Chilled water coil piping schematic.

Technically speaking water can be classified as a refrigerant. Pitot test connections. 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 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.

Control diagram overflowand drain piping same size as tower connection pipe equalizing line between towers locate connection per the tower mfr s recommendations. The pipe sizing is based on a maximum of 10 feet per second max velocity. Terminal unit water coils piping connections. Figure below shows the schematic of the constant flow rate primary system.

Chilled water schematic and condenser water schematics. Natural gas and liquefied petroleum gas burner and igniter fuel standard piping diagram. The 1 pipe system is poorly suited to chilled water distribution for several reasons. 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.

Multiple cell cooling tower. Analyzed with pipe flo engineered software olympia wa 1 800 786 8545.

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. 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. The base scenario consists of 6 160 gpm coils selected for 15 ft of water pressure drop.
