Energy-saving environmental protection air conditioner is the use of "direct evaporation refrigeration" natural phenomenon, outdoor fresh air through the environmental protection air conditioning machine filtering and cooling, a large number of cool air into the room, and will be indoors with the conductive odor, dust, the temperature of the turbid air discharged outdoors, after such a continuous cycle, so that the indoor temperature is lowered. This kind of air conditioner is characterized by energy saving, power consumption than the traditional air conditioning to reduce nearly 90%; outdoor air after filtering and cooling, send out fresh, clean, low-temperature air; less investment, low initial installation costs, low maintenance costs, economic and durable. Due to its remarkable power saving, good cooling effect and investment saving, it is welcomed by many small and medium-sized processing enterprises.
In order to improve the strength of the product enclosure and aging resistance, environmental protection air conditioning machine shell all use glass fiber reinforced plastic material, glass fiber reinforced plastic environmental protection air conditioning machine main improvement is the shell from stainless steel spraying changed to glass fiber reinforced plastic, its internal structure, ** with the function did not change. In terms of price has been reduced, so that the energy-saving environmental protection air conditioning machine market to a more competitive height. An air conditioner with FRP amounted to more than 40 kg, FRP environmental protection air conditioning machine shells are mostly hand-laid molding process.
Although our country is the world's largest land area, but according to the per capita possession of resources, or a relatively resource-poor countries.
Therefore, energy saving and environmental protection in China's sustainable development is of great significance. Energy-saving environmental protection air conditioning because of its significant power savings, good cooling effect, investment, by many small and medium-sized processing enterprises welcome. In recent years, the development of environmental protection air conditioning machine is very fast, the market outlook is good, hand-paste glass fiber reinforced plastic environmental protection air conditioning machine shell is difficult to keep up with the development speed of environmental protection air conditioning machine, some energy-saving environmental protection air conditioning manufacturers use SMC molding process to produce glass fiber reinforced plastic environmental protection air conditioning machine shell, that is, the use of a new type of thermosetting SMC composite materials. SMC composite materials is Sheetmoldingcompound abbreviation, that is, sheet molding plastic SMC composite material is the abbreviation of Sheetmoldingcompound, that is, sheet molding plastic. The main raw materials by GF (special yarn), UP (unsaturated resin), low shrinkage additives, MD (filler) and a variety of additives. It first appeared in Europe in the early 1960s, and around 1965, the United States and Japan developed this process one after another. China in the late 1980s, the introduction of foreign advanced SMC production lines and production processes.
SMC material has the advantages of superior corrosion resistance, light weight and engineering design is easy, flexible, etc. Its mechanical properties can be comparable with some of the metal materials, with good designability, high strength, waterproof, corrosion resistance, not easy to pollute and so on. Therefore, the FRP environmental protection air conditioner shell made of SMC composite material is characterized by: light weight, high specific strength, impact resistance, its density is about 1/4 of the density of steel, 2/3 of the density of aluminum, but the strength is very large, and its tensile strength is close to that of ordinary carbon steel, and the bending strength and bending elastic modulus is 8 to 10 times of the ordinary plastic profiles. Acid and alkali resistance, corrosion resistance, anti-aging, SMC materials are excellent corrosion-resistant materials, acid, alkali, salt, most of the organics, seawater, and moisture have a better resistance, for the role of microorganisms also have the performance of resistance to the role of its long service life.
