Description
Technical Field
The invention belongs to the technical field of air treatment, and particularly relates to a fresh air fan.
Background
In order to improve the indoor air quality, various fresh air systems gradually emerge, and the main working principle of a fresh air machine is as follows: carrying out PM2.5 and other dust removal treatments on outdoor fresh air for multiple times, and introducing the fresh air into a room after the fresh air meets the requirement of cleanness; in view of the operating principle of the fresh air fan, the resistance of outdoor air passing through the filtering device is large, the power of the draught fan needs to be greatly improved when the fresh air flow is improved, the power of the draught fan can bring large working noise, and the comfort level of indoor personnel is further reduced.
Most of the fresh air fans in the prior art only have one air outlet, and the air outlet is generally arranged at the upper part of the fresh air fan or the upper part of a room, so that laminar airflow structures are not formed in the room, and the indoor air replacement rate is low; limited by the fresh air fan intake, when a plurality of rooms need to improve the indoor air quality, one technical scheme among the prior art sets up solitary new trend system for every room, and this technical scheme's economic cost and engineering volume are very high.
The second technical scheme in the prior art is that a wind pipe system is arranged, and fresh air at the air outlet of a fresh air fan is introduced into different rooms by using the wind pipe system, the wind pipe system needs to be provided with a complex wind pipe system, and a plurality of pipelines are arranged to extend to different rooms along the top of the room, so that the wind pipe system is not only troublesome to arrange and occupies too much indoor space, especially for the rooms which are already decorated, the modification and installation workload is large, and the damage to the appearance is huge, but also the wind outlet of each room of the wind pipe system is arranged at the top of the room, so that the replacement efficiency of the fresh air in the room is low, especially in winter, the temperature of the treated fresh air is high, the fresh air can be accumulated at the top of the room after entering the room, the user experience degree is obviously reduced, if the temperature of the sucked fresh air is reduced, the room temperature can be reduced, on the contrary, the replacement efficiency of new and old air in the room is reduced, and when the downward air outlet pipeline is arranged to guide the air outlet to the lower part of the room, the indoor space needs to be further occupied, so that the appearance is influenced; according to the technical scheme, the air quantity control and matching of different air outlets of the unified air pipe system are complex, the air quality of each room cannot be accurately controlled, the phenomenon that the air replacement period of some rooms is short and the air replacement period of other rooms is long often occurs, and therefore the problems are overcome.
Above-mentioned technical scheme still exists to have the restriction to the position that new fan set up, and especially the new trend system in two adjacent rooms can't match the decoration in the room, and the nimble mounted position of selecting.
Due to the problems, the experience of the user is poor. Therefore, those skilled in the art are dedicated to develop a new fresh air system to overcome the above problems, or to develop a targeted improvement scheme for a specific type of scene.
