AIR HEAT SOURCE HEAT PUMP DRIER WITH SWITCH FUNCTION OF DIRECT CONNECTION-TYPE CONDENSER FOR DEHUMIDIFICATION COOLING AND DEHUMIDIFICATION HEATING IN DRIER

摘要

The present invention relates to an air heat source heat pump drier with a switch function of a condenser. More specifically, the air heat source heat pump drier condenses a refrigerant in a low temperature and low pressure in an evaporator in a heat pump to perform dehumidification by performing heat exchange with the refrigerant by a condition of air circulated in a drying chamber and stops the flow of a refrigerant in a high pressure and high temperature in a condenser, or condenses a refrigerant in a low pressure and low temperature in an evaporator by performing heat exchange with the refrigerant in a low temperature and pressure in the evaporator, so the refrigerant in the high pressure and temperature in the condenser flows to preform heat-exchange with the refrigerant in the high pressure and temperature and increase the temperature of refrigerant, and then the refrigerant is circulated into a drying chamber. Thus, the air heat source heat pump drier can increase drying efficiency of a drier and stability of a heat pump. Therefore, the air heat source heat pump drier with a switch function of a condenser selectively switches a first condenser and a second condenser by an air temperature condition in the drying chamber, forms a cooling dehumidification operation or a heating dehumidification operation by a single operation or co-working operation of an evaporator, changes the capacity of an inverter fan of the first condenser, and stably operates the cycle of a heat pump, thereby optimally operating efficiency of a drier.;COPYRIGHT KIPO 2017
