[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, 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 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 making creative work are within the scope of protection of this application.

[0017] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0018] In order to solve the problem in the prior art that the automatic adjustment of the heat exchange effect of the unit according to the current ambient temperature takes a long time and leads to poor user experience, the present application provides a control method for air conditioning equipment, such as Figure 1 As shown, the steps of the method include:

[0019] Step 101, obtaining a first temperature corresponding to the air-conditioning device, wherein the first temperature includes the indoor temperature and outdoor temperature of the environment in which the air-conditioning device is located, and a set temperature of the air-conditioning device;

[0020] In the embodiment of the present application, the air conditioner is installed in different environments, and the corresponding indoor and outdoor temperatures in the same time period are different. For example, if the outdoor unit is in a small space with poor ventilation, the outdoor temperature is higher than that in a spacious space with good ventilation. Therefore, the temperature set for the air conditioner is different under different indoor and outdoor temperatures.

[0021] Step 102, comparing the first temperature with the recorded data; wherein the recorded data includes multiple groups of data, each group of data includes a second temperature and an operating parameter of the air-conditioning device corresponding to the second temperature; each second temperature includes an indoor temperature, an outdoor temperature and a set temperature of the air-conditioning device having a mapping relationship;

[0022] In a specific example, the multiple groups of data in the recorded data respectively record the operating parameters corresponding to the set temperature of the corresponding air-conditioning equipment at different indoor and outdoor temperatures. For example, when the outdoor temperature is 3°C, the indoor temperature is 5°C, and the current set temperature of the air-conditioning equipment is 28°C, then the corresponding operating parameters required at this time are an electronic expansion valve opening of 160 steps, a compressor frequency of 90Hz, and a fan frequency of 43Hz. The operating parameters can directly provide the demand for an air-conditioning set temperature of 28°C, and there is no need for the air-conditioning equipment to automatically adjust the operating parameters after it is set to 28°C. The above is just an example to illustrate that the operating parameters corresponding to different ambient temperatures and set temperatures of air-conditioning equipment are different, and the corresponding operating parameters are operating parameters that can directly meet user needs.

[0023] It should be noted that the indoor temperature, outdoor temperature and the set temperature of the air-conditioning device in the second temperature in the embodiment of the present application can be a specific value, such as the outdoor temperature is 3°C, the indoor temperature is 5°C, and the set temperature of the current air-conditioning device is 28°C; it can also be a range of values, such as the outdoor temperature is 1-5°C, the indoor temperature is 5-10°C, and the set temperature is 26 to 30°C. Therefore, comparing the first temperature with the recorded data in the embodiment of the present application can refer to whether the second temperature is completely consistent with the first temperature, that is, the first temperature includes an outdoor temperature of 3°C, an indoor temperature of 5°C, and the set temperature of the current air-conditioning device is 28°C, and the second temperature is also an outdoor temperature of 3°C, an indoor temperature of 5°C, and the set temperature of the current air-conditioning device is 28°C. Alternatively, comparing the first temperature with the recorded data may refer to whether the first temperature falls within the range of the second temperature, such as the first temperature is 3°C for outdoor temperature, 5°C for indoor temperature, and the current set temperature of the air conditioner is 28°C. If the second temperature is 1-5°C for outdoor temperature, 5-10°C for indoor temperature, and the set temperature is 26-30°C, then the first temperature falls within the range of the second temperature. Because when the current ambient temperature does not change much, the set temperature is also not much different, and the operating parameters of the air conditioner are basically unchanged. The above method can quickly find the matching operating parameters, thereby quickly controlling the operation of the air conditioner.

[0024] Step 103: When there is a second temperature matching the first temperature in the recorded data, control the operation of the air conditioning device based on the operation parameters corresponding to the second temperature.

[0025] Through the above steps 101 to 103, after obtaining the indoor temperature, outdoor temperature and set temperature of the environment where the air-conditioning device is located, the first temperature obtained is compared with the recorded data, so as to find the second temperature matching it from the recorded data, and then control the operation of the air-conditioning device according to the operating parameters corresponding to the matching second temperature. It can be seen that in the embodiment of the present application, after obtaining the first temperature of the current environment, the corresponding operating parameters can be quickly found to operate the air-conditioning device, and the air-conditioning device does not need to be automatically adjusted in the current environment to find the appropriate operating parameters, which can not only save energy consumption, but also further improve the user experience, and solve the problem of the prior art that the heat exchange effect of the unit is automatically adjusted according to the current ambient temperature, which takes a long time and leads to poor user experience.

[0026] In the embodiment of the present application, the operating parameters of the air-conditioning equipment may refer to the opening of the electronic expansion valve of the air-conditioning equipment, the fan frequency of the air-conditioning equipment, and the compressor frequency of the air-conditioning equipment. The pressure of the air-conditioning equipment can be corrected by the above operating parameters. Based on this, the method of controlling the operation of the air-conditioning equipment based on the operating parameters corresponding to the second temperature involved in step 103 in the embodiment of the present application may include:

[0027] Step 11, based on the operating parameters, adjusting at least one of the following operating parameters to bring the pressure of the compressor of the air-conditioning equipment to the target pressure: the opening of the electronic expansion valve of the air-conditioning equipment, the fan frequency of the air-conditioning equipment, and the compressor frequency of the air-conditioning equipment.

[0028] Among them, the target pressure in the embodiment of the present application includes a target high pressure and a target low pressure, that is, in a specific application scenario, the target high pressure and the target low pressure are obtained by correcting the basic high pressure and the basic low pressure. Specifically, the target pressure can be directly obtained by correcting the operating parameters in the recorded data, that is, the opening of the electronic expansion valve of the air-conditioning equipment, the fan frequency of the air-conditioning equipment, and the compressor frequency of the air-conditioning equipment, without the need for automatic adjustment of the air-conditioning equipment, which takes a long time to find the appropriate operating parameters for pressure correction.

[0029] In different environments, the different operating modes of the air-conditioning equipment have different corresponding adjustment methods. The following will further explain how to adjust the air-conditioning equipment in different environments when it is in heating mode and cooling mode.

[0030] When the air conditioner is in the heating mode, the method of adjusting at least one of the following operating parameters based on the operating parameters involved in step 11 to make the pressure of the compressor of the air conditioner reach the target pressure: the opening of the electronic expansion valve of the air conditioner, the fan frequency of the air conditioner, and the compressor frequency of the air conditioner may include:

[0031] Step 21, when the return air temperature of the air conditioner decreases, increasing the opening of the electronic expansion valve, reducing the compressor frequency, and increasing the fan frequency in the air conditioner, so that the high pressure of the compressor of the air conditioner increases to a first target high pressure;

[0032] Step 22, when the return air temperature rises, reduce the opening of the electronic expansion valve, increase the compressor frequency and reduce the fan frequency in the air-conditioning equipment, so as to reduce the high pressure of the compressor of the air-conditioning equipment to a second target high pressure.

[0033] It should be noted that the return air temperature in the air conditioning equipment refers to the air temperature delivered from the return air outlet of the air conditioning. It can be seen that in the heating mode, if the return air temperature decreases, it means that the temperature of the outdoor unit decreases, and the outdoor unit is prone to frost, resulting in poor heating effect of the outdoor unit. Therefore, it is necessary to increase the high pressure, that is, it is necessary to increase the opening of the electronic expansion valve, reduce the compressor frequency, and increase the fan frequency in the air conditioning equipment, so that the high pressure of the compressor of the air conditioning equipment is increased to the first target high pressure, which can prevent the outdoor unit from frosting while meeting the needs of users. If the return air temperature increases, it means that the temperature of the outdoor unit increases, and the outdoor unit is not easy to frost at this time. If the output of the air conditioning equipment is higher than the user's demand at this time, the high pressure can be appropriately reduced, that is, the opening of the electronic expansion valve is reduced, the compressor frequency is increased, and the fan frequency in the air conditioning equipment is reduced, so that the high pressure of the compressor of the air conditioning equipment is reduced to the second target high pressure. In this way, energy consumption can be reduced while meeting user needs.

[0034] When the air conditioner is in cooling mode, the method of adjusting at least one of the following operating parameters based on the operating parameters involved in step 11 to make the pressure of the compressor of the air conditioner reach the target pressure: the opening of the electronic expansion valve of the air conditioner, the fan frequency of the air conditioner, and the compressor frequency of the air conditioner may further include:

[0035] Step 31, when the return air temperature of the air conditioner increases, the opening of the electronic expansion valve is increased, the compressor frequency is increased, and the frequency of the external and internal fans of the air conditioner is increased, so that the low pressure of the compressor of the air conditioner is reduced to the first target low pressure;

[0036] Step 32, when the return air temperature decreases, reducing the opening of the electronic expansion valve, reducing the compressor frequency and reducing the fan frequency in the air-conditioning device, so as to increase the low pressure of the compressor of the air-conditioning device to a second target low pressure.

[0037] It can be seen that in the cooling mode, if the return air temperature rises, it indicates that the temperature of the outdoor unit has risen and the heat dissipation effect of the outdoor unit is not good. Therefore, it is necessary to reduce the low pressure to make the cooling effect of the air-conditioning equipment better, that is, increase the opening of the electronic expansion valve, increase the compressor frequency, and increase the fan frequency inside and outside the air-conditioning equipment, so that the low pressure of the compressor of the air-conditioning equipment is reduced to the first target low pressure, and the cooling effect of the air-conditioning equipment is improved to quickly meet the needs of users. If the return air temperature decreases, it indicates that the outdoor unit can dissipate heat well at this time. If the output of the air-conditioning equipment is higher than the user's demand at this time, the low pressure can be appropriately increased, that is, reduce the opening of the electronic expansion valve, reduce the compressor frequency, and reduce the fan frequency inside the air-conditioning equipment, so that the low pressure of the compressor of the air-conditioning equipment is increased to the second target low pressure. In this way, energy consumption can be reduced while meeting user needs.

[0038] The above-mentioned embodiments of the present application are all control processes of the air-conditioning device under different circumstances after the recorded data has been obtained. Prior to this, it is necessary to record the operating parameters of the air-conditioning device according to the operating rules of the air-conditioning device in the current environment to obtain the recorded data. Therefore, before obtaining the first temperature corresponding to the air-conditioning device, such as Figure 2 As shown, the method steps of the embodiment of the present application also include:

[0039] Step 201, determining a first indoor temperature, a first outdoor temperature of the environment in which the device is located, and a first set temperature of the air conditioning device;

[0040] Step 202, after the air conditioning device is running, adjusting the operating parameters of the air conditioning device to the first operating parameters according to the change of the return air temperature of the air conditioning device, so that the compressor pressure of the air conditioning device reaches the target pressure, wherein the set temperature of the air conditioning device is satisfied when the compressor pressure is the target pressure;

[0041] Step 203, recording the first indoor temperature, the first outdoor temperature, the first set temperature and the first operating parameter as a group of data and saving them in the recorded data.

[0042] It can be seen that through the above steps 201 to 203, when the ambient temperature of the indoor and outdoor units and the user-set temperature are the same, the temperature and humidity changes of the return air will also be different. While ensuring the appropriate basic high pressure (low pressure) output range, the fan frequency and the opening of the indoor and outdoor unit valves can be adjusted in advance to adjust the high pressure (low pressure) correction and increase or decrease the system high pressure (low pressure). That is, in the automatic adjustment process of the air-conditioning equipment in the current environment, the final operating parameters of the air-conditioning equipment in the current environment can be directly obtained, that is, the operating parameters after the basic high pressure or basic low pressure is corrected. Next time, if it is the same environment (indoor and outdoor temperatures match or are close), and the set temperature is also matched or close, the operation of the air-conditioning equipment can be directly controlled based on the previously recorded operating parameters.

[0043] In a specific example, the recorded data includes multiple sets of data corresponding to multiple different situations. The statistics are automatically collected by the user when using the air-conditioning device, without the need for manual recording by the user. That is, in a certain environment, if the air-conditioning device can operate stably, the indoor and outdoor temperatures, set temperatures and operating parameters of the air-conditioning device are recorded.

[0044] Furthermore, how to adjust the operating parameters of the air-conditioning equipment according to the return air temperature can be further explained according to different operating modes.

[0045] When the air conditioning device is in the heating mode, the method of adjusting the operating parameters of the air conditioning device according to the change of the return air temperature of the air conditioning device involved in the above step 202 may further include:

[0046] Step 41, when the return air temperature decreases, increasing the opening of the electronic expansion valve, reducing the compressor frequency, and increasing the fan frequency in the air conditioning equipment;

[0047] Step 42, when the return air temperature increases, reduce the opening of the electronic expansion valve, increase the compressor frequency, and reduce the fan frequency in the air conditioning equipment.

[0048] It can be seen that in the heating mode, if the return air temperature decreases, it means that the temperature of the outdoor unit decreases, and the outdoor unit is prone to frost, resulting in poor heating effect of the outdoor unit. Therefore, it is necessary to increase the high pressure, that is, increase the opening of the electronic expansion valve, reduce the compressor frequency, and increase the fan frequency in the air-conditioning equipment, so as to prevent the outdoor unit from frosting while meeting the needs of users. If the return air temperature increases, it means that the temperature of the outdoor unit increases, and the outdoor unit is not prone to frost. If the output of the air-conditioning equipment is higher than the user's demand, the high pressure can be appropriately reduced, that is, reduce the opening of the electronic expansion valve, increase the compressor frequency, and reduce the fan frequency in the air-conditioning equipment to meet the user's needs.

[0049] When the air conditioner is in cooling mode, the method of adjusting the operating parameters of the air conditioner according to the change of the return air temperature of the outdoor unit of the air conditioner involved in step 202 may further include:

[0050] Step 51, when the return air temperature rises, increasing the opening of the electronic expansion valve, increasing the compressor frequency, and increasing the external and internal fan frequencies of the air conditioning equipment;

[0051] Step 52, when the return air temperature decreases, reducing the opening of the electronic expansion valve, reducing the compressor frequency, and reducing the fan frequency in the air conditioning equipment.

[0052] It can be seen that in the cooling mode, if the return air temperature rises, it means that the temperature of the outdoor unit rises and the heat dissipation effect of the outdoor unit is not good. Therefore, it is necessary to reduce the low pressure to make the cooling effect of the air-conditioning equipment better, that is, increase the opening of the electronic expansion valve, increase the compressor frequency, and increase the fan frequency inside and outside the air-conditioning equipment to improve the cooling effect of the air-conditioning equipment to quickly meet user needs. If the return air temperature decreases, it means that the outdoor unit can dissipate heat better at this time. If the output of the air-conditioning equipment is higher than the user's demand at this time, the low pressure can be appropriately increased, that is, reduce the opening of the electronic expansion valve, reduce the compressor frequency, and reduce the fan frequency inside the air-conditioning equipment to meet user needs.

[0053] The present application is explained below in conjunction with the specific implementation methods of the embodiments of the present application. Since users seldom move the installation location of the air conditioner after installation, the air conditioning system can automatically adjust the heat exchange effect of the unit by detecting the degree of heat exchange of the outdoor environment, and the outdoor unit of the air conditioner can detect the difference in the environment of the outdoor unit through the difference and change of the temperature and humidity of the return air. In this way, big data recording is performed and the operating rules of the indoor and outdoor units of the air conditioner are learned due to the operating characteristics of the space in which they are located and the different seasons of the environment for pre-adjustment, so as to achieve the effect of energy saving and increased comfort. Based on this, this specific implementation method provides a method for pre-adjusting the output of the unit according to the installation location of the unit.

[0054] The specific implementation is explained below through the following specific examples:

[0055] Example 1:

[0056] In cooling conditions, if the outdoor unit is in a small space, the ventilation effect is poor, and the fan continues to rotate, the heat around the outdoor unit cannot be dissipated well, and the heat exchange will become poor. After recording the system's operating parameters at this time, the target low pressure can be lowered in advance to make low pressure corrections. If the outdoor unit is in an open space, such as on the rooftop with good ventilation, the heat exchange effect may even increase. At this time, the target low pressure can be increased in advance to make low pressure corrections.

[0057] For example, in a small space with poor ventilation, the system can detect that the initial return air temperature is 35°C through the temperature sensor package, but because the heat dissipation of the outdoor unit is very poor, a certain amount of heat will accumulate around the outdoor unit, and the return air temperature will gradually rise to 38°C, 40°C, etc. At this time, the system usually detects the increase in return air temperature and adjusts the system low pressure by increasing the frequency of the outdoor fan, increasing the frequency of the compressor, and increasing the opening of the electronic expansion valve. For example, if the initial low pressure is 8°C, the low pressure may be 6 degrees after adjustment to meet the user's cooling needs. However, after the user has this learning function, the low pressure can be directly set to 6°C at the beginning of the system startup, which reduces the process of continuous adjustment of the system and improves a certain degree of comfort.

[0058] Example 2:

[0059] During heating, if the outdoor unit is in an area with high humidity, the high humidity will directly affect the outdoor unit and make it easier to frost, which will cause the outdoor unit heating effect to deteriorate. In this case, after recording the system operating parameters at this time, the temperature and humidity of the outdoor unit return air are different. The next time the heating is performed at the same humidity, the opening of the outdoor unit electronic expansion valve can be increased in advance, the compressor frequency can be reduced, and the speed of the indoor fan can be increased to reduce the high pressure, thereby preventing the outdoor unit from frosting and affecting the heating effect.

[0060] Frosting of the unit will greatly affect the heating effect of the unit, and there are many areas with high humidity that are more prone to frost. When the unit records that the unit used by the user is in an area with high humidity and has frosting parameters, such as high pressure of 52°C, electronic expansion valve opening of 160 steps, air humidity of 98%, compressor frequency of 90HZ, fan frequency of 43HZ, etc., after the system collects the information of the unit when it is frosted, the next time it encounters this condition, the system will automatically adjust the system to a state that is not easy to frost by reducing the frequency, increasing the opening of the electronic expansion valve, etc., thereby reducing the impact on the heating effect.

[0061] It can be seen that in the specific implementation of the present application, if the system operating parameters at this time are recorded, under the same ambient temperature of the indoor and outdoor units and the user set temperature, while ensuring the appropriate basic low-pressure output range, the fan frequency and the opening of the indoor and outdoor unit valves can be adjusted in advance to adjust the high pressure (low pressure) correction, increase or reduce the system high pressure (low pressure). This can avoid repeated adjustment of operating parameters, resulting in the inability to quickly achieve cooling or heating effects, and can even avoid some special situations, such as frosting of the outdoor unit. Through the embodiment of the present application, human comfort is guaranteed and energy consumption can be saved.

[0062] Corresponding to the above Figure 1 , the present application embodiment provides a control device for air conditioning equipment, such as Figure 3 As shown, the device comprises:

It can be seen that in the embodiment of the present application, after obtaining the first temperature of the current environment, the corresponding operating parameters can be quickly found to operate the air-conditioning device, and the air-conditioning device does not need to be automatically adjusted in the current environment to find the appropriate operating parameters, which can not only save energy consumption, but also further improve the user experience, and solve the problem of the prior art that the heat exchange effect of the unit is automatically adjusted according to the current ambient temperature, which takes a long time and leads to poor user experience.
