Understanding the Role of a Refrigeration Compressor
A refrigeration compressor is the heart of any cooling system. It performs three key functions:
- Compresses low-pressure refrigerant vapor into high-pressure gas
- Circulates refrigerant throughout the system
- Maintains the pressure difference needed for heat absorption and rejection
The ADW77 compressor, with its 1/4HP capacity, is designed for medium-temperature refrigeration applications where consistent cooling is required without high energy consumption.
