Description

Indoor Standing Power-Saving Constant Temperature and Humidity Structure {STRUCTURE OF STANDING-TPYE POWER SAVING THERMOHYGROSTAT}

The present invention relates to a thermo-hygrostat, and more particularly, it is installed in a room and inhaled indoor air, and then heated, chilled, dehumidified, or humidified according to a set temperature or a set humidity and then indoors. It is related to indoor standing thermo-hygrostat to keep indoor temperature and humidity constant.

The thermo-hygrostat varies depending on whether the outside air is inhaled, the installation location of the heat dissipation capacitor (integrated and separate), the cooling method of the heat dissipation capacitor (air-cooled and water-cooled), the separation of the evaporator and other refrigeration cycles, and the installation position relative to the room. Are classified.

In particular, the present invention has a compressor, an oil separator, a receiver, and a filter drier inside a housing that can be installed on a floor in a room. It has all parts necessary for heat pump cycle such as expansion valve, evaporator, accumulator, heating heater, dust filter, blower, humidifier, etc. The present invention relates to an indoor standing thermo-hygrostat which includes only an outdoor unit and inhales indoor air and then heats, chills, dehumidifies, or humidifies it according to a set temperature or a set humidity.

In general, the thermo-hygrostat is equipped with a hot gas controller, which detects when the temperature or humidity of the room is out of the error range than the set temperature or the set humidity, and automatically cools, heats, dehumidifies, or humidifies the operation. Will be

The room where the thermo-hygrostat is installed is mainly a room equipped with a system or device that generates a lot of heat, such as a computer room, a precision measurement room, an engine laboratory, a clean room of a semiconductor factory, an electromagnetic plate production room, and thus, cooling, dehumidifying and humidifying operation are mainly used. In winter, they can be heated as needed. The heating operation in the conventional indoor standing constant temperature and humidity chamber was performed by stopping the refrigeration cycle, operating only the heating heater, and circulating the indoor air by the blower. However, such heating heater heating not only takes a long time to reach the set temperature, but also has a disadvantage in that the efficiency is consumed and consumes a lot of power.

In the conventional indoor standing thermo-hygrostat, the cooling is provided in the housing according to a normal refrigeration cycle, a compressor for compressing the gas refrigerant to high temperature and high pressure, an oil separator for separating the oil of the compressed gas and returning it to the compressor, outdoor A heat dissipation capacitor (outdoor unit), which is provided in the chamber and is compressed in a compressor and introduced into a liquid refrigerant having a high temperature / high pressure and is introduced into the evaporator by phase change into a liquid refrigerant at room temperature and high pressure, and is provided inside the housing and phase-changed from the outdoor unit to the liquid state. A receiver that stores refrigerant and discharges it to the evaporator, a filter drier that filters foreign matter from the liquid refrigerant flowing into the evaporator, and a low temperature room temperature that is easy to evaporate from the evaporator by dropping the pressure of the liquid refrigerant before sending the liquid refrigerant at room temperature and high pressure. Valves for converting liquid refrigerant into liquid refrigerant Distributor distributed to the tube, evaporator to cool the air passing through the surroundings while vaporizing the introduced refrigerant, and the accumulator to vaporize the unvaporized refrigerant to the compressor in order to circulate sequentially. Air is introduced into the evaporator to remove heat and then back to the room. Particularly, the condenser and the evaporator of the components of the refrigerating cycle cause changes in the state of the refrigerant, and these state changes are all called by heat exchangers between the refrigerant inside the refrigerant pipe and the external air space outside the refrigerant pipe. The condenser heats the gas of the high temperature and high pressure gas refrigerant from the compressor with the ambient air, thereby making the liquid refrigerant at room temperature and high pressure, and thus can be used to heat the ambient air.

In addition, in the conventional indoor standing thermo-hygrostat, the dehumidification is performed to cool the indoor air in the evaporator while condensing by dew point phenomenon while performing the above-mentioned cooling operation, and collecting the same in a drain pan to discharge it through a drain. In this case, since the air temperature is cooled below the dew point temperature of the set room humidity (usually around 12 ° C), it must be reheated to the set room temperature (usually around 22 ° C) and discharged to the room. At this time, in reheating the air from which the cooling was removed, conventional heating heaters, such as an electric heating heater and a steam heater, were used. However, to increase the air temperature more than 10 ℃ instantaneously, a large amount of heat is required, and thus there is a problem that excessive power consumption occurs in the heating heater.

The present invention devised to solve the excessive power consumption problem of the conventional indoor standing thermo-hygrostat has a purpose to provide a power-saving thermo-hygrostat with a structure that can minimize the power consumption during heating operation and reach a set temperature in a short time. have.
