What is the difference between a window-style fresh air system and a central fresh air system?
Central fresh air system, the general choice of outdoor air source is relatively clean place to collect. Conventional, high-altitude air quality relative to the ground air is relatively high quality, and then after the system to make the air quality of households higher. And the window of fresh air outdoor air collection is difficult to determine its quality. The lower the floor, the more serious the pollution of outdoor air, directly affecting the introduction of indoor air quality. In addition, the worse the outdoor air, the more the window window fresh wind loss, increase the use of cost.
Window style fresh air system is mainly installed in the windows on the outlet, the structure is more simple than the central fresh air system, Qing Jie relatively simple. Central fresh air system is mainly the use of multiple pipelines will be different indoor outlet together to achieve uniform control, for different indoor transport of fresh air. In fact, the purpose of both is to change the fresh air for the room
(Low noise), low speed and full heat exchange core small and small cross-sectional area, and the air filter effect is useless and so on, resulting in heat recovery The effect and air purification is minimal. The direct consequence is that the outdoor unclean air is sent directly to the room, and it will damage the comfort of the room and increase the energy consumption of the air conditioning. From this point of view, the central new wind built-in heat exchange module is indeed a big advantage.
From the use of operating point of view, most of the window style of fresh air does not have air quality monitoring, filter replacement reminder, adjust the temperature capacity, negative ion release, UV sterilization capacity is far lower than Schmaboth wall fresh air system.
The central fresh air system belongs to the tube mechanical ventilation device, it is the outdoor fresh, oxygen-enriched air filter after the introduction of indoor, while the indoor air pollution outdoors, is the two-way flow of air exchange, is conducive to the housing air Organization, fresh air ventilation effect is good;
Window style fresh air, as the name suggests in the windows to install the air handling products, mechanical into the wind naturally out of the wind, the working principle of the introduction of fresh air from the outdoor after the indoor into the indoor air pollution from the doors and windows out of the gap. Suitable for small area room applications, otherwise it is not conducive to the formation of airflow organization, ventilation effect decreased.
