Description

Refrigerant a cooling device thermohygrostat

The present invention relates to a constant temperature / humidity device which is equipped with a compressor, a condenser, and an evaporator, and controls the temperature and humidity of a room constantly. The present invention relates to a refrigerant cooling device of a thermo-hygrostat that improves the efficiency of the condenser, reduces the load of the exhaust fan, and reduces power consumption by providing a temperature lowered to a predetermined temperature by a heat-pipe cooling device.

In particular, the computer room equipped with a computer or electronic equipment, etc. should keep the indoor temperature and humidity optimally, for this purpose it is common to install a constant temperature and humidity in the computer room.

The present applicant has been patented as patent No. 260036, an integrated thermo-hygrostat, which is very easy to install because the compressor, the condenser and the evaporator are integrally mounted in the main body, and thus the compressor and the condenser are not required to be installed outdoors.

The applicant's patented integrated thermo-hygrostat is configured to perform indoor humidification by using the heat of the condenser, and also cools the condenser through the exhaust fan and discharges the heat of heat to the outside.

1 is a schematic main configuration diagram of an integrated thermo-hygrostat, which includes a compressor 10 for compressing a low-temperature, low-pressure gaseous refrigerant, and an exhaust fan having a high-temperature, high-pressure compressed refrigerant installed in a main body. A heat-dissipation auxiliary condenser 11 for forced cooling by liquefaction, a humidifier 12 for heating and evaporating water by the heat of discharge of the humidification sub-condenser 13 to which high-temperature, high-pressure refrigerant is conveyed, and liquefaction by a condenser. An expansion valve 14 and a distributor 15 for expanding and supplying the refrigerant to an evaporation pressure, an evaporator 16 for cooling the indoor air by receiving a refrigerant having a low temperature and a low pressure by the expansion valve 14, and a high temperature. A heating auxiliary condenser 17 for releasing refrigerant heat to lower indoor humidity, an electric heater 18 for lowering humidity by heating indoor air with a heater, and a receiver and a filter are additionally installed.

The integrated thermo-hygrostat of this configuration uses a high-temperature refrigerant heat to heat the water to increase the indoor humidity while heating the indoor air to lower the humidity, forcibly cooling the condenser through the exhaust fan to discharge the heat released to the outside.

In addition, when the indoor temperature is lower than the appropriate temperature, such as in winter, the cooling cycle is operated in reverse, so that the high temperature and high pressure refrigerant is provided from the compressor to the evaporator to increase the indoor temperature by applying warm air to the room.

Existing integrated thermo-hygrostats reduce the refrigerant temperature in the heat-dissipation auxiliary condenser by driving the refrigerant at high temperature and high pressure.However, the refrigerant temperature is not sufficiently cooled. And this leads to a sharp increase in power consumption, causing problems in the maintenance of the thermo-hygrostat.

In other words, when the room temperature rises to 35 ℃ ~ 37 ℃ like in summer, the cooling cycle continues to operate to optimally lower the room temperature.In this case, if the cooling temperature of the refrigerant is not sufficiently cooled in the condenser, the cooling cycle is maintained at a high temperature. This is because there is a problem that the load is generated because the exhaust fan is excessively operated while the thermal efficiency is lowered.

Therefore, the present invention was devised to solve the problems of the existing integrated thermo-hygrostat as described above. The water-cooled cooling device which injects and circulates the water sufficiently cools the condenser and controls the humidity by introducing the vapor evaporated here. By using a heat-pipe cooling device in which heat exchange is carried out by evaporation and condensation of heat medium (freon gas, alcohol), the temperature of the refrigerant cooled in the condenser is lowered by a predetermined temperature to improve the efficiency of the condenser while loading the exhaust fan. To reduce power consumption and reduce power consumption.

According to the present invention, the cooling cycle is operated while the refrigerant is sufficiently cooled by the water-cooled cooling device and the heat-pipe cooling device, thereby improving the efficiency of the condenser and preventing excessive operation of the exhaust fan.
