Regional Heat Pump Energy-saving Optimization Of Energy System Analysis

Since the reform and opening up,with the rapid development of China's economy,the process of urbanization has been greatly promoted,and the development Since the reform and opening up,with the rapid development of China's economy,the process of urbanization has been greatly promoted,and the development of regional energy has become more and more concerned.In this paper,the advantages of regional energy and ground source heat pump,combined with the construction of the regional heat pump energy system.Therefore,the regional heat pump energy system as a combination of GSHP and regional energy system,which has high rate,can effectively improve the regional building thermal environment,be friendly to environment and renewable energy utilization,but also with ice cold storage combined with the advantages of peak and reduce the operation cost,and has broad application prospects.Regional heat pump system consists of three parts: energy station,pipeline network and users.The three part is a waste of energy and unreasonable place.To optimize the regional heat pump energy system,and to play the advantages of regional energy and ground source heat pump,therefore,this paper makes a comprehensive analysis of the regional cooling system.The first part,pipeline system on energy consumption effects of pipe diameter,pump energy consumption,the thickness of the insulation layer of the analysis,further optimization of the influence factors of online transmission pipe,reduce the waste of energy.Finally,the reasonable function radius of the regional heat pump energy system is given,which makes it more energy saving compared with the traditional heating system of the boiler room.The second part,the heat load region by building air conditioning based on energy consumption model of heat pump,heat pump unit according to the reasonable selection of energy consumption model,optimize the use of technical economics knowledge of different configuration of the heat pump unit combination.The third part,combined with the regional central heat pump system of Guan Tao County,carries on the example optimization,provides the reference and the reference for other district heat pump energy system's optimization application.In the fourth part,based on the calculation model of the initial investment and the annual operation cost of the heatpump system,the economic comparison between the regional heat pump system and the single building heat pump system is carried out.And the impact of regional heat pump energy system of government policy guidance and subsidy incentives,as well as electricity prices in two aspects of research and analysis.Finally,a summary of the main content,through the regional heat pump energy system with dispersion type single building heat pump system in energy efficiency and economy of the traditional boiler heating system,heat pump system,reflect the regional advantages of energy.The deficiency of this paper and the direction of further research are put forward.
