Abstract
Air-conditioning load takes 30% among the total electricity consumption of a building. It is important to know the electricity consumptions for air-conditioning in detail to each building. However, it is difficult to measure the consumptions of the existing building directly. This report proposed the estimation model for the power consumption of air conditioning. The model uses two hourly data which are user's total electricity consumptions and the ambient temperatures. The hourly electricity consumptions are divided to the air conditioning and the others consumption. The model is written by MINLP, but is easily computed by practical conversion. In the case study, the 13 user's hourly consumptions were estimated. And one of 13 users was compared with the measured consumption for air conditioning. Its coefficient of determination (R2) was 0.84. It means this model is useful for estimating the electricity consumption of the air conditioning.
