A typical chilled water system is designed to operate with what leaving water temperature?

In a typical chilled water system, the leaving water temperature is usually set around 45°F. This temperature balance is crucial for effective cooling while ensuring the system operates efficiently.

At 45°F, the system can adequately remove heat from the spaces being cooled while also minimizing the risk of condensation on cooling coils, which can lead to moisture-related issues. This temperature allows the chilled water to absorb enough heat from the environment it is cooling and still return to the chiller at a temperature that allows for effective re-cooling without causing strain on the system.

In addition, this temperature range strikes a balance that allows the system to function within optimal performance parameters while also maximizing energy efficiency. Therefore, a leaving water temperature of 45°F is considered standard practice in designing chilled water systems.
