The above shows a sea level calculation.
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.
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.
Coil programs use actual conditions.
Includes 53 different calculations.
Online calculator to quickly determine pipe sizing by velocity for water.
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.

The chilled water circulates through a chilled water loop and through coils located in air handlers.
However this guide focuses.
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.
Chilled water systems include other hvac equipment designed to exchange heat such as computer room air conditioners.
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.
Hvac chilled water system pipe sizing excel calculator for free.
Pb altitude is calculated from the.
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 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.
The chilled water pump is used to circulate chilled water in a closed system.
Properly sizing a chiller for your application can depend on a large number of variables.
