The Research Of Two-Source Heating System

This paper starts with resolving air-pollution in big cities in our country. And then it illuminates the importance and possibility of changing constitute of fuel for decreasing air-pollution. But the cost of high-quality fuel is so high that it is not accepted by most of people at present. So we must improve the efficiency of heating system and reduce the cost of fuel consumption. This paper analyses the thermodynamic principle of heating-pump heating system and cogeneration system, and then classifies them to reversible style heating system. But heating-pump heating system and cogeneration system have some disadvantages and their practical usages are not broad and effective. So this paper promote a new-style heating system ??two-source heating system ,which own the advantages of both heating-pump heating system and cogeneration system. This paper analyses the security, reliability, thermodynamic and techno-economic characteristics of two-Source heating system. It is very useful for future application.
