Hi All, i have struck up with some queries!!!
can anybody help me out for calculating the TR of an unit, by taking superheat and subcooling temperature...is there any formula for it or is there any calculator for this

And as we are using R410a refrigerant for the first time, i also would like to know the superheat and subcooling range of temperature for it, and its Low pressure(LP) and high pressure(HP) recommended.

hi if u are trying tu calculate how much tonnage u are getting out of your unit this is the correct and easy calculation
delta t *1.8 *500*GPM divided by 12000= TR:D
