媒循環量（流量）を少なくする必要がある。Conventionally, such a circuit is configured, but the amount of control of the refrigerant flow rate is different during cooling and during heating. That is, during cooling, since the evaporation capacity in the indoor heat exchanger 7 is large, the refrigerant passes only through the cooling/heating capillary tube 4, passes through the cooling check valve 6, and flows to the indoor heat exchanger 7, increasing the amount of refrigerant circulation. When heating,
Since the evaporation capacity of the outdoor heat exchanger 3 that acts as an evaporator is small, it is necessary to control it with the heating capillary tube 6 and further control with the cooling/heating capillary tube 4 to reduce the refrigerant circulation amount (flow rate). be.

なって適切な冷媒制御が行なわれる。In the above configuration, for example, during heating, the indoor heat exchanger 1
The refrigerant condensed in step 6 passes through refrigerant pipe 17 and reaches control valve 1.
5. In the control valve 16 shown in FIG.
The refrigerant flowing in from the inlet/outlet 31 passes through the refrigerant flow hole 29 of the valve body B28 and presses the movable valve 23. By pressing, the movable valve 23 moves toward the entrance/exit 32 side, and the valve body A1
The valve seat portion 27 of No. 9 is closed. Therefore, the refrigerant is transferred to the movable valve 23
The refrigerant flows through the pores 26, and at this time, the passage cross-sectional area becomes smaller, causing a pressure drop in the refrigerant.Furthermore, since it passes through the cooling/heating capillary tube 14 (Fig. 2), the refrigerant flows through the indoor heat exchanger 16 and , the pressure drop between the outdoor heat exchangers 13 acts as a dog, and appropriate refrigerant control is performed.

, it flows into the movable valve chamber 22, further presses the movable valve 23 toward the valve body B28, and moves to the stopper 3o position,
Stop. In the stopped position, the refrigerant flows through the protrusion 24
The refrigerant passes through a large-flow refrigerant flow path 26 provided between the refrigerant and the refrigerant flow hole 29 of the valve body B2B, and flows into the indoor heat exchanger 16 through the inlet/outlet 31. That is, during cooling, since the refrigerant flows through the refrigerant flow path 25, the passage cross-sectional area becomes larger than during heating, and a predetermined cooling pressure drop is controlled by the cooling/heating capillary tube 14.

A movable valve that is movable within a room due to a refrigerant pressure difference and has a pore in the center and a plurality of protrusions on the outer circumferential surface, and a movable valve that is provided at the other end of the valve body A and that one end of the movable valve is in contact with. A valve body B having a stopper and a refrigerant flow hole is provided, and during cooling, the refrigerant flow path is passed between the protrusions provided on the movable valve, and the passage cross-sectional area is set as a dog.
During heating, the movable valve contacts the valve seat of the refrigerant flow hole of the valve body A to close the large flow rate and allow it to flow through the fine hole;
Since the passage cross-sectional area is small, there is almost no pressure drop during cooling, and a predetermined pressure drop can be produced during heating, eliminating the need for capillary tubes for heating as in the past. This eliminates the need for branch pipes between the capillary tube for heating and the check valve for cooling, resulting in significant cost reductions, and the refrigerant circuit can be configured simply, requiring less piping space in air conditioners, etc. It has practical effects such as:
