Background technology
Circulation hot-water system can coordinate a variety of water heaters such as gas heater, positive displacement, Instant heating type, solar energy, air energy
Use, have return pipe and can be installed without return pipe.As some home-use hot water pipelines are longer(Water heater is apart from hot water tap
It is longer), every time using hot water when need to wait good long a period of time, or the unified high-grade hotel supplied water and seek for 24 hours
Industry place, in order to allow customer to use hot water at any time, can set circulation hot-water system, it applies also for some demand temperature in addition
Constant water or circulation heating place, such as medicinal material are planted, and treasure the cultivation place of animal.
In recent years, with the continuous development of scientific technology, relevant industries were more next to the technical requirements of circulation hot-water system
It is higher, but also there is following defect in existing circulating hot water pipeline:
1st, after use after a while, its steel pipe inside and outside wall corrosion, wear is serious, and maintenance is complicated cumbersome, uses
Life-span is very short;
2nd, the temperature and flow control accuracy of water are low in pipeline, user water temperature and water-carrying capacity can not be monitored in real time and
Regulation;
3rd, heat insulation effect is general, and can scatter and disappear substantial amounts of heat energy in water cycle process, and serious waste of resources is with high costs.
