Abstract
PURPOSE: In the proposed controlling device for a refrigerant of an air-conditioner system which uses common throttle unit for the cooling and heating operations, a bypass circuit with an electromagnetic valve is provided as the throttle unit so as to switch-over the bypass circuit in accordance with the differential pressure between sides of a high-pressure and a low-pressure of the compressor. Under the above arrangement, aimed at is to enable the bypass circuit to perform sufficient enough cooling and heating capabilities.
