Occasionally while servicing refrigeration equipment, technicians may come across a system utilizing a water-cooled condenser instead of an air-cooled condenser. Water is a much better heat transfer fluid than air, as its specific heat value is 1 Btu/lb. compared to 0.24 Btu/lb. for air. However, the cost of operating a water-cooled system is generally higher, making it an uncommon choice in many refrigeration systems.
