Chiller is a device that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle.

• Chiller absorbs heat from a process water stream and transfers it to a refrigerant.

• The refrigerant then carries the heat to the condenser where it is released.

• The chilled water is circulated through the building to cool the air or equipment.

• Chillers can be air-cooled, water-cooled, or evaporatively cooled.

• Commo...read more

Maintain differential pressure by adjusting airflow, sealing leaks, and monitoring equipment.

• Adjust airflow using dampers or variable frequency drives to balance pressure

• Seal leaks in ductwork or building envelope to prevent pressure loss

• Monitor equipment regularly to ensure proper functioning and make adjustments as needed

Cooling tower discharge pressure is the pressure at which water is discharged from the cooling tower.

• Cooling tower discharge pressure is typically measured in pounds per square inch (psi) or inches of water column (in. WC).

• The discharge pressure is influenced by factors such as the flow rate of water, the height of the cooling tower, and the design of the tower.

• Maintaining the correct discharge pressure is important fo...read more
