[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Reference Figure 1-2 The present invention provides a combined indoor air treatment system, a shell 1, which has a fresh air channel and a dirty air channel 4 that are not connected to each other and are arranged side by side. The fresh air channel and the dirty air channel 4 exchange air heat through a heat exchanger 5, wherein the heat exchanger 5 is used to separate the fresh air channel into an air inlet channel 2 and an air supply channel 3 that are connected to each other, the fresh air port 23 of the air inlet channel 2 and the air supply port 33 of the air supply channel 3 are located on the same side wall of the shell 1, and the heat exchanger 5 is used to separate the dirty air channel 4 into a return air channel 41 and an exhaust air channel 42 that are connected to each other, the return air port 43 of the return air channel 41 and the exhaust air port 44 of the exhaust air channel 42 are located on two side walls of the shell 1 that are opposite to each other; a surface cooler component is arranged in the air supply channel 3 and the return air channel 41; a monitoring component has a plurality of monitoring terminals, and the monitoring terminals are used to monitor the temperature and humidity in the air inlet channel 2, the air supply channel 3, the exhaust channel 42, and the return air channel 41.

[0022] It can be understood that the outdoor fresh air is sent into the room after being filtered through the fresh air channel, and the indoor return air is sent to the outside after being filtered through the dirty air channel 4. During the process of fresh air entering and dirty air being discharged, heat exchange between fresh air and dirty air is achieved through the heat exchanger 5.

[0023] Among them, the fresh air channel includes an air inlet channel 2 and an air supply channel 3, and the fresh air outlet 23 and the air supply channel 3 are on one side wall of the shell. At the same time, the air inlet channel 2 and the air supply channel 3 are arranged in two layers, and the air inlet channel 2 and the air supply channel 3 cooperate with the return air channel 41 and the exhaust channel 42 to form a three-layer structure in the shell 1.

[0024] For further optimization, refer to Figure 1 The air inlet channel 2 is divided into a first channel 21 and a second channel 22 arranged side by side, the first channel 21 is connected to a fresh air outlet 23 connected to the housing 1, and the second channel 22 is used to connect the first channel 21 and the heat exchanger 5; An air supply fan 24 is provided in the second channel 22 , and an electric fresh air valve 25 is provided on the fresh air outlet 23 .

[0025] It can be understood that the air inlet channel 2 is divided into a first channel 21 and a second channel 22 by a sheet metal partition plate. The first channel 21 and the second channel 22 are connected end to end and arranged side by side. The outside fresh air is delivered into the first channel 21 through the fresh air outlet 23, moves in the first channel 21 in the direction away from the air supply outlet 33, and returns to the second channel 22 when the fresh air moves to the inner wall of the shell, and enters the heat exchanger 5 through the second channel 22 for heat exchange and then enters the air supply channel 3.

[0026] An air supply fan 24 for driving the movement of fresh air is arranged in the second channel 22. At the same time, a controllably driven electric fresh air valve 25 is arranged on the fresh air outlet 23. The electric fresh air valve 25 is used to control the opening and closing size of the fresh air outlet 23, thereby controlling the flow rate of fresh air entering the first channel 21.

[0027] For further optimization, refer to Figure 1 The air supply channel 3 is divided into a third channel 31 and a fourth channel 32 arranged side by side. The third channel 31 is connected to an air supply port 33 connected to the shell 1 , and the fourth channel 32 is used to connect the third channel 31 and the heat exchanger 5 .

[0028] It can be understood that the outside fresh air enters the fourth channel 32 after heat exchange through the heat exchanger 5, and the air moves in the fourth channel 32 in the direction away from the fresh air outlet 23. When the air moves to the other side wall of the shell 1, it returns to enter the third channel 31, enters the air supply outlet 33 through the third channel 31 and is discharged into the room.

[0029] In the above structure, the air inlet channel 2 and the air supply channel 3 are set as a two-layer structure, which can make the movement distance of the outside fresh air in the shell 1 longer, thereby better realizing the filtering, heat exchange, heating, cooling and other operations in the shell 1. For further optimization, refer to Figure 1 A fresh air fan 45 is provided in the exhaust passage 42 , and an electric exhaust valve 46 is provided on the exhaust port 44 .

[0030] Specifically, under the action of the fresh air fan 45, the indoor return air enters the return air duct 41 through the return air port 43, and the return air enters the exhaust duct 42 through the heat exchanger 5. At the same time, the return air exchanges heat with the external fresh air in the heat exchanger 5, and finally the return air that has completed the heat exchange is discharged outdoors through the exhaust port 44.

[0031] In one embodiment of the present invention, the electric fresh air valve 25 and the electric exhaust valve 46 are preferably wing-type windproof valves.

[0032] In one embodiment of the present invention, the side panel of the shell 1 and the partitions used to separate the fresh air channel and the dirty air channel, the first channel 21 and the second channel 22, and the third channel 31 and the fourth channel 32 are preferably made of 50 mm thick double-sided metal plates, and filled with polyurethane foam material with a fire protection grade of B2 in the middle.

[0033] For further optimization, refer to Figure 1 The cooler assembly includes a fresh air compensation cooler 6 and an antifreeze cooler 7. The fresh air compensation cooler 6 is arranged in the fourth channel 32. The fresh air compensation cooler 6 is used to heat the air in the air supply channel 3. The antifreeze cooler 7 is located in the return air channel 41.

[0034] It can be understood that the fresh air compensation cooler 6 is used to compensate the temperature of the fresh air entering the room. In summer and winter, the fresh air entering the room is temperature-adjusted to the supply air temperature of 23°C. At the same time, the fresh air compensation cooler 6 should be externally connected to an analog regulating water valve. At the same time, the analog regulating water valve is heavy, and the analog regulating water valve needs to be supported during use to avoid damage to the water inlet pipe of the fresh air compensation cooler 6.

[0035] The antifreeze cooler 7 is used to heat the indoor return air. In winter, the indoor return air that is about to enter the heat exchanger 5 is heated up, which has the effect of antifreeze protection for the heat exchanger 5 at low temperatures. At the same time, the antifreeze cooler 7 should be an external switch to adjust the water valve.

[0036] For further optimization, refer to Figure 1 A first primary filter 81 and a medium filter 82 are disposed in the first channel 21, and the medium filter 82 is located on a side of the primary filter away from the fresh air outlet 23; A high efficiency filter 83 is disposed in the third channel 31 , a second primary filter 84 is disposed in the return air channel 41 , and the second primary filter 84 is located on a side of the antifreeze condenser 7 close to the return air port 43 .

[0037] It can be understood that in the fresh air channel, a first primary filter 81, a medium efficiency filter 82, and a high efficiency filter 83 are sequentially arranged along the direction of fresh air being sent into the room, and the fresh air is filtered through three layers before being sent into the room.

[0038] Specifically, the first primary filter 81 is a primary plate filter (G4 grade), the medium filter 82 is a medium bag filter (F6 grade), and the high efficiency filter 83 is a high efficiency stack filter (H11 grade).

[0039] At the same time, the second primary filter 84 is used to filter the indoor return air to remove large particles of impurities or debris in the indoor return air to prevent large particles of impurities or debris from entering the heat exchanger 5. The second primary filter 84 has the same structure as the first primary filter 81.

[0040] For further optimization, refer to Figure 2 A first differential pressure switch 85 is provided at the air inlet end of the first primary filter 81 and the air outlet end of the medium efficiency filter 82 , and a second differential pressure switch 86 is provided at the air inlet end and the air outlet end of the high efficiency filter 83 .

[0041] It can be understood that the first differential pressure switch 85 is used to monitor the differential pressure between the air inlet end of the first primary filter 81 and the air outlet end of the medium efficiency filter 82, and the second differential pressure switch 86 is used to monitor the differential pressure between the air inlet end and the air outlet end of the high efficiency filter 83. By using differential pressure control alarm and displaying it outside the housing 1, the above-mentioned filter structure can be monitored, and the blockage degree of the filter structure can be obtained through external observation.

[0042] For further optimization, refer to Figure 2 The monitoring end includes an air supply sensor 91 disposed in the first channel 21, the air supply sensor 91 is close to the fresh air outlet 23, a fresh air sensor 92 disposed in the third channel 31, the fresh air sensor 92 is located on the side of the high efficiency filter 83 away from the air supply outlet 33, and a compensation cooler sensor 96 is disposed in the fourth channel 32, and the compensation cooler sensor 96 is located on the side of the fresh air compensation cooler 6 close to the heat exchanger 5; A first return air sensor 93 is arranged in the return air duct 41, and the first return air sensor 93 is located on the side of the antifreeze cooler 7 close to the heat exchanger 5. A second return air sensor 94 is arranged on the return air outlet 43. An exhaust air sensor 95 is arranged in the exhaust air duct 42, and the exhaust air sensor 95 is located on the side of the fresh air fan 45 close to the exhaust air outlet 44.

[0043] It can be understood that the air supply sensor 91 is used to monitor the temperature and humidity of the external fresh air entering the shell 1 through the fresh air outlet 23; the compensating condenser sensor 96 is used to monitor the temperature and humidity of the fresh air passing through the heat exchanger 5 and about to enter the fresh air compensating condenser 6; the fresh air sensor 92 is used to monitor the temperature and humidity of the fresh air entering the room after passing through the fresh air compensating condenser 6.

[0044] The second return air sensor 94 is used to monitor the temperature, humidity, PM2.5, and CO2 of the return air entering the return air outlet 43 indoors; the first return air sensor 93 is used to monitor the temperature and humidity of the return air passing through the antifreeze cooler 7 and about to enter the heat exchanger 5.

[0045] Specifically, the supply air sensor 91, the fresh air sensor 92, the first return air sensor 93, the exhaust air sensor 95, and the compensating cooler sensor 96 are all sensors with the function of monitoring the temperature and humidity of the air, and the second return air sensor 94 is a sensor with the function of monitoring the temperature, humidity, PM2.5, and CO2 of the return air.

[0046] Further, see Figure 2 A photoelectric sensor 97 is provided on the heat exchanger 5. The photoelectric sensor 97 is used to alarm the heat exchanger 5. The photoelectric sensor 97 monitors the heat exchanger 5 through radiation temperature measurement. When the temperature of the heat exchanger 5 is too low and there is ice, the heat exchanger 5 is alarmed through feedback from the photoelectric sensor 97.

[0047] For further optimization, refer to Figure 1 Silence boxes 10 are provided at the first channel 21 near the fresh air inlet 23 , at the third channel 31 near the air supply outlet 33 , at the return air channel 41 near the return air inlet 43 , and at the exhaust air channel 42 near the exhaust air outlet 44 .

[0048] It can be understood that at the positions where the fresh air inlet 23, the air supply outlet 33, the return air outlet 43, and the exhaust outlet 44 are connected to the shell 1, a sound-absorbing sponge is pasted on the inner wall of the shell 1 to form a sound-absorbing box 10 to achieve a sound-absorbing effect.

[0049] According to a further optimization scheme, the heat exchanger 5 is a full heat exchange wheel.

[0050] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
