Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/098655
Kind Code:
A1
Abstract:
In this refrigeration cycle device (100), a refrigerant circulates in the order of: a compressor (1); a condenser (2); a first expansion valve (4); and an evaporator (5). The refrigeration cycle device (100) is equipped with a first bypass flow path (11). The first bypass flow path (11) branches off from a first flow path connecting the compressor (1) and the condenser (2), and is connected, with a second valve (7) interposed therebetween, to a second flow path connecting the condenser (2) and the first expansion valve (4) or a third flow path connecting the evaporator (5) and the compressor (1). The opening degree of the second valve (7) in the cases when the evaporation temperature in the evaporator (5) is less than a first reference value is larger than that in the cases when the evaporation temperature is more than the first reference value.
