| In recent years,environmental pollution is getting worse and worse,the energy shortage is becoming more and more serious.In the total energy consumption,the proportion of building energy consumption is more and more big.The national vigorously promote coal to electricity,coal gas clean energy heating imperative,full consideration based on the above,proposed the use of air source heat pump and solar heating way,so as to alleviate the increasingly serious haze weather and energy shortage problem.This paper first to do their internship,a district of Qinhuangdao City,air source heat pump heating renovation project as an example,detailed description and introduces the composition of air source heat pump heating system,the design of a complete set of air source heat pump heating system and control system of operation monitoring data in real time through the analysis of the heating of wisdom,the overall energy efficiency of the whole system,the operation cost and the actual heating unit than COP and made a detailed comparison of traditional energy and heating,the application of air source heat pump in winter heating in northern China has great advantage of energy saving.Then based on the application of air source heat pump heating,combined with solar energy combined heating system in Qinhuangdao Development Zone and a 198m2 small villa as an example,through theoretical analysis and calculation of the operation mode of the combined heating system of solar collector area,collector installation position,the hot water storage tank and a circulating water pump the size,joint system and automatic control principle,analyzes the advantages of the combined heating system.At the end of the combined heating system was evaluated,including: economic efficiency,energy efficiency and environmental benefits,the traditional energy and heating compared with certain economic advantages,combined heating system and environmental protection benefits,has certain market competitiveness. |
