Current water distribution systems like branch type and separate type piping systems have still had some limitation with instability for temperature and flow rate when using multi water-taps simultaneously in a house and waste of water resources when using hot water. To improve these problems, we have developed a water-saving hot water piping system using thermo valve. The present study was undertaken in order to evaluate performance of the improved system compared with the existing system. The results show that our system restrains a waste of water and we can immediately use water at set temperature after 78~87 sec circulation. Also, in cases of using multi water-taps, average temperature deviation was below 0.6℃ and decrement of flow rate reduced over double. And The economics of the existing Separate type piping system and Water-saving hot water piping system were compared & analyzed. So The cost savings of Water-saving hot water piping system were identified. |
