Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-2, the present embodiment provides a cabinet air conditioner with a fresh air channel, which includes a cabinet housing 9, an inner circulation chamber 10 and an outer circulation chamber 11, and a middle partition plate 8 is disposed between the inner circulation chamber 10 and the outer circulation chamber. And a breeze valve device 6 is arranged on one side of the middle partition plate 8 facing the inner circulation chamber, and the breeze valve device 6 is communicated with the inner circulation chamber 10 and the outer circulation chamber 11 and controls the opening and closing of a fresh air channel between the inner circulation chamber 10 and the outer circulation chamber 11. In order to prevent dust particles carried by fresh air from entering the cabinet internal environment, such as the internal circulation chamber 10, the breeze valve device 6 is connected with a filter device 12, the filter device 12 is positioned in the internal circulation chamber 10, and the fresh air entering the internal circulation chamber 10 through the fresh air channel can be filtered.

The internal circulation chamber 10 is provided with an internal circulation fan 2 and an evaporator 4, and the controller 7 can also be arranged in the internal circulation chamber; the external circulation chamber 11 is installed with a compressor 1, an external circulation fan 3, and a condenser 5. Optionally, the inner circulation chamber 10 is provided with a first pressure sensor (not shown in the figure), and the outer circulation chamber 11 is provided with a second pressure sensor (not shown in the figure), so as to monitor the air pressure of the inner circulation chamber 10 and the air pressure of the outer circulation chamber 11 in real time; or, the inner circulation chamber and the outer circulation chamber are respectively provided with a temperature sensor (not shown in the figure), the controller 7 is connected with the two temperature sensors, and the breeze valve device 6 is controlled to work according to signals of the two temperature sensors; or the inner circulation chamber or the outer circulation chamber is provided with a differential pressure switch (not shown in the drawings) so as to monitor the differential pressure between the inner circulation chamber 10 and the outer circulation chamber 11 in real time. For example, when the temperature in the cabinet is too high (high temperature alarm point), the controller controls to turn on the hydrogen exhaust fan, the breeze valve device 6 works, and the air valve 61 is opened, so that the forced ventilation function can be realized, the temperature in the cabinet is reduced, and the temperature in the cabinet is ensured to be in a reasonable range.

as shown in fig. 2, the microvalve device has an air valve 61, and a valve adjusting mechanism configured to adjust an opening angle or an opening area of the air valve 61 is connected to the microvalve device 61, thereby controlling the amount of air introduced into the internal circulation chamber 10. Wherein the valve adjustment mechanism comprises a drive motor 64. According to one embodiment of the application, the air valve 61 is rotatably mounted on the middle partition plate 8, and the valve adjusting mechanism adopts a slider rocker structure, so that the opening angle of the air valve 61 can be accurately controlled, for example, the air valve is rotated to be opened by 30 degrees; according to another embodiment of the application, the air valve 61 is liftably mounted on the middle partition plate 8, and the valve adjusting mechanism adopts a rack-and-pinion structure, so that the opening area of the air valve 61, for example, the opening 1/3, can be precisely controlled. Optionally, the valve adjusting mechanism further comprises a first limit switch 62 and a second limit switch 63, and when the air valve 61 is in the first working position, the first limit switch 62 is triggered; when the air valve is in the second working position, the second limit switch 63 is triggered. The first working position and the second working position of the air valve 61 are reasonably selected according to actual working requirements. For example, when the air valve 61 is opened by 90 degrees, the air valve 61 is in the first working position; when the air valve 61 is closed, the air valve 61 is in the second working position.

The working process of the cabinet air conditioner in the embodiment is described in detail as follows:

A fresh air channel controlled by a breeze valve device 6 is added on a middle partition plate 8 of the cabinet air conditioner, the breeze valve device 6 is installed on the middle partition plate 8 through screws, the opening and closing of a breeze valve 61 are controlled through a controller 7, and the controller 7 obtains an action signal through the pressure difference of an inner circulation chamber 10 and an outer circulation chamber 11 (for example, according to the detection results of a first pressure sensor and a second pressure sensor or according to the detection result of a pressure difference switch). When the pressure of the inner circulation chamber 10 is smaller than the pressure difference of the outer circulation chamber and reaches a preset value, the control panel 7 controls the breeze valve device 6 to work according to collected or received signals, opens the air valve 61, introduces fresh air and increases the pressure of the inner circulation chamber 10, and conversely, closes the air valve 61 to ensure positive pressure in the cabinet relative to the environment outside the cabinet (namely the inner circulation chamber 10 relative to the outer circulation chamber 11).

Meanwhile, according to the environment requirement in the cabinet, when the temperature in the cabinet is too high (high temperature alarm point), the controller controls the hydrogen exhaust fan to be started, the breeze valve device 6 works, the fresh air channel is opened, the forced ventilation function can be realized, the temperature in the cabinet is reduced, and the temperature in the cabinet is ensured within a reasonable range. When the air-conditioning refrigeration system of the cabinet fails, the internal circulation fan 2 can still normally operate, air is supplied through the fresh air channel, the exhaust fan exhausts air to dissipate heat, namely, the fresh air circulation in the cabinet can still undertake the heat dissipation of equipment, and a heat dissipation backup redundancy design in the cabinet is formed. Further, when the temperature of the cabinet is lower than the preset value, the cabinet air conditioner refrigeration system stops running, heat can be dissipated through direct ventilation of the fresh air channel, the applicable environment temperature range in the cabinet is improved, and therefore the purpose of energy saving in running of the cabinet air conditioner is achieved.
