Application And Research On Solar Energy Central Hot Water System For The Residential Project In Shenzhen

Abstract:Currently,energy and environment have been attracting widespread concern from the society.As a result of China's accelerating pace to build an all-around moderately prosperous society,the rapid growing increase of energy consumption will bring our country greater environmental pressure.It has become a consensus to improve energy utilization efficiency,reduce consumption of conventional energy,and make rational use of renewable energy.Energy consumption of hot water is an important part of our energy consumption in residential buildings.Accompanied by the ever-improving living standards,this kind of energy consumption will grow substantially,especially in such a hot and humid city like Shenzhen.The subject will adopt the academic approach by combining theory analysis with practical research,connecting theory with real-life project.First of all,related renewable energy theory of solar energy and air energy will be listed to study the structure and function of solar energy collector.Suitable solar energy collector will be found after performance contrastive analysis.Secondly,multi-system hot water supply of solar energy with auxiliary heating equipment will be studied.We will make several effective comparisons of economical efficiency and take the local characteristics,policies and regulations of Shenzhen into consideration.Then,system model of the project will be selected.Finally,solar energy with air energy pumping heating system is applied to make use of solar energy and air energy to the biggest extent.This paper will introduce in detail design of the water heating system and further design during construction,project construction,inspection and acceptance,gain of energy-saving certification of the project.The experience can be reference for similar projects to be more economical,energy-saving,low-carbon and environment-friendly,making them closer toward green ecotecture.
