| Energy resources are the reliable and indispensable element for human being. As the increasing consumption of the energy resources,the whole world is lack of it. The mineral fuel is decreasing,while the energy supply is much less than the actual needed.In the future,according to a literature,a key element for our country to maintain the rapid development is the abundance of energy resources.Therefore,the problem of the energy resources is becoming the issue which will affect the future of our country.However,as the rapid development of our country,the scale of the constructional industry is expanding,as the energy that consumed in the constructional industry is increasing.The air conditioner and the hot water supplying system consume a large amount of energy.But the air conditioner and the water heater are exchanging the same energy from the high-order energy to the low-order energy.That is not compliant with the principle of saving energy.So,the excess heat from the air conditioner is becoming more important and more people begin to study on it.From this article,by calculating the energy consumption in the air conditioner system and the hot water supplying system separately in Xian Tao NO.1 Hospital, the writer educes the conclusion as follows:(1)By analyzing the waste and pollution problems that caused by the hot water supplying system and the air conditioner system,present the idea that combine the two system into one system.That means using the excess heat from the air conditioners to making hot water.(2)By analyzing the ability of the centrifugal refrigerating system and the helical refrigerating system in academic state,find out that the usable energy is only a little high temperature of gaseity sensible heat,but it is enough for the ordinary use.(3)By analyzing the economy benefit of the excess heat from the air conditioner,find out that the function charge can save a large amount of money than the ordinary system.The added heat exchange makes the added charge of early invest.(4)By using the fuzzy mathematic theory,the writer estimates the system from economic guide line, technical guide line and the environmental guide line,the result shows the system is excellent,it shall be extended and widely used. |
