Abstract
In a refrigeration cycle in which a capacity-variable compressor a condenser, an expansion mechanism and an evaporator are connected in the order named, a device for controlling the capacity in the refrigeration cycle comprising a means for detecting the temperature of the compressor or the temperature of the gas discharged therefrom and a control device for limiting the maximum rotational speed of the compressor when the output from the means for detecting the temperature indicates a detected temperature lower than a predetermined level.
