An exhaust port 7 is connected to the outdoors.

The evaporator 30 is installed inside the suction window 4 to lower the indoor air temperature sucked by the blower fan 6 and then blows it into the blower window 3, and a refrigerant temperature is provided on the rear surface of the evaporator 30. An electric heater (50) is installed to increase the temperature or lower the indoor humidity, and a condenser (21) and a compressor (10) are installed on the rear surface of the main body (2) in which the cooling unit and the non-cooling unit are separated by the partition wall (60). On the other hand, an exhaust fan 8 for discharging the air heated in the condenser 21 to the exhaust port 7 is provided.

In addition, the bottom of the main body 2 is provided with a humidifier 70 with a built-in humidification auxiliary condenser 20, the humidity of the humidifier 70 is blown through the humidifying pipe 71 to the blower fan 72, the evaporator Condensed water according to the indoor air cooling of (30) is allowed to enter the water tank 74 through the exhaust port (73).

The constant temperature air conditioner (1) of the above-described configuration is the same as Utility Model No. 1999-024139, which was previously filed by the present applicant, but in the present invention, the heating auxiliary condenser 40 is integrally formed on the evaporator 30, but the piping of the evaporator 30 is A pipe of the heating auxiliary condenser 40 is installed along the air, and the air heated or cooled in the condenser 21 can be discharged to the exhaust fan 8 or the blower fan 6 through the duct 45, but the duct (45) Inside is installed a blocking plate 46 to control the air flow in accordance with the air-conditioning selection.

As shown in FIGS. 4 to 6, the electric heater 50 of the present invention attaches the heat dissipation fins 52 to the outside of the multi-stage heating rod 51 to facilitate heat dissipation. The heat conductive semiconductive polymer 53 is installed on both sides, and the inside is filled with the heat medium oil 54.

The overall configuration of the present invention, as shown in Figure 2 during cooling the refrigerant compressed in the compressor 10 passes through the solenoid valve 11 through the humidification subcondenser 20 and the condenser 21 after the auxiliary cooler ( 22) and the expansion valve (25), after passing through the evaporator (30) and through the subcooler (22) flows to the compressor (10), during heating, the refrigerant compressed in the compressor (10) is the solenoid valve (12) After passing through the evaporator 22 and flows through the expansion valve 25 and the subcooler 22 to the condenser 21 through the heating auxiliary condenser 40 integrally formed in the evaporator 30, the sub-cooler 22 It is configured to flow to the compressor 10 via.

Here, the auxiliary cooler 22 is composed of a double pipe so that the refrigerant passing through the condenser 21 or the expansion valve 25 flows inward and the refrigerant passing through the evaporator 30 or the auxiliary heating condenser 40 flows outward. To cool the refrigerant to be used.

The refrigerant passing through the subcooler 22 is applied to the distributor 28 from the expansion valve 25 after passing through the filter drier 15 and the solenoid valve 16 or the solenoid valve 26 and the manual expansion valve 27. Through the distributor 28 is configured to be applied.

Such a constant temperature air conditioner (1) of the present invention is to be used for heating and cooling, during cooling the refrigerant of the compressor 10 through the condenser 21, the expansion valve 25 and the evaporator 30, the compressor (10) In the heating, the refrigerant of the compressor 10 passes through the evaporator 30, the expansion valve 25, and the condenser 21, and then flows through the heating auxiliary condenser 40 to the compressor 10.

It looks at the cooling operation of the present invention.

At cooling, the solenoid valves 11 and 16 are opened, and the solenoid valves 12 and 26 are closed.

Then, the refrigerant compressed by the compressor 10 warms the water in the water tank 74 through the humidification subsidiary condenser 20, cools the refrigerant through the condenser 21, and then cools the refrigerant again in the auxiliary cooler 22. After the expansion by expanding from the expansion valve 25 to supply the evaporator 30 from the distributor 28 to lower the temperature of the indoor air in the evaporator 30 and then discharged to the blower fan 6 to lower the room temperature, The air covered while passing through the condenser 21 is discharged to the outside via the exhaust port (7).

At this time, the blocking plate 46 of the duct 45 switches the air passing through the condenser 21 to the exhaust port 7.

The moisture contained in the indoor air during the operation of the evaporator 30 is condensed on the surface of the evaporator 30 to fall into the condensate, and the condensate at this time is collected from the drain 73 to the water tank 74.

On the other hand, if the room humidity drops during operation of the evaporator 30, the humidification auxiliary condenser 20 is operated to warm the water in the water tank 74 to evaporate the condensed water and the vapor evaporated by the humidification auxiliary condenser 20. After passing through the humidifying tube 71 is introduced into the room by the blowing fan 73 to increase the indoor humidity, a small blowing fan at the tip of the humidifying tube 71 in which the vapor evaporated from the water tank 74 is introduced (73) is fitted so that steam can easily enter the room.

Next, look at the heating time.

At this time, the solenoid valve 11 is closed and the solenoid valve 12 is opened.

Then, the refrigerant of the compressor 10 flows into the evaporator 30 so that the evaporator 30 serves as a condenser during cooling, and the refrigerant passing through the evaporator 30 passes through the expansion valve 25 and the auxiliary cooler 22. After coarse, the condenser 21 is applied to the condenser 21 to serve as an evaporator during cooling, and the refrigerant passing through the condenser 21 increases the refrigerant temperature in the heating auxiliary condenser 40 and then the heating auxiliary cooler 22. It passes through the compressor 10 through.

During heating, the refrigerant compressed by the compressor 10 flows into the evaporator 30 so that the evaporator 30 functions as a condenser so that hot wind is blown, and the refrigerant passing through the evaporator 30 and passing through the condenser 21 is cooled. If the air flows into the compressor 10 as it is, the refrigerant cycle cannot be compressed at a proper pressure (15 kg / cm 2) in the compressor 10 in the winter when the temperature is cold, and thus the refrigerant cycle does not operate normally. In the present invention, the condenser 21 is cooled in the condenser 21. Through the heating auxiliary condenser 40 formed integrally with the evaporator 30 to cover the refrigerant by the heat of the evaporator 30, the refrigerant can be compressed in the compressor 10 at an appropriate pressure even in winter.

Therefore, during heating, the evaporator 30 dissipates heat like a condenser so that heating is possible, while heating the refrigerant flowing through the heating auxiliary condenser 40 so that the compressor 10 does not freeze in winter and performs normal refrigerant compression. do.

At this time, the pipe of the evaporator 30 and the pipe of the heating auxiliary condenser 40 are installed in close contact with each other to heat the heat generated from the pipe of the evaporator 30 to heat the refrigerant flowing through the pipe of the heating auxiliary condenser 40. .

On the other hand, if the heating auxiliary condenser 40 alone is not enough to increase the temperature of the refrigerant to operate the electric heater 50 to cover the indoor inlet air, while the refrigerant is heated to ensure that the refrigerant is compressed normally.

In addition, the blocking plate 46 installed in the duct 45 of the present invention can switch the air passing through the condenser 21 to the outside or the room, and during heating, the air passing through the condenser 21 falls out. If you want to go out, but lower the room temperature to enter the room to lower the room temperature.

The electric heater 50 generates heat from the semi-conductive polymer 53 during electric conduction to heat the heat medium oil 54 to dissipate heat through the heat generating rod 51 to which the heat dissipation fins 52 are attached. The electric heater 50 is raised to a desired temperature while passing.

On the other hand look at the case of dehumidification while cooling in the present invention as follows.

In the case of cooling, in order to perform dehumidification, the heating auxiliary condenser 40 may be operated.

Then, the heating auxiliary condenser 40 operates to cool the indoor air in the evaporator 30 so that the air temperature is increased to achieve a dehumidifying effect. If the dehumidification is not possible even with the heating auxiliary condenser 40, the electric heater 50 is removed. Operate to allow dehumidification.

The check valve 13 of the present invention is installed to allow the refrigerant to flow in one direction.

The auxiliary cooler 22 is made of a double pipe to allow the refrigerant passing through the condenser 21 to flow into the inner pipe and the refrigerant passing through the evaporator 30 to reduce the temperature of the refrigerant through the condenser 21. This is possible because the refrigerant temperature passing through the evaporator 30 is lower than the refrigerant temperature.

The manual expansion valve 27 of the present invention is used to remove the frost when the evaporator 30 is formed. If the frost is formed on the evaporator 30, the solenoid valve 26 is opened and the evaporator 30 is then used. By lowering the speed of the refrigerant flowing into the evaporator 30 by lowering the evaporation effect is eliminated defrost.

The manual expansion valve 27 is manually operated to maintain the refrigerant supply amount set once, and the presence or absence of the refrigerant supply is selected by the solenoid valve 26.

Therefore, in order to remove the defrost of the evaporator 30, the solenoid valve 26 may be opened, and the flow rate of the refrigerant is selected by the manual expansion valve 27.

In the integrated constant temperature air conditioner, the refrigerant is introduced into the evaporator during heating so that the evaporator acts as a condenser during cooling, thereby raising the temperature of the air passing through the evaporator so that the heating is performed, while operating the heating auxiliary condenser, the refrigerant temperature. After it was introduced into the compressor to solve the problem of not being able to compress at the appropriate pressure due to the low refrigerant temperature in winter.

Therefore, the present invention can use both the constant temperature air conditioner for cooling and heating, and by using the refrigerant passed through the evaporator during heating to increase the refrigerant temperature before entering the compressor to maximize the thermal efficiency, the condenser acts as an evaporator during heating Since it is possible to remove the frost by simply changing the flow of refrigerant when the frost is stuck in the evaporator.
