How Cooling Towers Work (W/ Diagram, Pictures & Principles .

The water is exposed to air as it flows throughout the cooling tower. The air is being pulled by an motor-driven electric "cooling tower fan". When the air and water come together, a small volume of water evaporates, creating an action of cooling. The colder water gets pumped back to the process/equipment that absorbs heat or the condenser.

Chilled Water System Basics [HVAC Commercial Cooling]

Chilled Water System Basics - Chilled water systems in residential HVAC systems are extremely rare. A typical chiller uses the process of refrigeration to chill water in a chiller barrel. This water is pumped through chilled water piping throughout the building where it will pass through a coil.

How Does A Chiller Work? - What Is A Chiller & How To .

There are two types of condensers used in chillers; air-cooled and water-cooled. An air-cooled condenser uses ambient air to cool and condense the hot refrigerant gas back down to a liquid. It can be located inside the chiller or can be remotely located outside, but ultimately it rejects the heat from the chiller to the air.

Chilled Water System Commissioning: Variable Primary Flow

Limit the speed at which the chilled water pump VFD's can speed up and down • Limit the time span the chilled water flow control valve actuators can stroke from min to max • Review the system dP's and how the pumps track to maintain the lowest from setpoint • Put in a dead band so the pumps are not always hunting due to system size and
