However, traditional outdoor cabinet air conditioners are limited by their own structure, and the cooling components need to be in continuous operation whenever cooling is required, resulting in long operating time of the cooling components throughout the year and high energy consumption.

[0003] Therefore, there is an urgent need to research an energy-saving air conditioner to avoid the refrigeration components being constantly in operation and consuming high amounts of energy. Utility Model Content

[0011] The valve body is located inside the fresh air duct and is used to control the opening and closing of the fresh air duct.

[0012] As an optional technical solution for energy-saving air conditioning, the commutator is plate-shaped and is used to block the air inlet of the indoor exhaust duct or the air inlet of the outdoor exhaust duct during rotation, so that the indoor air inlet is connected to the corresponding outdoor exhaust duct or indoor exhaust duct.

[0013] As an optional technical solution for energy-saving air conditioning, the reversing assembly includes a reversing shaft, which is disposed inside the housing and located on the extension line of the indoor air inlet. The reversing member is used to rotate around the reversing shaft to guide the airflow entering from the indoor air inlet to the outdoor exhaust duct, or to guide it to the indoor exhaust duct.

[0014] As an optional technical solution for energy-saving air conditioning, the commutation assembly includes a commutation drive component, the commutation shaft is rotatably disposed within the housing and fixedly connected to the commutation component, and the drive end of the commutation drive component is drively connected to the commutation shaft.

[0021] The beneficial effects of this utility model are as follows:

[0022] This utility model provides an energy-saving air conditioner, which includes an air supply component, a cooling component, and a reversing component. The reversing component connects the indoor air inlet to the indoor exhaust duct or the outdoor exhaust duct. Both the indoor exhaust duct and the fresh air duct are connected to the air supply duct. A valve controls the fresh air duct, allowing outside air to enter the air supply duct through the fresh air duct when the valve is open. Therefore, when cooling is needed, two modes can be selected: In the first cooling mode, indoor airflow flows through the indoor air inlet, then through the indoor exhaust duct and the air supply duct, and finally enters the room through the indoor air outlet. The airflow is cooled by the cooling component as it passes through the air supply duct. In the second cooling mode, when the outdoor temperature is lower than the preset energy-saving temperature, indoor airflow flows through the indoor air inlet, then through the outdoor exhaust duct and is discharged outdoors. Cold outdoor air can flow through the fresh air duct, then through the air supply duct, and finally enter the room through the indoor air outlet. In the second cooling mode, the cooling component does not need to operate, thus saving energy and reducing annual energy consumption. Attached Figure Description

[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] like Figures 1 to 4As shown, this embodiment provides an energy-saving air conditioner, which includes a housing 100, an air supply component 200, a refrigeration component 300, a reversing component 400, and a valve body 500. The housing 100 has an internal air supply duct 110, an indoor exhaust duct 120, an outdoor exhaust duct 130, and a fresh air duct 140. The housing 100 has an indoor air outlet 150 communicating with the air supply duct 110 and an indoor air inlet 160. The air supply component 200 is disposed within the air supply duct 110 and is used to supply air to the indoor air outlet 150. The refrigeration component of the refrigeration component 300 is located within the air supply duct 110. The reversing component 400 includes a reversing element 410. The component 410 is rotatably mounted on the housing 100 and can connect the indoor air inlet 160 to one end of the indoor exhaust duct 120 or one end of the outdoor exhaust duct 130; the other end of the indoor exhaust duct 120 is connected to the supply air duct 110, and the other end of the outdoor exhaust duct 130 is connected to the outside; one end of the fresh air duct 140 is connected to the outside, and the other end is connected to the supply air duct 110; the valve body 500 is mounted on the fresh air duct 140 and is used to control the opening and closing of the fresh air duct 140.

[0040] With the above-mentioned structural design, cooling is activated when the indoor temperature exceeds the preset energy-saving temperature. Two cooling modes are available: the first mode is described in detail below. Figure 3 When the outdoor temperature is higher than the preset energy-saving temperature, the airflow on the indoor side flows through the indoor air inlet 160, then through the indoor exhaust duct 120 and the supply air duct 110, and finally re-enters the indoor side through the indoor air inlet 160. The airflow is cooled by the cooling components as it passes through the supply air duct 110. The second cooling mode is described in detail below. Figure 4 When the outdoor temperature is lower than the preset energy-saving temperature, the airflow on the indoor side flows through the indoor air inlet 160, passes through the outdoor exhaust duct 130, and is discharged to the outdoor side. At the same time, the cold air on the outdoor side can flow through the fresh air duct 140, pass through the air supply duct 110, and finally enter the indoor side through the indoor air inlet 160. In the second cooling mode, the cooling components can stop working, thereby saving energy and reducing the annual energy consumption.

[0041] It should be noted that the concept of cooling temperature hysteresis needs to be introduced during use. The energy-saving temperature preset value is the sum of the cooling temperature setpoint and the cooling temperature hysteresis. That is, there is a difference between the cooling temperature setpoint and the actual indoor temperature that can be cooled. This difference is called the cooling temperature hysteresis. For example, when the indoor temperature needs to be maintained at 23℃, that is, the energy-saving temperature preset value is 23℃, and the cooling temperature hysteresis is 6℃, the cooling temperature setpoint should be 17℃. In this embodiment, cooling is activated when the indoor temperature is higher than 23℃.

[0042] Furthermore, to ensure the accuracy of the cooling start-up timing, cooling can be activated only after the indoor temperature has been above the preset energy-saving temperature for a preset time period. Similarly, the second cooling mode can be activated only after the outdoor temperature has been below the preset energy-saving temperature for a preset time period.

[0043] In some embodiments, the refrigeration assembly 300 includes a condenser 310 and a compressor 320, and the refrigeration component includes an evaporator 330. The evaporator 330 is located in the air supply duct 110, and both the condenser 310 and the compressor 320 are located in the outdoor exhaust duct 130. The refrigeration method using the compressor 320 is simple in structure and easy to implement. It should be noted that the principle and method of achieving refrigeration through the cooperation of the compressor 320, condenser 310, and evaporator 330 are well known to those skilled in the art, and therefore will not be described in detail here.

[0044] In some embodiments, the reversing member 410 is plate-shaped. During rotation, the reversing member 410 can block the air inlet of the indoor exhaust duct 120 or the air inlet of the outdoor exhaust duct 130, so that the indoor air inlet 160 can connect to the corresponding outdoor exhaust duct 130 or indoor exhaust duct 120. This structure is easy to process and install, and improves production efficiency.

[0045] The commutation assembly 400 includes a commutation shaft 420, which is disposed on the housing 100 and located on the extension line of the indoor air inlet 160. A commutation element 410 is rotatable around the axis of the commutation shaft 420. When the commutation element 410 blocks the air inlet of the indoor exhaust duct 120, a first guide surface is formed on the side of the commutation element 410 facing the indoor air inlet 160 to guide the airflow entering from the indoor air inlet 160 to the outdoor exhaust duct 130. When the commutation element 410 blocks the air inlet of the outdoor exhaust duct 130, a second guide surface is formed on the side of the commutation element 410 facing the indoor air inlet 160 to guide the airflow entering from the indoor air inlet 160 to the indoor exhaust duct 120. The plate-like structure of the commutation element 410 serves both a blocking and guiding function, improving the smoothness of airflow. Simultaneously, in the second cooling mode, the commutation element 410 isolates the indoor and outdoor airflows, preventing them from mixing and improving cooling efficiency. In this embodiment, when the reversing member 410 rotates from blocking the air inlet of the indoor exhaust duct 120 to blocking the air inlet of the outdoor exhaust duct 130, it can rotate 50° to 90°. For example, in this embodiment, it rotates 60°.

[0046] To improve the automation level of energy-saving air conditioners, the commutation assembly 400 includes a commutation drive 430. The commutation shaft 420 is rotatably mounted on the housing 100 and fixedly connected to the commutation assembly 410. The commutation drive 430 is located in the housing 100, and its drive end is connected to the commutation shaft 420 for transmission. The commutation drive 430 can be a servo motor or an electric valve.

[0047] The energy-saving air conditioner includes a return air temperature sensor 610, which is located inside the indoor exhaust duct 120. The return air temperature sensor 610 is communicatively connected to the controller. The refrigeration component 300 and the air supply component 200 are also communicatively connected to the controller. The return air temperature sensor 610 sends a first temperature signal to the controller when it detects that the return air temperature is higher than the preset energy-saving temperature value. The controller receives the first temperature signal and sends a cooling signal to the refrigeration component 300 to start cooling or open the valve 500, and controls the air supply component 200 to deliver air. This configuration allows the cooling function to start automatically, improving the automation level of temperature control. The return air temperature is the temperature of the air flowing out from the indoor side, i.e., the indoor air temperature.

[0048] Furthermore, the energy-saving air conditioner includes an outdoor temperature sensor 620, which is located in the outdoor exhaust duct 130 and is situated outdoors. The outdoor temperature sensor 620 is communicatively connected to the controller, and the commutation drive 430 and valve body 500 are also communicatively connected to the controller. The outdoor temperature sensor 620 sends a second temperature signal to the controller when the outdoor temperature is lower than the preset energy-saving temperature value. The controller receives the second temperature signal and controls the commutation drive 430 and valve body 500 to open, connecting the indoor air inlet 160 to the corresponding outdoor exhaust duct 130 and opening the valve body 500. At this time, the second cooling mode is activated. See [link to relevant documentation]. Figure 4 .

[0049] When the outdoor temperature is higher than the preset energy-saving temperature, a third temperature signal is sent to the controller. Upon receiving the third temperature signal, the controller activates the reversing drive 430 and the valve body 500 to connect the indoor air inlet 160 to the corresponding indoor exhaust duct 120. The compressor 320 operates, and the valve body 500 closes. At this time, the first cooling mode is activated. (See [link to relevant documentation]). Figure 3 In this embodiment, the outdoor temperature sensor 620 is located upstream of the condenser 310 along the gas flow path.

[0050] In this embodiment, when the outdoor temperature is higher than the preset energy-saving temperature and the compressor 320 fails to start due to a malfunction, the compressor 320 is shut down when the outdoor temperature is lower than the indoor temperature. A second cooling mode is then activated, where the indoor air inlet 160 connects to the corresponding outdoor exhaust duct 130, and the valve 500 is opened. This method provides emergency cooling and reduces the probability of excessively high indoor temperatures due to compressor 320 failure.

[0051] The housing 100 has an outdoor air outlet 180 and an outdoor air inlet 190, both of which are connected to the outdoor exhaust duct 130. The cooling assembly 300 also includes an outdoor fan 340, which is located at the outdoor air outlet 180 and is used to blow airflow from the outdoor exhaust duct 130 to the outdoor air outlet 180, i.e., to exhaust air to the outside. In this embodiment, in the first cooling mode, the outdoor fan 340 circulates the outdoor airflow, which is beneficial for the heat dissipation of the condenser 310.

[0052] To improve the heat dissipation efficiency of the condenser 310, further, along the gas flow path, the outdoor air inlet 190 is located upstream of the condenser 310, and the outdoor air outlet 180 is located downstream of the condenser 310. In the second cooling mode, the condenser 310 stops working, while the outdoor fan 340 remains operational, directing indoor airflow through the indoor air inlet 160, through the outdoor exhaust duct 130, and then through the outdoor fan 340 to the outside, thus achieving ventilation. In this embodiment, the outdoor air inlet 190 can be opened or closed.

[0053] To ensure the quality of air entering the room, in some embodiments, the energy-saving air conditioner includes a filter 700, which is disposed in the air supply duct 110, the indoor exhaust duct 120, or the fresh air duct 140. Exemplarily, the filter 700 is disposed in the air supply duct 110 near the inlet of the indoor exhaust duct 120, that is, the filter 700 is disposed in the air supply duct 110 near the inlet of the fresh air duct 140. Airflow from both the indoor exhaust duct 120 and the fresh air duct 140 must pass through the filter 700 before entering the air supply duct 110, reducing the number of filters 700 and lowering costs. In other embodiments, the filter 700 may be disposed at the inlet of the fresh air duct 140, the inlet of the indoor exhaust duct 120, or the indoor air outlet 150.

[0054] The energy-saving air conditioner in the above embodiments can select a suitable cooling mode according to the different outdoor temperatures after the cooling starts. The first cooling mode is described below. Figure 3 and Figure 1 When compressor 320 is turned on, reversing component 410 rotates to the position blocking the air inlet of outdoor exhaust duct 130, so that indoor air inlet 160 connects to indoor exhaust duct 120. Valve 500 closes, and indoor air enters from indoor air inlet 160, passes through indoor exhaust duct 120, and enters supply air duct 110. It is cooled as it flows through compressor 320, and then enters the room for further cooling. Outdoor fan 340 and supply air component 200 remain on, and outdoor airflow enters outdoor exhaust duct 130 through outdoor air inlet 190 and is carried away by outdoor fan 340. For the second cooling mode, see [link to cooling mode description]. Figure 4 and Figure 1When compressor 320 is turned off, reversing component 410 rotates to block the air inlet of indoor exhaust duct 120, so that indoor air inlet 160 is connected to outdoor exhaust duct 130. Valve body 500 is opened, and outdoor low-temperature air is brought into fresh air duct 140 by valve body 500, and enters the room for cooling after passing through air supply duct 110. Outdoor fan 340 and air supply component 200 continue to be turned on, and indoor hot air flows through indoor air inlet 160 and is carried away by outdoor fan 340.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
