Chiller Cooling Tower Design

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

Chiller cooling tower design.

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. Design and operation cooling tower fundamentals. The condenser which removes the unwanted heat from the system and send this to the cooling tower. System sizes complexity.

The chiller then transfers heat to the air around the chiller unit. After cooling off a bit the condenser water returns to the condenser cylinder at about 80 degrees f. The expansion valve which expands the refrigerant and controls the superheat into the compressor and the evaporator which collects the unwanted heat.

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. Besides air cooled chiller topchiller also provides water cooled chiller and cooling tower.

For example a dedicated system for a server room may run independently from the rest of the building. This kind of water cooled chiller works with a proper cooling tower and circulation water pump to make a complete water cooling system. Water cooled chiller cooling capacity from 2ton to 65ton and water cooling tower from 30ton to 380ton.
