OPERATION OF AMMONIA REFRIGERATION SYSTEMS

Mechanical refrigeration is a process for exchanging heat to effect a desired temperature in an environment and/or an end product. The state-of-the-art in current mechanical refrigeration technology involves the transfer of the refrigerant through its liquid and vapor states by mechanical compression, condensation, and evaporation.

Chapter 4 Cryogenic Refrigeration Systems

Jul 29, 1980 · Cryogenic Refrigeration Systems 161 failures in the drive units of the refrigerators. The compressors that supplied high-pressure helium gas to the antenna-mounted Cryodynes® often contaminated the helium with the lubricant used in the compressor. The expression “oil carry-over” was used often when reporting Cryodyne® warm-ups (failures).
