Cogeneration In Residential Areas With Hot Summer And Cold Winter Study On The Application Of Heating(Cooling)

Cogeneration technology is an important development direction of energy technology in the world,which has the characteristics of high energy comprehensive utilization efficiency,small impact on the ecological environment,reliable supply guarantee and good economic and social benefits.In recent years,energy departments at home and abroad have issued a series of relevant policies and implementation opinions,and actively encouraged the use of thermal power plants to provide heat medium(steam,hot water)for centralized cooling in public buildings and conditional residential areas,so as to improve the annual average thermal efficiency of thermal power plants,reduce the proportion of air-conditioning in the power load,improve the comprehensive utilization efficiency of energy,and improve the environment at the same time Benefits and social benefits.With the improvement of living standards,people’s requirements for the quality of life and indoor comfort are also increasing.Due to the difference of building envelope in hot summer and cold winter areas,plus the weak awareness of energy conservation in this area,at the same time,the relative humidity of air in hot summer and cold winter areas is high,the indoor environment is poor,and the comfort is greatly reduced.The climate characteristics of hot summer and cold winter areas and the thermal insulation performance of building envelope should be taken into account in the system design.In the design of air conditioning system,the mode with high energy comprehensive utilization efficiency should be selected in combination with the local resource advantages.In this paper,the advanced experience of cogeneration technology in the central heating(cooling)residential system at home and abroad is investigated and summarized.Combined with the development of cogeneration in Hefei,the central heating(cooling)residential system in a residential area is selected as the model.From design to operation,the data is tracked and analyzed.Combined with the operation of the pipe network,the heat loss in heating and cooling seasons is analyzed Combined with the economic analysis of the cogeneration central heating system and the traditional electric air conditioning system,it is proposed to promote the use of residential district central heating(cooling)residential system,improve the economic operation of the pipe network,reduce the heat loss of the pipe network,improve theeconomic and environmental protection benefits,and promote the health of the urban cogeneration cause in the hot summer and cold winter areas covered by the cogeneration,and in the areas where there is a demand for hot and cold At the same time,improve the living environment in hot summer and cold winter areas,and improve the quality of life of residents...
