Hi,
I have an project to design evaporative condenser.Design Conditions are:
Fluid:R404A
Condensing temp.:38 C
Wet Bulb Temp:26 C
Requested Capacity:210 Kw
Tube :26,9mmx2,6mm thickness of galvanised carbon steel
Can you help me about the sizing of the coils?

You would normally use circulating water in an evaporative condenser, with a shell and tube or plate heat exchanger on the chiller.
