Principle of the air cooler
The cooling fan (evaporative air conditioner) cooling principle is: when the fan is running, it enters the cavity to generate negative pressure, so that the air flow outside the machine is excessive.
The wet curtain surface of the cold air blower hole forces the dry bulb temperature of the curtain air to drop to the wet bulb temperature close to the outside air, that is, the dry bulb temperature of the air cooler outlet is 5-12 ° C lower than the outdoor dry bulb temperature (dry heat area) Up to 15 ° C), the hotter the air, the greater the temperature difference, the better the cooling effect.
Since the air is always introduced into the room from outside (this is called a positive pressure system), it can keep the indoor air fresh. At the same time, because the machine uses the principle of evaporation and cooling, it has the dual functions of cooling and humidifying (relative temperature can reach 75%). Left and right), used in textile, knitting and other workshops, not only can improve the temperature and temperature increase conditions, but also purify the air, reduce the needle breakage rate in the needle spinning process, and improve the quality of the needle textile products.
The air cooler (evaporative air conditioner) is surrounded by a honeycomb wet curtain using special materials, which has a large surface area, and the wet curtain is continuously humidified by the water circulation system; the high-efficiency low-noise energy-saving fan is installed in the wet curtain air cooler. When the fan is running, the negative pressure of the wet curtain air cooler causes the air outside the machine to flow through the porous wet curtain into the machine, and the heat of the water on the wet curtain absorbs heat, forcing the air passing through the wet curtain to cool down. At the same time, since the water on the wet curtain evaporates toward the air flowing through the wet curtain, the humidity of the air is increased, so the wet curtain air cooler has the dual functions of cooling and humidifying.
Industrial cooling fan principle
Commonly used in the industry is a dry cooling fan. It relies on the evaporation of air through the chiller to cool the forced air outside the tube. It is installed in the floor of the cold storage, called the floor-standing chiller; it is installed on the top of the warehouse, called the ceiling type chiller.
Air cooler (evaporative air conditioner) covers the whole country
Air cooler, commonly known as: Evaporative air conditioner is an air conditioner that has recently used the temperature of tap water to reach the indoor temperature. The main production base is in Fujian, and it has been radiated to various regions of Fujian and Sichuan, Guangdong, Zhejiang, Xinjiang, Hunan, Hubei, Guangxi, Henan, Hebei, Shandong, Shanxi, Jiangxi, Jiangsu, Yunnan, Guizhou, Anhui, Ningxia, Qinghai, Gansu, Shaanxi, Hainan, Inner Mongolia, Beijing, Shanghai, Chongqing, Tianjin, Taiwan, Hong Kong, and Macau.
Black coating is a type of Surface Treatment used to provide a durable, aesthetic and protective finish to metal parts. It is applied to a range of substrates, including steel, aluminum, and titanium, through various processes such as painting, chemical baths or physical deposition.
Black coating provides an attractive, matte finish that reduces glare and reflections. It is commonly used in industries such as automotive, aerospace, and firearms, where aesthetics and durability are essential. The black coating can also be used for functional purposes, such as to reduce friction and wear.
One of the most common types of black coating is black oxide. Black oxide is created through a controlled chemical reaction that forms a layer of black iron oxide on the surface of the metal. This process enhances the corrosion resistance of the substrate and provides a uniform and attractive black finish. Black oxide is also used to provide a matte black finish to gun parts, as well as to increase the conductivity of electrical components.
Another type of black coating is powder coating, which involves applying a dry powder to the surface of the substrate and baking it in an oven. This process creates a durable, weather-resistant finish that is resistant to damage from UV rays and other environmental factors. Powder coating is widely used in the automotive and manufacturing industries, where it provides a long-lasting, high-gloss black finish.
Finally, black coating can also be achieved through physical vapor deposition (PVD). This involves depositing a thin layer of black material onto the substrate through a vacuum chamber. PVD black coatings are very durable, and are often used in high-precision applications such as medical instruments and aerospace components.
In conclusion, black coating is a versatile and effective way to provide a durable, aesthetic, and protective finish to metal parts. Its visual appeal, corrosion resistance, and wear resistance make it a popular choice in a variety of industries and applications. Whether applied through chemical baths or physical vapor deposition, black coating plays an important role in enhancing the performance and longevity of metal parts.
