Air open circle heat pump type drying wardrobe

Abstract

The invention provides an air open circle heat pump type drying wardrobe. The air open circle heat pump type drying wardrobe comprises a drying room, an equipment room and a heat pump drying system which is arranged in the equipment room; the drying room is separated from the equipment room through a separation plate with a ventilation opening; an air inlet channel and an air outlet channel which are independent of each other are formed in the equipment room; an air inlet of the air inlet channel and an air outlet of the air outlet channel communicated with the external air; an air outlet of the air inlet channel and an air inlet of the air outlet channel are communicated with the drying room; the heat pump drying system comprises a condenser and an evaporator; the condenser is located in the air inlet channel and the evaporator is located in the air outlet channel; the outside air enters the air inlet channel to obtain the dry air to be conveyed to the drying room after being headed through the condenser; the moist air in the drying room is discharged onto the evaporator and condensed through the evaporator to separate the moisture to be discharged out of the equipment room through the air outlet channel. According to the air open circle heat pump type drying wardrobe, the problem of the invalid operation of the traditional heat pump drying system in the falling-rate drying stage is solved, meanwhile the heat and humidity emission is reduced, and the energy-saving effect is achieved.

Description

technical field [0001] The invention relates to the technical field of drying device design, in particular to an air open circuit heat pump drying cabinet. Background technique [0002] Heat pump, as a heat transfer tool, as a device to improve the low-grade heat quality of soil, air, and water to obtain higher-grade heat, under the background of energy saving and emission reduction, in the fields of heating, hot water, drying, etc. , has gained more and more widespread application. The essence of heat pump energy saving is to inject a small amount of electric energy to drive the compressor. Through the suction and exhaust operation of the compressor, the low-pressure refrigerant gas that absorbs a large amount of low-grade heat in the evaporator is compressed into high-pressure gas and enters the condenser to achieve high temperature. Exothermic. [0003] Usually, the ratio of the heat output power of the heat pump condenser to the electric power sucked by the compressor ...

AI Technical Summary

Problems solved by technology

If there is no heat release and condensation of water vapor on the evaporator, the drying and dehumidification in the deceleration drying stage will not be completed, and the "last mile" problem of drying wet clothes will not be solved; the high-temperature air continues to circulate in a closed circuit, but the heat pump system Continued ineffective operation at "high temperature"
