Abstract
We researched and analyzed the yearly, monthly, and hourly hot-water consumption at many apartment houses with district heating system to obtain engineering data. First, we analyzed the yearly hot-water consumption in comparison with the number of persons in a family (Fig. 4) and yearly income (Fig. 5). Next, we analyzed the correlation between the average montly hot-water consumption of 84 houses and the city water temperature (Fig. 6). Finally, we analyzed the hourly consumption patterns of 1〜40 houses in comparison with the city water temperature to obtain basic data for plant design. 1) Fig. 8 shows the hourly consumption patterns of 40 houses. 2) Fig. 16 shows how the peak load changes with the city water temperature and number of houses. 3) Fig. 22 shows the necessary capacity of the heat source equipment and storage tank for 1, 10, and 40 houses for city water temperatures of 5〜10℃.
