How much higher is the condensing temperature in a water cooled condenser compared to the leaving water?

In the context of refrigeration systems, particularly those utilizing water-cooled condensers, the condensing temperature is critical for understanding the efficiency and performance of the refrigeration cycle. The condensing temperature in a water-cooled system is typically several degrees higher than the temperature of the leaving water from the condenser.

The value of 10°F reflects the general rule of thumb in refrigeration, indicating that the condensing temperature will be approximately 10°F warmer than the temperature of the water exiting the condenser. This difference arises from the heat transfer processes involved; as the refrigerant releases heat to the water, it will always be slightly warmer than the water due to thermal dynamics and the efficiency of heat exchange.

Therefore, when considering the operating conditions in a water-cooled system, it's reasonable to conclude that a difference of around 10°F between the condensing temperature and the leaving water is representative of typical performance metrics in refrigeration applications.
