How to choose a suitable home for the new air system air pollution is every big city has problems, poor outdoor air quality, so the way through the window ventilation is not satisfactory, then you can choose to install a new ventilation system, but the market of fresh air System variety, how to choose the right air system it? So, now the new air system on the market specifically what are the kind of it? pros and cons is what it? Simple fresh air system affordable easy to install without heat recovery fresh air system commonly known as The air system is simple. Such systems usually belong to the whole system is installed, the more complex construction, piping needs, design and installation of the wind and return air, punching walls. It is more suitable for the construction of buildings in the early stages, before the house has not been renovated or to design and install, has been renovated for housing construction is very difficult. Easy to install and relatively low cost of new wind Panasonic Wall fresh air, and is easy to install wall-mounted installation of new wind, without passing more pipelines, can effectively remove indoor air pollution, add enough fresh air, not to achieve ventilation window. But because they do not bring the heat exchange system, so easy in the winter and summer air system inlet temperature and room temperature difference is large, comfortable enough new wall-mounted fans, but also to a certain extent, increased air conditioning (or heating) workload. And this system is generally without filter, it can not completely eliminate outside noise and dust, suitable for non-cold areas far from the road and room use, are affordable and popular products. Currently, the market has also been a "Window ventilators" simple fresh air system, which works on the edge of the window reserved for air, indoor air is drawn through the fan to come to the indoor air. Guo Zhangeng noted that this window is only designed with ventilation inlets and no outlet, so that air pollution may not be effective and timely manner excluded, and will flow into the fresh air after adventitious, are not guaranteed to be distributed throughout the indoor fresh air. New wind system-wide application of the new air system is based on one side in a closed room with special equipment to send fresh air into the room, and then the other side is discharged to the outside by a special device, the principle in the room will form the "new wind flow field" to meet the interior fresh air ventilation needs. Embodiments are: the use of high flow, low-power centrifugal fan, rely on mechanical strength from one side to the indoor air, the exhaust from the other side with a new fan designed discharged to the outside to form a new way of forced air flow field in the system. In the air, while the indoor air entering into a new air filter, Drugs, sterilization, oxygen. After the host with the new exhaust air heat recovery exchange, recovering most of the energy back through the fresh air indoors. The formation of large-scale borrowing clean space program, to ensure access to the indoor air is clean. In order to achieve the purpose of indoor air purification environment. The new air system Application: Any activity in which someone for a long time, and a poorly ventilated room is necessary to use the new air system. To sum up, household air system (negative pressure ventilation mode) suitable for use in ACH fewer apartments, villas, baby room and other small space places; for more human activity, the number of ventilators more hotels, KTV , Internet cafes and other entertainment venues, rooms, hotels, shopping malls, factories, office buildings, restaurants, banks, classrooms, kindergartens, hospitals and other places Wall ward fresh air, it is best to use the new air unit, because the number of ventilators and more, the energy loss and more, the need to use fresh air heat recovery systems.
