A water-cooled condenser that is operating properly will have what characteristic regarding discharge water temperature?

The characteristic of discharge water temperature in a properly operating water-cooled condenser is that the discharge water is typically about 10 degrees warmer than the condenser temperature. This occurs because as the refrigerant condenses in the condenser coils, it absorbs heat from the refrigerant and transfers this heat to the water flowing through the condenser.

The condenser's role is to remove heat from the refrigerant, and the water utilized for cooling will come into contact with the coils, absorbing some of that heat. Therefore, upon leaving the condenser, the discharge water will exit at a temperature that is higher than the temperature of the refrigerant within the condenser, reflecting the energy that has been transferred to the water.

This principle is fundamental in understanding how water-cooled systems operate, as it illustrates the efficiency of heat transfer in refrigeration systems.
