| Abstract |
During the last decade, an increasing interest in district heating system has emerged. In this paper, the physical measurements and data monitoring by internet were carried out with regard to heating energy consumption at the three apartment housings with district heating system in Ilsan district, Korea. Measurements were made of the thermal factors such as the pressure of heating pipe, flow rates, hot water temperature and etc. The purpose of this paper is to evaluate comprehensively the effect of variable outdoor temperature upon the heating load pattern in apartment housings with district heating system in order to develope the design criteria of this system and to understand the heating energy consumption pattern of user. Furthermore, the paper sets up the database of heating energy consumption in order to forecast the heating energy demand of apartment housings. As the result of the study, it can be seen that average heating load per unit area decrease to the rate of 7.1% according to the rise of 1℃ of the average outdoor temperature. Thus, it suggests the basic data for assessing the design criteria of heating energy consumption based on the field measurements and survey in district heating system. |
