What are the disadvantages of the window fresh air system

Disadvantages of indoor window-type fresh air

Due to the installation requirements of the full heat exchanger, the fresh air and exhaust air need to be concentrated together during the installation, which will bring difficulties to the system layout. In addition, when the pressure difference between the exhaust air and the inlet air is large, there will be a small amount of air leakage through the separator seal, but these situations can be avoided by pressing the supply air in and sucking out the exhaust air.

The window fresh air system is an independent air handling system composed of fresh air ventilator and pipeline accessories, which uses a high-pressure head, high-flow and low-power DC high-speed motor to drive the centrifugal fan to supply air from one side to the room, and the other side to send dirty air from the exhaust fan to the outside.

When the air is supplied, the air entering the room will be filtered, sterilized, aerated and exchanged with cold and heat, and when the air is exhausted, the heat will be exchanged, and most of the energy will be sent back to the room through the system. The fresh air system creates a clean and healthy air environment in the room through purification and ventilation.

Advantages of indoor window-type fresh air

Continuously discharge indoor polluted air, odor, formaldehyde and other polluted air outdoor, and then send outdoor fresh air into the room after purification and energy exchange, so that the indoor fresh air circulation can be maintained 24 hours a day. Removing dust from homes and workplaces, removing dust and killing bacteria when air is introduced, creating a comfortable environment.

Indoor garbage, new furniture, tobacco, etc., are quickly discharged from the outside to prevent odors in kitchens and bathrooms. Reduce indoor moisture, avoid mold of indoor furniture and clothes, and at the same time, the moisture is small to facilitate heating in winter, and the energy consumption is small.

Advantages: The high-efficiency anti-fouling filter of the window fresh air system can prevent smoke and dust germs. As the climate changes, the smoke and dust of germs in the air will increase, and the elderly and frail are very likely to get respiratory diseases.

Installing a window-type fresh air system can remove harmful substances in the air and maintain the freshness and cleanliness level of indoor air quality. At the same time, such as the smell of smoke at home and the kitchen fumes for cooking, you can also remove the indoor odor through the window ventilator. And it can also ensure the safety of people and property.

Now there are children in their homes, without opening the window, they feel that the indoor ventilation is blocked, and their breathing is not smooth, and they are worried that the child will jump up and down when they open the window, and accidentally fall out of the window. A window-type fresh air system is installed, so you can ventilate your home without opening the windows.

Disadvantages: The window fresh air system can only be used at home, and the air volume cannot meet the ventilation requirements for large areas of shopping malls and factories.

Advantages and disadvantages of fresh air systems.

1. Provide fresh air. You can enjoy the fresh air without opening the windows, making the human body healthier.

2. Expel harmful gases in the room. For example, formaldehyde, cigarette smell, bacteria, viruses and other harmful gases, so as to protect children and the elderly from toxic gases.

3. Anti-mildew and odor removal. The indoor cavity is sometimes simple and damp, which affects human health, and the polluted air is discharged in time to prevent mold and bacteria, which is conducive to prolonging the service life of household products.

4. Reduce noise pollution. There is no need to endure the distraction caused by opening windows, making the room quieter and more comfortable.

5. Dustproof. Avoid opening windows to bring a lot of dust, effectively filter the outdoor air, and ensure that the air entering the room is clean.

6. Safe and convenient. In order to avoid property and personal safety hazards caused by window opening. Even if there is no one at home, it will automatically imitate the balance of the wind.

Disadvantages of fresh air system.

1. It will consume indoor cold (heat), because the fresh air system needs to be continuously exhausted and supplied with air, and if it is used with air conditioning, it will cause loss to indoor cold (heat), which can reduce indoor energy loss and save energy.

2. There is a certain amount of investment in the early stage. There are many types on the market, and the cheaper ones are less expensive, with poor performance and more energy consumption. Although the high-quality intelligent fresh air system requires more investment in the early stage, the later cost of the fresh air system is also faster.

3. Replace the filter regularly, if the filter is not cleaned in time, resulting in indoor pollution sources, the filter screen and movement of the fresh air system or fresh air device should be replaced in time. Normally, it can be replaced once every 2-3 months, and if the air quality is poor, it is recommended to replace it once a month.

Advantages: 1) You can enjoy the fresh air of nature without opening the window;

2) Avoid "air conditioning sickness";

3) Avoid mold of indoor furniture and clothing;

4) Remove the harmful gases that are released for a long time after interior decoration, which is beneficial to human health;

5) Adjust the indoor humidity and save heating costs;

6) Effectively eliminate all kinds of bacteria and viruses in the room;

7) Ultra-silent.

Disadvantages: 1. There are many pipelines (long pipes are required for air inlet and exhaust), installation is troublesome, and the cost is relatively high;

2. In the process of heat exchange, condensation will inevitably occur, breeding mold and affecting air quality;

3. The pipeline is long and narrow, the air supply pipe and fan are not easy to clean and maintain, and after 2 5 years, the phenomenon of secondary pollution will be more serious.

In the case of maintenance and cleaning conditions, this messy system can be considered for use, and is more suitable for medium and high-end home users.

The advantages and disadvantages of the fresh air system are as follows: Disadvantages of shooting
