| 요약2 | This study analyzed the characteristics of the variable flow system of the secondary pumps in the heating/cooling system of apartments by control method and selected a control method which can be applied to new building construction and existing building remodeling. The system applicability was reviewed on the selected control method by using the piping network analysis program Flowmaster V7 and the system performance was examined by comparing the energy consumption of the variable flow system to the energy consumption of a fixed flow system. The result of the study shows the following. At the valve open rate of 0.2ratio and the differential pressure target value of 1.0bar, the energy saving rate was 84.51% (5.73kW). The saving rate was 72.86% (4.94kW) at 1.5bar, 59.44% (4.03kW) at 2.0bar and 43.66% (2.96kW) at 2.5bar. At the valve open rate of 0.4ratio and the differential pressure target value of 1.0bar, the energy saving rate was 80.20% (8.18kW). The saving rate was 63.04% (6.43kW) at 1.5bar, 46.08% (4.70kW) at 2.0bar and 25.00% (2.55kW) at 2.5bar. At the valve open rate of 0.6ratio and the differential pressure target value of 1.0bar, the energy saving rate was 68.35% (6.89kW). The saving rate was 43.15% (4.35kW) at 1.5bar, 46.08% (4.70kW) at 2.0bar and 17.36% (1.75kW) at 2.5bar. |
