FIELD: agriculture.
SUBSTANCE: device comprises a receiverof natural cold, located outdoors and provided with the outdoor temperature sensor, coolant temperature sensor with low freezing point, a fan for cooling the intensification of environmentally safe refrigerant with low freezing point. The receiver is connected via a solenoid valve and a bypass channel with an inlet coolant with a low temperature heat exchanger of the first freezing section. Output passage opening is connected to the receiver of the natural cold and forms a second closed loop of a heat exchanger. A temperature sensor of the environmentally safe refrigerant with a low freezing point is set at the outlet passage opening . Solenoid valves, pumps, fans, outdoor temperature sensor, temperature sensors of the environmentally safe refrigerant with a low freezing point are electrically connected to the control unit.
EFFECT: improved the reliability and energy efficiency of the installation.
