Title:
冷凍サイクル装置の制御方法
Document Type and Number:
Japanese Patent JP7367213
Kind Code:
B2
Abstract:
In a refrigeration cycle apparatus (1), a refrigerant pipe (31) is connected to a compressor (3), a first heat exchanger (5), an expansion valve (9), a second heat exchanger (11), a heat absorber (17), and the compressor (3) sequentially in this order. R290 is used as refrigerant flowing through the refrigerant pipe (31). The heat absorber (17) is provided in a portion of the refrigerant pipe (31) between the compressor (3) and the first heat exchanger (5) or the second heat exchanger (11) serving as an evaporator. The heat absorber (17) is disposed in contact with an electric component (19a). A branch pipe (33) is connected in parallel with the portion provided with the heat absorber (17) in the refrigerant pipe (31). The branch pipe (33) is provided with a flow rate regulating valve (21).
