First, look at the fan.

The quality of fan has a great influence on the service life of fresh air system. The performance parameters of the fan mainly include flow, pressure, power, efficiency and speed. In addition, noise and vibration are also the main indicators for investigating new fans. Users should also consider the purification effect and fresh air volume when choosing the fresh air system. There are many models for fresh air system to choose from, but different models also represent the fresh air volume to some extent. The fresh air volume of the cabinet is large, which is suitable for large places such as living room, and the wall-mounted new fan is suitable for small places such as bedroom. The purification effect of fresh air system depends on the test results of a special tester in a closed room.

Second, look at the function.

The fresh air system and air conditioning in Bergluft, Germany are obviously different. It can realize air circulation, keep the exchange with outdoor air, filter outdoor pollutants such as PM2.5, and make indoor air fresh and clean. Generally speaking, the fresh air system integrates the functions of ventilation, dust removal, home decoration and decontamination, room temperature adjustment and dehumidification, which can solve most indoor problems.

Third, look at the noise level.

Many people are particularly sensitive to sound, so noise should be considered when choosing fresh air system. BERGLUFT Germany Braun, depending on the model and air volume, the noise value is between 27 and 53 decibels, and the noise in sleep mode is as low as 27 decibels, which is 30 decibels lower than the national central air conditioning noise standard.

Fourth, look at the filter.

The higher the filter level, the better the effect. According to domestic standards, BERGLUFT Germany Bolong fresh air system is divided into four grades: coarse efficiency, medium efficiency-medium efficiency, sub-high efficiency-high efficiency and super efficiency. That is, HEPA, which we are familiar with, has reached the level of HEPA H 13, and the filtration efficiency of PM2.5 is as high as 99.95%. At present, there are two kinds of PM2.5 filtration technologies used in fresh air system. One is physical interception, that is, using high-efficiency filters to intercept particulate matter in the air. BERGLUFT Germany Bolong fresh air system adopts pure physical filtration, and there is no safety risk caused by ozone. The other is electrostatic dust removal, which uses the principle of high-voltage electrostatic adsorption to remove particulate pollutants in the air, but it will produce ozone, so pay attention to it when purchasing. It is best to choose pure physical filtration to ensure the cleanliness and safety of the room.

Verb (abbreviation for verb) has the function of heat exchange.

BERGLUFT Germany Bolong fresh air system (central type and cabinet type) has full heat exchange function, which can effectively adjust indoor and outdoor temperature and humidity, actively exhaust indoor dirty and humid air in time, and avoid the accumulation of humid air indoors.
