[0032] The specific embodiments of the present application will be further described with reference to the drawings.

[0033] Embodiment:

[0034] The embodiments of the present application disclose a multifunctional fresh air handling unit, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, including the chassis 1, the rectangular chassis 1 has left side plate 11 and right side plate 12. Left side plate 11 is provided with outdoor air inlet 21 and outdoor air outlet 22, right side plate 12 is provided with indoor air inlet 31 and indoor air outlet 32, the first partition 41 is provided in the chassis 1 to divide the left side plate 11 area into outdoor air inlet chamber 51 and outdoor air outlet chamber 52, the second partition 42 is provided in the chassis 1 to divide the right side plate 12 area into indoor air inlet chamber 53 and indoor air outlet chamber 54, the first air valve module 61 is provided between the first partition 41 and the second partition 42, the first air valve module 61 is used to control the on-off of the outdoor air inlet chamber 51 and the indoor air outlet chamber 54. The first partition 41, the second partition 42 are used to divide the space into upper and lower layers.

[0035] It should be noted that, in Figure 1 , the reference leads of the outdoor air inlet chamber 51 and the indoor air inlet chamber 53 are in dashed lines, indicating the internal space of the position.

[0036] The exhaust fan 71 is assembled in the outdoor air outlet chamber 52 for outdoor exhaust, and the air supply fan 72 is provided in the indoor air outlet chamber 54 for indoor air supply.

[0037] The coarse filter module 81 is assembled in front of the first air valve, the full heat exchange module 82 is assembled behind the first air valve, and the high-grade filter module 83 is assembled behind the full heat exchange module 82. The coarse filter module 81, the full heat exchange module 82 and the high-grade filter module 83 are existing products, and there are other names in the market. The other names of the coarse filter module 81 and the high-grade filter module 83 are air cleaner, air filter, etc. According to the precision requirement of the user for air filtration, it can be divided into coarse filtration, fine filtration, etc. The full heat exchange module 82 is the core component in the fresh air system, which realizes the energy recovery between indoor and outdoor air through high-efficiency heat exchange technology, thereby significantly improving the energy saving effect of the system and indoor comfort. The core device of the full heat exchange module 82 is the full heat exchange core. When the indoor air passes through the full heat exchanger, it first contacts the heat exchange core; at the same time, the outdoor fresh air also enters the full heat exchanger and contacts the other side of the heat exchange core. Through the special channel and material of the heat exchange core, the heat (or cold) in the exhaust air is transferred to the incoming fresh air, thereby realizing the preheating (or precooling) and humidification (or dehumidification) of the outdoor air. This process not only realizes ventilation, but also maintains the stability of indoor temperature and humidity. This module can also be purchased and assembled in the market.

[0038] A bypass chamber 55 is separated by a rear partition 43 on the rear side of the cabinet 1, the rear partition 43 is provided with a first through port 431 and a second through port 432, the first through port 431 is communicated with the indoor air inlet 31, the second through port 432 is communicated with the rear side of the total heat exchange module 82, the first through port 431 is equipped with the second air valve module 62, and the second through port 432 is equipped with the third air valve module 63. The first through port 431 is triangular, so as to adapt to the installation position and shape of the total heat exchanger.

[0039] The outdoor air inlet 21 is equipped with the fourth air valve module 64. The outdoor air outlet 22 is equipped with a check valve 65.

[0040] The first partition 41 and the cabinet 1 are provided with a first positioning groove rail 91, the coarse filter module 81 is slidingly assembled on the first positioning groove rail 91, and the second partition 42 is provided with a second positioning groove rail 92, and the high-level filter module 83 is slidingly assembled on the second positioning groove rail 92. Through the first positioning groove rail 91 and the second positioning groove rail 92, it is very convenient to assemble (replace) the coarse filter module 81 and the high-level filter module 83.

[0041] In order to better adapt to the direction of air flow, the coarse filter module 81 and the first air valve module 61 are inclinedly arranged. The high-level filter module 83 is vertically arranged. In this way, the air resistance can be reduced.

[0042] The front side of the cabinet 1 is provided with a side-opening maintenance door 13, and the inside of the cabinet 1 is provided with a control device 10 of the whole machine.

[0043] It can work in multiple modes, for example, mode 1: fresh air mode, the indoor and outdoor temperature difference is large (-30℃ to 25℃) under the condition of operation, at this time, the first air valve module 61 is opened, the fourth air valve module 64 is opened, and the second air valve module 62 and the third air valve module 63 are closed. Through the total heat exchange module 82, the energy loss is reduced, and the indoor heat or cold is recovered: in summer, the cold is recovered, and in winter, the heat is recovered. The outdoor air passes through the outdoor air inlet chamber 51, passes through the coarse filter module 81, passes through the first air valve module 61, then passes through the total heat exchange module 82, and then passes through the high-level filter module 83, and reaches the indoor air outlet chamber 54, and the fresh air is sent out by the air supply fan 72. The indoor air enters the indoor air inlet chamber 53, recovers energy (heat or cold) through the total heat exchange module 82, and then reaches the outdoor air outlet chamber 52, and the air is discharged by the exhaust fan 71.

[0044] Mode 2: inner circulation mode, in the case of poor outdoor air quality, PM2.5 reaches 200 or more, the machine runs in this mode, only the indoor air is circulated and filtered, at this time, the second air valve module 62 and the third air valve module 63 are opened, the first air valve module 61 and the fourth air valve module 64 are closed, and no outdoor air is introduced. At this time, the machine is just an air purifier. The indoor air enters the indoor air inlet chamber 53, passes through the high-level filter module 83, reaches the indoor air outlet chamber 54, and is sent out by the air blower 72.

[0045] Mode 3: bypass mode, which is started in different seasons. In spring and autumn, the outdoor temperature and the indoor temperature are not much different (outdoor: 20-28℃, indoor: 25-28℃), or in summer, the indoor temperature is high and the outdoor temperature is low at night. The bypass mode can be used. The second air valve module 62 and the fourth air valve module 64 are opened, and the first air valve module 61 and the third air valve module 63 are closed. At this time, the fresh air does not exchange heat with the exhaust air through the total heat exchange module 82, which can reduce the air resistance and prolong the service life of the total heat exchange module 82. In summer, the cool outdoor air can be introduced without using air conditioning, achieving the effect of energy saving and emission reduction.

[0046] Mode 4: automatic module, which can switch between mode 1, mode 2 and mode 3.

[0047] As can be seen, the fresh air handling unit of the present scheme can be used in different modes in different working conditions, achieving the effect of energy saving and emission reduction. The newly added inner circulation mode can be used as an air purifier, and the bypass function can save energy in special environments and avoid heat exchange. In some seasons, the use of heat exchangers will increase a lot of energy consumption, so this bypass function is added, thus achieving the purpose of energy saving and emission reduction.

[0048] The above embodiments only illustrate the principles and effects of the present invention, and are not intended to limit the present invention. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, any equivalent changes made in terms of structure, shape, principle, etc. of the present invention shall be covered within the scope of protection of the present invention.
