Chilled Water Coil Sizing Calculator

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.

Chilled water coil sizing calculator. Pb altitude is calculated from the. This guide covers the design and selection of a chilled water pump. In a chilled water coil the air is cooled and the water is heated q is positive. 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.

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. Size steam supply pipe online calculator. Size steam condensate size online calculator.

At 100 db and 78 wb the w 015601 lbw lba density 06914 ft lba. Qwater 500 gpm leaving water temperature entering water temperature. The same equations apply for altitude however the true density must include db wb and pb altitude pb. Online calculator to quickly determine pipe sizing by velocity for water.

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 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. It is a balance between the desired capacity and the resultant 20.

For over 40 years our team at cold shot chillers have successfully sized quoted and built machines for many applications. However this guide focuses. Hvac chilled water system pipe sizing excel calculator for free. Properly sizing a chiller for your application can depend on a large number of variables.

1 1 units there are two calculators 1 one that focuses on united states customary system units uscs and another on 2 international system of units si. Flash steam per cent online calculator. The chilled water absorbs the heat from the building. 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.

Chilled water systems include other hvac equipment designed to exchange heat such as computer room air conditioners. The above shows a sea level calculation. The chilled water circulates through a chilled water loop and through coils located in air handlers. Equations displayed for easy reference.

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.
