Product Operation Principle

Industrial chillers utilize electricity as the power source, where the refrigerant absorbs heat from the chilled water or antifreeze in the evaporator to achieve cooling. After evaporating and absorbing heat, the wet steam refrigerant is compressed into a high-pressure gas by the compressor. It is then condensed into a liquid in the condenser and throttled by the expansion valve before entering the evaporator for recirculation. This process produces chilled water at temperatures ranging from 5°C to 12°C (or lower) for use by the end-user.
