본 연구에서는 온수순환시 스템에 최적화된 가변유량 밸런싱밸브(variable-flow-rate balancing valve)를 개발하고, 현재 사용되고 있는 시스템 분배기에 장착하여 그 성능을 평가하고자 한다. |
| 요약2 |
A variable-flow-rate balancing valve has been developed and optimized to apply to a distributor in a hot-water heating system. Fluid dynamic performance of the system was evaluated by comparing the results with the previous pressure difference control valve (PDCV) system. In view of the variations of pressure drop and flow rate according to the sequential closing of the control valves, the present system which is named “smart system distributor”, is very stable without a certain flow rate concentration. The level of pressure drop variation is also low as compared with the previous system with a PDCV. In view of the occurrence of cavitation, the present system is quite superior to the previous system because the instantaneous pressures at all sections are much higher than the vapor pressure. On the other hand, the previous system has a possibility of cavitation when one or more control valves are closed. |
