Testing my ice chest air conditioner on a hot, humid day over a period of 7 hours.
Notes: The cooler was holding 35 lbs of ice ( 3- 10lb blocks, 5lbs of cubes) and one gallon of water. No freezer bags were used which would have extended ice melt duration.
The actual outdoor temperature in the shade according to my infrared thermometer was 105 degrees (temp sensor under intake grill was in direct sun for a period, indicating 111). Humidity was 70% average.
The cooler was not moved or opened during the test. The camera was removed from the tripod and brought inside between takes.
