Segregated residential air conditioner load model behavior with temperature and humidity

In particular, in hot and humid summers, an important proportion of the overall electric power is dedicated to satisfy air conditioner loads. Outdoor weather conditions are crucial in determining residential energy consumption for heating, ventilation and air-conditioning (HVAC) household appliances. In this paper we address the modeling of outdoor weather conditions impact on predominantly air conditioner residential load. The main emphasis is on the temperature and humidity segregated load influence where the socioeconomic and life style of the consumer is isolated from the load model. Important field data has been collected for several hot and humid consecutive months covering a wide range of outdoor temperature and humidity. After recognizing that humidity can be divided into three different comfort levels, three-dimension analysis of the data have been conducted and mathematical relations have been extracted to represent the dependencies of the real power with both humidity and temperature. The investigations have shown the sensitivity of the load to temperature and humidity to be in good compliance with the expected natural load behavior.
