"Design-Construction" Research On Green And Healthy Solar-powered Emergency Shelters

In recent years,natural disasters occur frequently in the world.People pay more and more attention to the emergency response mechanism for disaster relief and post disaster resettlement.However,there is a lack of systematic theoretical knowledge and innovative practical experience on the issue of post-disaster resettlement at home and abroad.There are few researches on the rapid resettlement of disaster victims and the development of new disaster relief buildings.Most of the post-disaster resettlement houses are traditional disaster relief tents,temporary boarded houses,although simple and fast,but there is no independent power supply system,poor living environment.Based on the research on the academic achievements and practical cases of emergency relief buildings at home and abroad,especially the design of military and medical cabins involved in the first line of rescue,as well as the design standards of green and healthy buildings at home and abroad.This paper summarizes the three aspects of Green Design,Healthy Design and "Design-Construction".Design influencing factors of solar-powered emergency shelter have been developed.According to the design principle of the solar-powered energy emergency shelter,the project of APEC——Solar-Powered Emergency Shelter Solution(EWG 22 2015A)was designed and the solid model was built.The plan focuses on solving the basic problems in the actual use of the full cycle process.During the experiment,the real model was used for rapid transportation,indoor temperature distribution.The power generation characteristics and total power generation of flexible thin film photovoltaic(FMPV)under different connection modes were tested.The results show that the fan ventilation rate is 0.5m3/s,the indoor and outdoor temperature difference is about 1.4℃,the indoor temperature distribution is uneven,the southern region is obviously higher than the northern region.The full-day power generation of flexible thin film photovoltaic in series mode is about 0.811kW·h.,After changing to parallel mode,the power is increased by 18.2%.At the same time,a model was established in EnergyPlus software to simulate the indoor comfort and energy consumption.The optimal ventilation rate was found to be consistent with the experiment.However,the indoor and outdoor temperature difference was about 0.5℃,and the total photovoltaic power generation was 2.096kW·h,which was higher than the experimental data.Through the complementarity and comparison between the experimental data and the software simulation data,this paper analyzes and summarizes the advantages and disadvantages of the current practical scheme and the direction of future improvement.Through design optimization,we can achieve a more excellent experience in two aspects: rapid construction and comfortable living.Energy supply system needs to have better capacity characteristics,and has a higher degree of integration with the building,convenient transportation and maintenance.Indoor energy consuming equipment is simplified as far as possible to ensure the basic needs.Experimental results and optimization directions of practical schemes are used to verify and supplement the design principles of Solar-Powered Emergency Shelter.Three design principles: Rapid Construction,Comfortable Living and Energy Selfsufficiency.It has reference significance for the design of Solar-Powered Emergency Shelter in the future.
