Abstract
To make proper application of energy conservation techniques in designing air-conditioning systems, it is required to estimate the amounts of the effects of many energy conservation techniques in each phases of air-conditioning system. This estimation holds so much amounts of computation that it is impossible without making use of computer system. Moreover, to make use of this estimation as a tool of routine work in design process, it is necessary that the estimation method not only retains a sufficient accuracy but also terminates in a limited computer execution time. We, authors, studied a simplified method of thermal load calculation which constructs the first step of energy consumption analysis. In this method, first, we arranged weather data of year-round every days to a few days for a month by means of the multivariate analysis method. And then calculate year-round heating/cooling load by means of daily periodic stational rule by month. This paper reports about this simplified method and its verifications.
