The air inlet of the "ventilation equipment" is equipped with a filtering device, which can effectively avoid the wind, sand, dust, harmful gases and other pollutions that used to open the window to change the air flow into the room. Therefore, it is called a healthy ventilation method. At present, there are mainly three types of ventilation equipment that can be seen on the market: ducted, windowed and wall-mounted.
1. Ducted ventilation system (fresh air system)
The ducted ventilation system is mainly composed of a ventilator, air duct, exhaust vent, air inlet and additional components. Since ducted ventilation is a larger system, it is best to install it first in the rough room.
Start the ventilator to discharge the indoor turbid air from the air outlet through the air duct buried above the ceiling. At the same time, after the air inlet is filtered through layers, outdoor fresh air is introduced to allow the outdoor and indoor air to be fully exchanged. In addition to enjoying fresh air, the host can choose other components according to the needs of the room, such as heat exchange devices, pollen filter devices, humidification and dehumidification devices, temperature intelligent control devices, etc., so that no need to open the window, you can ensure a 24 hour health and comfort Quality of life.
Advantages: It can efficiently and evenly provide the fresh air necessary for the human body to the room, especially the fresh air system with heat exchange, which makes up for the defects of traditional energy-saving houses and creates an energy-saving, soundproof, clean and comfortable living space.
Disadvantages: As soon as the switch is turned on, the entire system will be started, and power consumption is difficult to control.
2. Window ventilator
Attached to the window ventilation position, it is in the shape of a long strip. It can be ventilated and ventilated without opening the window. There are two types of natural ventilators and power ventilators. It is necessary to replace the whole glass when installing the window ventilator, so in order not to affect the normal living, it is recommended to complete the installation before moving in.
The natural ventilator uses the indoor and outdoor air pressure difference (temperature difference and high-level external wind pressure, etc.) to allow the indoor and outdoor air to circulate naturally, or to introduce fresh outdoor air into the room with the help of a power ventilator (with a motor) to form a positive pressure. Then the dirty air is discharged outside through the natural ventilator. The window ventilator can effectively prevent rain, snow, noise, wind sand, insects and other substances from entering the room while ventilating. Even when sleeping, the deflection of the upward air flow will not make the human body feel uncomfortable.
Advantages: can be turned on at any time, energy saving and easy to use.
Disadvantages: Can not be installed in sliding windows of sliding windows.
3. Wall-mounted ventilator
The wall-mounted ventilator looks more like an upgraded air purifier, but the traditional air purifier can only be circulated repeatedly in the indoor closed environment, while the ventilator can achieve indoor and outdoor air circulation. At present, domestic wall-mounted ventilators are designed with single exhaust or single intake air, while purifying the air, using window gaps or door slits to complete the ventilation with the outdoor; and imported products have integrated intake and exhaust air design, which forms a circulation , Some can also be heat-exchanged.
The wall-mounted ventilator is very convenient to install. You only need to punch one or two holes in the wall to install and use it, so if you have finished the decoration and don't want to go any further, you can choose the wall-mounted ventilator.
Advantages: easy installation.
Disadvantages: limited air volume and limited driving space.
