Question

410a refrigerant
low side pressure118.3 psig
high side pressure 445.8 psig
suction line temperature 50 degrees f
liquid line temp 120 degrees f
what is the superheat? ( give numbers only, no units)

Explanation:

Step1: Find saturation temperature

For R - 410A refrigerant, using pressure - temperature relationship. From R - 410A pressure - temperature chart, for low - side pressure of 118.3 psig, the saturation temperature \(T_{sat}\) is approximately 40 degrees F.

Step2: Calculate superheat

The formula for superheat is \(SH=T_{suction}-T_{sat}\). Given \(T_{suction} = 50\) degrees F and \(T_{sat}=40\) degrees F.
\(SH = 50 - 40\)
