How does “pump down” work in commercial refrigeration?

Описание: 💡How does “pump down” work in commercial refrigeration? ç

Controlled temperature triggers the thermostat...
▶️ which opens or closes refrigerant flow to the evaporator.
▶️ The compressor pumps down the evaporator...
▶️ and switches off at the low-pressure set point.

So you use fewer switches, save energy, and never risk liquid flow to the compressor.
