Actually, the pressure difference in the refrigeration cycle has been substantially eliminated, and therefore, the sound generated by the influence of the flow of the refrigerant when switching the four-way valve 2 is considerably small, and in some cases, the sound is completely muted. . In the above embodiment, the drive control method of the present invention is described during the heating operation. However, in other operation modes, the operation at the time of startup is exactly the same as that in the above-described heating operation. is there. However, during the cooling operation, the changeover switch 2a of the four-way valve 2 is turned on at the time t4 as shown by a broken line in FIG.

In the case of ending the operation in the connected state, the changeover switch 2a of the four-way valve 2 remains connected to the heating operation side (in the above embodiment, the solenoid is turned on). In this case, as shown by the broken line in FIG.
In 2, the changeover switch 2a of the four-way valve 2 is switched to the cooling operation side. Subsequent control is exactly the same as in the above embodiment.
