Question

question 2
410a refrigerant
low side pressure 97 psig
high side pressure 317.1 psig
suction line temperature 48 degrees f
liquid line temp 98 degrees f
what is the subcooling? (number only, no units)

Explanation:

Step1: Recall subcooling formula

Subcooling = Liquid Line Temperature - Saturation Temperature corresponding to high - side pressure. For R - 410A, the saturation temperature corresponding to 317.1 psig is approximately \( 100^{\circ}F\) (from R - 410A pressure - temperature chart).

Step2: Calculate subcooling

Subcooling=\(98 - 100\)

Answer:

\(2\)
