The waste heat recovered from a commercial refrigeration system typically consists of either only the
heat which is required to desuperheat the compressor discharge gas, or both the heat required to
desuperheat the discharge gas as well as the heat required to condense the refrigerant from a saturated
vapor to a saturated liquid. The waste heat from the former is known as desuperheating waste heat
while that from the latter is known as full condensing waste heat. Less waste heat is recovered through
only desuperheating as compared to full condensing, however the quality of the heat recovered by only
desuperheating is higher, i.e., the temperature of the waste heat from desuperheating is higher than
that obtained from full condensing.
