Location

South Central U.S.

Equipment

30-Ton Carrier Air Conditioning Unit (electric)

Conditions

Mid-summer, however the unit was only operating at one-third of its 30-ton capacity during the test. This does not harm the test; it only results in lower savings than could be achieved at full load.

Savings

Extrapolating the energy savings from the test period to a full year’s operations and using the recorded data values, the energy savings would be 18,718 kWh. At an average energy cost of $0.155/kWh, this would be an annualized savings of $2,901/year.
