Chiller Plant Chilled Water System Diagram

How does a chiller work.

Chiller plant chilled water system diagram.

Chilled water systems provide cooling to a building by using chilled water to absorb heat from the building s spaces. In most process cooling applications a pumping system circulates cool water or a water glycol solution from the chiller to the process. Chilled water schematic and condenser water schematic how to read and understand the engineering drawings with real world examples illustrations animations and video tutorial. However the purpose of a chiller remains the same.

If the water flows along tube side and the refrigerant along the shell side it is called as the flooded chiller. System flow below chiller min flow 250 gpm variable primary flow at 25 system load two way valves control capacity by varying flow of water in coils per chiller system load 50 tons 176kw 50tons 176 kw primary bypass flow 250 gpm 95 l s 150 gpm 9 5 l s delta t 12 of 6 7 oc 100 gpm 44 ºf 6 3 l s 6 7 ºc 56 ºf 13 3 ºc 150. Covering chillers pump sets ahus risers primary and secondary systems cooling towers and bypass lines. The process water is the means by which heat transfers from the process to the chiller.

How a chiller works. This cool fluid removes heat from the process and the warm fluid returns to the chiller. At the heart of the water chilled system a chiller removes heat from water by means of a refrigeration cycle. To remove heat from water.

Chilled water plant system diagram exercise this is an updated version of an exercise i originally published on the blog back in september of 2013. The process fluid absorbs heat from what is being cooled and then goes through the chiller where the heat is removed from the fluid and transferred to the. The water chilled in the chiller is pumped to various parts of the building that are to be air conditioned. The plant operators turn on extra chillers and associated pumps to provide the needed capacity.

The chilled water flows up the height of the building to each floor in pipes known as risers. The chilled water leaves the evaporator at around 6 c 42 8 f and is pushed around the building by the chilled water pump. Chilled water system basics. I posted it to provide an on line version of an exercise i had done in class which was the first time i had tried using a sketchup model as a teaching aid.

To put it simply industrial chillers cool process fluids. The evaporator of the chiller is where the chilled water is generated. This means not only the delivered capacity of the chillers is reduced but also.
