Typically, refrigeration compressor systems run at the same fixed rate year-round. During the winter when it is cooler, the outdoor cold air takes the heat away from the condenser at a quicker rate and the system can still perform at a lower pressure. Lowering the pressure saves energy and compressor wear and tear.

WebJun 4, 2007 · A style of head pressure control valve for low-ambient conditions (Figure 1) has a round pressurized dome at its top that is pressure charged. This valve is often referred to as a low-ambient control (LAC) valve. This dome charge is independent of the refrigerant charge in the actual refrigeration system. WebThe growing global demand for energy and the costly taxes on electric energy demonstrate the importance of seeking new techniques to improve energy efficiency in industrial facilities. Refrigeration units demand a large amount of electricity due to the high power needs of the components of the system.
