Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly to an air conditioner, a control method for an air conditioner, and a computer-readable storage medium. Background Art

[0002] An air conditioner is a special device that uses a refrigeration system to adjust the temperature, humidity, cleanliness, and air velocity of a predetermined place, so that the air quality meets the requirements of life, production, and scientific research. The refrigeration system usually includes components such as a compressor, a condenser, an expansion device, and an evaporator connected in sequence through pipelines to form a refrigeration circuit that allows a refrigerant medium to circulate therein. Air conditioners are widely used in various places, such as office buildings, shopping malls, hotels, residences, factories, etc.

[0003] An air conditioner usually includes an outdoor unit arranged outdoors and an indoor unit arranged in the regulated space. Among them, the outdoor unit usually includes a housing, an outdoor heat exchanger arranged in the housing, an outdoor fan, a compressor, and electrical control components, etc. When the external environmental temperature is relatively high (such as in summer), the air conditioner usually operates in the cooling mode. At this time, the outdoor heat exchanger acts as a condenser, and the compressor also generates a large amount of heat during operation, resulting in a relatively high temperature inside the entire outdoor unit housing, which greatly affects the safety, stability, and reliability of the electrical control components.

[0004] Therefore, a new technical solution is needed in the art to solve the above problems. Summary of the Invention

[0005] In order to solve or to a certain extent improve the technical problem in the prior art that the performance of the electrical control components in the outdoor unit is reduced due to excessive temperature, the present invention provides an air conditioner. The air conditioner has an outdoor unit, and the outdoor unit includes a housing, a compressor, electrical control components, an outdoor fan, and an outdoor heat exchanger. A first chamber for accommodating the compressor and the electrical control components and a second chamber for accommodating the outdoor fan and the outdoor heat exchanger are formed on the housing. The first chamber and the second chamber are interconnected through ventilation holes, and an air inlet that allows external air to enter the first chamber and can be opened and closed is provided on the housing.

[0006] As will be understood by those skilled in the art, the air conditioner of the present invention includes an outdoor unit. The outdoor unit includes a housing, a compressor, an electronic control component, an outdoor fan, and an outdoor heat exchanger. A first chamber and a second chamber, spaced apart from each other, are formed on the housing. The compressor and the electronic control component are arranged in the first chamber, while the outdoor fan and the outdoor heat exchanger are arranged in the second chamber. The first chamber and the second chamber are interconnected via ventilation holes. The housing is also provided with an openable and closable air inlet that allows external air to enter the first chamber. Therefore, when the external ambient temperature gradually rises, the operation of the compressor and the electronic control component generates more heat in the first chamber. By opening the air inlet in a timely manner, the effective area for external air to enter the housing can be increased, preventing heat from accumulating in the first chamber, thereby effectively reducing the operational stability of the electronic control component and preventing the electronic control component from operating in a high-temperature environment, which may cause performance degradation, component damage, or even safety accidents, thereby ensuring the normal operation and service life of the outdoor unit.

[0007] In the preferred technical solution of the air conditioner, the electronic control components are positioned above the compressor, and the ventilation holes are located near the electronic control components. Placing the compressor at the bottom ensures its stability and prevents significant vibration during compressor operation. Placing the electronic control components above the compressor prevents moisture damage to the components, improving their safety. Furthermore, the ventilation holes are located near the electronic control components, allowing air to flow away from the surface of the components, thereby improving cooling and heat dissipation.

[0008] In a preferred technical solution of the above air conditioner, a temperature detector is further provided in the first chamber to accurately detect the temperature of the first chamber.

[0009] In the preferred technical solution of the air conditioner, a fixed auxiliary air inlet is further provided on the housing. The provision of the auxiliary air inlet can ensure that external air can enter the first chamber more conveniently and evenly.

[0010] In a preferred technical solution of the above air conditioner, the temperature detector is positioned close to the electronic control component to accurately obtain the temperature near the electronic control component.

[0011] In the preferred technical solution of the air conditioner described above, the air inlet is provided with a damper; alternatively, the air inlet is provided with a louver with an adjustable opening. The damper allows for precise and flexible control of the opening and degree of the air inlet. Similarly, the louver allows for convenient adjustment of the opening and degree of the air inlet, while also improving the uniformity of the incoming air.

[0012] In order to solve or to a certain extent improve the technical problem in the prior art that the performance of the electronic control components in the outdoor unit is reduced due to excessive temperature, the present invention provides a control method for an air conditioner. The air conditioner has an outdoor unit, and the outdoor unit includes a housing, a compressor, an electronic control component, an outdoor fan, and an outdoor heat exchanger. A first chamber for accommodating the compressor and the electronic control component and a second chamber for accommodating the outdoor fan and the outdoor heat exchanger are formed on the housing. The first chamber and the second chamber are communicated with each other through a ventilation hole. An air inlet allowing external air to enter the first chamber and capable of being opened and closed is provided on the housing. And the control method includes: obtaining the actual temperature of the first chamber; comparing the actual temperature with a first preset temperature; and controlling the rotation speed of the outdoor fan and the opening and closing of the air inlet based on the comparison result.

[0013] Those skilled in the art can understand that the control method for the air conditioner of the present invention first obtains the actual temperature of the first chamber for accommodating the compressor and the electronic control component, then compares the measured actual temperature with the first preset temperature, and then controls the rotation speed of the outdoor fan and the opening and closing of the air inlet provided on the housing of the outdoor unit based on the comparison result. When the actual temperature in the first chamber is relatively high, by adjusting the rotation speed of the outdoor fan and the opening and closing of the air inlet on the housing, more external air can flow into the first chamber faster. When the air passes through the surface of the electronic control component, it can take away the heat, reducing the temperature of the electronic control component. In addition, after the air flows through the surface of the electronic control component, it will enter the second chamber through the ventilation hole between the first chamber and the second chamber, and will not stay in the first chamber, ensuring the heat dissipation efficiency. Therefore, the control method of the present invention can significantly reduce the actual temperature of the first chamber, avoid the reduction of performance, component damage or even safety accidents caused by the electronic control component working in a high-temperature environment, and ensure the normal operation and service life of the outdoor unit.

[0014] In a preferred technical solution of the above control method for an air conditioner, the outdoor fan includes an upper fan and a lower fan spaced apart from each other in the vertical direction. And when the actual temperature exceeds the first preset temperature, the control method includes: obtaining the actual rotation speed of the upper fan; comparing the actual rotation speed with a preset maximum rotation speed; when the actual rotation speed is less than the preset maximum rotation speed, controlling the upper fan to increase the rotation speed; and when the actual rotation speed is equal to the preset maximum rotation speed, keeping the upper fan running at the preset maximum rotation speed. Through the above settings, the rotation speed of the upper fan can be accurately adjusted according to the actual temperature in the first chamber, ensuring the heat dissipation accuracy of the electronic control component.

[0015] In the preferred technical solution of the above control method for an air conditioner, after the upper fan operates at the preset maximum speed, the control method further includes: after a preset time period, acquiring the actual temperature again; comparing the newly acquired actual temperature with the first preset temperature; when the newly acquired actual temperature exceeds the first preset temperature, controlling the air inlet to open. When the upper fan operates at the preset maximum speed, if the actual temperature in the first chamber still exceeds the first preset temperature, then control the air inlet on the housing to open, so that more external air enters the first chamber to participate in cooling and heat dissipation, thereby more efficiently reducing the temperature in the first chamber.

[0016] In the preferred technical solution of the above control method for an air conditioner, after the air inlet is opened, the control method further includes: after the preset time period, acquiring the actual temperature again; comparing the newly acquired actual temperature with the second preset temperature; when the newly acquired actual temperature is greater than the second preset temperature, controlling the air inlet to increase its opening degree or keeping the air inlet open; when the newly acquired actual temperature is less than or equal to the second preset temperature, controlling the air inlet to close, where the second preset temperature is less than the first preset temperature. Controlling the air inlet to close only when the actual temperature in the first chamber drops to the second preset temperature can ensure that the electronic control components have a good working environment and avoid frequent control.

[0017] In the preferred technical solution of the above control method for an air conditioner, the speed of the upper fan is greater than or equal to the speed of the lower fan. Setting the speed of the upper fan to be greater than or equal to the speed of the lower fan can better cool the electronic control components located in the upper part by using the upper fan with a higher speed, and improve the utilization efficiency of the fan.

[0018] To solve or to some extent improve the technical problem in the prior art that the performance of the electronic control components in the outdoor unit is reduced due to excessive temperature, the present invention provides a computer-readable storage medium. A computer program is stored in the computer-readable storage medium, and the computer program can be executed by a processor to implement the control method for an air conditioner according to any one of the above.

[0027] The preferred implementation manners of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention. It should be noted that in the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0028] In order to solve or to a certain extent improve the technical problem in the prior art that the performance of the electric control component in the outdoor unit is reduced due to excessive temperature, the present invention provides a control method for an air conditioner 100. The air conditioner 100 has an outdoor unit 110, and the outdoor unit 110 includes a housing 111, a compressor 112, an electric control component 116, an outdoor fan 114 and an outdoor heat exchanger 113. A first chamber 1111 for accommodating the compressor 112 and the electric control component 116 and a second chamber 1112 for accommodating the outdoor fan 114 and the outdoor heat exchanger 113 are formed on the housing 111. The first chamber 1111 and the second chamber 1112 are interconnected through a ventilation hole 1117, and an air inlet 1114 that allows external air to enter the first chamber 1111 and can be opened and closed is provided on the housing 111.

[0029] Figure 1 It is a system configuration diagram of an embodiment of the air conditioner according to the present invention. As Figure 1As shown, in one or more embodiments, the air conditioner 100 of the present invention includes an outdoor unit 110 (which is generally arranged in an outdoor environment) and four parallel indoor units 120 (which are generally arranged indoors or in a room). Alternatively, the number of indoor units 120 can also be set to other suitable numbers more or less than four, such as one, two, three, five, etc. According to actual needs, the configurations of multiple indoor units 120 can be the same or different.

[0030] Figure 2 is a schematic structural view of an embodiment of the housing of the outdoor unit of the air conditioner of the present invention. As Figure 1 and Figure 2 shown, in one or more embodiments, the outdoor unit 110 includes a housing 111, a compressor 112, an outdoor heat exchanger 113, an outdoor fan 114, a throttling component 115, an electronic control component 116, etc.

[0031] Continue to refer to Figure 2 , the housing 111 has a generally cuboid shape. Inside the housing 111, there is a partition plate 1113 extending generally in the vertical direction, so as to divide the housing 111 into a first chamber 1111 and a second chamber 1112. Based on Figure 2In the illustrated orientation, the first chamber 1111 is located on the left, while the second chamber 1112 is located on the right. The first chamber 1111 houses the compressor 112 and the electronic control component 116, while the second chamber 1112 houses the outdoor heat exchanger 113 and the outdoor fan 114. A throttle component 115 may also be disposed within the first chamber 1111. In one or more embodiments, the compressor 112 is disposed in the lower portion of the first chamber 1111, while the electronic control component 116 is disposed in the upper portion of the first chamber 1111. In other words, the electronic control component 116 is disposed above the compressor 112. Placing the compressor 112 in the lower portion of the first chamber 1111 ensures its stability and prevents significant vibration during operation. Placing the electronic control component 116 in the upper portion of the first chamber 1111 prevents moisture from damaging the electronic control component 116, improving its safety. A plurality of ventilation holes 1117 spaced apart from each other are provided on the partition plate 1113, so that the first chamber 1111 and the second chamber 1112 can be connected to each other by air through the ventilation holes 1117. In one or more embodiments, the ventilation holes 1117 are positioned near the electronic control component 116 so that the air can better remove the temperature of the surface of the electronic control component 116 during the flow, thereby improving the cooling and heat dissipation effect. In one or more embodiments, a temperature detector 1118 is further provided in the first chamber 1111 to accurately detect the temperature in the first chamber 1111. Preferably, the temperature detector 1118 is arranged near the electronic control component 116 to more accurately know the operating temperature of the electronic control component 116. The temperature detector 1118 can be, but is not limited to, a resistive temperature sensor.

[0032] Continue to see Figure 2 In one or more embodiments, an openable and closable air inlet 1114 is provided on the housing 111. Figure 2 In the orientation shown, the air inlet 1114 is arranged on the left side wall of the housing 111. Alternatively, the air inlet 1114 may also be set at other suitable locations, such as on the front side wall or the rear side wall. In one or more embodiments, the height of the air inlet 1114 in the vertical direction is lower than the height of the electronic control component 116. In this way, when the air inlet 1114 is in the open state, it is difficult for moisture from the external environment (such as rainwater) to enter the electronic control component 116 through the air inlet 1114, thereby ensuring the safety of the electronic control component 116. In one or more embodiments, an air valve 1115 is provided at the air inlet 1114 to control the opening and closing and opening degree of the air inlet 1114. The type of the air valve 1115 is not limited, such as a butterfly valve, a ball valve, etc. Alternatively, the air inlet 1114 may also be configured as a shutter with adjustable opening or other suitable form. When the air inlet 1114 is opened, air from the external environment can easily enter the first chamber 1111 through the air inlet 1114 to cool down and dissipate heat for the electronic control component 116 .

[0033] Continue to refer to Figure 2 , in one or more embodiments, a fixed auxiliary air inlet 1116 is provided on the housing 111 to ensure that external air can enter the first chamber 1111 more conveniently and evenly. The auxiliary air inlet 1116 can be arranged on the left side wall, the rear side wall and the front side wall of the housing 111. The specific form of the auxiliary air inlet 1116 is not limited, for example, it can be a louver type.

[0034] In one or more embodiments, the compressor 112 is a variable frequency compressor 112. The number of compressors 112 can be one or more. The outdoor heat exchanger 113 can be, but is not limited to, a finned coil heat exchanger. The outdoor fan 114 faces the outdoor heat exchanger 113 to improve the heat exchange efficiency between the external air and the outdoor heat exchanger 113. In one or more embodiments, the outdoor fan 114 includes an upper fan 1141 and a lower fan 1142 spaced apart from each other in the vertical direction to further improve the heat exchange efficiency of the outdoor heat exchanger 113. In one or more embodiments, the rotational speed of the upper fan 1141 is greater than or equal to the rotational speed of the lower fan 1142, so as to better cool the electronic control components 116 located in the upper part by using the upper fan 1141 with a higher rotational speed and improve the utilization efficiency of the fan. The throttling component 115 can be, but is not limited to, an electronic expansion valve.

[0035] In one or more embodiments, the electronic control components 116 include components such as a main control board, a power supply board, a compressor drive board, a fan drive board, auxiliary components, and a communication interface (not shown in the figure). The main control board integrates components such as a central processing unit (i.e., CPU) and a computer-readable storage medium to realize intelligent control of the entire air conditioner 100 by executing a preset program. The power supply board is responsible for converting the input alternating current into a suitable direct current power supply for each electrical component, and it includes, but is not limited to, circuits such as rectification, filtering, and voltage stabilization. The compressor drive board and the fan drive board are respectively used to drive and control the working states of the compressor 112 and the fan. The auxiliary components include, but are not limited to, terminal blocks, relays, varistors, rectifier diodes, etc. These components play roles such as tuning, filtering, coupling, protection, rectification, isolation, and voltage stabilization in the circuit to ensure the stable operation of the electronic control system. The communication interface is used to realize the communication connection between the outdoor unit 110 and the indoor unit 120 to ensure the accurate transmission of information exchange and control instructions.

[0036] Continue to refer to Figure 1 , in one or more embodiments, each indoor unit 120 includes components such as an indoor heat exchanger 121 and an indoor fan 122. The indoor heat exchanger 121 can be, but is not limited to, a finned coil heat exchanger. The indoor fan 122 faces the indoor heat exchanger 121 to improve the heat exchange efficiency between the indoor air and the indoor heat exchanger 121.

[0037] Continue to refer toFigure 1 , the exhaust port of the compressor 112 (not labeled in the figure) is connected to the outdoor heat exchanger 113. The outdoor heat exchanger 113 is connected to a plurality of throttling components 115. Each throttling component 115 is connected to a corresponding indoor heat exchanger 121. The plurality of indoor heat exchangers 121 are connected to the suction port of the compressor 112 (not labeled in the figure) through a header pipe. Through the above arrangement, a refrigeration circuit allowing the refrigerant medium to circulate therein is formed. In one or more embodiments, a gas-liquid separator (not shown in the figure) is provided near the suction port of the compressor 112 to ensure the smooth operation of the compressor 112. In one or more embodiments, the air conditioner 100 further includes a four-way valve (not labeled in the figure). The four-way valve has a D port connected to the exhaust port of the compressor 112, a C port connected to the outdoor heat exchanger, an E port connected to the indoor heat exchanger 121, and an S port connected to the suction port of the compressor 112. With the help of the four-way valve, the air conditioner 100 can be conveniently switched between the heating mode and the cooling mode.

[0038] Next, in combination with the attached Figures 3 - 5 The control method of the present invention for the air conditioner 100 will be introduced in detail. It should be noted that the control method of the present invention for the air conditioner 100 can be executed in the air conditioner 100 of any of the above embodiments, or can be applied to other suitable air conditioners 100.

[0039] Figure 3 is a schematic flow chart of the control method of the present invention for an air conditioner. As Figure 3 shown, in one or more embodiments, when the control method of the present invention for the air conditioner 100 starts, step S1 is first executed, that is, the actual temperature of the first chamber 1111 is obtained. The actual temperature of the first chamber 1111 can be measured by a temperature detector 1118 arranged in the first chamber 1111. Then, the control method executes step S2 to compare the actual temperature with the first preset temperature. Then, based on the comparison result, the rotation speed of the outdoor fan 114 and the opening and closing of the air inlet 1114 are controlled (that is, step S3).

[0040] Figure 4 is a schematic flow chart of the first embodiment of the control method of the present invention for an air conditioner. As Figure 4As shown, in one or more embodiments, the outdoor fan 114 includes an upper fan 1141 and a lower fan 1142 that are spaced apart from each other in the vertical direction. After the control method for the air conditioner 100 of the present invention starts, step S10 is first executed, that is, the actual temperature of the first chamber 1111 is obtained. Then, the actual rotational speed is compared with the preset maximum rotational speed. That is, it is judged whether the measured actual temperature is greater than the first preset temperature (i.e., step S20). In one or more embodiments, the first preset temperature is 55 °C (i.e., degrees Celsius). Alternatively, the first preset temperature can also be set to other suitable temperatures higher or lower than 55 °C, such as 54 °C, 56 °C, etc. When the judgment result is no, it means that the temperature in the first chamber 1111 does not exceed the first preset temperature and no intervention is required, so step S10 is repeatedly executed. When the judgment result is yes, the control method proceeds to step S31, that is, the actual rotational speed of the upper fan 1141 is obtained. Then, it is judged whether the actual rotational speed of the upper fan 1141 is less than the preset maximum rotational speed. In one or more embodiments, the preset maximum rotational speed is the rated maximum rotational speed of the upper fan 1141. For example, if the rated maximum rotational speed of the upper fan 1141 is 1000 r / min (i.e., revolutions per minute), then the preset maximum rotational speed is 1000 r / min. Alternatively, the preset maximum rotational speed can also be set to other suitable values smaller than the rated maximum rotational speed. For example, the rated maximum rotational speed of the upper fan 1141 is 1000 r / min, and the preset maximum rotational speed is 950 r / min. When the judgment result is yes, it means that the actual rotational speed of the upper fan 1141 has not reached the preset maximum rotational speed at this time, so the upper fan 1141 is controlled to increase its rotational speed (i.e., step S33). After step S33 is completed, the control method repeatedly executes step S10, that is, the actual temperature of the first chamber 1111 is obtained again.

[0041] Continue to refer to Figure 4, after performing step S32, when the judgment result is negative, it indicates that the actual speed of the upper blower 1141 has reached the preset maximum speed at this time. Then, step S34 is executed, that is, the upper blower 1141 is maintained to operate at the preset maximum speed. Next, the control method proceeds to step S35, that is, after a preset time period, the actual temperature of the first chamber 1111 is acquired again. In one or more embodiments, the preset time period is 5 min (i.e., minutes). Alternatively, the preset time period can also be set to other suitable time periods longer or shorter than 5 min, such as 4 min, 6 min, etc. Then, it is judged whether the newly obtained actual temperature is greater than the first preset temperature (i.e., step S35). When the judgment result is negative, it indicates that the actual temperature in the first chamber 1111 is lower than or equal to the first preset temperature at this time, and the control method ends. After the control method ends, the control method can repeat step S10 to continuously monitor the actual temperature in the first chamber 1111. When the judgment result is positive, it indicates that the actual temperature in the first chamber 1111 is still relatively high at this time. Then, step S37 is executed to control the air inlet 1114 on the housing 111 of the outdoor unit 110 to open, so as to quickly cool down and dissipate heat from the electronic control component 116. The air inlet 1114 can be controlled to open or close by means of a damper 1115 arranged thereon.

[0042] Figure 5 It is a schematic flowchart of the second embodiment of the control method for an air conditioner according to the present invention. As Figure 5As shown, in one or more embodiments, after the air inlet 1114 is opened, the control method of the present invention for the air conditioner 100 executes step S40, that is, after a preset time period, the actual temperature of the first chamber 1111 is obtained again. In one or more embodiments, the preset time period is 5 minutes. Alternatively, the preset time period can also be set to other suitable time periods longer or shorter than 5 minutes, such as 4 minutes, 6 minutes, etc. Then, the newly obtained actual temperature is compared with the second preset temperature. That is, it is judged whether the newly obtained actual temperature is greater than the second preset temperature. Among them, the second preset temperature is less than the first preset temperature. In one or more embodiments, the second preset temperature is 45°C. Alternatively, the second preset temperature can also be set to other suitable temperatures higher or lower than 45°C, such as 44°C, 46°C, etc. When the judgment result is yes, it indicates that the actual temperature in the first chamber 1111 is still relatively high at this time. Therefore, the control method executes step S42, that is, keeps the air inlet 1114 open. Alternatively, the control method can also control the air inlet 1114 to increase the opening degree so that more external air can enter the first chamber 1111, thereby quickly reducing the temperature of the electronic control component 116. After step S42 is completed, the control method repeats step S40, that is, after a preset time period, the actual temperature of the first chamber 1111 is obtained again. After step S41 is executed, when the judgment result is no, it indicates that the actual temperature in the first chamber 1111 is already less than or equal to the second preset temperature at this time, then the air inlet 1114 is controlled to close to ensure the heat exchange efficiency of the outdoor heat exchanger 113. After step S43 is completed, the control method ends. After the control method ends, the control method can repeat step S10 to continuously monitor the actual temperature of the first chamber 1111.

[0043] It should be noted that the parts not mentioned in the second embodiment can be configured the same as those in the first embodiment, and will not be elaborated here.

[0044] The present invention also provides a computer-readable storage medium (not shown in the figure). A computer program is stored on the computer-readable storage medium, and the computer program can be executed by a processor to implement the control method for the air conditioner 100 according to any one of the above embodiments.
