The material basis of human survival is energy,development is also inseparable from the continuous use of energy.But the fossil energy on Earth is limited,human beings have to face the growing shortage of energy status,which requires people in the process of continuous transformation of the world,the positive development and use of renewable energy to make human development can be continued.Although our country in the combination of solar energy and architecture has come to the forefront of the world,but many high-rise buildings did not take into account the convenience of the installation of solar energy,resulting in the difficulty of solar arrangements and roof collection area is limited and so on.This article first introduced the solar hot water system,and for the centralized collector sub-household heat storage system to give a project case,this case contains 32 buildings,the total area of the collector a total of 5686 square meters,each household has an average collector Area of 1.02 square meters.Explain in detail the case of the design principles,and each building solar guarantee rate,and the temperature of the winter were checked.The operating principle of the system is divided into four parts,which are described in detail,including the top part of the main components such as solar collectors and buffer tanks,including the standard layer of main components such as heat storage tanks and water points,including pressure reducing valves,Pressure gauge and other major components of the decompression part,including the underlying part of the underlying pump part of the principle.And the control process and operation principle of the whole solar hot water system are expounded.Secondly,this paper expounds the main characteristics of high-rise buildings,and focuses on the analysis of the main features of the low guarantee rate of solar energy.The value of the basic water temperature,each household 1.02 square meters of the average gathering area of the case,the average solar energy guarantee rate of 35%,less than the user's request.In this paper,17 samples were analyzed and the data were analyzed by Origin 8.0 software.The fitting curve of the origin was S1 =0.275S0 and the standard deviation was 0.0134.The paper also analyzes the relationship between solar energy assurance rates and other factors such as initial water temperature,time,insulation(heat loss rate),termination of water temperature.In addition,the article calculated the heating time of the auxiliary electric heating under different conditions,the maximum average heating time in January,the daily heating time of up to 2h;the minimum average heating time in June,the daily heating time For 0.33h.The amount of heating time reflects how much users use traditional energy.The smaller the heating time,the greater the proportion of solar energy supply,the better the effect;the contrary the worse the effect.Finally,this paper gives the application of solar hot water system in high-rise buildings should pay attention to the problem,it is recommended to consider the design of four modules,and solar applications in high-rise buildings on the prospects for the future.
