| As a technique that can use solar energy to enhance pressure and air rate of natural ventilation.is getting more and more attention.It is an equipment of natural ventilation under the action of heat pressure.It turns heat energy into kinetic energy and bring the new air to the room,in the mean while increasing ventilation rate.Solar ventilation not only enriches the theory of natural ventilation,but also for the further development of natural ventilation provides a new direction,a variety of studies for solar ventilation has also made great progress. However,due to solar radiation instability and intermittent and greatly limits the useand development of solar ventilation,therefore,improve the efficiency of solar energy utilization efficiency and enhanced natural ventilation solar ventilation become an important research problem.Abundant solar summer Chongqing region as the research object,the use ofsolar energy combined with natural ventilation technology,used in the building ’s ventilation system,ventilation room organized to enhance natural ventilation.Especially hot pressing ventilation effect of natural ventilation has the ability toassume more indoor heat load and the removal of indoor pollutants,renewable energy directly applied to natural ventilation,so as to achieve ventilation energy-saving,emission reduction purposes,to ease the energy and environmental pressures,proposed a new energy saving methods.In this paper,first of all solar radiation intensity Chongqing area,the dry bulb temperature,humidity and other meteorological parameters were analyzed.Inthe analysis based on meteorological parameters,for the Chongqing area of solarand solar ventilation shafts are scarce less efficient utilization of solar energy.weproposed indirect solar ventilation.The basic theory of the solar ventilation,solar ventilation proposed indirect basic concepts,basic theory,system components,and indirectly through theoretical calculations to determine the feasibility of solar ventilation.In this pape,a chicken coop for the study,based on the unique characteristics of sheds and ventilation requirements,outdoor solar collector system to determine the likelihood of collector and collector capacity,and to determine the required experimental materials and related test equipment.But also on the theory of heat transfer within a ventilation shaft conducted a preliminary analysis to determine the heat transfer method,elaborated from the conversion of solar energy toheat process works.Finally,experimental test data, analysis of indirect solar ventilation system water flow,air flow and indoor and outdoor temperature ventilation shafts,solar radiation intensity relationship between the changes.Therefore,in this paper,the chongqing area of solar radiation intensity,the dry bulb temperature,humidity and so on meteorological parameters were analyzed,and with a henhouse as the research object,from the theory based on study of outdoorsolar system set hot possibility and set heat ability,determine laboratory needmaterials and relevant experimental equipment,at the same time also on ventilation borehole in hot cantaloupe theory analysis,to determine the heat exchange way,this paper expounds the solar energy to heat energy from the converting process and efficiency.With theoretical analysis and experimental simulation methods,and put forward the ventilation shaft from the collecting solar energy used to enhance natural ventilation this system design, and set up the test bench, theoretical analysis was verified.... |
