Chilled Water Air Conditioning Principles And Appliions
How Chilled Water Air Conditioning Works Chiller The chiller is the section of the system where an exchange of heat occurred between the water that goes to the building and the evaporator The water leaves the chilled water evaporator at 45 176F or 7 176C This chilledwater is then circulated through the entire building by the use of a pump

About Chilled Water Systems HVAC Hydronics
About Chilled Water Systems HVAC Hydronics Conclusion The water is pumped to the cooling tower outside where the water releases heat and is returned to the heat exchanger where the cold water absorbs heat from the chilled water return Coming out of the heat exchanger is a chilled water supply pipe that is delivered to the load through the chilled water supply
