Abstract (en)
[origin: EP3358273A1] Provided is a heat pump use apparatus, including a refrigerant circuit, a heat medium circuit, and a heat exchanger configured to exchange heat between refrigerant and a heat medium. A main passage of the heat medium circuit includes a branching portion and a joining portion. A pressure protection device and a refrigerant leakage detection device are connected to the main passage. The pressure protection device is connected to the main passage at a connecting portion located between the heat exchanger and one of the branching portion and the joining portion. A first interruption device configured to be able to interrupt a flow from the heat exchanger to the connecting portion is provided in the main passage at a portion between the heat exchanger and the connecting portion. A second interruption device configured to be able to interrupt a flow from the heat exchanger to an other of the branching portion and the joining portion is provided in the main passage at a portion between the heat exchanger and the other of the branching portion and the joining portion.
