Claims

[Scope of Claim for Utility Model Registration] 1. In a refrigeration cycle in which a floor panel heat exchanger for floor heating is interposed in refrigerant piping together with an indoor heat exchanger, the refrigerant is not supplied to the indoor heat exchanger during heating operation. The floor panel heat exchanger is interposed in the refrigerant pipe on the upstream side of the flow direction, and a bypass pipe is provided in the refrigerant pipe to communicate the refrigerant inflow side and the refrigerant outflow side of the floor panel heat exchanger, during cooling operation. A check valve is provided in each of the bypass piping and the refrigerant inflow side of the floor panel heat exchanger so that the refrigerant bypasses the floor panel heat exchanger and flows through the bypass piping. refrigeration cycle. 2 A two-way valve is interposed in the refrigerant pipe connected to the refrigerant inflow side during heating operation in the floor panel heat exchanger, and a check valve is oriented in a direction to prevent refrigerant from flowing into the refrigerant inflow side. A refrigeration cycle according to claim 1, which is provided in parallel with the two-way valve. 3 An on-off valve is installed on the outdoor side heat exchanger on the downstream side in the direction of refrigerant flow during cooling operation, and a check valve is installed on the suction side of the refrigerant in the compressor along the refrigerant suction direction. A refrigeration cycle according to claim 1 of the utility model registration claim. 4 Both ends of the floor panel heat exchanger are connected to the refrigerant piping via a half union, and the indoor heat exchanger is connected to the refrigerant piping through a packed valve on the refrigerant inflow side and a half union on the refrigerant outflow side during cooling operation. A refrigeration cycle according to claim 1 of the utility model registration, which is connected to a refrigeration cycle.
