The fresh air unit 1 is an air treatment device, which mainly comprises a fresh air valve, a filter, a surface heat exchanger, a humidifier and a supply fan. The supply end of the fresh air unit 1 is connected with a supply main pipe 2, the air outlet end of the supply main pipe 2 extends into the application space 8 and is provided with a plurality of air outlets 21. The return air end of the fresh air unit 1 is connected with a return air main pipe 3, the return air main pipe 3 is connected in parallel with a plurality of return air branch pipes 5 through a first air distribution pipe 4, the return air branch pipes 5 extend into the application space 8 and are connected in parallel with a plurality of air pipes 7 through a second air distribution pipe 6, the return air inlets 71 of the air pipes 7 are arranged in the application space 8, and a plurality of return air inlets 71 are formed in the application space 8. The return air end of the fresh air unit 1 has a negative pressure, the air in the application space 8 is sucked into the air pipes 7 through the negative pressure suction force of the return air inlets 71 of the air pipes 7, the sucked air is collected into the corresponding return air branch pipes 5 after the second air distribution pipe 6 and finally enters the fresh air unit 1 through the first air distribution pipe 4 and the return air main pipe 3, the supply end of the fresh air unit 1 has a positive pressure, the air filtered and purified by the fresh air unit 1 is again transported into the application space 8 from the air outlets 21 of the supply main pipe 2, and the pressure difference between the positive pressure and the negative pressure is formed in the application space 8, so that the air in the application space 8 flows and the air circulation in the application space 8 is realized.

[0027] The application space 8 is an indoor environment, which can be a suite with a plurality of rooms or an open room (one open whole indoor space), and one application space 8 can be divided into a plurality of air exchange end spaces 81. Generally, a small-area open room or a room (such as a guest bedroom, a child's room, etc.) in a suite is a single air exchange end space 81, and a large-area open room or a room (such as a living room, a master bedroom, etc.) in a suite can also be divided into a plurality of air exchange end spaces 81. Each return air branch pipe 5 corresponds to an air exchange end space 81, the second air distribution pipe 6 is arranged at the adjacent position of the air exchange end space 81 (which can also be regarded as the entrance of the air exchange end space 81), and after one side of the pipe of each air pipe 7 is connected with the second air distribution pipe 6, the pipe body of the air pipe 7 is regularly arranged in the air exchange end space 81, and the other side of the pipe of each air pipe 7 (i.e. the return air inlet 71) is arranged at a position far away from the second air distribution pipe 6, that is, the return air inlets 71 of the air pipes 7 are collected at one position in the air exchange end space 81. Further, the return air inlets 71 of the air pipes 7 can be collected at two or more positions in the air exchange end space 81 according to the actual building structure of the air exchange end space 81. Preferably, when the return air inlets 71 of the air pipes 7 are collected at one position in the air exchange end space 81, the return air inlets 71 are collected at the position farthest away from the second air distribution pipe 6 (which can also be regarded as the end of the air exchange end space 81).

[0028] When the application space 8 is divided into multiple ventilation end spaces 81, and the air return ports 71 of each air pipe 7 are all arranged at the end of each ventilation end space 81, the air outlet 21 of the air supply main pipe 2 is arranged at the center of the entire application space 8, so that the distance between the air outlet 21 of the air supply main pipe 2 and the air return port 71 of each air pipe 7 is as same as possible, and at this time, the air outlet 21 of the air supply main pipe 2 is far away from the air return port of the air pipe 7, forming an air circulation path of air outlet in the middle and air suction around. When the area of the application space 8 is small, i.e. there is only one ventilation end space 81 in one application space 8, the air outlet 21 of the air supply main pipe 2 and the second air distribution row 6 are arranged at one side of the entrance of the ventilation end space 81, and the air return port 71 of the air pipe 7 is arranged at the other side of the end of the ventilation end space 81 (i.e. the innermost side of the ventilation end space 81), so that the air outlet 21 of the air supply main pipe 2 is farthest away from the air return port 71 of each air pipe 7, forming an air circulation path of air outlet on one side and air suction on the other side.

[0029] If the application space 8 is a two-room-one-living-room suite (such as Figure 1When the application space 8 is divided into four end spaces 81 (as shown in the figure), the fresh air handling unit 1 is arranged on the balcony outside the application space 8, the air outlet end of the air supply main pipe 2 extends from the ground to the inside of the application space 8, and two air outlets 21 are arranged in the central area of the application space 8, one of which is arranged in the central area of the living room, i.e. in the middle of the two end spaces 81 of the living room, and the other is arranged on the corridor outside the two rooms. Four air return branch pipes 5 extend from the ground to the inside of the application space 8, and four second air distribution devices 6 are arranged at the doorways of the two rooms and the adjacent areas of the two end spaces 81 of the living room. The air return port 71 of the air pipe 7 is arranged on the wall on the side farthest from the air outlet 21 in each end space 81, i.e. the distance between the second air distribution device 6 and the air return port 71 of the air pipe 7 is as far as possible, and each air pipe 7 crosses the entire end space 81 from the ground. Specifically, the air outlet 21 of the air supply main pipe 2 is arranged on the ground in the central area of the application space 8, and the air return port 71 of the air return main pipe 3 is arranged on the skirting of the wall on the side farthest from the air outlet 21, or on the ground below the wall. The air return ports 71 around the application space 8 suck the air in the rooms and the living room into the air pipe 7, the sucked air is collected into the first air distribution device 4 through the second air distribution device 6 and the corresponding air return branch pipe 5, and finally transported back to the air return end of the fresh air handling unit 1 through the air return main pipe 3. The sucked air is filtered and purified by the fresh air handling unit 1, and then transported again to the central area of the corridor of the rooms and the living room through the air supply main pipe 2 from the air supply end of the fresh air handling unit 1, completing the air circulation in the application space 8. Even if the doors of the rooms are closed, air circulation can still be achieved through the air gap between the doors.

[0030] Further, the air supply amount of each air outlet 21 on the air supply main pipe 2 and the air return amount of the air return port 71 on the air pipe 7 can be freely adjusted. Preferably, during installation, the air supply amount of each air outlet 21 on the air supply main pipe 2 is adjusted to be uniform, and the air return amount of all air return ports 71 of the air pipes 7 in a corresponding end space 81 is adjusted to be uniform through the second air distribution device 6, to ensure that air continuously flows in each air pipe 7.

[0031] Further, after adjusting the air return amount of all air return ports 71 of the air pipes 7 in a corresponding end space 81 to be uniform through the second air distribution device 6 during installation, the second air distribution device 6 is constructed in a concealed manner.

[0032] Further, the first gas distribution row 4 is provided with a plurality of valves, the valves are used for controlling the opening and closing state of the corresponding return air branch pipes 5, when the user only needs to perform air circulation on a certain air exchange end space 81, only needs to control the corresponding valve on the first gas distribution row 4, adjusts the return air branch pipe 5 corresponding to the air exchange end space 81 to the open state, and adjusts the remaining return air branch pipes 5 to the closed state, so that the air circulation function of any air exchange end space 81 can be realized. Preferably, the valve on the first gas distribution row 4 is an electric valve.

[0033] The application can be used as an air circulation system in the "five constant system", combined with a heat pump main system and a heat exchange platform. The application can be combined with the double-mode heat exchange system disclosed in the patent with the application number 2024217007030, which combines thermal radiation and thermal convection. The air circulation system and the heat exchange platform are used in structure, so that the air circulation system becomes part of the heat exchange pipeline, which is used to supplement the insufficient radiation heat exchange cooling capacity. At the same time, the overall structure of the five constant system composed of the heat pump main system, the heat exchange platform and the air circulation system is more compact, occupies less space, and is more in line with user needs.

[0034] Specifically, the heat pump main system includes a cold and heat source, the cold and heat source is connected with a heat exchange pipeline for heat exchange in a heat exchange space, the heat exchange pipeline includes a circulating pump for providing power for heat exchange, and a water pipeline is arranged in the heat exchange space. The air pipe 7 is arranged above the water pipeline along the arrangement path of the water pipeline and abuts against the water pipeline. The heat exchange pipeline transfers heat to the heat exchange space in the form of thermal radiation, and the air pipe 7 is arranged above the water pipeline in the same position and overlaps the water pipeline to continuously supply air to the heat exchange space. Part of the heat in the medium water is transferred to the continuously flowing gas in the air pipe 7 in the form of thermal radiation, and the gas is circulated and transported in the heat exchange space by the fresh air handling unit 1 to transfer heat to the heat exchange space in the form of thermal convection. That is, the heat exchange space is heated by the two heat transfer modes of thermal radiation and thermal convection at the same time, which accelerates the heat exchange rate in the heat exchange space, shortens the required heat exchange time, achieves the effect of rapid heat exchange, and improves the user experience. On the other hand, when cooling the heat exchange space, the air transported by the air pipe 7 circulates the cooling capacity of the refrigerant in the heat exchange space, supplements the insufficient radiation heat exchange cooling capacity, and accelerates the cooling of the heat exchange space. At the same time, the air pipe 7 separates the water pipeline from the ground, reduces the direct cooling capacity exchange between the refrigerant and the ground, and keeps the ground dry, which meets the living requirements.

[0035] Although the application has been described by using the above preferred embodiments, it is not intended to limit the protection scope of the application, and any person skilled in the art can make various changes and modifications to the above embodiments without departing from the spirit and scope of the application.
