Sir, is there 4005 constant at every calculation???

[@ZAFARKHAN-eb4wl]

What is 4005 and where did this come from?

[@SandeepVShaji]

[@gautamshivraj3782]

4005 kaha se aaya

[@miteshzala5400]

Sir I have one question
Inside of AHU two coils are available one is CHW coil and other is HW coil
When we find heat load and find TR
So this TR is only for CHW coil tonage so what about HW coil TR is there is same or not

[@bhagyeshcharpe2925]

This is not same..we have to do calculation for that and calculate heating requirements saperatly
