Analysis On Application Of Renewable Energy Utilization System In Natatorium

With the increasing use of energy,the energy shortage is becoming more and more serious,and the environmental protection is becoming more and more important.This paper analyzes the present situation of the domestic and international solar energy and waste water heat energy recovery and utilization.Focusing on the analysis and research of air conditioning and heating in natatorium,the auxiliary gas system of solar-sewage heat source is put forward.Firstly,this paper introduces the solar energy system and the waste heat recovery sewage source heat pump system.The design of swimming pool solar-sewage source heat pump system,based on solar radiation intensity changes with the weather and other factors are divided into four kinds of operating modes:solar heat exchanger operation mode(solar radiation intensity is high),solar heat pump operation mode(solar radiation intensity decreases)combined operation of sewage source heat,solar mode(the sun the radiation intensity of the further decrease),sewage source heat pump operation mode(solar radiation intensity is very low).Secondly,the theory and modeling of each component and four operation modes of the solar water source heat pump system are analyzed.According to the thermodynamic laws of energy balance and energy balance calculation for the system,using TRNSYS software to establish the system model,the four modes are simulated.The conditions are the volume of the fixed water tank,the change of the solar collector area,the inlet water temperature,the flow rate and other parameters.Finally,through the analysis and design of the solar and sewage source heat pump project of the new campus natatorium of China Medical University,the optimal allocation scheme is finally obtained by relying on the theoretical basis and modeling analysis.The total building area of the new campus natatorium of China Medical University is 5495,with a total building area of 5495.The amount of heat required for the whole year is 2286725 kW.H,the solar collector is 1335489 kW h,the waste water provides 804825 kW.The utilization of renewable energy solar and sewage is 87%of the total energy consumption,Billy Gas can save 770 thousand annually,save 2412 tons of standard coal and reduce carbon dioxide emissions by 6488 tons.
