So, want to measure the air leakage this way? Less leakage helps with AC,
no matter what the system.
1. Run a dehumidifier indoors for a few days with the cabin windows and doors
closed, to remove moisture stored in indoor surfaces.
2. Empty it, and measure the indoor and outdoor temps and RHs over 12 hours.
3. Measure how much condensation it collects.
4. Calculate the cabin air leakage as above:
Pao = RHo/100e^(17.863-9621/(460+To)) = 0.887 "Hg.
wo = 0.62198/(29.921/Pao-1) = 0.0154.
Pai = RHi/100e^(17.863-9621/(460+Ti)) = 0.524 "Hg.
wi = 0.62198/(29.921/Pai-1) = 0.0111.
cfm = 0.0185N/(wo-wi) = 30.
5. If cfm > 30, find and fix water leaks, caulk, airseal, and so on...

One does wonder, is this information anything like that for bilge pumps?
