For a water-cooled condenser, the condensing temperature should be:

• A. At the same level as leaving water temperature
• B. 5 degrees higher than leaving water temperature
• C. 10 degrees higher than leaving water temperature
• D. 15 degrees higher than leaving water temperature

Answer: (C)

For a water-cooled condenser, the ideal condensing temperature is typically around 10 degrees higher than the leaving water temperature. This principle is based on the need to maintain efficient heat transfer between the refrigerant and the cooling water. When the refrigerant vapor enters the condenser, it must lose heat to the cooling water to condense effectively. If the refrigerant condenses too close to the water temperature, there may be insufficient temperature difference to facilitate effective heat transfer. This leads to reduced efficiency and unit capacities. Having the condensing temperature set at a level around 10 degrees higher than the leaving water temperature ensures that there is an adequate temperature gradient for effective heat exchange. This allows the condenser to operate efficiently, helping maintain system performance and reliability.
