A reciprocating compressor changes the refrigerant state by doing what?
a.Condensing vapor to liquid
b.Metering liquid flow
c.Using pistons to compress low-pressure vapor into high-pressure vapor
d.Boiling the refrigerant
Giải thích
A reciprocating compressor uses pistons driven by a crankshaft to draw in and compress refrigerant vapor, raising its pressure and temperature. Scroll and rotary compressors accomplish the same result by different mechanisms. The compressor circulates refrigerant and establishes the high and low sides.
