Different Colors / Materials For Sunshade Nets
Through the new experiment, it can be judged whether it is possible to reduce the air and leaf temperature by using the diffused shade net, and the quality of the crop is improved by using the aluminum oxide shade, which also shows the new light dispersion, and the material of the shade net has a great effect .
According to the temperature test of the shade net material, it means that even if the shade level of the black net is higher, compared with the normal one, if the black net is used, the heat load in the greenhouse will be about 60% higher. Therefore, by using a white screen with high reflectivity, the temperature inside the greenhouse can be reduced.
While diffuse light provided a better environment, which in turn had an impact on crop quality and consistency, the average and peak temperatures dropped significantly over the entire test period. Lower temperatures may result in less water usage and create a more comfortable environment to work in.
Studies have shown that scattered white high-reflective mask materials provide a cooler climate compared to black shading nets, because a white screen has a higher shading rate than the same PAR light-transmitting black.
When solar radiation hits a sunshade, some of the radiation is reflected back into the atmosphere, part of the radiation is absorbed by matter and part of the radiation is conveyed through the screen, net into the greenhouse. How much solar radiation is reflected, absorbed or emitted depends on the material used for the sunshade, net function, reflection and transmission and absorption are 100%.
Because of the white highly reflective film, a white screen reflects most of the solar radiation. If the shade net material is a black net, on the other hand, it absorbs most of the solar radiation. This means that black shades will achieve higher temperatures. With both white screens and black sunshades, the net absorbs heat and reradiates heat to the surrounding environment.
