Type III — Low-Pressure第 177 / 240 题
Low-pressure chillers most commonly use which type of compressor?
a.Centrifugal
b.Rotary vane
c.Scroll
d.Reciprocating hermetic
解析
Low-pressure chillers typically use centrifugal compressors, which move large volumes of low-pressure refrigerant vapor to cool commercial buildings. Reciprocating, rotary, and scroll compressors are more common in higher-pressure and smaller systems. Recognizing the centrifugal chiller helps identify Type III equipment.
