Chilled Water Coil Sizing Calculator

Coil load flow temperature difference wizard.

Chilled water coil sizing calculator.

Equations displayed for easy reference. The chilled water absorbs the heat from the building. The same equations apply for altitude however the true density must include db wb and pb altitude pb. For over 40 years our team at cold shot chillers have successfully sized quoted and built machines for many applications.

Water velocity feet per second fps water velocity fps gpm factor number of tubes fed tube diameter factor 5 8 od 1 085 1 2 od 1 704 3 8 od 3 050 as water velocity increases the capacity of a coil increases but so does the water resistance. Properly sizing a chiller for your application can depend on a large number of variables. The water flow rate of chilled water into the evaporator is 0 0995m3 s the inlet temperature is 12 c and the outlet temperature is 6 c. The chilled water circulates through a chilled water loop and through coils located in air handlers.

Flash steam per cent online calculator. This means the average temperature is 9 c so we lookup the water properties at this temperature to find the density of 999 78kg m3 and a specific heat capacity of 4 19kj kg k. Qwater 500 gpm leaving water temperature entering water temperature. The chilled water pump is a part of an overall chilled water system that often includes a chiller piping valves fittings expansion tank air handling units and fan coil units.

Coil programs use actual conditions. The chilled water pump is used to circulate chilled water in a closed system. At 57 50 db and 57 30 wb the w 0099622 lbw lba. Online calculator to quickly determine pipe sizing by velocity for water.

At 100 db and 78 wb the w 015601 lbw lba density 06914 ft lba. As you can see in the case of a hot water coil where the air is heated and the water is cooled the above equation will result in a negative q. Size steam supply pipe online calculator. Pb altitude is calculated from the.

The three systems available in this calculator are the 1 split system packaged a c 2 air cooled chilled water and 3 water cooled chilled water. However this guide focuses. This guide covers the design and selection of a chilled water pump. Chilled water cooling tower systems cooling tower npsh wizard.

It is a balance between the desired capacity and the resultant 20. The above shows a sea level calculation. In a chilled water coil the air is cooled and the water is heated q is positive. Size steam condensate size online calculator.
