Refrigeration第 70 / 110 题
A compressor that is trying to compress liquid refrigerant returning from the evaporator can suffer what damage?
a.Improved efficiency
b.Higher superheat
c.Slugging and mechanical damage to valves or bearings
d.Lower amp draw
解析
Liquid refrigerant is nearly incompressible, so liquid floodback or slugging can damage compressor valves, bearings, and rods. Maintaining adequate superheat prevents liquid from reaching the compressor. This is why superheat is carefully controlled.
