The frame main body 120 in this embodiment may be integrally formed, and since it is basically formed by a vertical partition, it is convenient to form, so that the assembling procedure of the frame 12 may be reduced, and the production efficiency may be improved. In addition, the first top plate 125 and the second top plate 126 connected to the top of the frame main body 120 can be made of foam boards, so that vibration and noise in the operation process of the fresh air fan can be reduced, the mass of the frame 12 can be reduced, and the second top plate 126 is installed at the top of the fresh air inlet cavity.
The following describes several main operating modes of the total heat fresh air machine 1.
Full heat exchange mode. In the total heat exchange mode, the fresh air and the return air need to exchange heat, the bypass air channel is closed at the moment, the fresh air is exhausted indoors through the fresh air outlet cavity after passing through the fresh air inlet cavity, the total heat exchange core 15 and the upper air channel, the return air is exhausted outdoors through the return air inlet cavity, the total heat exchange core 15 and the return air outlet cavity, the first air door 17 is closed in the process, and the fresh air and the return air carry out total heat exchange in the total heat exchange core 15.
A bypass mode. Under this mode, the return air does not carry out the heat exchange with the new trend, and the new fan can open the new trend wind channel also can not open the new trend wind channel, and first air door 17 is closed and the second air door is opened, and indoor return air is discharged to outdoor through return air inlet chamber, lower floor's wind channel, bypass wind channel and return air exhaust chamber in proper order, can realize the quick discharge of indoor return air like this, for example can open the bypass mode when indoor because of the situation such as smoking, peculiar smell leads to under the poor situation of air quality.
An internal circulation mode. Under the internal circulation mode, first air door 17 is opened, and the second air door is closed, and upper air duct can switch on return air inlet chamber and new trend air outlet chamber this moment, and indoor return air is behind the upper air duct of indoor air inlet chamber entering, directly discharges from new trend air outlet chamber behind formaldehyde removal module 144 and fourth filter screen 145, realizes the internal circulation and the purification of indoor air, and this mode is applicable to the poor condition of outdoor air quality.
It can be understood that the utility model discloses a new fan of total heat 1 can also realize other mode.
So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
