REFRIGERATION UNIT CONTROL CONTROLLER Russian patent published in 2024 - IPC F24F11/30 F25B49/02 

FIELD: control.

SUBSTANCE: invention relates to control of refrigerating units. Controller for controlling a refrigerating unit comprises a device for connecting to a data transmission network, memory for storing information, device for recording temperature values into controller memory, temperature sensors, freon high and low level pressure sensors, crankcase heating element control relay, cabinet heating element heating element, compressor control relay, evaporator fan control relay, door opening sensor, a transistor assembly connected on one side to a memory device made on the basis of a microcontroller, and on the other – with high and low level freon pressure sensors, crankcase heating element control relay, cabinet heating element, compressor control relay, fan control relay, door sensor. Microcontroller is made with possibility of recording into memory and comparison with preset parameters of freon pressure on high and low levels, checking signals from emergency sensors, controlling compressor, evaporator fan, crankcase heating element, cabinet heating element, door sensor.

EFFECT: expansion of control capabilities.
