Fresh Storage Cold Room Electrical

Fresh storage cold room — regulating band operation.

Storage temperature cycles between:

-2°C → cooling starts
3°C → cooling stops (pump-down)

Cold room control logic.

→ Thermostat calls for cooling
→ Liquid solenoid energises
→ Suction pressure rises
→ Low pressure switch cuts in
→ Contactor energises
→ Compressor starts

A simple control sequence
behind every cooling cycle.
