If the condenser pressure of the above system is 317 psig, how much subcooling will be required to offset the pressure drop created by the vertical lift?
What will be an ideal response?
317 – 13 = 304 psig. Total subcooling is calculated by determining the saturation temperature of 317 psig R410a that is approximately 100°
and the saturation temperature of R410a at 304 psig, which is approximately 97°F. 4°F of subcooling will be required to prevent flash gas. 100°F – 97° = 3°F + 1°F = 4°F
