Research on the Application of Radiative Cooling Film on Temperature Control in Warehouse
The stud on the application of the radiative cooling film material was past on warehouse outer roof,doors and windows with overhead insulation.The data testing and effect analysis of the experimental and comparative warehouses are as follows:the surface temperature of the top of the experimental warehouse had been consistently lower than the ambient temperature,with a maximum temperature reduction of 13.9℃;the maximum air tempera-ture reduction of the overhead layer was 18.9℃ lower than the ambient temperature;The temperature difference between the experimental warehouse and the control warehouse was as high as 11.8℃,with a maximum tempera-ture difference of 8.0℃ for the surface grain(0.3 m)inside the warehouse,and an average temperature difference of 2.6℃ for the entire warehouse.When the air-conditioning was not turned on during the summer season in the experimental warehouse,the maximum surface grain temperature did not exceed 30℃,and then the maximum sur-face grain temperature in the comparative warehouse exceed 34℃ in mid July,the air-conditioning should be star-ted to cool down in a timely manner.It was proved that the radiative cooling film had a significant effect on temper-ature control in grain storage,and was one of the preferred materials for renovation of low-temperature grain stor-age and construction of high-standard warehouses.
