Abstract:

A drying system and a laundry treatment apparatus comprising same, aiming to solve the problem of long drying time and power wastage in existing heat pump clothes dryers. The drying system comprises: a refrigerant circulation loop, comprising a compressor (11), a condenser (12), a throttling element (13) and an evaporator (14); and an air circulation loop, comprising a drying chamber (21), a gas-liquid heat exchanger (23), the evaporator (14) and the condenser (12). The drying chamber (21) has a wet air outlet (211) and a dry air inlet (212). The wet air outlet (211) communicates with an inlet of the evaporator (14), an outlet of the evaporator (14) communicates with an inlet of the condenser (12), and an outlet of the condenser (12) communicates with the dry air inlet (212). A water-receiving tray (31) is disposed below the evaporator (14). A refrigerant pipe (15) between the condenser (12) and the throttling element (13) comprises a first pipe section (151). The first pipe section (151) is provided in the water-receiving tray (31). The invention improves the heat exchange performance of the evaporator (14), shortens the drying time, and reduces drying energy consumption.
