[0002] With the continuous development of society, people's living standards have been greatly improved, and people are paying more and more attention to air quality. Fresh air air conditioning units have come into being, bringing great convenience to people's lives. Fresh air air conditioning units are an effective air purification device. On the one hand, they exhaust the dirty air indoors to the outside, and on the other hand, they filter and heat and humidify the fresh air outdoors before inputting it into the room.

[0003] In the publication number CN111023331A, a combined rotary heat recovery fresh air air-conditioning unit is proposed, including a shell, on which are provided a return air inlet, an exhaust air outlet, a fresh air inlet and an air supply inlet, and a group of functional sections that cooperate with each other are provided in the shell, including: a fresh air filter section, a high-efficiency rotary wheel section, a cooling and heating surface cold section, a humidifier section, a silencer section, an air supply section, an exhaust air filter section, an exhaust section, and a bypass air valve is provided between the exhaust air filter section and the cooling and heating surface cold section; the functional sections cooperate to form a fresh air heat recovery functional group, a fresh air heat recovery air conditioning functional group and an internal circulation functional group.

[0004] The fresh air air conditioning unit in the above patent adds a high-efficiency rotor to exchange heat between indoor and outdoor air, thereby avoiding excessive heat loss of the discharged indoor air, increasing the heat of the introduced fresh air, and achieving energy-saving effects. However, due to the addition of a high-efficiency rotor, the operation of the high-efficiency rotor itself consumes electricity, so the energy consumption of the fresh air air conditioning unit itself increases, and the overall energy-saving effect is not very good. Summary of the invention

[0005] To this end, the technical problem to be solved by the present invention is to overcome the problem that the structure of the fresh air air conditioning unit in the prior art is unreasonable, resulting in high energy consumption and not meeting the energy-saving needs.

[0006] To solve the above technical problems, the present invention provides a full-effect air-conditioning unit with a single fan, comprising: a box body, an intermediate partition plate is provided inside the box body, the intermediate partition plate divides the inside of the box body into two independent first and second cavities, the upper end of the first cavity is provided with an air supply port, and the lower end of the first cavity is provided with an air exhaust port, the upper end of the second cavity is provided with a return air port, and the lower end of the second cavity is provided with a fresh air inlet port; an air valve, which is installed on the intermediate partition plate, and the wind entering the second cavity through the return air port enters the first cavity through the air valve; a plate-type heat recovery device, which is arranged at the lower end of the intermediate partition plate, and the wind entering the fresh air inlet port enters the first cavity through the plate-type heat recovery device; a fan, which is arranged in the first cavity, and the fan is used to provide flow force for the wind in the air valve and the plate-type heat recovery device; an air duct, one end of which is installed on the intermediate partition plate, and the other end of the air duct is connected to the plate-type heat recovery device, and the wind in the air duct and the wind entering the fresh air inlet port exchange heat at the plate-type heat recovery device. The single-fan full-effect air conditioning unit described in the present invention is suitable for high-end apartment residences, providing a comfortable, energy-saving and healthy indoor air environment. The outdoor air is initially filtered through a fresh air filter, and then further processed through a fresh air pretreatment device. The treated fresh air is mixed with the return air and sent into the room through a fan. This system ensures the cleanliness and comfort of the indoor air through multi-stage filtration and heat exchange. The indoor air enters the unit through the return air port, is processed again and then sent back to the room. At the same time, part of the return air passes through the exhaust duct, recovers energy through a heat recovery device, and then is discharged outdoors. This system is designed to provide efficient air treatment and energy recovery, ensuring indoor air quality while saving energy.

[0007] In one embodiment of the present invention, a quantitative air valve is provided on the air duct, and the quantitative air valve connects or cuts off the air duct and the second cavity. When the quantitative air valve is opened, the air in the second cavity enters the air duct.
