ていることを特徴とする空気調和装置。[Claims for Utility Model Registration] In an air conditioner equipped with a refrigerant circuit 9 that connects a compressor 1, a heat source side heat exchanger 3, a pressure reduction section 50, and a user side heat exchanger 6 and can be switched to a forward/reverse cycle. , The pressure reducing section 50 includes a receiver 4 for storing liquid refrigerant, and an electric expansion valve 5 whose one end is connected to the lower part of the receiver 4.
Only the refrigerant is allowed to flow between the upper part of the heat exchanger 3 on the heat source side and the upper part of the receiver 4 and the heat exchanger 6 on the user side, respectively, from each of the heat exchangers 3 and 6 to the receiver 4. First and second check valves D 1 , D 2
between the other end of the electric expansion valve 5 and the heat source side heat exchanger 3 and between the other end of the electric expansion valve 5 and the utilization side heat exchanger 6 from the electric expansion valve 5 to each side. The upper part of the receiver 4 and the electric expansion valve 5 are connected to each other through third and fourth check valves D 3 and D 4 that allow only the flow of refrigerant to the heat exchangers 3 and 6. An air conditioner characterized in that the liquid pipe at the other end is connected to the liquid pipe via a capillary tube C having a degree of pressure reduction greater than that of the electric expansion valve 5.
