FIELD: cooling systems. SUBSTANCE: compensation space 6 is in communication with evaporator 1 through pipe line 7 having controlled valve 8. Evaporator 1 is connected with condenser 2 through pipe lines 3. Thermoelectric cooler 9 is connected with space 6 through the cold junction and to evaporator 1 through the hot junction and heat conductor 10. Micro-cooler 9 is connected with valve 8 through control unit 11. The control unit is constructed as commutation unit and its normally open contacts are connected to the supply circuit of cooler 9 and normally closed contacts to the supply circuit of valve 8. EFFECT: enhanced efficiency. 2 cl, 3 dwg
