The annual hours of air-conditioning compressor operation are calculated for two types of use:(1) a house that is naturally ventilated to temperatures between 75 and 78°F when the outdoor temperature and wind speed will permit, and air conditioned at 78°F when required, and (2) a house that remains closed-up and is air conditioned at 78°F. For the 10 cities investigated, compressor savings from natural ventilation ranged from 12％ in Phoenix to 73％ in San Diego. These results are generalized to estimate the compressor-operating hours for any U.S. location. Potential purchasers of air conditioners can use this information to estimate their operating costs.
