What you're not taking into consideration is the rate of temperature drop based on the starting space temperature and the
A/C evaporator coil temperature. The greater the differential, the quicker the curve on the cooling. As the return temperature drops to the coil temperature of approx. 40 degrees you'll see a slower temperature fall. You also didnt include the starting humidity which would slow the rate of temperature drop for each house. Were you comparing the same SEER unit?
Watch again. The starting conditions are the same. 40 degrees? You must mean the heat-exchanger temp. Compressor coils get 135 degrees and EvAAC only cools 20-30 degrees. Ive recorded return air at 55 degrees. The test house - SEER 14, the baseline house - SEER 12. EvAAC is more important that SEER. SEER design and testing is done at 95 degrees and the hotter it gets the greater loss in efficiency. A SEER 12 drops to 8 at 110 degrees. The point is; a 60% reduction is HUGE. PERIOD.
