A sun shade net is an ideal solution to block the rays of the sun that heat greenhouses. The material is UV-stabilized polyethylene knitted fabric that blocks out a specific percentage of light. They can last anywhere from two to eight years, depending on the conditions. You can choose from different lengths and stitching methods to make them fit your specific needs. You can also purchase special-sized versions by sewing and cutting. Sun shade nets are shipped in rolls with a plastic bag inserted into the roll, or in pieces that are individually packaged in a carton box.
Infrared radiation from the sun heats a greenhouse
To understand how infrared radiation from the sun heats greenhouses, we need to understand how the atmosphere absorbs and radiates this energy. As you can see, the atmosphere contains gases with three or more atoms, such as carbon dioxide, methane, and nitrous oxide. These gases absorb infrared radiation and heat the Earth’s surface. The gases are also known as greenhouse gases because they absorb heat from the Earth.
The glass walls of a greenhouse act as partial barriers to infrared radiation. Visible light from the sun is absorbed by the materials inside, while infrared radiation is trapped within the greenhouse’s walls. This trapped infrared radiation warms the greenhouse, allowing tropical plants to thrive. The greenhouse effect is similar to the way the sun heats the interior of a car. A closed window traps outgoing thermal radiation, which warms the car’s interior.
The average temperature of the Earth is a function of the amount of infrared radiation that reaches the surface. However, because the atmosphere absorbs most of the IR that enters the atmosphere, adding more carbon dioxide to the atmosphere does not increase the greenhouse effect. A thirty percent increase in carbon dioxide has only a small impact on the background greenhouse effect. However, doubling the amount of carbon dioxide will make a significant difference, through water vapor. By doubling the amount of carbon dioxide, temperatures will increase by four to six degrees Fahrenheit.
The CO2 molecules are the most powerful greenhouse gases. When exposed to infrared radiation, they absorb this energy and emit it as photons. During the day, this energy is converted to heat by the carbon dioxide molecules in the atmosphere. As they do this, the greenhouses are able to trap the energy from infrared radiation. The resulting heat raises the temperature of the greenhouse, thus contributing to the increase in tem
