At what temperature does the low stage compressor suction operate normally?

The low stage compressor suction in an industrial refrigeration system typically operates around -38°F. This temperature is associated with systems using ammonia or other refrigerants where lower temperatures are necessary to efficiently absorb heat from the environment being refrigerated. This operation allows the compressor to effectively vaporize the refrigerant within the evaporator, thus ensuring optimal cooling performance.

The selection of -38°F aligns with the typical operational parameters needed for processes requiring deep cooling, such as freezing applications in food processing or storage. Understanding this temperature range is crucial for maintaining system efficiency, as well as ensuring proper function and longevity of the refrigeration equipment.

In contrast, higher temperatures like -30°F do not provide the necessary cooling capacity for all applications within an industrial setting, while temperatures such as 24°F and 22°F are much more suitable for systems operating at higher pressures and would not be standard for low stage compressors where significant cooling is required.
