Title:
AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/163339
Kind Code:
A1
Abstract:
The air-conditioning device (1) is configured so as to circulate a nonazeotropic refrigerant mixture through a compressor (110), a first heat exchanger (120), a second heat exchanger (130), a first expansion valve (140), and a third heat exchanger (150) in this order. A notification unit (13) is configured so as to provide a warning notification to a user if a first refrigerant ratio determined from a first difference between a first temperature (T1) and a second temperature (T2) and a second difference between a third temperature (T3) and a fourth temperature (T4) is different from an appropriate value. The first temperature (T1) is the temperature of the nonazeotropic refrigerant mixture between the first heat exchanger (120) and the second heat exchanger (130). The second temperature (T2) is the temperature of the nonazeotropic refrigerant mixture between the second heat exchanger (130) and the first expansion valve (140). The third temperature (T3) is the temperature of the nonazeotropic refrigerant mixture between a first decompressor (141) and a first junction (JC). The fourth temperature (T4) is the temperature of the nonazeotropic refrigerant mixture between a second decompressor (142) and the first junction (JC).
