Energy saving air-conditioning machine is the use of "natural phenomenon of direct evaporative cooling", the outdoor fresh air through the environmental protection air conditioner filtering and cooling, a lot of cool Everfount into the interior, and will be discharged with guide indoor dust, taste, high temperature cold air outside, through continuous cycling, the indoor temperature is reduced. The characteristics of this kind of air conditioning is energy saving, power consumption reduced by nearly 90% compared with the traditional air conditioning; outdoor air is filtered and cooled, send fresh and clean and low temperature air; less investment, low cost of installation, low maintenance cost, economic and durable. Because of its remarkable power saving, good cooling effect and low investment, it is welcomed by many small and medium processing enterprises.

In order to improve the product structure of the strength and aging resistance, environmental protection air conditioning casing is made entirely of glass steel material, mainly glass steel improved environmental protection air conditioning machine where it is sprayed to the glass shell made of stainless steel and steel, its internal structure and function has not changed. In terms of price has been down, so that the energy saving and environmental protection air conditioner market into a more intense competition. An air conditioner with FRP amount of more than 40 kg, fiberglass environmental protection air conditioner shell mostly by hand paste molding process.

Although China is the world's first land area, but according to the per capita possession of resources, it is still a country with relatively scarce resources.

Therefore, energy conservation and environmental protection in China's sustainable development is of great significance. Energy saving and environmental protection air conditioner is welcomed by many small and medium processing enterprises because of its remarkable power saving, good cooling effect and low investment. In recent years, the development speed of air conditioner environmental protection is very fast, good market prospects, GRP environmental protection air conditioning casing is difficult to keep up with the speed of the development of environmental protection air conditioner, some energy-saving air conditioning manufacturers using SMC molding process for the production of glass steel environmental protection air conditioning casing, which adopts a novel thermosetting composite material SMC. SMC composites are the abbreviation of Sheetmoldingcompound, that is, sheet molding compound. The main raw materials are made up of GF (special yarn), UP (unsaturated resin), low shrinkage additive, MD (filler) and various additives. It first appeared in Europe at the beginning of the 1960s, and developed in the United States and Japan around 1965. At the end of 80s, foreign advanced SMC production line and production process were introduced in china.

The SMC material has excellent corrosion resistance, the advantages of light weight and easy engineering design and flexible, its mechanical properties can be comparable with some metal materials, has the characteristics of good design, high strength, waterproof, corrosion resistance, not easy to pollution. It adopts SMC glass steel shell features environmental protection air conditioning made of composite material is: the characteristics of light weight, high strength, impact resistance, its density is about density of 1/4 steel, aluminum density 2/3, and the strength is great, the tensile strength and ordinary steel close to the flexural strength and flexural modulus of elasticity is ordinary plastic profile 8 ~ 10 times. Acid and alkali resistance, corrosion resistance, aging resistance, SMC material is excellent corrosion resistant material, has good resistance to acid, alkali, salt, organic matter, water and most humid, also have resistance performance for microorganisms, long service life.
