REFRIGERATION UNIT OF REFRIGERATOR CONTAINER Russian patent published in 2021 - IPC F25B1/00 

FIELD: refrigeration equipment.

SUBSTANCE: device relates to refrigeration equipment; it can be used for providing a required temperature mode in a cargo volume of a refrigerator container. A refrigeration unit of a refrigerator container contains a compressor connected to a capacitor, a receiver installed behind the capacitor and connected to a thermal expansion valve, an evaporator-air cooler, a regenerative heat exchanger providing heat exchange between refrigerant vapors coming from the evaporator and a liquid refrigerant coming from the capacitor, a filter-dryer and a moisture content indicator, sequentially arranged after the receiver, a control unit and temperature sensors. The unit additionally contains a radiator connected to the capacitor, a heat exchanger connected to the radiator, a liquid pump supplying the refrigerant from the radiator to an additional heat exchanger and the capacitor, electromagnetic valves installed with the possibility of connecting the heat exchanger to the radiator and the pump, a bellows installed on the radiator and connected to it, a temperature relay rigidly fixed on the compressor and connected to the control unit, an additional temperature sensor connected to the heat exchanger, a flow meter installed behind the liquid pump.

EFFECT: increase in the efficiency of the device operation.
