Among many outdoor conditions which are the basis for studying the air conditions in occupied rooms, outdoor air temperature and solar radiation are very important factors for estimating air conditioning load. We, at first, investigated their states of periodic variations at Tokyo, Osaka and Sapporo by the statistical treatment of many data obtained from meteorological observatories during 40 years. Generally, the estimation of heating and cooling load has been made with the assumption of the steady state of outdoor air so far, but such method of calculation is too rough to estimate the cooling load. We used the result of the analysis of meteorological factors above mentioned and tried to get the precise solution of the cooling load based on the periodic variation of air temperature. Then, we found that the precise solution has less errors than the other method which was derived from the assumption of the steady state. Since the calculations of precise solution are very complicated, some simplification by means of adequate diagrams may be required.
