Abstract
A control unit is disclosed for controlling a refrigerating machine in such a way that a refrigerating power exceeding the required performance is secured while the control unit has a function of bypassing hot gas by means of a hot gas bypass line. A temperature-responsive valve is mounted in the hot gas bypass line in addition to a pressure regulating valve. If a preset temperature Tr of a brine becomes equal to or higher than a given temperature (0° C.), the temperature-responsive valve opens the bypass line. If the preset temperature Tr becomes lower than the given temperature, the temperature-responsive valve closes the bypass line.
