| 요약2 | In this study, a bypass heating system was suggested to improve the part load efficiency of individual room control for residential heating systems. TRNSYS simulation model for the suggested system was developed and heating energy consumption was analyzed to examine the practical applicability. The system was represented with 3-way valves, small circulation pump, and electric heater, which operates under part load condition that water temperature difference becomes less than 10℃. Simulation results showed that the heating energy consumption was reduced by 60% under the aforementioned part load condition. During the whole heating season, the bypass heating system operated for 342 hours, while the operation time of the boiler was reduced by 19.6%. Consequently, heating and pumping energy was reduced by 4.02% and 15.1%, respectively, which resulted in the overall energy saving by 4.12%. |
