Study on Cooling and Transformation Technology of Radiant Insulation Material Vents in High Temperature and High Humidity Areas
In the high temperature and high humidity grain storage area,the air vent of the grain storage warehouse penetrates more heat under direct sunlight,which easily leads to food heating,water transfer,breeding pests and other problems endangering food security.In the past,insulation materials were usually added to slow the infiltration of heat,but due to the limitations of material technology,the vent still absorbs part of the solar radiation heat,and the temperature of the vent increases significantly.To solve this problem,this study proposes to use radiation refrigeration film to transform the air vent of the cage on the ground,which has remarkable heat insulation effect,low cost and easy popularization.
