The present invention relates to an air conditioner for controlling room temperature and humidity by cooling and dehumidifying indoor air.

Conventional thermo-hygrostat is cooled by normal cooling principle that cools by cooling the room heat in the endothermic condenser in the evaporator and cooling the room heat in the endothermic condenser even when cooling, because there is a large amount of heat generated like a computer room or a machine room even when the outside air temperature is low in winter. When dehumidifying, electric or steam heaters were used to heat the air cooled in the evaporator.

For the same reason as above, even when the outside air temperature is low, the refrigerator is operated like the summer season without cooling the outside air, and the power consumption is high, and the power consumption is high because it is heated by electricity, steam, or heater during dehumidification.

In order to reduce the excessive power consumption of the cooling and dehumidifying apparatus described above, the present invention cools indoor air by using a cold heat source of the outdoor air when the outside air temperature is lowered below a certain level like in winter, and the waste heat source of the heat medium heated in the condenser during dehumidification. Since it is used for heating to achieve a dehumidification purpose even without a separate heating source of electricity or steam, the driving power of the thermo-hygrostat is significantly reduced as described in detail with reference to the accompanying drawings as follows.

1 is a freezer and heat medium (antifreeze) circulation cycle of the present invention, the indoor air is circulated through the filter (5) evaporator (4) heat exchanger (6) when the blower (7) operates, the refrigeration cycle is a compressor (I) Is operated, the refrigerant of the condenser 2 is operated in a normal refrigeration cycle in which the air is cooled in the evaporator 4 through the expansion valve 3 and then circulated to the compressor I.

The cooling of the condenser 2 is cooled by the heat medium (antifreeze), and the heat medium is cooled by the outside air with the air volume of the cooling fan (II) in the cooler IO and circulated by the pump 9.

The valve 8 switches the flow path of the heat medium at the outlet of the condenser 2 to the heat exchanger 6 and the cooler IO. When the valve 8 is opened to the heat exchanger 6, the freezer is stopped by an external air temperature sensor and the cooler IO Cool with heat medium cooled to) and reheat with heat medium heated in condenser (2) during dehumidification.

Moreover, it is the flow path change valve 8 of a heat medium so that it may cool to the heat medium which opened to the cooler IO and cooled the condenser at the time of cooling by a normal cooling cycle.

Referring to the operation method of the device of the present invention configured as described above in detail in connection with the temperature and humidity change, First, when cooling the refrigerator with a high outside air temperature, such as summer, when the compressor (I) and the blower (7) is operated refrigerant By the normal refrigeration cycle circulated to the condenser (2) expansion valve (3) evaporator (4) compressor (I), the indoor air is cooled in the evaporator (4) and supplied to the room through the blower (7) to achieve the cooling purpose do.

At this time, since the heat exchanger 6 is closed and opens toward the cooler IO, the valve 8 is cooled by the heat medium cooled in the cooler IO.

Second, in the case of cooling by the cold heat source of the outside air, when the outside air temperature winding is below a certain level, the compressor (I) is stopped and the valve (8) is switched to the heat exchanger (6), so that the heat medium cooled by the outside air in the cooler (IO) Circulates into the pump (9) condenser (2) valve (8) heat exchanger (6) cooler (IO), so the cooled heat medium cools the room air by the heat exchanger (6), so it is not cooled in the evaporator (4) of the freezer. Even if the indoor air can be cooled, the power of the conventional refrigerator is unnecessary, and thus a lot of power is saved.

Third, when operating for the purpose of dehumidification because the humidity is high, if the freezer is operated by a normal freezing cycle, the indoor air is cooled by the dew point phenomenon at the same time as the air is cooled in the evaporator 4, but at the same time, the air temperature drops and the relative humidity is In order to achieve the purpose of dehumidification, this low temperature and high humidity air must be heated. At this time, the valve 8 is opened on the heat exchanger 6 side and the cooler (IO) side is closed by sensing the room temperature and humidity. Therefore, the heat medium heated by cooling the condenser 2 heats up in the heat exchanger 6 to heat the air cooled in the evaporator 4 to achieve the purpose of reheating, and after heat radiating and cooling the residual heat through the cooler IO, the pump ( 9) After forming the circulation cycle to cool the condenser 2, the air cooled in the evaporator is dehumidified by heating the heat medium heated in the condenser during dehumidification. Since the purpose is achieved, there is no need for electricity or steam heater for heating, which can save a lot of power.

As it operates according to the structure and principle as described above, the constant temperature and humidity device under the condition that cooling is required even in winter such as computer room or machine room, or the humidity needs to be controlled by dehumidification. When it is lowered, it does not operate the refrigerator but achieves the purpose of cooling by using the cooling heat of the outside air to save power and heats the heat of the heat medium heated in the condenser as a heating source during dehumidification. It works.
