Document Type and Number:
WIPO Patent Application WO/2022/068972
Kind Code:
A1
Abstract:
Provided are a drying system and a laundry handling device comprising said system. The invention aims to solve the problems of long drying time and high energy consumption of existing drying systems. The drying system comprises: a refrigerant circulation loop, comprising a compressor (11), a condenser (12), a flow-regulating element (13), and an evaporator (14); an air circulation loop, comprising a drying chamber (21), a gas–liquid heat exchanger (23), the evaporator (14), and a condenser (12); the air inlet (2311) of the gas–liquid heat exchanger (23) is in communication with a wet air outlet (211) of the drying chamber (21), the air outlet (2312) is in communication with the inlet of the evaporator (14), the outlet of the evaporator (14) is in communication with the inlet of the condenser (12), and the outlet of the condenser (12) is in communication with a dry air inlet (212) of the drying chamber (21); a cooling circulation loop, comprising a water receiving tray (31), a water pump (32), and the gas–liquid heat exchanger (23), the liquid inlet (2313) and liquid outlet (2314) of the gas–liquid heat exchanger (23) being in communication with a first part (312) and a second part (313) of the water receiving tray (31), respectively, a refrigerant tube (15) being partially coiled in the second part (313). The invention ensures the dehumidification capability of the evaporator (14), reducing energy consumption during drying.
