room, thereby preventing condensation from occurring inside and outside the equipment, The present invention relates to a ventilation apparatus capable of maximizing efficiency and particularly capable of keeping the room at a positive pressure at all times to prevent contamination from the outside.

In general households and offices, there is installed a cooling and heating device to perform indoor cooling and heating according to the seasonal changes. Such a cooling and heating device includes an air conditioner for cooling and heating the indoor air by cooling and heating the indoor air , And boilers.

Since the indoor air such as a general home and office where the air conditioner and the heating device are installed is maintained in a hermetically closed state in order to improve the cooling and heating efficiency, Odor is generated or foreign matter such as dust becomes floating. Accordingly, the room air is ventilated every predetermined time to remove the odor or dust from the room. It is necessary to ventilate the contaminated room air to the outside while maintaining the room temperature, and to ventilate the fresh outdoor air to the room Device is used.

Generally, when the outside wall is installed in an insulated space in an apartment or a building, condensation may be minimized inside the ventilation unit. However, when the outside wall of the building is installed in an unheated space, Condensation occurs in the inside of the ventilation apparatus due to a condition substantially similar to that of the outdoor space.

That is, when the outdoor air temperature is low as in winter, the temperature of the space where the ventilator is installed is also lowered. If the ventilator is not used for a long time, condensation will occur inside the ventilator.

In order to prevent condensation from occurring in a ventilator, conventionally, an exhaust fan is sucked into the room by sucking in indoor air, or a heater is installed inside the ventilator to remove condensation by heat generated by the heater Respectively.

However, if the exhaust fan is operated for a certain period of time, the indoor pressure becomes negative pressure, so that contaminated and cold outdoor air can be mixed into the room, and condensation can be prevented only in a passage where room air flows to the outside, There is a limit in which condensation can not be prevented. When the condensation is removed by the heat generated by the heater, there is a problem that consumption of electric energy is increased.

As a prior art related to a ventilation device for preventing the occurrence of condensation, Japanese Patent No. 10-1162973 (a heat recovery type ventilation device provided with a dehumidifying function) is provided with an outdoor air inflow passage and an indoor air vent passage And a dehumidifying function is performed by bypassing the indoor air introduced into the discharge passage to the inflow passage side of the outdoor air by opening the damper and recirculating the indoor air to the indoor side.

However, since the damper is provided on the side wall of the ventilator, the volume of the ventilator is increased in order to secure the space for installing the damper, and the flow path through which the indoor air is recirculated is limited, There is a problem in that condensation can not be prevented over the entire area of the condenser.

On the other hand, there is a bypass type ventilator for performing outside air cooling in the conventional ventilator. This is configured such that heat exchange is not performed between exhausted indoor air and outdoor air to be supplied, so that outdoor air is cooled so that outdoor air is directly introduced into the indoor space, thereby reducing indoor temperature to a certain level. When the bypass mode is not used, air stagnates in the bypass passage, causing air pollution as well as dew condensation. As a result, There is a problem that it causes breeding.

On the other hand, Japanese Patent Application No. 10-0577252 discloses an air cleaning and ventilation system having an air cleaning function and a ventilation function. However, since the ventilation system and the air cleaning apparatus are separately constructed, have.

The total enthalpy heat exchanger (50) has a structure in which a flow passage for flowing indoor air and a flow passage for flowing outdoor air are alternately formed and heat exchange is possible between the indoor air and the outdoor air. A filter (not shown) is disposed on one side of the total enthalpy heat exchanger (50) facing the first air supply chamber (30), for filtering out foreign air supplied from the outside air or indoor air recirculated in an air cleaning mode or a dew condensation control mode 51 are provided. The filter 51 may be a pre-filter, a medium filter, a HEPA filter, a deodorization filter, or the like.

Hereinafter, the operation of the heat exchange mode, the bypass mode, the air blindness mode, and the dew condensation control mode of the ventilator 1 according to the embodiment of the present invention will be described with reference to FIGS. 4 to 11. FIG.

4 and 5, in the heat exchange mode, the air filtering damper 12, the exhaust damper 23, and the air supply damper 33 are opened, and the bypass damper 22 and the mixing damper 32 are opened And the exhaust blower 25 and the air supply fan 43 are driven.

The indoor air flows into the first exhaust chamber 10 through the indoor air inlet 11 and then flows into the indoor air outlet 21 via the total enthalpy heat exchanger 50 and the second exhaust chamber 20, To the outdoor side. The outdoor air is introduced into the first air supply room 30 through the outdoor air inlet 31 and then discharged to the room side through the outdoor heat exchanger 50 and the second air supply room 40 through the outdoor air outlet 41 . The indoor air and the outdoor air pass through the total enthalpy heat exchanger (50) to perform heat exchange.

6 and 7, in the bypass mode, the bypass damper 22, the exhaust damper 23, and the air supply damper 33 are opened, and the air cleaning damper 12 and the mixing damper 32 are closed And the exhaust blower 25 and the air supply fan 43 are driven.

Accordingly, in the bypass mode, the indoor air flows into the first exhaust chamber 10 through the indoor air inlet 11 and then flows downward through the first communication hole 10a, The indoor air passing through the bypass passage 70 is flowed upward through the second communication port 20a and flows into the second exhaust chamber 20, And is discharged to the outdoor side through the discharge port (21). The outdoor air is introduced into the first air supply room 30 through the outdoor air inlet 31 and then discharged to the room side through the outdoor heat exchanger 50 and the second air supply room 40 through the outdoor air outlet 41 .

Therefore, in the bypass mode, heat exchange is not performed between the exhausted indoor air and the outdoor air to be supplied, and the outdoor air is supplied to the indoor side without changing the temperature.

6 (a), the dashed arrows indicate the flow paths of the room air passing through the bypass passage 70, and the relatively thick lines in FIG. 7 show the flow paths of the room air and the room air, This is the same in the following drawings.

8 and 9, in the air cleaning mode, the mixing damper 32 is opened and the air cleaning damper 12, the bypass damper 22, the exhaust damper 23, and the air supply damper 33 are closed And the air supply fan 43 is driven.

Therefore, in the recirculation mode, the room air is introduced into the first exhaust chamber 10 through the room air inlet 11, and then the flow direction is switched downward through the first communication hole 10a, The indoor air passed through the bypass passage 70 is flowed upward through the third communication hole 30a and flows into the first air supply chamber 30, 50 and the second class air chamber 40 and is discharged to the room side.

In this air clean mode, the foreign substances contained in the recirculated indoor air are filtered by the filter 51, so that the indoor air can be cleaned and the indoor air can be circulated through the bypass passage 70 It is possible to prevent the occurrence of condensation in the entire area of the ventilator 1 and to prevent the occurrence of condensation in the bypass passage 70 It is possible to prevent the propagation of bacteria due to the air pollution which may be caused when the air flow stagnates inside the inside of the indoor space.

10 and 11, in the dew condensation control mode, the air cleaning damper 12, the exhaust damper 23, the mixing damper 32 and the air supply damper 33 are opened and the bypass damper 22 is closed And the exhaust blower 25 and the air supply fan 43 are driven.

Therefore, in the condensation control mode, a part of the room air introduced into the first exhaust chamber 10 through the room air inlet 11 is changed in flow direction downward through the first communication hole 10a, The indoor air passing through the bypass passage 70 is flowed upward through the third communication port 30a to flow into the first air supply chamber 30, Is mixed with the outdoor air introduced into the air supply chamber 30 and is exhausted to the room side through the total enthalpy heat exchanger 50 and the second air supply room 40 and flows into the first exhaust chamber 10 through the room air inlet 11 The rest of the introduced indoor air passes through the total enthalpy heat exchanger (50) and the second exhaust chamber (20) and is exhausted to the outside. In the condensation control mode, all of the room air introduced into the first exhaust chamber 10 through the room air inlet 11 flows through the first communication hole 10a, the bypass passage 70 and the third communication hole 30a to flow into the first air supply chamber 30. In this case, the air cleaning damper 12 can be controlled to be closed.

In the condensation control mode, it is possible to introduce fresh outdoor air to the indoor side together with the recirculation of the indoor air, thereby satisfying the necessary ventilation amount of the indoor resident room, thereby creating a pleasant indoor environment and preventing generation of sound pressure in the indoor space So that it is possible to prevent the inflow of the contaminated and cold outdoor air which may be caused when the sound pressure is generated. Also, in the condensation control mode, as in the case of the above-described air cleaning mode, room air flows into the bypass passage 70 formed over the entire lower portion of the ventilator 1, And it is possible to prevent the propagation of bacteria caused by the air pollution which may be caused when the air flow is stagnated inside the bypass passage 70.

On the other hand, the control unit 90 controls the dew point of the indoor air calculated by the temperature and humidity values measured by the first temperature sensor 13 and the second humidity sensor 14, When the temperature measured by the second temperature sensor 42 is lower than the dew point of the room-side air, the mixing damper 32 is opened, and when the temperature measured by the second temperature sensor 42 is lower than the dew point of the indoor air, The number of revolutions of the condenser 43 is increased so as to prevent condensation.

When the humidity of the indoor air measured by the second humidity sensor 24 exceeds the set humidity value (for example, relative humidity 80 to 90%), the controller 90 controls the mixing damper 32 Is opened and the number of revolutions of the air supply fan (43) is increased, thereby preventing the occurrence of condensation.

The ventilator 1 according to another embodiment of the present invention shown in FIG. 12 to FIG. 14 includes the first temperature sensor 13 and the first humidity sensor 14, which are the configurations of the above- (15), and other configurations are the same as those of the above-described embodiment.

In the present embodiment, the controller 90 compares the temperature of the indoor air measured by the dew point temperature sensor 15 with the temperature of the outdoor air supplied to the room measured by the second temperature sensor 42, When the temperature measured by the temperature sensor 42 is lower than the dew point of the indoor air measured by the dew point temperature sensor 15, the mixing damper 32 is opened and the rotation speed of the air supply fan 43 So that the occurrence of condensation is prevented.

The air blowing capacity of the air supply blower 43 is set such that the room air flowing into the first exhaust chamber 10 in the dew condensation control mode corresponds to the set flow rate bypassed to the first air supply chamber 30 Is set to be larger than the blowing capacity of the exhaust blower (25).

For example, when the flow rate of the air exhausted through the outdoor air outlet 21 is 100, the flow rate of the air supplied through the outdoor air inlet 31 is 100, the flow rate of the room air mixed into the outdoor air to be supplied is 50 The indoor air of the flow rate 150 flows into the room air inlet 11 and the flow rate 100 of the room air of the flow rate 150 flows through the total enthalpy heat exchanger 50 and the exhaust blower 25 of the second exhaust chamber 20 The flow rate 50 of the room air having a flow rate of 150 flows into the first feed chamber 30 via the bypass passage 70 and then flows into the first feed chamber 30 through the outdoor air inlet 31, The air having the flow rate 150 mixed in the first air supply chamber 30 is mixed with the outdoor air having the flow rate of 100 introduced into the indoor heat exchanger 50 through the air supply fan 43 of the second air supply chamber 40 .

In this case, the exhaust blower 25 is set to a capacity capable of blowing air having a flow rate of 100, and the air supply fan 43 is set to a capacity capable of blowing air having a flow rate of 150.

According to the ventilator 1 of the present invention configured as described above, it is possible to use both the bypass mode and the air purifying mode and the condensation control mode as a flow path for passage of room air in the lower or upper part of the ventilator 1 And by controlling the ventilator 1 to operate in accordance with the condition for each mode, it is possible to effectively prevent the occurrence of condensation in the entire area of the ventilator and to reduce the required ventilation amount of the occupant in the room There is an advantage that energy efficiency can be maximized while satisfying sufficiently.
