주거건물의 개별급탕방식 환탕배관 적용에 관한 실험적 연구 = An Experimental Study on the Application Plan of Recirculation System for Individual Hot Water Supply System in High-rise Residential Buildings

다국어 초록 (Multilingual Abstract)

In the current residential building, hot water supply system consumes the second largest energy in order to make the thermal comport condition of residential space. The more residential environment improves the more the demand for hot water and water consumption is increasing gradually. So this study examines the possibility of applying the recirculation for individual hot water supply system compared with the existing method for waiting time for hot water, wasted water and energy consumption. The results are as follows. (1) In case of recirculation system method the waiting time for hot water can be reduced up to 69～85% in spring and fall period and so dose up to 77～85% in winter period. (2) The total wasted water has a little change compared with the existing method which can make the total wasted water reduced about 77～86%. (3) The efficiency of hot water supply system can be improved, if the method which blocks the inflow of cold water is applied, when return pump is operated to recirculate hot water in recirculation system.
