Description

Technical Field

[0001] The present invention relates to the technical field of mobile air conditioners, and in particular to a control method of a mobile air conditioner and a mobile air conditioner. Background Art

[0002] With the development of economy, people's living standards have been greatly improved, and the functional requirements for air conditioners have been continuously improved. Camping can not only increase the closeness between people and nature, but also relieve the pressure of people's daily life. It has become a fashionable outdoor activity. However, in summer, the sunshine is sufficient and the weather is hot. If the tent is completely closed, the internal temperature will rise to more than 40℃, which is extremely harmful to human health. For this reason, an integrated mobile air conditioner is needed to cool the air in the tent and improve the comfort of people's outdoor camping.

[0003] A mobile air conditioner is an air conditioner that can be moved at will. The world's first mobile air conditioner was born in 1986 by Delonghi Company of Italy. The machine is equipped with a compressor, exhaust fan, electric heater, evaporator, air-cooled finned condenser and other devices. The machine body is equipped with a power plug and the base of the machine body is equipped with four casters, which can make the air conditioner move at will. From the appearance, the style and size of the air conditioner are similar to those of the air conditioner fan, and it has the individual charm of fashion, lightness and dexterity.

[0004] From a technical point of view, the power and cooling capacity of mobile air conditioners are basically the same as those of ordinary air conditioners. The difference lies in the air duct circulation design. The air volume circulation of ordinary air conditioners is aimed at indoor air circulation, while mobile air conditioners reduce the indoor air temperature while sucking in fresh air from the outside. In essence, air conditioners use outdoor compressors to exchange heat and cool, while mobile air conditioners do this alone with the indoor unit.

[0005] However, the diameter of the mobile air conditioner is small, with an inner diameter of only 5mm. When welding the pipes, welding blockage will occur, and it is difficult to detect. Moreover, it is impossible to observe whether there are tiny holes during welding that cause refrigerant leakage. Only when the whole machine is running for a long time will the above problems be revealed, which will have a great impact on subsequent use. In addition, after the user sets the mode and wind speed, the air outlet temperature may be difficult to reach the temperature the user wants. Summary of the invention

[0006] The purpose of the present invention is to overcome the above technical deficiencies and provide a control method for a mobile air conditioner and a mobile air conditioner to solve the problem in the related art that when welding blockage occurs in the pipeline of the mobile air conditioner, it is impossible to troubleshoot.

[0029] Preferably, the detecting the operating status of the compressor includes:

[0030] Detect the operating current of the compressor;

[0031] If the operating status shows that the compressor is not started, it is determined that the pipeline of the air conditioner is blocked by welding. Specifically, if the working current is lower than the threshold current after a preset time, it is determined that the pipeline of the air conditioner is blocked by welding.

[0032] Preferably, the detecting the operating status of the compressor includes:

[0048] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0049] Embodiment 1

[0050] Figure 1 is a flow chart showing a method for controlling a mobile air conditioner according to an exemplary embodiment. Figure 1 , the control method comprises:

[0051] Step S11, after the air conditioner turns on the cooling mode, the operating state of the compressor is detected;

[0052] Step S12: if the operating status shows that the compressor is not started, it is determined that the pipeline of the air conditioner is blocked by welding;

[0053] Step S13: If the operating status shows that the compressor is started normally, it is determined that no welding blockage occurs to the air conditioner pipeline.

[0054] It should be noted that the technical solution provided in this embodiment is loaded into the controller of a mobile air conditioner for operation in specific practice. The mobile air conditioner includes: an integrated mobile air conditioner and a split mobile air conditioner.

[0055] It is understandable that, taking the integrated mobile air conditioner as an example, the integrated mobile air conditioner is the best choice for people when camping because of its convenient portability, small size and high cooling capacity. However, the pipe diameter of the air conditioner is very small, only 5mm, and it is very easy to be welded and blocked, but this phenomenon is not easy to detect. It can only be judged by the operating status of the compressor during operation.

[0056] In specific practice, the detection of the operating state of the compressor may be:

[0057] Detect the working noise of the compressor;

[0058] If the operating status shows that the compressor is not started, it is determined that the pipeline of the air conditioner is welded and blocked. Specifically, if the working noise is 0 after a preset time, it is determined that the pipeline of the air conditioner is welded and blocked.

[0059] In specific practice, the detection of the operating state of the compressor may be:

[0060] Detect the operating current of the compressor;

[0061] If the operating status shows that the compressor is not started, it is determined that the air conditioner pipe is blocked by welding. Specifically, if the working current is lower than the threshold current after a preset period of time (the threshold current is set according to historical experience or experimental data, for example, set to 3A), it is determined that the air conditioner pipe is blocked by welding.

[0062] In specific practice, the detection of the operating state of the compressor may be:

[0063] Detect the shell temperature of the compressor;

[0064] If the operating status shows that the compressor is not started, it is determined that the air conditioner pipe is blocked by welding. Specifically, if the shell temperature is lower than the threshold temperature (the threshold temperature is set according to historical experience or experimental data, for example, set to 3°C) after a preset period of time, it is determined that the air conditioner pipe is blocked by welding.

[0065] It can be understood that the technical solution provided in this embodiment checks the operating status of the compressor and determines whether the pipes of the air conditioner are blocked by welding, thereby solving the technical problem in the prior art that it is impossible to check whether the pipes of the air conditioner are blocked by welding, thereby improving the operating reliability of the mobile air conditioner and reducing the difficulty of after-sales maintenance.

[0066] Embodiment 2

[0067] Figure 2 is a flow chart showing a method for controlling a mobile air conditioner according to another exemplary embodiment. Figure 2 , the control method comprises:

[0068] Step S21, after the air conditioner turns on the cooling mode, the operating state of the compressor is detected;

[0069] Step S22: if the operating status shows that the compressor is not started, it is determined that the pipeline of the air conditioner is blocked by welding;

[0070] Step S23: if the operating status shows that the compressor is started normally, it is determined that the air conditioner pipeline is not blocked by welding;

[0071] Step S24: if it is determined that the air conditioner pipeline is not blocked by welding, the exhaust temperature of the compressor is detected;

[0072] Step S25: If the exhaust temperature is greater than a preset temperature (the preset temperature is set according to experimental data or historical experience, for example, 80°C), it is determined that there are holes in the air-conditioning pipeline, causing refrigerant leakage; otherwise, it is determined that there are no holes in the air-conditioning pipeline.

[0073] It should be noted that the technical solution provided in this embodiment is loaded into the controller of a mobile air conditioner for operation in specific practice. The mobile air conditioner includes: an integrated mobile air conditioner and a split mobile air conditioner.

[0074] It is understandable that, taking the integrated mobile air conditioner as an example, the integrated mobile air conditioner is the best choice for people when camping because of its portability, small size and high cooling capacity. However, the air conditioning pipeline is very small, only 5mm, and it is very easy to get welded and blocked, but this phenomenon is not easy to detect. It can only be judged by the operating status of the compressor during operation. At the same time, because the pipeline is thin, in order to avoid excessive solder and welding blockage, the welder will not use too much solder when welding the pipeline, which may cause tiny holes in the pipeline and cause refrigerant leakage. However, the amount of refrigerant leakage is small and difficult to observe. For this reason, the refrigerant leakage can be detected by observing the exhaust temperature.

[0075] It can be understood that the technical solution provided in this embodiment checks the operating status of the compressor and determines whether the pipes of the air conditioner are blocked by welding, thereby solving the technical problem in the prior art that it is impossible to check whether the pipes of the air conditioner are blocked by welding, thereby improving the operating reliability of the mobile air conditioner and reducing the difficulty of after-sales maintenance.

[0076] Furthermore, the technical solution provided in this embodiment determines whether there are tiny holes in the air-conditioning pipes by checking the exhaust temperature of the compressor, thereby solving the technical problem in the prior art that it is impossible to check whether the air-conditioning pipes have leaking welds or cold welds, further improving the operating reliability of the mobile air-conditioner and reducing the difficulty of after-sales maintenance.

[0077] Embodiment 3

[0078] Figure 3is a flow chart showing a method for controlling a mobile air conditioner according to another exemplary embodiment. Figure 3 , the control method comprises:

[0079] Step S31, after the air conditioner turns on the cooling mode, receiving the windshield information set by the user and the target air outlet temperature set by the user;

[0080] Step S32, detecting the operating state of the compressor; if the operating state shows that the compressor is not started, determining that welding blockage occurs in the pipeline of the air conditioner; otherwise, determining that welding blockage does not occur in the pipeline of the air conditioner;

[0081] Step S33: if it is determined that the pipeline of the air conditioner is not blocked by welding, the exhaust temperature of the compressor is detected; if the exhaust temperature is greater than a preset temperature (the preset temperature is set according to experimental data or historical experience values, for example, 80° C.), it is determined that there is a hole in the pipeline of the air conditioner, causing refrigerant leakage; otherwise, it is determined that there is no hole in the pipeline of the air conditioner;

[0082] Step S34: if it is determined that there is no hole in the air conditioning pipeline, measure the actual air outlet temperature of the air conditioning; and adjust the speed of the internal and external fans according to the difference between the actual air outlet temperature and the target air outlet temperature.

[0083] It should be noted that the technical solution provided in this embodiment is loaded into the controller of a mobile air conditioner for operation in specific practice. The mobile air conditioner includes: an integrated mobile air conditioner and a split mobile air conditioner.

[0084] In actual practice, there are three levels of windshield information, and their meanings are shown in Table 1 below:

[0085] Serial number letter meaning 1 X1 Low wind speed 2 X2 Stroke 3 X3 High windshield

[0086] Table 1

[0087] It is understandable that, taking the integrated mobile air conditioner as an example, the integrated mobile air conditioner is the best choice for people when camping because of its convenient portability, small size and high cooling capacity. However, the air conditioning pipeline is very small, only 5mm, and it is very easy to cause welding blockage, but this phenomenon is not easy to detect. It can only be judged by the operating status of the compressor during operation. At the same time, because the pipeline is thin, in order to avoid welding blockage caused by too much solder, the welder will not use too much solder when welding the pipeline, which may cause tiny holes in the pipeline and cause refrigerant leakage. However, the amount of refrigerant leakage is small and difficult to observe. For this reason, the refrigerant leakage can be detected by observing the exhaust temperature. In addition, after the mobile air conditioner on the market sets the mode and wind speed, the air outlet temperature of the air conditioner will remain constant, but this temperature is not necessarily suitable for the user. In order to increase user satisfaction, a new function of air outlet temperature is added, allowing users to adjust the air outlet temperature at will, which increases user satisfaction.

[0088] In specific practice, in step S34, adjusting the speed of the internal and external fans according to the difference between the actual air outlet temperature and the target air outlet temperature includes:

[0089] Under the condition of keeping the existing compressor frequency unchanged, adjusting the speed of the internal and external fans to increase according to the increase of the difference, including:

[0090] According to the increase of the difference, the speed of the internal and external fans can be increased in equal proportion (for example, for every 1°C difference between the actual outlet air temperature and the target outlet air temperature, the speed of the internal and external fans can be increased by 50r); or,

[0091] According to the increase of the difference, it increases linearly; or,

[0092] According to the increase of the difference, it increases in a multiple function.

[0093] See also Figure 3 , when the weather is hot, the user turns on the cooling mode and sets the wind speed according to his own feeling (X1-X3, different wind speeds and frequencies are different, which are finally set based on noise, fixed frequency and performance). Then the user sets the desired target air outlet temperature. If the compressor does not start at this time, it means that the pipeline has been blocked by welding. This is because after welding, the refrigerant cannot circulate, the compressor will idle, the suction and exhaust temperatures will rise rapidly, and finally trigger the compressor self-protection program, resulting in the compressor not running. If the compressor starts normally, the exhaust temperature is detected at any time (the detection frequency is 5 times within 1s. Since the compressor frequency increases very quickly, the corresponding frequency can be reached within 30s, and the exhaust temperature also tends to be stable at this time. In order to make the control more accurate, the detection needs to be more frequent, so the detection frequency is set to 5 times within 1s.), when the exhaust temperature is ≥80℃, it can be determined that the refrigerant has leaked (according to experimental measurements, the exhaust temperature is generally maintained between 76-78℃ during normal operation, but when the refrigerant leaks, the power consumption of the whole machine will increase, and the exhaust temperature of the compressor will also rise, and ≥80℃). If the exhaust temperature is normal, it can be detected whether the actual outlet air temperature reaches the target outlet air temperature. If the target outlet air temperature is not reached, the internal and external fan speeds can be increased by 50r for every 1°C difference between the two, which can increase the heat exchange of the evaporator and condenser, thereby reducing the outlet air temperature. This setting does not include the increase of the compressor frequency, because increasing the compressor frequency may reach the compressor frequency shielding point, resulting in increased noise and vibration, and in severe cases resonance will occur, reducing the performance of the pipeline.

[0094] It can be understood that the technical solution provided in this embodiment checks the operating status of the compressor and determines whether the pipes of the air conditioner are blocked by welding, thereby solving the technical problem in the prior art that it is impossible to check whether the pipes of the air conditioner are blocked by welding, thereby improving the operating reliability of the mobile air conditioner and reducing the difficulty of after-sales maintenance.

[0095] Furthermore, the technical solution provided in this embodiment determines whether there are tiny holes in the air-conditioning pipes by checking the exhaust temperature of the compressor, thereby solving the technical problem in the prior art that it is impossible to check whether the air-conditioning pipes have leaking welds or cold welds, further improving the operating reliability of the mobile air-conditioner and reducing the difficulty of after-sales maintenance.

[0096] Furthermore, the technical solution provided in this embodiment allows users to adjust the air outlet temperature at will by adding a new function of setting the target air outlet temperature, thereby increasing user satisfaction.
