[0002] Fresh air units are widely used in places such as residential buildings, office buildings, and commercial buildings. Due to the high degree of airtightness in these places, it is easy to cause indoor air pollution, such as the accumulation of harmful substances such as carbon dioxide and formaldehyde. A fresh air unit is a device for indoor air purification and ventilation, and its main function is to introduce fresh outdoor air and discharge polluted indoor air. By installing a fresh air unit, the circulation of indoor and outdoor air can be realized, the accumulation of harmful substances can be reduced, and thus a fresher indoor air quality can be provided.

[0003] Existing floor-standing fresh air units generally adopt an integrated design, integrating the outdoor fresh air input module and the indoor return air discharge module side by side vertically in one device to form an integrated system. Although this structural setting can save space and simplify installation to a certain extent, there are also some limitations. It can only realize the input of outdoor fresh air and the discharge of indoor return air, and cannot realize the function of circulating indoor return air when outdoor fresh air cannot enter the fresh air unit, and the function is relatively single. In addition, the connection ports of the outdoor fresh air input module and the indoor return air discharge module are usually located on both sides of the device, and the external connection pipes need to be set on both sides of the device to be docked with the connection ports, but this docking method requires more lateral space and is more inconvenient.

[0004] Therefore, it is necessary to propose a floor-standing fresh air unit with more diverse functions and less lateral space required for docking. Content of the Utility Model

[0029] The return air input chamber 112, fresh air input chamber 113, exhaust chamber 114 and heat exchange chamber 115 are all distributed in the inner included angle area between the fresh air treatment section 101 and the air inlet section 102. The return air input chamber 112 is located on the side of this area adjacent to the fresh air treatment section 101, the exhaust chamber 114 is located on the side of this area far from the fresh air treatment section 101, the fresh air input chamber 113 is located in the upper part between the return air input chamber 112 and the exhaust chamber 114 in this area, and the heat exchange chamber 115 is located in the lower part between the return air input chamber 112 and the exhaust chamber 114 in this area. Moreover, the heat exchange chamber 115 is communicated with the return air input chamber 112, fresh air input chamber 113, exhaust chamber 114 and air inlet section 102;

[0030] On the top of the casing 10, there is a connection port 13 corresponding to the fresh air treatment section 101, return air input chamber 112, fresh air input chamber 113 and exhaust chamber 114 in sequence for external connection and communication;

[0031] The total heat exchanger 20 is arranged in the heat exchange chamber 115, and it forms a fresh air delivery channel that communicates the fresh air input chamber 113 and the air inlet section 102 up and down and a return air delivery channel that communicates the return air input chamber 112 and the exhaust chamber 114 laterally;

[0032] The air valve 30 penetrates through the exhaust chamber 114 and the air inlet section 102 in a switchable manner. By its opening and closing, the air inlet section 102 and the exhaust chamber 114 are communicated or cut off;

[0033] The outdoor fresh air input module 40 is arranged between the fresh air input chamber 113 and the fresh air treatment section 101 for inputting outdoor fresh air;

[0034] The indoor return air discharge module 50 is arranged between the return air input chamber 112 and the exhaust chamber 114 for discharging indoor return air.

[0035] Furthermore, in this embodiment, the outdoor fresh air input module 40 includes a supply air fan unit 41 arranged on the top of the fresh air treatment section 101, a heat exchanger 42 erected at the bottom of the fresh air treatment section 101 to separate the fresh air treatment section 101 from the air inlet section 102, and a fresh air filtering unit 43 arranged in the fresh air input chamber 113. When the new type floor-standing fresh air unit operates with fresh air, outdoor fresh air is input from the connection port 13 communicated with the fresh air input chamber 113. After the outdoor fresh air is processed by the fresh air filtering unit 43, total heat exchanger 20 and heat exchanger 42 in sequence, with the operation of the supply air fan unit 41, air is supplied to the connection port 13 communicated with the fresh air treatment section 101.

[0036] Furthermore, in this embodiment, the heat exchanger 42 adopts a finned heat exchanger, which operates as an evaporator during refrigeration and as a condenser during heating.

[0037] Further, in this embodiment, the indoor return air discharge module 50 includes a return air filtering unit 51 disposed in the return air input chamber 112 and an exhaust fan unit 52 disposed at the top of the exhaust chamber 114. When the new type of floor-standing fresh air unit operates with fresh air, the indoor return air is input from the connection port 13 communicating with the return air input chamber 112. After the indoor return air passes through the return air filtering unit 51 and the total heat exchanger 20 in sequence, with the operation of the exhaust fan unit 52, the air is exhausted from the connection port 13 communicating with the exhaust chamber 114.

[0038] Further, in this embodiment, the fresh air filtering unit 43 is formed by combining multiple filters, including but not limited to G4 filters, F8 filters, H10 filters, and H13 filters.

[0042] Further, in this embodiment, a floor mounting frame 15 is installed at the bottom of the housing 10 for floor mounting.

[0043] It can be understood that the usage method of a new type of floor-standing fresh air unit of the present utility model is as follows: When the new type of floor-standing fresh air unit operates with fresh air, the external valves on the external pipelines connected to the two connection ports 13 communicating with the fresh air input chamber 113 and the exhaust chamber 114 are opened, and the air valve 30 between the exhaust chamber 114 and the air inlet section 102 is closed. The outdoor fresh air and the indoor return air pass through the total heat exchanger 20 synchronously to recover the cold or heat in the room. Subsequently, the indoor return air is discharged outdoors, and the outdoor fresh air passes through the finned heat exchanger, is cooled or heated, and then sent indoors;

[0044] When the new type of floor-standing fresh air unit operates with return air, the external valves on the external pipelines connected to the two connection ports 13 communicating with the fresh air input chamber 113 and the exhaust chamber 114 are closed, and the air valve 30 between the exhaust chamber 114 and the air inlet section 102 is opened. Thus, in the case where the outdoor fresh air cannot enter the unit, the indoor return air can pass through the return air conveying channel of the total heat exchanger 20 and the air valve 30 in sequence, and then pass through the finned heat exchanger, be cooled or heated, and then sent back indoors;

[0045] In this way, the new type of floor-standing fresh air unit can not only realize the function of indoor and outdoor air circulation, but also realize the function of indoor return air circulation.

[0046] In summary, through the cooperation among the casing 10, the total heat exchanger 20, the air valve 30, the outdoor fresh air input module 40 and the indoor return air discharge module 50, the new type of floor-standing fresh air unit of the present utility model can not only realize the function of indoor and outdoor air circulation, but also realize the function of indoor return air circulation, with more diverse functions, and can be vertically docked from the connection port 13 at the top of the casing 10, without occupying the lateral space of the casing 10, making it more convenient to use.
