Ive worked out a cooling load for two Chiller rooms
The first one , the duty required is 4.32 Kw
The second is 6.29 Kw

What is the correct way to to size the condensing unit and evaporator coil using the wholesalers charts.

This has always been a grey area for me, and Im determined to get it right and learn the proper way to do it.

The third question is, how to I accurately select the orifice for the expansion valve

Thank you in advance
