What does de-superheating of the refrigerant do for the refrigeration cycle?
Rapid de-superheating of the refrigerant by means of water cooling results in a lower condensing head pressure and a cooler operating compressor. Lower head pressure results in lower power consumption by the compressor, and a lower compressor operating temperature results in a longer operating life expectancy for the compressor. This is another reason why water cooled (or geothermal) systems are so much more efficient than air cooled systems.
