A distribution model is developed for relative humidity, and additional relationships are presented that allow the distribution model to be used on an hourly basis with either monthly-average daily relative humidity or monthly-average daily dry-bulb temperature and clearness index as the only meterorological data input. A procedure is described that allows the estimation of two-dimensional dry-bulb temperature/humidity ratio bin data from the distribution models for dry-bulb temperature and relative humidity. Comparisons of measured and estimated dry-bulb temperature/humidity ration bin data are presented. A design method for the cooling load on a residential air conditioner is described, and air conditioning loads are calculated using both measured and estimated dry-bulb temperature/humidity ration bin data.
