摘要： No studies have been made regarding what kinds of refrigerants should be used in a refrigeration cycle device for a vehicle. An air conditioner (1) for a vehicle includes a refrigerant circuit (10) and a refrigerant that is sealed in the refrigerant circuit (10). The refrigerant circuit (10) includes a compressor (80), a first heat exchanger (85), which serves as a heat dissipater in a dehumidifying heating mode, an outside-air heat exchanger (82), a cooling control valve (87), and a second heat exchanger (86), which serves as an evaporator in the dehumidifying heating mode. The refrigerant is a refrigerant having a low GWP.

摘要： A refrigeration apparatus pertaining to the invention can suppress clogging due to polymers formed by the polymerization of refrigerant and improve safety. The refrigeration apparatus is equipped with a refrigeration cycle in which a compressor, a condenser, an expansion mechanism, and an evaporator are connected in a loop. The refrigeration apparatus is equipped with a polymer catcher. The polymer catcher is attached to piping interconnecting an outlet side of the compressor and an inlet side of the condenser and chemically catches polymers of refrigerant circulating in the refrigeration cycle. The refrigerant includes a compound represented by a molecular formula having one or more carbon-carbon unsaturated bonds. The polymer catcher is a dryer that has an adsorbent that adsorbs the polymers.

摘要： A refrigeration apparatus (100) includes a heat source unit (10), a utilization unit (20A), and a liquid refrigerant pipe (31) and gas refrigerant pipe (32). The utilization unit (20A) has utilization unit internal pipelines (29a to 29c). The liquid refrigerant pipe (31) and the gas refrigerant pipe (32) connect the heat source unit (10) and the utilization unit internal pipelines (29a to 29c). A refrigerant circulates through the heat source unit (10), the utilization unit (20A), the liquid refrigerant pipe (31), and the gas refrigerant pipe (32). The refrigerant contains a compound represented by a molecular formula having one or more carbon-carbon unsaturated bonds. A disproportionation inhibitor for reducing a disproportionation reaction of the refrigerant is applied to at least a part of inner surfaces of the liquid refrigerant pipe (31), the gas refrigerant pipe (32), and the utilization unit internal pipelines (29a to 29c).
