1. Fan of the ventilator
The quality of the fan has a great impact on the service life of the fresh air system. The parameters of the fan performance are flow, pressure, power, efficiency and speed. In addition, noise and vibration are also the main indicators for the investigation of fresh air ventilator. When users choose the fresh air system, they must also consider the two values of purification effect and fresh air volume. There are many models for the fresh air system. However, different models also represent the size of the new air volume to a certain extent. The new volume of the cabinet machine is large, suitable for large places such as the living room, and the VT260 wall-mounted of VTRONIC are suitable for smaller occasions such as bedrooms. The purification effect of the fresh air system depends on the results of tests conducted by a dedicated tester in a closed room.
2. Functions of the ventilator
There is a clear difference between the VTRONIC fresh air ventilator and the air conditioner. VT260 can realize the circulation of air, keep the air exchange with the outdoor, and filter the outdoor PM2.5 and other pollutants to make the indoor air fresh and clean. In general, the VT260 heat recovery ventilator combines the function of ventilation, dust removal, removing home pollution, adjusting room temperature and dehumidification, and can solve most indoor problems.
3. Noise of the ventilator
Many people have a special sensitivity to sound, so when choosing a fresh air system, consider the noise. And Vtronic ventilators, according to different models and air volume, the noise value is between 18-40dB, the noise in the sleep mode is as low as 18dB, which is lower than the national central air conditioning noise standard of 30dB.
4. Filtration layer of the ventilator
The higher the filter grade, the better the effect. In the VTRONIC fresh air system, it is divided into four grades according to international standards: pre-filter, high-efficiency, activated carbon and UV violet light. That is, we know HEPA and achieve HEPA H13 filter. The filtration efficiency of PM2.5 is up to 99.95%. At present, the filter PM2.5 technology used in the fresh air system is divided into two types. One kind of physical interception is to use high-efficiency filter layer to intercept the particles in the air. The VT260 heat recovery ventilator uses pure physical filtration and has no safety risk caused by ozone. . The other is electrostatic dust collection. The principle of high-voltage electrostatic adsorption is used to remove particulate pollutants in the air, but ozone is generated. This should be noted when purchasing. It is best to choose pure physical filtration to ensure clean indoors and safety.
