Chilled water system components

Chilled water system components

What are the Common applications of a chilled water system? What is a system that uses heat to create chilled water called? What refrigerant is used in chilled water? How does a chiller system work? In this article we will learn how to locate these on the chiller and briefly what their purpose is. video tutorial at the bottom of the page.


Chilled Water Cooling System Components refrigerant maintenance containment, energy efficiency, and low installed cost chilled and condenser water pumps , cooling towers, heat exchangers, and hydronic specialties including water pressure regulators, air separators, and chemical feed pots. 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. Typically used for cooling and dehumidifying a building’s air, chilled water ( CHW ) systems circulate it throughout a building or campus complex.


CHW systems also may be used for removing process or other heating loads. Systems that employ water chillers are commonly called chilled-water systems. When designing a chilled-wat er system , one of the first issues that must be addressed is to determine which type of water chiller to use.

This period discusses the primary differences in chiller types. Your HVAC system deserves Carrier components. Carrier offers compressors, compressor units, condensing units, water cooled condensers , and chiller barrels for commercial air conditioning and refrigeration applications. They can be used to replace or enhance mechanisms within existing systems or to create custom solutions for new applications. Because the system cannot deliver hot water or chilled water simultaneously to the coils, it must be in either the heating or cooling mode.


To change over from heating to cooling , the water in the mains must be completely circulated through the chiller and back to the unit before any cooling is available at the zones. This chilled water is pumped to various floors of the building and its different parts. An efficient means of generating hot water is through the heat reclaim capabilities of Carrier’s 19DV and series water-cooled chillers.


Carrier chillers with heat reclaim capabilities can produce chilled water controlled to the necessary temperature while generating hot water as a by-product of the chilled water system. Chilled water systems are popular because they use water as a refrigerant. As its name suggest, this system makes use of water as its secondary refrigerant. Chiller is used to remove heat from the water which is then circulated through other components to absorb heat from the space. While the upfront cost of a water chilled system can be a lot, the greater energy efficiency and lower maintenance costs usually make up for it.


This cool fluid removes heat from the process and the warm fluid returns to the chiller. The process water is the means by which heat transfers from the process to the chiller. When the load on the coil is zero, the valve is returning “unused” chilled water at essentially supply temperature. Cold return water “unloads” the chillers, causing them to operate inefficiently. A chilled water system is a cooling system in which chilled water is circulated throughout the building or through cooling coils in an HVAC system in order to provide space cooling.

The density, and therefore the volume, of the water in a “closed” chilled-water distribution system varies as it undergoes changes in temperature. Multi pump systems have primary chilled water pumps and secondary chilled water pumps. Primary chilled water pump flows water through the evaporator side of the chiller. Secondary pumps flow water through AHU’s Condenser pumps flow water over the cooling tower to remove heat from the machine. Cooling water is water used as a heat-transfer medium to carry heat away from one or more parts of a system.


I have a Closed loop chilled water system , its a Primary (constant Speed) and (Secondary variable Speed) System , all the Pumps and the Chilled are located at the Roof Top and the Loads(ahus,fcu) at Ground level.
