Thermo-hygrostat having heat storage tank and cool storage tank

摘要

The present invention relates to a constant temperature and humidity chamber provided with a heat storage tank and a cold storage tank. More particularly, the present invention relates to a thermo-hygrostat for cooling and heating and humidifying, A refrigeration cycle including a compressor, a condenser, an expansion valve, and an evaporator, in which refrigerant sequentially circulates, is configured to assist the cooling and heating of the thermo-hygrostat using the refrigerator; An evaporator 120 and an evaporator 120. The evaporator 120 and the electric heater coil 130 are connected to the evaporator 120 and the electric heater coil 130, An indoor unit 100 including an air blower 140 for supplying indoor air to the room; An outdoor unit 200 including the compressor 210 and the condenser 220 and a fan 230 for blowing outside air to the condenser 220; A heat storage tank (300) composed of a heat-sealed container and storing hot water by heating a feed water from a high-temperature refrigerant supplied from the condenser (220) to the expansion valve (110) as a heat source; A cold storage tank (400) which is made of a heat-sealed container and stores cold water by cooling the low-temperature refrigerant supplied from the evaporator (120) to the compressor (210) as a heat source; A cold / hot water coil 500 located in the indoor base 100 and performing heat exchange between the hot water supplied from the thermal storage tank 300 or the cold water supplied from the axial cold storage tank 400 and the supply air; A hot water pump 600 for sending hot water in the thermal storage tank 300 to the cold / hot water coil 500; A cold water pump 700 for feeding cold water in the axial cold storage tank 400 to the cold / hot water coil 500; And a three-way valve 800 for selectively returning hot water or cold water by selectively connecting any one of the heat storage tank 300 and the axial cold storage tank 400 from the cold / hot water coil 500. The evaporator and the electric heater coil So that the power consumption required for cooling and heating can be remarkably reduced to reduce the cooling and heating cost of the user, while maximizing the merchantability and the market competitiveness of the facility.
