In calculating the pressure losses, or gains, note that each foot of rise in a liquid line results in an
approximate 0.5 psi loss. Thus a 10 foot rise represent 5 pounds per square inch loss in refrigerant
pressure, or the equivalent of 1.6ºF subcooling with R-22. Total line losses will include values for
line friction, equivalents for valves and elbows and pressure losses from manufacturers’ catalogs for
driers, solenoids, sight glasses, etc.
When calculating condenser subcooling, note that saturated condensing pressure should be read at the
same point in the system where the liquid refrigerant temperature is obtained.
