공동주택 단지 연간 배관 열손실 계산 기법에 관한 연구

In recent, the energy efficient technology are newly evaluated as for very effective countermeasures against global climate change and carbon trading issues. In the field of building energy, the reduction of heat loss so as to deliver more produced energy to the customer becomes one of the crucial topics in terms of energy saving and economy. In this study, the effective calculation method in 1-D simulation of heat loss for an apartment housing is assessed. Especially the simple but effective correlation between the heat consumption by user and the ambient temperature is derived based on the annual measurement data. The proposed correlations has been verified using 1-D simulation tool, FLOWMASTER, for a test case of the apartment. The results with the newly proposed simple correlation between heat consumption and the ambient temperature shows a good agreement with those of conventional simulation procedure with substantial data input by daily operation.
