Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2021/149247
Kind Code:
A1
Abstract:
An air conditioner (1), comprising: a refrigerant circuit (2) configured to circulate a refrigerant through a compressor (10), a condenser (40), an LEV (111), and an evaporator (20); a first temperature sensor (102) that detects the temperature of the liquid refrigerant on the inlet side of the evaporator (20); and a control device (200) for controlling the compressor (10) and the LEV (111). If the temperature (T1) detected by the first temperature sensor (101) is lower than a frost formation assessment temperature, the control device (200) causes the opening degree of the LEV (111) to be greater, and causes the operation frequency of the compressor (10) to be higher, than if the temperature (T1) detected by the first temperature sensor (101) is higher than the frost formation assessment temperature.
