Abstract (en)

[origin: EP4060257A1] A detection case (20) is arranged between an outdoor heat exchanger (2) and an expansion valve (3). A diaphragm (23) divides an internal space of the detection case (20) into a first space (R1) and a second space (R2). The first space (R1) is sealed, and a second refrigerant (CB) of the same type as a first refrigerant (CA) is sealed in the first space (R1). The second space (R2) is connected to a refrigerant circuit (100), and the first refrigerant (CA) flows into the second space (R2). A strain sensor (GS) is arranged on the diaphragm (23) and detects a difference between a pressure of the first refrigerant (CA) in the second space (R2) and a pressure of the second refrigerant (CB) in the first space (R1). A temperature detector (51) detects a temperature of the first refrigerant (CA) between the outdoor heat exchanger (2) and the detection case (20).
