Where is the central air conditioning air filter applied?

In the past ten years of reform and development, the number of construction and renovation of high-end buildings and hospitals in China has increased rapidly. Central air conditioning systems are also used in large numbers.

China's filtration industry has also been promoted by the rapid development of construction and industry. Many foreign filter manufacturers also set up factories in China. However, the importance of air filtration in general ventilation systems has not been recognized by owners, including many domestic designers and engineers in air conditioning. According to a sample survey of air-conditioning systems for public and commercial buildings in Shanghai, Beijing, and Shenzhen, Guangdong, in 2002, it was generally found that metal mesh or nylon mesh filters were used above, and about 30% to 40% were coarse. For the non-woven filter, only 6 to 8% of the filter is used. At least 60% of the filters are non-standard sizes, which is extremely inconvenient to maintain, replace and modify. In this case, two-thirds of the building's air conditioning maintenance personnel believe that the air filter unit they use can meet the requirements. Generally, the above maintenance personnel do not know how to maintain and use the filter.

Several engineering examples can also reflect this situation:


In 2002, in the large-scale international airport built in the northwest region where wind and sand is serious in China, the filter design in the foreign design scheme is G3+F6+ activated carbon filter. In actual construction, air-conditioning equipment suppliers and airport owners used a nylon mesh + G3 non-woven bag to filter + non-woven activated carbon powder filter in order to reduce costs. This year, the author went to the airport air-conditioning station to see the filter samples, and found that the filter installation method became a G3 non-woven bag filter + nylon mesh filter. (The nylon mesh filter is placed behind for the convenience of installation)


An airport in the south invested 60 billion yuan. In 1996, the French design recommended that the central air conditioning system use F7 filters and activated carbon filters. As the annual cost exceeds the owner's imagination and budget, the requirement is reduced to the F5 level. In actual use, about 5,000 F5 glass fiber bag filters are only used once, and they are replaced by G3 efficiency non-woven filters by the airport property management department, and they are washed regularly. Most of the large airport air conditioning systems in the country use such filters. It is said that an airport in Shanghai also hires people with mental retardation to wash the filter.


Many owners and properties only pay attention to the replacement cost of filters in air-conditioning operation, but do not consider the failure of many equipments in air-conditioning systems due to the use of inefficient filters, the efficiency is degraded, the air-conditioning system is seriously dusty, and finally more flowers are spent. The money goes to repair the equipment and the cost of cleaning the system. A famous building in Shanghai, because the filter efficiency of the air conditioning system is relatively low, after several years of operation in the building, it has to spend millions of dollars to clean the air conditioning system. Even if the air conditioner system uses the best filter, the replacement cost for one year is only about 300,000 yuan.


core advantages:

A. The purified material produced is a hydroxyl-containing oxidant, which can undergo advanced oxidation reaction with pollutants, completely eliminate pollutants and produce non-polluting water and carbon dioxide.

B. Ozone is used as an intermediate product of the purification substance, which is converted immediately after it is produced, so that it can maintain an extremely low ozone content.

C. Using a variety of rare metal catalysis techniques to convert ozone and moisture into purification materials.

Energy Saving Lamp

We supply various energy saving lamp, including Half Spiral Energy Saving Lamp, Full Spiral Energy Saving Lamp, 4U Lotus Lamp, 2U Energy Saving Light Bulbs etc.

The below information will help you to know more about energy saving light.

Which lamp is most energy-efficient?

LED bulbs

Generally, the most energy efficient lighting technology you can buy for your home is the Light Emitting Diode (LED).

Do energy-saving bulbs really work?

CFLs use up to 75 percent less energy than traditional incandescent bulbs. CFLs can last up to 10 times longer than incandescent bulbs, saving on production and disposal costs. These energy efficient light bulbs produce less heat saving on cooling costs.

Do LED lights run your electric bill up?

LED lights are definitely cheaper than their counterparts. Not only do LED's consume less energy, but the bulbs also use energy more efficiently, which saves a lot of money.

How does the energy-saving lamp work?

In a CFL, an electric current is driven through a tube containing argon and a small amount of mercury vapor. This generates invisible ultraviolet light that excites a fluorescent coating (called phosphor) on the inside of the tube, which then emits visible light.
