RefrigerationQuestion 54 of 110
What is the primary function of the compressor in the refrigeration cycle?
a.To absorb heat from the space
b.To meter refrigerant into the evaporator
c.To raise the pressure and temperature of the refrigerant vapor and circulate it
d.To drain condensate
Explanation
The compressor draws in low-pressure vapor from the evaporator and compresses it to a high pressure and temperature, then discharges it to the condenser. This pressure difference drives refrigerant flow around the loop. It is often called the heart of the system.
