のよい使用ができる。When the air conditioner X is activated while the solenoid coil 17 of the pilot solenoid valve 14 is energized, the plunger 15 is attracted to move the valve body 16 to move the low pressure communication pipe 19 through the lumen 16a. since communicating the high-pressure supply pipe 21 to the conduit 20 for the pressure transducer chamber R 3 together to communicate with the conduit 22 to the pressure transducer chamber R 2, a high pressure is introduced pistons 12 to slide valve body 13 to the pressure transducer chamber R 3 is pressure Since it moves in the conversion chamber R 2 direction, the communication lumen 13a communicates the ports C and D, and the communication lumen 13b communicates the ports E and F (see FIG. 3),
The high pressure from the port A flows into the port B through the high pressure chamber R 1 and reaches the cooling operation position where the refrigerant circulates along the path shown by the solid line in FIG. In the structure of FIG. 1, the flow directions of the refrigerant in the outdoor heat exchanger 2 and the indoor heat exchanger 3 are always the same without changing during cooling and during heating, and efficient use of the heat exchanger is ensured. it can.

できる。Therefore, during the heating operation, the refrigerant circulates along the dotted line route in FIG. 4, and during the cooling operation, the refrigerant circulates along the solid line route. In the air conditioner Y, the direction of the refrigerant flow in the indoor heat exchanger 3 is reversed during heating and during cooling, so the efficiency is inferior accordingly, but since only one expansion valve is required, space and cost are saved. In terms of the reverse flow of the refrigerant, in particular, when the heating operation is switched to the cooling operation during the defrosting operation, the flow direction of the refrigerant in the outdoor heat exchanger 2 that is the object to be defrosted is constant. It is the same as the case of the air conditioner X in that it is possible to prevent the occurrence of the pressure fluctuation due to it and to speed up the start of the defrosting operation, and in this case as well, the electric expansion valve 6'is fully opened. Therefore, warm air can be continuously sent in the indoor heat exchanger 3.
