A1
Abstract:
This air conditioner comprises a refrigerant circuit in which a compressor, a condenser, an expansion unit, a receiver, and an evaporator are connected by piping, the refrigerant circuit being such that a refrigerant flows therethrough. The piping includes: heat-exchange piping provided to the center inside the receiver, the heat-exchange piping being such that refrigerant drawn in by the compressor flows within the heat-exchange piping, and performing heat exchange between the refrigerant therein and refrigerant that has accumulated in the receiver; and receiver piping inserted into the receiver. The receiver piping includes inflow piping of which one end is connected to the condenser and the other end is inserted into the outer-peripheral side of the heat-exchange piping inside the receiver, the inflow piping channeling refrigerant into the receiver. The other end of the inflow piping extends so as to follow a circumference centered on the heat-exchange piping.
