An engineer wishes to select a suction line that will have a maximum pressure drop which is equivalent to a 2°F saturation temperature drop. What would be the pressure drop for a 134a system operating with a 0°F saturation temperature?
What will be an ideal response?
134a at 0°F saturation is 6.5 psig. 134a at -2°F saturation is 5.5 psig 6.5 – 5.5 = 1 psi drop for a 2°F saturation temperature drop
