Feature type selection
Many houses have a square type, north and south impermeable, poor ventilation problems, indoor stay for a long time is easy to feel stuffy, this situation is very necessary to install a two-way flow fresh air system, mechanical air supply and exhaust assistance will be outdoor fresh air into the indoor, while discharging indoor polluted air.
For some refrigeration and heating seasons indoor and outdoor temperature differences, open cooling / heating time is long, it is recommended to install a full heat exchange fresh air system, outdoor air through heat exchange into the room, pre-cooling / preheating treatment, play an energy-saving effect at the same time, the air sent in will be closer to room temperature, more comfortable.
In areas with serious air pollution or large-scale construction near the community, long-term dare not open windows, it is recommended to install a fresh air system with efficient filtration, and the specific filtration level depends on the local pollution situation. The outdoor air is efficiently filtered, which can effectively remove dust, PM2.5 and other pollutants, effectively reduce the dust entering the home, and reduce the frequency of cleaning and cleaning.
Air volume selection
The appropriate fresh air volume can play the effect of ventilation and purification, the fresh air volume is too small, the room ventilation is insufficient, and the reasonable ventilation and purification effect cannot be achieved; Excessive fresh air volume will increase the load on the machine and cause energy loss.
The amount of fresh air volume can be calculated according to the number of air changes or the per capita fresh air volume. The number of ventilation is generally selected 0.5-1 times, 50-80㎡ house, generally choose 150 air volume; 80-120 ㎡ house, generally choose 250 air volume, 120-180 ㎡ house, generally choose 350 air volume, of course, a larger area of the house may need a new fan with a larger air volume.
However, in actual use, the larger the air volume of the model, the greater the noise generated, pay attention to the selection of the appropriate installation ceiling position, the choice of sound-deadening sponge, the appropriate pipe type, etc. for noise reduction treatment, suitable design and installation will also better play the role of fresh air equipment. In addition, the most effective means of filtering PM2.5 is the HEPA filter, and the fresh fan with efficient filtration also means that the air volume increases, which may increase the operating noise, and it is necessary to pay attention to the balance of air volume, noise and efficiency when choosing.
