Does the fresh air system use frequent filter changes?

It is recommended that you replace, especially in winter:

Fresh air system is a new type of indoor ventilation and exhaust equipment, which belongs to the open circulation system, so that people can breathe fresh, clean and high-quality air indoors. Does the fresh air system need to change the filter element?

If it is used for a long time without cleaning or replacement, it will affect the performance of the equipment, shorten its life, and more serious will be scrapped, so that the gains outweigh the losses. If you do not carry out maintenance, these problems will occur, and the filter screen will have dust accumulation, bacteria and viruses breeding, which will affect the filtration and purification, increase the fan current, and cause the motor to burn out. Generally, the filter should be replaced once every 3 months to ensure smooth purification and filtration; The rotation of motors and fans becomes slow and sluggish, the air volume decreases, the operation is insufficient, and the noise increases, which affects the rest of the family; The components may be damp with ash accumulation, which makes the control part fail; If the full heat exchange module is not cleaned in time, the heat exchange rate will be reduced, and the energy consumption will occur. If the inside of the household fresh air system is not cleaned in time and the filter screen is not replaced, the concentration of the introduction will be higher and higher, and secondary pollution will occur.

When the equipment is running, generally do not replace the filter; If the filter cannot be stopped for replacement because the replacement period has expired, it is only allowed to replace the coarse and medium filter without stopping the fan; The sub-high efficiency filter and the high efficiency filter must stop the air supply before they can be replaced; The gasket between the filter and the connecting frame must be tight and leak-free to ensure the filtration effect.

The fresh air system needs to be replaced regularly, and it is generally recommended to replace it once every 4-8 months, and the replacement cycle should be shortened for areas with more serious haze, such as Beijing, Hebei and Henan regions, which is recommended to be 3 months.

The installation steps of the household fresh air system are introduced as follows;

1. Connect the power cord of the host from the switch box first; When there are no special requirements for the power cord, the copper core wire is used.

2. Use the screw rod to hoist the host to the designated position, which is required to be positive, flat and stable.

3. Communicate with the staff of air conditioning, water and electricity pipelines and other facilities to determine whether the on-site pipelines are unblocked, whether the location of the tuyere has an impact on other facilities, and fine-tune the drawings.

4, the installation of the pipeline system, hard pipe every 150cm set up an elevator, the pipeline requirements horizontal and vertical, each joint plastered with PVC glue. Pipeline hose area, every 70cm set up an elevator, elevator bolts using full tooth bolts.

5. The bottom-mounted tuyere is flush with the ceiling, and the side-mounted tuyere is flush with the wall.

6. The connection between the pipeline and the main engine; The connection between the pipeline selected by the project and the air inlet and exhaust outlet of the main engine is a variable diameter or funnel type reducer, and the seams are fixed with tin foil tape, and the requirements are: the tape is pasted flat and can not be wrinkled, the seams should be pasted tightly, and the air leakage can not be leaked, and the tin foil joint needs to be fixed with cable ties.

7. Between the main engine and the exhaust outlet, according to the drawings to see whether there is an oblique tee, leave the exhaust outlet for the ventilation fan.

8. After the installation of the host and pipeline system, contact the electrician at the site to determine the cable requirements and the installation position of the switch.

9. After the installation of the host and pipeline, communicate with the carpenter of the construction site, and propose the data and location of the installation and maintenance port.

10. If there is a window ban installation, the same will be communicated with the relevant personnel after the installation of the host and pipeline and the requirements will be followed.

11. After the decoration of the main body of the project is completed, go to the installation tuyere and check the working condition of the host.

The whole set of fresh air system includes the installation of about 10,000 to 20,000 yuan, the replacement of the filter element depends on the size of the fresh air volume, the larger the air volume, the faster the replacement cycle, almost half a year to a year must be replaced, the cost of replacement is about 300-500 yuan.

Fresh air system. If it is enabled, it will not be turned off in general. The replacement of the filter screen depends on the off-grid grade and the local climatic conditions, if it is a low-grade and medium-grade filter, it will take 3 to 6 months to replace, and if it is a high-grade rate screen, it will take 6 to 12 months to replace.

Of course, if the local climate is harsh, the replacement time needs to be appropriately shortened. <>

If you want better and cleaner air, you can naturally replace the filter more frequently, so as to achieve the purpose of purifying the air. The main reason why you choose to replace the filter is because the filter is a basic consumable in the design itself. Its main function is to keep dust and other pollutants in the air out, but if not replaced, these pollutants will collect on the filter.

Once the fresh air system is turned on, these pollutants may enter the room due to the pressure difference between indoor and outdoor, thereby polluting the indoor air, so it is necessary to replace the filter in time. <>

The filter replacement interval depends on the local air environment to the greatest extent. If the environment is very poor, under normal circumstances, the filter needs to be replaced once every two months to three months. Moreover, the replacement of the filter is not simply to take it out for cleaning, because this will damage the structure of the filter, so that it has no way to better absorb pollutants in the air.

This is also why although the fresh air system has been born for a very long time, it has not entered thousands of households, because its use cost is relatively high. <>

Now there is a new electronic purification filter, which is designed to adsorb pollutants in the air into a designated space through the principle of high-voltage electrostatic adsorption. We only need to open the integrated box within the specified time and clean up the pollutants inside, without replacing the filter, which will not only reduce the cost of using the fresh air system, but also be more efficient and convenient, and it is not easy to have secondary pollution.

The fresh air system does not need to be turned on 365 days a year, and can only be turned on when necessary, and the filter is generally changed once every six months or about a year.

The fresh air system does not need to be turned on 365 days a year, it only needs to be turned on when necessary, and the filter screen is generally replaced for half a year or a year.

No, you don't. When people are not at home, you can turn it off. It would be better to change the filter once a year.

If it needs to be replaced, it can be replaced according to the situation at home, the air can be a little longer and more slippery, and the air quality is not good, and the frequency of replacement can be appropriately increased, which needs to be replaced regularly.

In the process of using the fresh air system, if there is a lot of dust in the indoor air, the filter is easy to get dirty. Does the fresh air system need to change the filter? PChouse will take you to find out.

After using the filter of the fresh air system for a period of time, the filter will gradually saturate and the purification efficiency will be reduced, so it needs to be replaced or cleaned. At present, the method of replacing the filter screen of different types of fresh air systems is not the same, it is recommended that you can read the manual. For some surface-mounted fresh air purifiers, it is relatively convenient to replace.

At the same time, the traditional fresh air system is only pure ventilation, introducing outdoor air to discharge indoor air, and this kind of fresh air system without filtration function naturally does not need to replace the filter. The emerging fresh air system has a filtration function, because the pure introduction of outdoor air is also polluting, sometimes very serious, car exhaust, industrial exhaust and so on. As far as the well-known Huandu fresh air system is concerned, the built-in multi-layer filter, the primary filter is recommended to be changed three times a year, once in haze, once after the catkins, once in winter, and the high-efficiency filter can be changed once a year.

Of course, if you don't change at this pace, it doesn't mean that there is a problem, it's just a reference for the optimal state.

It can be disassembled for cleaning, continuous use, and easy to operate.

The fresh air system generally has multiple layers of filters.

1. Primary filter, something like a screen window. Under normal circumstances, it can be directly rinsed and dried with water, 2. Medium and high-efficiency electronic dust collectors are generally two. The main part of filtering contaminants, GreenWear can be washed without consumables.

3. The other layers are optional, such as activated carbon, sampling balance, etc., which are basically for germs, formaldehyde, ozone, etc., and cannot be cleaned.

Please refer to the manufacturer's manual for the replacement of the filter screen of the fresh air system. Generally, after replacing the filter, it must be reset to be used normally.

Change? The fresh air system is an air purification device that replaces indoor and outdoor air in real time, which will bring us fresh and clean air when it is running, but after long-term use, it is found that the household fresh air system is noisy and the purification effect is not good. At this time, it is necessary to consider whether the household fresh air system should be maintained and cleaned.

Because the fresh fan will be the same as the air conditioner after a long time, it will breed a large number of bacteria and generate dirt, which will affect the use effect of the new fan. Hall Fresh Air tells you how to maintain your home fresh air system

Effectively remove bacteria, discharge formaldehyde, benzene and other harmful gases, and the purification efficiency is as high as the cleaning of the fresh air system - the cleaning of the air outlet and filter.

In the process of operation, the fresh air system will absorb the dust in the air, and the dust is easy to breed bacteria. Do a good job of cleaning, at the same time the filter is regularly replaced, if you have purchased the fresh air system of the filter that needs to be cleaned, be sure to clean it, not sloppy, he is the easiest place to breed bacteria, and bring bacteria into the room, it is best to use a replaceable filter, it is difficult to ensure that there are no residual bacteria when the air quality is poor, and the frequency of replacement can be a little more when the air quality is poor, the following is Hall fresh air H602PLUS filter screen replacement.

Can ordinary fresh air use a high-efficiency filter? Hello, I am glad to answer for you<> pro-ordinary fresh air can be used with high-efficiency filters due to the different characteristics of the clean room, the selection of high-efficiency filters should first be determined according to the different requirements of the clean room, such as the level of grip, the degree of sterility, the degree of temperature and humidity, the degree of fire resistance, and the degree of corrosion. Recently, I saw rfilter high-efficiency filters in the BOE clean workshop, and they are required to be high temperature resistant, moisture-proof, and anti-corrosion.

If you choose Class A or Class B below level 100, you need to select Class C filter if you are above level 100; Under high temperature and high humidity conditions, it is advisable to use a metal separator plate and a metal frame filter; If there is an anti-corrosion requirement, it is advisable to use a plastic separator plate and a plastic frame filter; If there are fire protection requirements, all materials of the filter should be non-combustible, etc. In practice, conventional filters refer to Class A and Class B specified in the high-efficiency air filter standard, which are the most commonly used high-efficiency filters in the design of clean plants, and are generally lower than or equal to 100,000 class A can be selected; 10,000 Classes B can be selected. For conventional high-efficiency filters, the efficiency of particulates can be calculated according to 5 "9s".

The high-efficiency filter is mainly used to filter the following airborne particulate segments, as the end filtration of various filtration systems; **: The selection and configuration of the air filter in the clean area of the 300,000-level 100-level 100-level clean room, generally speaking, the selection of the filter is selected according to the requirements of the clean room grade. rfilter recommends the following configuration requirements for your reference:

100-level purification: plate type G4 (F5) + bag type F7 (F8) + bag type F9 + plate type H13 + (FFU filter unit at the end of the air duct); 1000 level purification: plate type G4 (F5) + bag type F7 (F8) + bag type F9 + plate type H11 + (FFU filter unit at the end of the air duct); 10000 level purification:

plate type G4 (F5) + bag type F7 (F8) + bag type F9 + plate type H11; 100,000 level purification: plate type G3 (G4) F5 + bag type F7 (F8) + bag type F9; 300000 level purification: plate type G3 F5 + bag type F6 F8; Each high-efficiency filter is tested one by one before leaving the factory to ensure the performance indicators of the high-efficiency filter; Hope mine can help you <>

Do you have any other questions?

If the fresh air filter is not installed, it will directly enter the condenser fins and affect the heat conduction, just like the air filter of the car, which will block dust. : As long as it is cleaned regularly, it is an important part that cannot be missing. Easy way to clean your air conditioner:

1.To open the lid on the outside of the air conditioner, you only need to pull the panel open and upward on both sides of the indoor unit with both hands at the same time. Note: Disconnect the power supply before operation.

2.Then, after the lead pin is opened, you can see the left and right filter screens, just pull it down and clean it with water or detergent, and install it again in the original position, and the panel can be buckled down. 3.

It should be noted that if you find that there is a lot of dust on the blades of the indoor unit after taking off the filter, you can use the vacuum cleaner to suck out the dust, which can enhance the circulation effect.
