Water-cooled chillers are almost always located inside of a building. They work almost the same way as air-cooled chillers. The difference is that they remove heat from chilled water by exhausting the heat to a second, isolated water line called the condenser water line. Air conditioning- Types, Diagram, Working, Applications Components of the air conditioning system. The basic components of the air conditioning system are, 1.Fans: For circulation of air 2. Filters: For cleaning air 3. Heating element: Heating of air (It may be an electric heater, steam, hot water) 4. Control system: It regulates automatically the amount of cooling or heating. 5. PDF HVAC Chilled Water Distribution Schemes - CED Engineering chilled water flow through the cooling coil is restricted (in response to supply air temperatures to the space) but the total quantity returned to the chiller remains constant. Figure below shows the schematic of the constant-flow rate primary system. Chilled Water Schematics - The Engineering Mindset The chilled water is generated and circulated in the primary side, the secondary loops will pull chilled water out of the header to cool the building and then dump the warm return back into the header. If the flow rate In the secondary side is low then some chilled water will flow into the secondary and some will recirculate back to the chillers.

Chiller water systems - slideshare.net ADVANTAGES OF CHILLER WATER AIR CONDITIONING SYSTEMS • THE EVAPORATOR COOLS WATER TO ABOUT 45 .THAT CHILLED WATER IS PUMPED TO COOLING COILS IN THE AREAS BEING COOLED, AND A FAN DRAWS THE AIR IN THOSE AREAS THROUGH THE CHILLED WATER COILS, COOLING THE AIR.
