At the driver's seat, temperatures were 78.8F with AAC, compared to 92.1F with refrigerant a/c, that's 13F degrees cooler for drivers.

*Note 1-VehiCool AAC system achieved more cooling in 5 minutes than the refrigerant system produced in 45 minutes.
*Note 2 -VehiCool system reduced interior temperature by 30F and held temperature near the center of the human comfort zone.

This test is typical of many formal cooling comparison tests conducted between VehiCool Adiabatic Air Conditioning and refrigerant air conditioning systems. In addition to the actual recorded temperature difference, observers agree that the higher air flow of AAC systems enhance the sensation comfort - passengers can "feel" the air movement.

In areas of higher humidity, the interior AAC temperature will rise by about 1F degree with each 1F degree rise in wet bulb temperature (wbt).

In hotter conditions, the interior AAC temperature will rise by about 1F degree with each 5F degree rise in outdoor dry bulb temperature (dbt).

Yet even these effects are mitigated by the greater cooling sensation  resulting from the higher air flow rates of AAC systems.
