Abstract |
Recently, an increasing interest in district heating system has emerged rapidly. In this paper, the physical measurements and data to be monitoring through the internet were carried out with regard to hot water heating energy consumption at the three apartment housings with district heating system in Sang-am district of Seoul, Korea. Measurements were made of the thermal factors such as the pressure of heating pipe, flow rates, hot water temperature and etc. The objective of this study is to compare the design capacity of reheat exchanger with that of preheat exchanger in order to evaluate for the number of plates of two exchangers to be distributed properly. |
