In a water cooled condenser, the refrigerant condensing temperature should not be more than how many degrees higher than the leaving water temperature?

In a water cooled condenser, the refrigerant condensing temperature should ideally be no more than 10°F higher than the leaving water temperature. This is important because maintaining this temperature differential ensures efficient heat transfer from the refrigerant to the cooling water. If the refrigerant condenses at significantly higher temperatures relative to the leaving water, it can lead to decreased condensation efficiency and may even cause the condenser to operate outside its optimal range, potentially resulting in increased pressure and higher energy consumption.

Keeping the temperature difference within this 10°F limit ensures that the condenser can effectively reject heat while maintaining system efficiency. It also helps to prevent issues such as excessive wear on the compressor and reduced overall cooling capacity. Operating within this range allows the system to maintain optimal performance and reliability.
