Recently, Yangzhou Solar Solar Energy Co., Ltd. has gained a lot of attention due to its promotion of "full vacuum heat preservation solar energy." So what exactly is a full vacuum heat preservation, or polyurethane vacuum full insulation technology?
As we all know, the insulation tanks of solar water heaters are basically made of polyurethane foam insulation, which is to inject polyurethane foam into the insulation chamber of the insulation tank, and then foam forming to form a polyurethane foam insulation layer in the insulation chamber. Polyurethane foam has a good thermal performance, thermal conductivity is generally 0.023w/m*k, is a good thermal insulation material insulation effect.
So why did Yangzhou Rilita Solar Co., Ltd. propose the concept of vacuum insulation?
Because they use a more efficient insulation material - vacuum insulation board. Vacuum insulation board (VIP board) is an abbreviation of English VacuumInsulationPanel. It is a composite material adopting the principle of vacuum heat insulation and special structure. The schematic diagram of the structure (Fig. 1) mainly consists of three parts: Insulating material of the core part, Gas getter (Getter) and high-barrier composite film (Barrier). Because the vacuum insulation board can effectively avoid the heat transfer caused by air convection, the thermal conductivity can be greatly reduced, less than 0.005w/mk, which is the most advanced high-efficiency insulation material in the world.
At present, vacuum insulation panels have been successfully used to improve the insulation layer of refrigerators, and have achieved good results. For example, vacuum insulation panels produced by Fujian Saite New Materials Co., Ltd. have been widely used in refrigerators of famous companies such as Haier and LG. In application, vacuum insulation panels are generally filled with polyurethane foam filled insulation chambers, which is currently one of the main means of applying vacuum insulation panels internationally.
Since the vacuum insulation panel can improve the insulation layer of the refrigerator, the vacuum insulation panel can also improve the insulation effect of the solar water heater insulation tank. Solar water heater insulation tank using vacuum insulation board is also very simple, just a slight change in the original polyurethane foaming process, in the casting of polyurethane foam material before the vacuum insulation board (Figure 2) is filled into the insulation sandwich, that is, vacuum insulation Board with polyurethane foam filled solar water heater insulation tank insulation chamber.
The use of this technology can bring two benefits: First, it can improve the insulation performance of the water tank; Second, it can reduce the amount of polyurethane foam, making solar water heaters more environmentally friendly.
In the current situation of universal homogenization of solar water heaters, adopting high and new technology to increase the technological content of products, and at the same time it is a positive publicity for the company's brand image, is indeed a thing with many advantages.
