Hi All In CHW system, EWT/LWT CHW temp for AHU are 5&12 degC Room setpoint shall be 22 degC & return = 23 degC Total supply air, say 4000 L/s?

In such case what's ideal supply air temp & how is it calculated considering heat transfer between CHW & supply air?  What parameters can be controlled to vary supply air temp & what's the range of supply air temp that can be achieved for above scenario?

Normally the supply air temperature is kep 14-15 Deg C.

The formula for sensible load is

Sensible heat = (mass of the body) * (specific heat capacity) * (change of the temperature)

 

You can derive what ever the value you need from this equation

Hope this will be fine
