Water Cooled Chiller Piping Diagram

I ll show you some examples of how chillers are illustrated in schematics as it really varies.

Water cooled chiller piping diagram.

The two in the top right and the one in the bottom right are all air cooled chillers and the rest are water cooled. 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. Drake chillers is the industry leader in the design and manufacturing of industrial process chillers. Ily chilled water and condenser water system piping system design it is important to understand the evolution from 1 pipe into the other three systems all of which are used for heating as well as cooling.

Chillers can be either air or water cooled. Major vapor compression chiller components include an evaporator compressor s condenser and expansion device s figure 1. The principal objectives of chilled water pumping system selection and design are to provide the required cooling capacity to each load to promote the efficient use of. A water cooled chilled water plant consists of a water cooled chiller typically located inside the building.

This manual discusses the chiller s evaporator and condenser and their relationship to the chilled water. We ll first start with the chiller. Chilled water schematic examples different chiller representations. The water cooled condenser is typically part of a water cooled chiller or water cooled package unit a cooling tower rejects the condenser heat to the atmosphere flow rates and temperatures are industry standards for north america piping and pumps circulate water water is reused and exposed to the ambient conditions in the.

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. They also can be placed outside the building and include chilled water pumps an expansion tank an air separator chemical treatment cooling towers located outside of the building condenser water pumps makeup water to accommodate evaporation of the condenser water and chemical. The chilled water leaves the. The evaporator of the chiller is where the chilled water is generated.

For the remainder of this article we will focus on water cooled chillers and cooling towers.
