Chilled water coil sizing calculator.

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. In a chilled water coil the air is cooled and the water is heated q is positive. Coil programs use actual conditions. Size steam condensate size online calculator.

Flash steam per cent online calculator. 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 same equations apply for altitude however the true density must include db wb and pb altitude pb. This guide covers the design and selection of a chilled water pump.

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. Chilled water systems include other hvac equipment designed to exchange heat such as computer room air conditioners. 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. 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.

For over 40 years our team at cold shot chillers have successfully sized quoted and built machines for many applications. The chilled water circulates through a chilled water loop and through coils located in air handlers. It is a balance between the desired capacity and the resultant 20. At 57 50 db and 57 30 wb the w 0099622 lbw lba.
