The characteristics of the silica gel heat recovery rotor are: On an aluminum alloy substrate with a thickness of 0.06 to 0.07mm, adsorption coatings containing silica gel components are applied on both the upper and lower sides. The purpose is to utilize the nano-scale voids or pores inherent in the surface and interior of the silica gel particles to constantly adsorb and release water molecules and other types of molecules in the air flow. The potential temperature energy in the molecule is recovered through adsorption (adsorption) and desorption. Meanwhile, during the process of adsorbing and releasing water molecules, it can effectively regulate the environmental humidity. The width of the silicone rubber heat recovery rotor is 100 to 280mm. The manufacturing process of the formed and rolled air duct products is basically the same as that of the rotor production process. The shortcomings of the silica gel heat recovery rotor lie in: 1. It cannot effectively prevent the mixture of harmful molecules; 2. It has high inertness. Under long-term approximate conditions, its latent heat efficiency decreases significantly. It can only be improved and enhanced after regeneration.
