FIELD: motors and pumps.
SUBSTANCE: system comprises a pilot line (12), with the inlet (12a) to get refrigerant from the cooling system line (3) , and thermostatic regulator (6), comprising sensor (6b), designed with a possibility of refrigerant temperature monitoring in the pilot line (12), and the valve (6a). The cooling system comprises the heat device (13, 26, 31) contacting with refrigerant in the pilot line (12) located upstream the sensor (6b), and the control unit (15) designed with a possibility of assessment, when it is necessary to change the working temperature of the refrigerant in the cooling system, and, in such cases, actuating of the heat device (13, 26, 31), so that it heated or cooled the refrigerant in the pilot line (12).
EFFECT: invention ensures the improvement of reliability of refrigerant working temperature control.
