Chiller Cooling Tower Design

Design and operation cooling tower fundamentals.

Chiller cooling tower design.

Chillers absorb heat from a coolant which is fully contained in a cooling system. Though chillers and cooling towers perform similar functions they vary according to their types and components used and the nature of the equipment they cool and power. In the illustration above we have shown the main chiller components. The compressor which is the driving force of the refrigerant around the system.

An hvac heating ventilating and air conditioning cooling tower is used to dispose of reject unwanted heat from a chiller water cooled chillers are normally more energy efficient than air cooled chillers due to heat rejection to tower water at or near wet bulb temperatures air cooled chillers must reject heat at the higher dry bulb temperature and thus have a lower average reverse.

Depending on the scale and layout of a building multiple chillers and cooling towers may be needed. System sizes complexity.

For example a dedicated system for a server room may run independently from the rest of the building. The condenser which removes the unwanted heat from the system and send this to the cooling tower. Besides air cooled chiller topchiller also provides water cooled chiller and cooling tower. This kind of water cooled chiller works with a proper cooling tower and circulation water pump to make a complete water cooling system.

The chiller then transfers heat to the air around the chiller unit. Design and operation 2005. A trane engineers newsletter live cooling towers and condenser water systems.
