Evaporator Temperature

This is the temperature of the refrigerant in the evaporator coil, where it absorbs heat from the process or space being cooled. It typically ranges from 40°F to 50°F (4°C to 10°C) for most chillers.

Condenser Temperature

This is the temperature of the refrigerant in the condenser coil, where it releases absorbed heat to the surrounding environment. For air-cooled chillers, this temperature can range from 85°F to 105°F (29°C to 41°C). For water-cooled chillers, it is usually lower, depending on the cooling water temperature.

Chilled Water Temperature

This is the temperature of the water or coolant that is circulated through the chiller to absorb heat. Typically, the chilled water temperature is maintained between 44°F and 54°F (7°C to 12°C), depending on the specific application and requirements.

Setpoint Temperature

The setpoint temperature is the temperature that the chiller is set to maintain in the cooling process. It is adjustable based on the needs of the system being cooled. Accurate control of this temperature is crucial for efficient operation and maintaining desired conditions.

Delta T

This refers to the temperature difference between the inlet and outlet of the chilled water or refrigerant. A proper delta T helps in assessing the performance and efficiency of the chiller.

Understanding and controlling chiller temperatures is essential for maintaining optimal performance, efficiency, and longevity of the chiller system.
