Although there is no strong data to prove whether the ventilation system can really eliminate indoor harmful gases and pollution, we also have to admit the advantages of ventilation systems. For example, this kind of fresh air system has become a standard in many countries in Europe, as long as there is a house must have a fresh air system, otherwise it will not be allowed to sell, and as long as the installation of new air system can offset part of the tax. It can be seen that the existence of the fresh air system does put forward a higher standard for our life, the fresh air system has also given us a lot of warnings, and the fresh air system lets us face up to the demand for "indoor fresh air". Because there is not yet an absolute standard, there are many kinds of "fresh air systems" in the market, and the brand quality is uneven. So in the purchase, must be careful.
Purchase of fresh air system
The fresh air ventilator is a small ventilation device for changing the air in the room. When choosing, we should determine the air volume, static pressure loss, outlet total pressure, input power, exchange efficiency, noise and so on.
It is necessary to meet the requirements of the relevant regulations, and the heat exchange efficiency value corresponding to the air volume needs to meet the corresponding standards.
Under normal circumstances, when the fresh air temperature is about -10 ° C, there may be frost on the exhaust side, and we must take preventive measures in advance.

The kitchen exhaust smoke, ventilation duct, for the fresh air ventilator accessories variety and quantity to confirm. For example, air pipes, elbows, connectors, seals and plugs, and so on.

Reasonable smoke exhaust ventilation of living room fire is mainly aimed at two key links: on-demand distribution and orderly flow.
The on-demand distribution of the smoke exhaust pipe is to send fresh air to the most needed position of the human body, such as the bed, near the living room sofa, the dining room, above the desk, etc. These areas are the places where the room owner often activities, but also the most need for fresh air, the air intake should be arranged in these areas as far as possible. At the same time, the exhaust outlet should be arranged as far as possible in the dead corners of the room where dirty air accumulates and is difficult to remove, in order to facilitate the complete elimination of hazards.
Orderly flow is the requirement that the fresh air entering the room should have a reasonable (most needed by the human body), smooth (no block or less block), clear and orderly flow direction, the purpose of doing so on the one hand to facilitate thorough ventilation, on the other hand also reduce the work load of the fresh air host, energy saving and emission reduction.
Note: Throughout the process, consumers need to personally participate in the design, face to face with the designer to choose the location of the air outlet and exhaust outlet of their own fresh air system, because only they can truly understand the activity rules of themselves and their families, so that the indoor air freshness can achieve the ideal effect.
