| The new environment-protection solar heating water supply system is a kind of collector solar heating water supply system that has motive-circulating equipments and keeps the equipments of water in the lowest place.The main characteristics in this system is to use motive-circulation equipments to keep the press of each point in the water which can resolve the phenomenon of the cold and heating asymmetry inside each point in the water of the natural circulation and can improve the problem of wasting lots of water. The area of concentrating heating water supply is not limited after increasing the motive equipments. Motive equipments are always circulating before the temperature arrives the given values. It not only increases the comfort but also save water (every time that nature circulation usage needs to put a flood of water) furthermore this engineering design places water pitcher in the ground floor and resolves the problem of over big house's partly-carry and easy jelly etc. This paper takes the example of collector solar heating water supply engineering in China-Japan union hospital medicine hospital of Jilin University for research object, proceeds the system-science design and application study.Traditional concentration heating water supply includes various forms. In regard to making heating that take heating water lie quality, it mostly consuming nonrenewable energy for price, such as the coal (oil, gas) boiler proceed heating water supply direct or indirect; In regard to the circulating way of the heating water: it has the nature circulation and the motive circulation and the top position or bottom position of water supply main tube and also has the different position of establishing circulation tube (namely half circulation, whole circulation). Regardless any supply it has benefit and fault of its own. The problem that the design of system aims at is: How to solve the nonrenewable energy? Which energy can take place of it? How to solve nature circulation pressure asymmetry? How to solve the freeze of the solar water tanks that have been established in the tallest place? This paper does the research on these four problems.Along with the nature resources used up on the earth such as coal, oil, gas etc, the energy crisis aggravates increasingly, the crisis of the environment pollution threats the ecosystem equilibrium, so the research to develop the solar energy has come with us.Solar energy being non-pollution energy, it is best taking the place of the non-renewable energy. Because the solar energy can't cause greenhouse effect and change the global climate like the fossil fuels such as petroleum and coal. Solar energy is not only one-time energy, but also renewable energy. Its resources are abundant, and have no pollution to the environment. Expanding the solar technique strongly has the important meaning for improving the whole environment on earth.There has new environment protection energy that is can renewable thus it must have the better collector solar heating water supply to match it.The collector solar heating water supply that there has been is to put the water tanks in the tallest place and most is nature circulation. To the existent problem, during the design and research, the system is established the motive circulate equipment and put the water tanks in the lowest place. At the same time we study some technique guarantee measures. For example establishing 3 water pitchers to guarantee the temperature of heating water supplies, at the inlet of circulate equipment establishing some press-stable device and establishing the decompression equipment in the outlet to ensure the pressure stability for system working normally and this paper also considers the emergency that when solar energy is not enough the heating water can be supplied etc.This paper proceeds the thorough technique analysis to collector solar heating water supply system on the expenses of running, beginning investment, service life and environment protection. Conclusion is: the new environment protect...
