Abstract:
A drying system, and a laundry treatment apparatus comprising same. The drying system comprises: a refrigerant circulation loop comprising a compressor (11), a condenser (12), a throttling element (13) and an evaporator (14); an air circulation loop comprising a drying chamber (21), a gas-liquid heat exchanger (23), an evaporator (14) and a condenser (12), an air inlet (2311) of the gas-liquid heat exchanger (23) being in communication with a moist air outlet (211) of the drying chamber (21), an air outlet (2312) of the gas-liquid heat exchanger being in communication with an inlet of the evaporator (14), an outlet of the evaporator (14) being in communication with an inlet of the condenser (12), and an outlet of the condenser (12) being in communication with a dry air inlet (212) of the drying chamber (21); and a cooling circulation loop comprising a water pan (31), a water pump (32) and a gas-liquid heat exchanger (23), a liquid inlet (2313) and a liquid outlet (2314) of the gas-liquid heat exchanger (23) separately being in communication with the water pan (31), and the water pump (32) being arranged between the liquid outlet (2314) and the water pan (31). The dehumidification capacity of the evaporator (14) is thus ensured, the drying time is shortened, and the drying energy consumption is reduced.
