In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0054] The basic function of the air handling device of the present application is mainly to regulate the temperature of the air, such as a refrigerant fresh air blower, and its working principle is: to perform a refrigeration cycle by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0055] The compressor compresses the refrigerant gas in a low temperature and low pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process. The expansion valve expands the liquid phase refrigerant in a high temperature and high pressure state condensed in the condenser into a low pressure liquid phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low temperature and low pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the whole cycle, the air handling unit can adjust the temperature of the indoor space.

[0056] The outdoor unit of the air handling device refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air handling device includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0057] The specific structure of the air treatment device provided in the embodiment of the present application is described in detail below.

[0058] Figure 1 This is a view of the internal structure of the air handling device provided in the embodiment of the present application. Figure 2A side internal view of an air treatment device provided in an embodiment of the present application, Figure 3 A side view of an air treatment device provided in an embodiment of the present application.

[0059] like Figures 1 to 3 As shown, an embodiment of the present application provides an air treatment device, which includes a housing 100 and a heat recovery device 200. The heat recovery device 200 is arranged at the back of the housing 100. The housing 100 has an air inlet channel 110 and an air outlet channel 120. When the air treatment device turns on the fresh air function, outdoor air enters the room through the air inlet channel 110, and the indoor air is discharged to the outside through the air outlet channel 120.

[0060] The air inlet channel 110 has an air inlet 111 and an air outlet 112 . The air inlet 111 is connected to the outdoor space, and the air outlet 112 is connected to the indoor space. Outdoor air enters the air inlet channel 110 from the air inlet 111 and enters the indoor space from the air outlet 112 .

[0061] The exhaust passage 120 has a return air port 121 and an exhaust air port 122. The return air port 121 is connected to the indoor space, and the exhaust air port 122 is connected to the outdoor space. The indoor air enters the exhaust passage 120 through the return air port 121 and is discharged to the outdoors from the exhaust air port 122. The return air port 121 and the air outlet 112 are both connected to the indoor space. The return air port 121 and the air outlet 112 are located on different sides of the housing 100. Therefore, the airflow flowing in from the return air port 121 and the airflow discharged from the air outlet 112 can be distributed on different sides of the housing 100, thereby avoiding interference between the airflow of the supply air and the airflow of the return air.

[0062] It is understandable that the heat recovery device 200 is located at the intersection of the exhaust channel 120 and the inlet channel 110, and the airflow of the inlet channel 110 and the airflow of the exhaust channel 120 will flow through the heat recovery device 200. The heat recovery device 200 is configured to allow the airflow of the inlet channel 110 and the airflow of the exhaust channel 120 to exchange heat.

[0063] It should be noted that the heat recovery device 200 has multiple airflow channels, and the airflow of the air inlet channel 110 and the airflow of the exhaust channel 120 flow through different airflow channels respectively, and will not cause crosstalk. In addition, the airflow of the air inlet channel 110 and the air flow of the exhaust channel 120 can be heat-conducted through the shell wall of the heat recovery device 200, thereby realizing heat exchange between the two airflows. In this way, by designing the layout of the air inlet channel 110 and the exhaust channel 120, the heat recovery device 200 is used to perform heat exchange on the airflow of the air inlet channel 110 and the exhaust channel 120, so as to improve energy utilization and reduce energy consumption.

[0064] [case]

[0065] In the embodiment of the present application, the projection shape of the housing 100 can be a square, and the air inlet 111, the air outlet 112, the return air outlet 121 and the exhaust air outlet 122 can all be arranged on the side wall of the housing 100. The shape of the housing 100 can also be circular, elliptical, trapezoidal or other polygonal, and the embodiment of the present application does not limit the specific shape of the housing 100.

[0066] Please continue to refer to Figures 1 to 3 In some embodiments, the air inlet channel 110 may include a first ventilation cavity 101 and a second ventilation cavity 102, and the first ventilation cavity 101 and the second ventilation cavity 102 are connected through the heat recovery device 200. The air inlet 111 is connected to the first ventilation cavity 101; the air outlet 112 is connected to the second ventilation cavity 102.

[0067] It can be understood that after the outdoor air enters from the air inlet 111, it first flows into the first ventilation cavity 101, flows through the first ventilation cavity 101 and then enters the heat recovery device 200, flows out of the heat recovery device 200, enters the second ventilation cavity 102, and finally flows from the second ventilation cavity 102 through the air outlet 112 into the indoor space.

[0068] In some embodiments, the exhaust passage 120 may include a third ventilation cavity 103 and a fourth ventilation cavity 104, which are connected via a heat recovery device 200. The return air port 121 is connected to the third ventilation cavity 103; the exhaust air port 122 is connected to the fourth ventilation cavity 104.

[0069] It can be understood that after the indoor air enters from the return air outlet 121, it flows into the third ventilation chamber 103, flows through the third ventilation chamber 103 and enters the heat recovery device 200, flows out of the heat recovery device 200, enters the fourth ventilation chamber 104, and finally flows from the fourth ventilation chamber 104 through the exhaust outlet 122 to the outdoor space.

[0070] In some embodiments, the first ventilation cavity 101, the fourth ventilation cavity 104, the second ventilation cavity 102, and the third ventilation cavity 103 are arranged in sequence around the circumference of the heat recovery device 200, that is, the heat recovery device 200 is located in the middle of the first ventilation cavity 101, the fourth ventilation cavity 104, the second ventilation cavity 102, and the third ventilation cavity 103.

[0071] Exemplarily, the shell 100 may have four corners, and the four corners are paired in pairs to form two pairs of corners. The first ventilation cavity 101 and the second ventilation cavity 102 are arranged corresponding to one pair of corners, and the third ventilation cavity 103 and the fourth ventilation cavity 104 are arranged corresponding to the other pair of corners. From the circumferential order around the heat recovery device 200, the fourth ventilation cavity 104 is located between the first ventilation cavity 101 and the second ventilation cavity 102, the first ventilation cavity 101 is located between the third ventilation cavity 103 and the fourth ventilation cavity 104, the third ventilation cavity 103 is located between the first ventilation cavity 101 and the second ventilation cavity 102, and the second ventilation cavity 102 is located between the third ventilation cavity 103 and the fourth ventilation cavity 104.

[0072] It should be noted that since both the air inlet 111 and the air outlet 122 need to be connected to the outdoor space, when the air treatment device is installed, the air inlet 111 and the air outlet 122 can be installed and connected to the pipe, and connected to the outdoor space through the pipe, so that the installation space of the air treatment device in the room is not restricted.

[0073] Exemplarily, the return air vent 121 and the air outlet 112 may be located on two adjacent sides of the housing 100, thereby facilitating the layout of the air inlet channel 110 and the air outlet channel 120. For example, the side where the return air vent 121 is located and the side where the air outlet 112 is located may be perpendicular to each other.

[0074] In some embodiments, the housing 100 may include a base 130 and a side wall 140 , the heat recovery device 200 may be installed on the base 130 , and the side wall 140 and the enclosure form an inner space of the housing 100 .

[0075] It should be noted that the material of the shell 100 can be metal or alloy such as iron, aluminum, etc., or the material of the shell 100 can be plastic, or a combination of multiple materials, which is not specifically limited in the embodiments of the present application.

[0076] [Heat recovery device]

[0077] The heat recovery device 200 provided in the embodiment of the present application can realize heat exchange between the air inlet channel 110 and the air exhaust channel 120. The specific forms of heat exchange performed by the heat recovery device 200 include but are not limited to heat conduction, heat radiation, heat convection, etc., and the embodiment of the present application does not make specific limitations on this.

[0078] Please continue to refer to Figures 1 to 3In some embodiments, the heat recovery device 200 may be a plate-type heat recovery structure. The heat recovery device 200 may include a plurality of heat exchange plates. The plurality of heat exchange plates are spaced apart from each other and form a plurality of channels between each other. The airflows of the air inlet channel 110 and the air exhaust channel 120 are connected to different channels. When the airflows of the air inlet channel 110 and the air exhaust channel 120 flow through both sides of the heat exchange plates respectively, heat exchange may be performed through the heat exchange plates.

[0079] It can be understood that the first ventilation cavity 101, the fourth ventilation cavity 104, the second ventilation cavity 102 and the third ventilation cavity 103 are arranged around the heat recovery device 200. The projections of the first ventilation cavity 101, the fourth ventilation cavity 104, the second ventilation cavity 102 and the third ventilation cavity 103 in the direction perpendicular to the base 130 do not overlap each other. In this way, the air inlet channel 110 and the air exhaust channel 120 only occupy one layer of space in the housing 100, that is, a single-layer ventilation structure is formed, so that the volume of the cavity processing device is relatively small, so that the installation occupies a small space.

[0080] [Partition]

[0081] Please continue to refer to Figures 1 to 3 In some embodiments, the air handling device may further include a partition 300 connected between the heat recovery device 200 and the inner wall of the housing 100. The partition 300, the heat recovery device 200 and the inner wall of the housing 100 are jointly formed to form an air inlet channel 110 and an air outlet channel 120.

[0082] It can be understood that the partition plate 300 is disposed between the air inlet channel 110 and the air outlet channel 120 , and the partition plate 300 guides the flow of air in the air inlet channel 110 and the air outlet channel 120 .

[0083] The first end of the partition 300 is sealed to the inner wall of the shell 100, and the second end of the partition 300 is sealed to the outer wall of the heat recovery device 200. For example, elastic seals such as rubber can be provided between the partition 300 and the inner wall of the shell 100, and between the partition 300 and the heat recovery device 200, or they can be sealed by sealant or connected by welding to ensure good sealing.

[0084] It should be noted that the height of the partition 300 can match the height of the shell 100, and an upper cover can be provided on the side of the partition 300 away from the base 130, and the upper cover abuts against the upper edge of the partition 300 to ensure sealing.

[0085] In some embodiments, the partition 300 may include a first partition, a second partition, a third partition and a fourth partition, wherein the first partition is arranged between the first ventilation cavity 101 and the fourth ventilation cavity 104, the second partition is arranged between the fourth ventilation cavity 104 and the second ventilation cavity 102, the third partition is arranged between the second ventilation cavity 102 and the third ventilation cavity 103, and the fourth partition is arranged between the third ventilation cavity 103 and the first ventilation cavity 101.

[0086] Exemplarily, the materials of the first partition, the second partition, the third partition and the fourth partition can all be metals or alloys such as iron and aluminum, or can be plastic materials. The embodiment of the present application does not limit the specific material type of the partition 300.

[0087] In some embodiments, there may be a plurality of air outlets 112 , and the plurality of air outlets 112 may be disposed on the same side of the housing 100 , and the plurality of air outlets 112 may be arranged at intervals, thereby improving the efficiency of the jet air outlet.

[0088] Exemplarily, the number of the air outlets 112 may be two, three or more, and the shape of the air outlets 112 may be circular, square or other shapes, which is not limited in the embodiments of the present application.

[0089] In the embodiment of the present application, different fans can be used to generate airflow in the air inlet channel 110 and the air exhaust channel 120 respectively, and corresponding temperature regulation-related component units can be set, which is described in detail below.

[0090] In some embodiments, the air treatment device may further include a first fan 400 and a second fan 500. The first fan 400 is located in the air inlet channel 110 and is disposed corresponding to the air inlet 111, and the second fan 500 is located in the air outlet channel 120 and is disposed corresponding to the air outlet 122.

[0091] It is understandable that both the first fan 400 and the second fan 500 can be controlled by the controller of the air handling device, and the first fan 400 can work alone, or the first fan 400 and the second fan 500 can work simultaneously. When the first fan 400 works alone, outdoor air is only sent into the room through the air inlet channel 110. When the first fan 400 and the second fan 500 work simultaneously, while sending air into the indoor space through the air inlet channel 110, the indoor air can be discharged through the exhaust channel 120, thereby increasing the speed of indoor air improvement.

[0092] It should be noted that in the embodiment of the present application, the air inlet 111 and the air outlet 122 can both be connected to the outdoor space through a pipe, or one of them can be connected to the outdoor space through a pipe, and the air inlet 111 and the air outlet 122 can be located on the same side of the shell 100, thereby facilitating the layout of the pipe outside the shell 100.

[0093] In some embodiments, the air handling device may further include a heat exchanger 600, which is disposed corresponding to the air inlet 111. The heat exchanger 600 is used to perform heat exchange with the airflow flowing through the air inlet channel 110, thereby increasing or decreasing the temperature of the airflow in the air inlet channel 110 to achieve a cooling or heating function.

[0094] The heat exchanger 600 has a water inlet 610 and a water outlet 620, and the water inlet 610 and the water outlet 620 are located on the same side of the housing 100, so that the heat exchanger 600 is connected to the heat exchange unit of the outdoor unit so that the refrigerant can circulate. The water inlet 610 and the water outlet 620 are arranged side by side on the same side of the housing 100, which can facilitate the layout and connection of the pipeline and avoid interference between the pipeline and other components or external objects during installation.

[0095] Exemplarily, the heat exchanger 600 may be a surface cooler. When the air handling device performs cooling and heating, the heat exchanger may function as a condenser and an evaporator, respectively, which will not be described in detail here.

[0096] In the embodiment of the present application, in order to ensure the quality of air entering the room and prevent turbid air from polluting the outdoor environment, the airflow flowing into the air inlet channel 110 and the air exhaust channel 120 can be filtered by a filter unit.

[0097] In some embodiments, the air treatment device may further include a first filter 700 and a second filter 800, wherein the first filter 700 is disposed at the air inlet 111, and the second filter 800 is disposed at the air return port 121. The first filter 700 may filter the airflow from the outside into the room, and absorb dust and impurities in the outside air to ensure the freshness of the air flowing through the room. The second filter 800 may filter the airflow discharged from the room to the outside, and absorb solid particles and grease in the air such as oil smoke and cigarettes, so as to avoid polluting the outside air.

[0098] Exemplarily, both the first filter 700 and the second filter 800 may be plate filters, and the first filter 700 may be installed and cover the air inlet 111 to ensure that the airflow flowing into the air inlet channel 110 passes through the first filter 700, and the projection shape of the first filter 700 in the air inlet direction may match the shape of the air inlet 111. The second filter 800 may be installed and cover the return air outlet 121 to ensure that the airflow entering the exhaust channel 120 passes through the second filter 800, and the projection shape of the second filter 800 in the air inlet direction may match the shape of the return air outlet 121.

[0099] In addition, it should be noted that a mounting portion may be provided at each corner of the shell 100, and a hanging hole may be opened on the mounting portion. When the air treatment device is installed indoors, it can be led through the hanging hole to cooperate with the indoor ceiling, wherein the base 130 of the shell 100 can face the indoor space.

[0100] The air treatment device provided in the embodiment of the present application includes a shell and a heat recovery device, the shell has an air inlet channel and an exhaust channel; the air inlet channel has an air inlet and an air outlet; the exhaust channel has a return air outlet and an exhaust outlet, and the return air outlet and the air inlet are located on different sides of the shell; the heat recovery device is arranged in the shell, and the heat recovery device is located at the intersection of the exhaust channel and the air inlet channel; the heat recovery device is configured to enable the airflow of the air inlet channel and the airflow of the exhaust channel to exchange heat, thereby improving energy utilization and reducing energy consumption. In addition, interference between the supply airflow and the return airflow can be avoided.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
