Hi All,

I'm new to learn and gain knowledge in this industry and currently facing a problem regarding the calculation part for refrigerant's superheat and sub cooling,

I searched few ways to calculate but answers that I get is different.

As other website suggested, I get these information to calculate superheat and sub cooling:

Suction Line Temperature: 4'C/39.2'F
Suction Line Pressure: 32psi / 17.30psig

Liquid Line Temperature: 41.5'C/106.7'F
Liquid Line Pressure: 230psi / 215.30psig

Indoor Temperature: 3.5'C/38.3'F
Outdoor Temperature: 27'C/80.6'F

Additionally, is superheat and sub cooling can indicate us the way to control humidity (RH%) in the cleanroom? Because current RH in cleanroom is excess that the RH required.

Thanks...
