4 Chiller System Design and Control SYS-APM001-EN Primary System Components Some chiller controls can accommodate very little flow variation during machine operation.2 Other, more sophisticated, chiller controls allow some flow variation. Some chille rs can tolerate flow-rate variations—as much as 50
A chiller is made up of the 4 major components required for the refrigeration process which are: a) compressor, b) condenser, c) evaporator and d) expansion valve. To produce chilled water, the refrigerant absorbs heat from the water and thus, chilling the water to about 6.7C (44F).
A chiller unit is a cooling mechanism designed to produce fluids that can lower temperatures by removing heat from the fluid. The type and use of a chiller depends on the required temperature and kind of refrigerant, which can be a liquid or a gas. The cooled fluid is used to cool a room or piece of equipment.

Mar 01, 2016 Cooling towers are used in water-cooled refrigeration, industrial process systems and commercial HVAC air-conditioning. A simple way to appreciate how a cooling tower works is to consider the “beach effect.”. On a 95F (35C) day with 95 percent humidity, a dip in the water is incredibly refreshing.
Mar 01, 2016 The Cooling Cycle of an HVAC Chiller. Compressor to Condenser: The compressor sends hot refrigerant gas to the condenser, where the refrigerant’s heat is transferred to the cold water outside the component. As it cools, the refrigerant turns into a liquid. Condenser to Metering Device: The metering device limits the flow of the liquid ...
Mar 24, 2020 Secondary wastewater treatment processes heavily rely on the use of bacteria to eliminate organic matter from sewage. Common methods involve the use of trickling filters, activated sludge, and sodium hypochlorite injection. In most cases, the bacteria used in water treatment plants function optimally at temperatures between 68F and 95F.

Water-cooled chillers use water to surround the refrigerant pipes and draw in the heat (path shown in red). The water is then pumped into a cooling tower to release the heat. After condensing, the refrigerant goes through an expansion valve to reduce pressure (and temperature) before returning to the evaporator, where the process begins again.
