Certified Air Conditioning Cooling Capacity Test
The heat removal capacity of the room air conditioner is based upon tests made in accordance with American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) test conditions. The test conditions are as follows:
Outside Air Temperature
95° F. D. B. (Dry bulb) 75° F. W. B. (Wet bulb)
Inside Air Temperature
80° F. D. B. (Dry Bulb) 67° F. W. B. (Wet bulb)
The approximate rate of moisture extraction for a typical air conditioning model under the above test conditions may be nine pints (approximately nine pounds) per hour.
Note: This quantity of water, removed from the air, represents approximately 9,000 British thermal units/hour (Btu's/hr) of cooling capacity.
Therefore, for a air conditioning unit rated 30,000 Btu's/hr, the difference between 30,000 and 9,000 leaves approximately 21,000 Btu's/hr for sensible reduction of the air temperature. Each pound of water removed from the air represented a latent heat load of approximately 1,000 Btu's.
Sources of Heat Gain
Sensible Heat. Sensible heat is that portion of the heat load that causes a sensible elevation or lowering of temperature that can be read on a common dry bulb thermometer. For instance, if we lower the temperature of a room from 85° F. to 80° F., we must remove sensible heat.
Latent Heat. Latent heat is that portion of the heat load represented by water vapor present in the air. It is possible to add water vapor to the air or, conversely, to take water vapor away from the air without changing the temperature of the air. A dehumidifier installed in a basement will remove moisture without reducing the base temperature. Roughly, 1,000 Btu's of heat per pound of water is required to make the physical change in water from liquid state to vapor state. Conversely, every pound of water that the air conditioning temperature of the outlet air that is discharged through the discharge louvers.
1. Suspend a thermometer in the stream of air entering the air conditioning evaporator coil.
2. Suspend another thermometer in the cold stream of air that is discharged from the air conditioning evaporator.
3. Operate the air conditioner for 15 minutes with controls set for maximum cooling. Close fresh air vents (if used) and put the air conditioning thermostat on its coldest setting.
4. Obtain temperature differential (TD) by subtracting inlet air temperature from discharge air temperature.
5. Compare temperature differential (TD) of unit under test with the TD shown in the applicable performance chart for the air conditioning model being tested.
An air conditioner that produces a temperature differential of 15 degrees to 20 degrees under average conditions is considered to be degree properly. In extreme humid weather, a temperature differential of 10 degrees would be considered adequate, due to the loss of air conditioning cooling capacity in dehumidifying the air.
