Description

Technical Field

[0001] The invention belongs to the technical field of air conditioning, and in particular relates to an integrated air conditioner. Background Art

[0002] With the development of computer technology and new energy technology, the market for container energy storage, small data rooms, and data center cooling is also growing. These places require temperatures to be within a reasonable range, while also keeping the air clean. The working principle of the fresh air system is to use a powerful fan to draw in outdoor air, filter it, and then transport it into the room. At the same time, a slightly positive pressure environment is created indoors (the pressure is generally 0-50Pa higher than the external environment), which expels the originally polluted air outdoors and helps prevent pollutants from entering the room through door and window gaps. For structures, it is impossible to achieve absolute sealing (no leakage or penetration). By adjusting the air supply and exhaust volume of the room (area), a stable positive or negative pressure in the room (area) can be created.

[0003] Conventional fan cooling systems have poor heat dissipation and easily introduce dust, moisture, and other gaseous debris from the outside air into the cabinet. Containerized energy storage systems and small data centers require dedicated air conditioners to maintain temperature control within the enclosed battery compartment or room. Temperature significantly impacts battery safety and lifespan, and data centers within the room also require excellent temperature control. Integrated cabinet air conditioners are self-contained units that can typically be installed directly on the container or energy storage cabinet's housing or door, either embedded or wall-mounted. The integration of the indoor and outdoor units facilitates installation and minimizes space.

[0004] At present, the existing technology meets the micro-positive pressure function and air conditioning cooling function by installing a fresh air fan and an integrated cabinet air conditioner at the same time. This solution has two sets of units, which is troublesome to install. There is also a technical solution that uses the fresh air fan and the cabinet air conditioner as a whole to save installation space, but it is necessary to add an additional positive pressure fan to the current cabinet air conditioner, thereby increasing the cost of the cabinet air conditioner; or, by installing a fresh air baffle or other similar air valve structure on the cabinet air conditioner partition to achieve the switching of the fresh air function, but it is necessary to add an air valve structure, and the fresh air (hot air) and cold air are mixed into the temperature control space, and the temperature in the temperature control space fluctuates greatly. Summary of the Invention

[0005] Therefore, the present invention provides an integrated air conditioner that can overcome the disadvantage in the related art that fresh air and cold air are mixed and then enter the temperature-controlled space, causing large temperature fluctuations.

[0006] In order to solve the above problems, the present invention provides an integrated air conditioner, including a shell, wherein a partition component is provided in the shell, and the partition component divides the internal space of the shell into an indoor space and an outdoor space that are independent of each other. The shell also has an air induced passage, the air inlet of the air induced passage is connected to the outdoor space, and the air outlet of the air induced passage is connected to the indoor space. An indoor heat exchanger is provided in the indoor space, and the air outlet of the air induced passage is located on the air inlet side of the indoor heat exchanger.

[0007] In some embodiments, the partition assembly includes a water receiving pan, which is located at the bottom of the indoor heat exchanger. The air induced passage includes an air induced pipe, which runs through the upper and lower sides of the water receiving pan.

[0008] In some embodiments, the water receiving tray has a water storage wall, and the height of the air duct in the water receiving space of the water receiving tray is not lower than the height of the water storage wall.

[0009] In some embodiments, the partition assembly further includes a partition, one end of which is connected to the water receiving tray.

[0010] In some embodiments, a flow regulating structure is provided at the outlet of the air duct.

[0011] In some embodiments, the flow regulating structure includes a flow regulating valve, and the opening of the flow regulating valve can be adjusted according to the pressure difference between the indoor space and the outdoor space.

[0012] In some embodiments, a filter component is provided at the air inlet of the air duct.

[0013] In some embodiments, an indoor fan is provided in the indoor space.

[0014] In some embodiments, the integrated air conditioner is a slightly positive pressure cabinet air conditioner.

[0015] The present invention provides an integrated air conditioner, which guides the air flow in the outdoor space to the indoor space through an air induced channel, thereby increasing the total amount of gas in the temperature-controlled space, and further achieving the purpose of micro-positive pressure adjustment of the temperature-controlled space. At the same time, the air outlet of the air induced channel is arranged on the air inlet side of the indoor heat exchanger, so that the air flow (hot air) introduced from the outdoor can be sent to the temperature-controlled space after heat exchange with the return air flow (cold air) from the indoor side and the indoor heat exchanger, effectively preventing the temperature fluctuation of the temperature-controlled space caused by the air flow introduced during the micro-positive pressure adjustment process, and the temperature of the temperature-controlled space is more stable.

[0021] See also Figures 1 to 3As shown, according to an embodiment of the present invention, an integrated air conditioner is provided, specifically a slightly positive pressure cabinet air conditioner, including a shell 11, a partition component is provided in the shell 11, and the partition component divides the internal space of the shell 11 into an indoor space and an outdoor space that are independent of each other, wherein an indoor heat exchanger 31 and an indoor fan 34 are provided in the indoor space, and an outdoor heat exchanger 41, an outdoor fan 42 and a compressor (not shown in the figure), a throttling element (not shown in the figure) and other related components are provided in the outdoor space. It can be understood that the indoor heat exchanger 31, the outdoor heat exchanger 41, the throttling element and the compressor are connected to form a refrigeration cycle, and the shell 11 also has an air induction channel 2, The air inlet of the induced air channel 2 is connected to the outdoor space, and the air outlet of the induced air channel 2 is connected to the indoor space. The air outlet of the induced air channel 2 is located on the air inlet side of the indoor heat exchanger 31, so that when the indoor fan 34 and the outdoor fan 42 are running at the same time, part of the air flow introduced into the outdoor space by the outdoor fan 42 through the outdoor air inlet 103 flows out through the outdoor air outlet 104 to cool the outdoor heat exchanger 41, and the other part enters the indoor space through the induced air channel 2 under the action of the indoor fan 34, and is sent to the temperature control space 100 through the indoor air outlet 101 after heat exchange and cooling at the indoor heat exchanger 31 together with the indoor return air entering through the indoor return air outlet 102. In this technical solution, the airflow from the outdoor space is directed into the indoor space via the induced air duct 2, thereby increasing the total amount of gas within the temperature-controlled space 100 and achieving the purpose of slightly positive pressure adjustment in the temperature-controlled space 100, effectively preventing outside air from entering the temperature-controlled space 100. Furthermore, the air outlet of the induced air duct 2 is located on the air inlet side of the indoor heat exchanger 31, allowing the outdoor airflow (hot air) to exchange heat with the indoor return airflow (cold air) through the indoor heat exchanger 31 before being delivered to the temperature-controlled space 100. This effectively prevents temperature fluctuations in the temperature-controlled space 100 caused by the airflow introduced during the slightly positive pressure adjustment process, thereby further stabilizing the temperature of the temperature-controlled space 100. It is understood that in order to achieve the purpose of slightly positive pressure adjustment in the temperature-controlled space 100, the temperature-controlled space 100 should theoretically be a sealed space. Of course, in practice, there may be air leakage in the temperature-controlled space 100, and the airflow introduced into the induced air duct 2 should be greater than the leakage in the temperature-controlled space 100.

[0022] The partition assembly includes a water tray 32, which is located at the bottom of the indoor heat exchanger 31. The air duct 2 includes an air duct that runs through the upper and lower sides of the water tray 32. That is, the water tray 32 is one of the components that separate the indoor and outdoor spaces. By providing an air duct that runs through the upper and lower sides of the water tray 32, the outdoor and indoor spaces can be connected very conveniently to achieve the purpose of air induction. More importantly, this structure greatly simplifies the structure of the air duct 2. It only requires adding a pipe of appropriate diameter (the specific diameter can be determined based on the positive pressure requirements and the speed and air volume of the indoor fan 34) to the corresponding water tray of the integrated air conditioner in the prior art. This greatly reduces product manufacturing costs and also achieves the purpose of slightly positive pressure air induction without requiring large-scale structural modifications.

[0023] The water receiving tray 32 has a water storage wall, that is, the water storage wall and the bottom wall of the water receiving tray 32 are together enclosed to form a storage space for condensed water. The height of the air duct in the water receiving space of the water receiving tray 32 is not lower than the height of the water storage wall, which can prevent condensed water from entering the outdoor space through the air duct and causing harm to the electrical components such as the compressor inside.

[0024] The partition assembly also includes a partition plate 33, one end of which is connected to the water tray 32. In another embodiment, the water tray 32 and the partition plate 33 are integrally formed to simplify the assembly process. As can be understood, the partition plate 33, as the main component of the partition assembly, should have a relatively smooth surface to smoothly guide the airflow within the corresponding indoor and outdoor spaces.

[0025] A flow regulating structure is provided at the outlet of the induced draft duct, the purpose of which is to adjust the flow of the air flow introduced by the induced draft duct so as to maintain the pressure difference between the temperature-controlled space 100 and the outdoor environment within a preset value range that meets the requirements. The flow regulating structure can be a component that is manually opened and adjusted. As a better implementation method, the flow regulating structure can specifically include a flow regulating valve. The opening of the flow regulating valve can be adjusted according to the pressure difference between the indoor space and the outdoor space (electrically controlled and automatically adjusted). The aforementioned pressure difference can be specifically obtained by arranging an air pressure sensor at the air inlet and the air outlet of the induced draft channel 2 to obtain the pressure respectively and then make the difference. As a relatively well-known technical means, the present invention will not elaborate on it.

[0026] In order to improve the cleanliness of the airflow introduced into the outdoor space, a corresponding filter component, such as a filter, can be installed at the air inlet of the outdoor space. Preferably, the filter component is installed at the air inlet of the air duct 2. This allows for targeted filtration and cleaning of the airflow entering the indoor space, thereby increasing the service life of the filter component. Of course, in some cases, filter components can be installed at both the air inlet of the outdoor space and the air inlet of the air duct 2. However, two filter components with different filtration grades can be selected, and the grade of the filter component at the air duct 2 can be selected to be higher. This ensures the cleanliness of both the outdoor space and the introduced airflow while reducing costs.

[0027] Only one indoor fan 34 is set in the indoor space, that is, the indoor return air of the air conditioner and the introduction of outdoor airflow are achieved through the operation of one indoor fan 34, without setting a corresponding fan separately for the introduction of outdoor airflow (such as the fresh air fan in the prior art). This can further reduce the manufacturing cost of the air conditioner and make the structure of the air conditioner more compact and occupy less space.

[0028] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0029] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art may make various improvements and variations without departing from the technical principles of the present invention, and such improvements and variations shall also be considered within the scope of protection of the present invention.
