Title:
HEAT-SOURCE-SIDE UNIT AND REFRIGERATION CYCLE APPARATUS COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2020/217423
Kind Code:
A1
Abstract:
A heat-source-side unit (2) constituting a refrigeration cycle apparatus (1) comprises: a bypass circuit (BC) configured to return a portion, of refrigerant exiting a condenser (20), to a compressor (10) without passing through an evaporator (60); and a heater (72) for heating refrigerant flowing through a pipe constituting the bypass circuit. A control apparatus (100) assesses whether the amount of refrigerant with which a refrigerant circuit (RC) has been filled is suitable on the basis of a temperature increase amount constituted by the difference between the temperature of the refrigerant before being heated by the heater (72) and the temperature of the refrigerant after being heated.
