대형역사 난방에너지 절감방안에 관한 연구(제1보)

In this research, we had survey and examination to know about problems of management and selection of HVAC system of S station which has high consumption. So we suggest improvement plan. Results of this study are as follows. (1) As the heating system is longer, temperature difference is higher, So stratification appear strongly. As we stop heating, the effect is less. (2) We consider that bad heating condition is due to infiltration air of frequent opening and shutting. So the measure of this problem is urgently needed. (3) According to TAB measurement of S station, AHU generally shows its ability just 50% compared with design of air flow rate. So it needs check and adjustment. (4) With thermal environment and TAB result, we prepared architectural improvement such as a restraint of infiltration through improvement of vestiblue and restraint of filtration with Airtight ability increase of smoke elimination fan and arrangement improvement such as restraint of stratification through circulation and improvement of HVAC system.
