Abstract
Monthly statistical weather data from stations around the world are compiled for periodical base heat load calculations. The source data are the publications by Meteorological Office (D1), the magnetic tape compiled by the Japan Meteorological Agency (D2), the literature on the world solar radiation distribution by the solar energy laboratory at the University of Wisconsin (D3), BIN solar radiation data by ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) (D4), and the solar radiation observations at Japan Weather Observatories (D5). The weather elements required for ordinary heat load calculation are air temperature, humidity, solar radiation, wind direction, wind velocity and cloud cover. Among these weather elements, D1 and D2 include air temperature and relative humidity, and D2 contains additional three elements; i.e., wind direction, wind velocity and cloud cover. Since both the stations in D1 and D2 lack in solar radiation data, they are supple-mented from those at the nearest stations in D3, D4 or D5. Wind direction, wind velocity and cloud cover for D1 stations are cited from those at the nearest stations in D2. As the result, the monthly weather data for heat load calculation are compiled at about 2400 and 2000 stations listed in D1 and D2, respectively. Excluding the overlapping stations in D1 and D2, more than 3700 stations all over the world are obtained. These data are recorded as the random files of a personal-computer. The approximate memory sizes of both D1 and D2 files are 1.1MB (mega-byte). The procedure for the estimation of daily variations of weather elements, and the method of the heat load calculation using personal-computer will be discussed in the following report.
