WebJul 7, 2024 · An economizer control is a mechanical device that uses cool outside air to cool inside a building, thus reducing the need for electrical cooling. The control is installed as a part of the ventilation/cooling system. … Energy used by the compressor accounts for most of the total electricity consumed. WebOct 27, 2024 · How do Chillers Work - Screw Compressors. A pair of matched helical rotors are machined to a high tolerance. One of them is driven by a motor and the other one interlocks with it. The gap between the rotors gets smaller as the refrigerant continues down the screw and so compression is achieved. Oil is injected into the screw to provide a seal ...
