Technical And Economic Analysis Of Thermal Storage Air Conditioning System

Thermal storage air-conditioning is one of the main measures to realize the "shifting peaks and filling valleys" of power equipment,and it is also the main trend of future air-conditioning development.In order to further optimize the thermal storage air-conditioning technology,its technical and economic analysis and demonstration are crucial.Starting from the basic theory of thermal storage air conditioning,this paper studies the design method of thermal storage air conditioning options.To carry out a reasonable air conditioning design for a building,it is necessary to conduct a technical analysis of the entire system in order to make a reasonable choice of various options.Taking the Qinxing Palace Museum in Qinhuangdao City as an example,the thermal storage air conditioning system and the direct heating air conditioning system were selected and designed,technical analysis was carried out for the engineering example,the heat load of the building was calculated,and the chart was sorted,and the thermal storage type was calculated according to the load.Air-conditioning system and direct-heating air-conditioning system equipment selection and calculation,through the selection of heat storage time of electric boiler heat storage system and load rate under different operation strategies,the initial investment and annual operation of heat storage system and direct heating system are calculated respectively cost.After discussing the economic evaluation of the air-conditioning system,from the economic point of view,the evaluation methods usually used for the air-conditioning system include static and dynamic evaluation methods.The static investment payback period and the dynamic investment payback period are respectively used to calculate the investment payback period.Finally,the mathematical model of the matrix was established by the analytic hierarchy process,and the evaluation indicators were comprehensively analyzed.Finally,the thermal storage system was selected as the optimal solution.In the end,the factors affecting the project payback period are the local peak-to-valley price ratio and the choice of heat storage time.In the future,as local governments successively introduce preferential peak-to-valley price policies,the energy storage air conditioner can fully achieve peak reduction.The value of filling the valley.This article has a certain reference significance for the design and demonstration of thermal storage air-conditioning projects.
