Chilled Water Coil Piping Schematic

The water quantity used in chilled water systems is usually considerably higher than that used for heating because the unit coils work on smaller temperature differentials in the cooling mode than in the heating mode.

Chilled water coil piping schematic. In this article we l be covering chilled and condenser water schematics to learn how to read them how to identify the main components and symbols as well as real world examples additionally we ll cover the purpose of the main components and different design types. Multiple cell cooling tower. Pitot test connections. The schematic shown omits the isolation valves that are.

Figure below shows the schematic of the constant flow rate primary system. Terminal unit water coils piping connections. Water cooled chiller piping connections. Analyzed with pipe flo engineered software olympia wa 1 800 786 8545.

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. 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.

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. Control diagram overflowand drain piping same size as tower connection pipe equalizing line between towers locate connection per the tower mfr s recommendations. 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. Technically speaking water can be classified as a refrigerant.
