Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/021083
Kind Code:
A1
Abstract:
A refrigeration cycle device comprises a compressor (11), a condenser (12), a first pressure reduction unit (13), an outdoor heat exchanger (14), a second pressure reduction unit (15), and an evaporator (16). When a prescribed site from among the sites through which refrigerant flows from the condenser to the first pressure reduction unit serves as a condenser outlet (12, 12e, 123, 13c, 32), a prescribed site from among the sites through which refrigerant flows from the first reduction unit to the outdoor heat exchanger serves as an outdoor heat exchanger inlet (13f, 14g, 33), and a prescribed site from among the sites through which refrigerant flows from the outdoor heat exchanger to the second pressure reduction unit serves as an outdoor heat exchanger outlet (14h, 14i, 14p, 14s, 142, 143, 144, 15c, 34, 35), the capacity of the condenser outlet is larger than the capacity of the outdoor heat exchanger inlet. According to this refrigeration cycle device, a favorable coefficient of performance for the cycle can be achieved in different operation modes.
