Chilled Water Coil Piping Schematic

Control diagram overflowand drain piping same size as tower connection pipe equalizing line between towers locate connection per the tower mfr s recommendations.

Chilled water coil piping schematic. The schematic shown omits the isolation valves that are. The base scenario consists of 6 160 gpm coils selected for 15 ft of water pressure drop. Analyzed with pipe flo engineered software olympia wa 1 800 786 8545. Air cooled chiller piping connections.

Figure below shows the schematic of the constant flow rate primary system. Filter section raised floor return air computer room air conditioning unit supply air. The 1 pipe system is poorly suited to chilled water distribution for several reasons. The pipe sizing is based on a maximum of 10 feet per second max velocity.

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. 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. Po box 55 cheswick pa 15024 phone 724 274 5430 fax 724 274 5448. Water cooled chiller piping connections.

Technically speaking water can be classified as a refrigerant. Pitot test connections. Natural gas and liquefied petroleum gas burner and igniter fuel standard piping diagram. Chilled water schematic and condenser water schematics.

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. Chilled water system basics chilled water systems work much the same way as direct expansion systems work the exception is they use water in the coil rather than refrigerant.
