Danfoss medium temperature refrigeration compressor M series

liquid 1. Liquid back: When the refrigerant returned to the compressor is not a pure gas state, but contains liquid, the influence of the liquid refrigerant on the compressor is negative. If there is too much liquid, it may even cause liquid shock, even if there is no liquid shock, it will happen. Wet compression causes oil to run away.

Types of refrigeration compressors for industrial chillers

The energy efficiency ratio of the chiller compressor of the chiller unit determines the energy efficiency ratio of the entire refrigeration system. Since the ambient temperature changes, the compressor is in a partial load state most of the time, so the compressor must have energy regulation.
