[0002] At present, the remote control solution used on smart air conditioners generally pre-sets multiple modes in the user's remote control APP. The user needs to manually select the corresponding operating mode. For example, after exercising, the user sets the air conditioner to cooling, low temperature, and high wind. However, after the user selects the operating mode and runs it for a period of time, the user's body often gradually feels uncomfortable and needs to manually select again, resulting in unintelligent operation selection, inability to perform intelligent remote control of the air conditioner, and inability to consider user comfort at the same time. Summary of the invention

[0003] In order to solve the above technical problems, an embodiment of the present invention provides an air conditioning control system, which can improve the user's comfort while realizing remote control of the air conditioner.

[0009] The cloud platform sends control instructions to the control screen according to the received recommended temperature, recommended humidity, recommended wind speed and the current operating status of the air-conditioning equipment.

[0010] Through the recommended temperature, recommended humidity and recommended wind speed sent by the remote server, the cloud platform can generate control instructions based on the recommended parameters and the current operating status of the air-conditioning equipment, and realize remote control of the air-conditioning equipment through the control panel.

[0011] Furthermore, the recommended temperature, recommended humidity and recommended wind speed can represent the user's comfort, so that the user experience can be met in real time.

[0012] In some embodiments of the present application, in order to achieve intelligent integrated control of air-conditioning equipment, the cloud platform issues control commands that integrate multiple factors, and the control instructions include mode and temperature control instructions, humidity control instructions, and wind speed control instructions.

[0013] In some embodiments of the present application, the cloud platform further performs the following processing:

[0014] Determine whether the recommended temperature is consistent with the current temperature. If so, the mode and temperature control instruction enables the air-conditioning device to maintain the current mode and temperature control. If not, determine the switching mode based on the current outdoor ambient temperature and the recommended temperature, and determine whether the operating mode of the air-conditioning device is consistent with the switching mode. If so, the mode and temperature control instruction uses the recommended temperature as the indoor target temperature to control the temperature of the air-conditioning device. If not, the mode and temperature control instruction enables the air-conditioning device to switch to the switching mode, and uses the recommended temperature as the indoor target temperature to control the temperature of the air-conditioning device.

[0015] Through mode and temperature control instructions, remote mode and temperature control of air-conditioning equipment can be achieved.

[0016] In some embodiments of the present application, the cloud platform further performs the following processing:

[0017] Determine whether the recommended humidity is consistent with the current humidity. If so, the humidity control command enables the air-conditioning device to maintain the current humidity control. If not, the humidity control command enables the air-conditioning device to control the humidity of the air-conditioning device with the recommended humidity as the indoor target humidity.

[0018] Through humidity control instructions, remote humidity control of air-conditioning equipment can be achieved.

[0019] In some embodiments of the present application, the cloud platform further performs the following processing:

[0020] Determine whether the recommended wind speed is consistent with the current wind speed. If so, the wind speed control instruction enables the air-conditioning device to maintain the current wind speed control. If not, the wind speed control instruction enables the air-conditioning device to control the wind speed of the air-conditioning device with the recommended wind speed as the indoor target wind speed.

[0021] Through wind speed control instructions, remote wind speed control of air-conditioning equipment can be achieved.

[0022] In some embodiments of the present application, the switching mode is determined according to the outdoor ambient temperature and the recommended temperature, specifically:

[0023] Query a preset database and determine a switching mode according to the outdoor ambient temperature and the recommended temperature;

[0025] In some embodiments of the present application, the switching modes include a cooling mode, a heating mode and an air supply mode.

[0026] In some embodiments of the present application, the wind speed control instruction enables the air conditioner to control the wind speed of the air conditioner with the recommended wind speed as the indoor wind speed, specifically:

[0027] Obtaining an adjustable wind speed range of the air conditioning device;

[0028] The wind speed of the air conditioning device is gradually adjusted with a certain adjustment step length.

[0029] By gradually adjusting the wind speed, sudden changes in wind speed can be avoided to reduce user experience.

[0030] In some embodiments of the present application, the certain adjustment step is the minimum adjustment step of the wind speed of the air-conditioning equipment.

[0031] The wind speed is adjusted gradually with the smallest adjustment step, so that the wind speed can be adjusted while considering the user experience.

[0032] In some embodiments of the present application, the humidity control instruction enables the air-conditioning device to control the humidity of the air-conditioning device with the recommended humidity as the indoor target humidity, specifically:

[0033] When the current humidity is greater than the recommended humidity, the humidity control instruction is a dehumidification instruction, and the dehumidification instruction causes the air-conditioning device to enter a dehumidification mode.

[0047] [Basic operating principle of air conditioner]

[0048] The air conditioner performs the air conditioning cycle by using a compressor, condenser, expansion valve and evaporator. The air conditioning cycle includes a series of processes involving compression, condensation, expansion and evaporation to cool or heat the indoor space.

[0049] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0050] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0051] The outdoor unit of the air conditioner refers to the part of the refrigeration cycle including the compressor, outdoor heat exchanger and outdoor fan, the indoor unit of the air conditioner includes the indoor heat exchanger and indoor fan, and a throttling device (such as a capillary tube or an electronic expansion valve) can be provided in the indoor unit or the outdoor unit.

[0052] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner performs a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner performs a cooling mode.

[0053] Among them, the indoor heat exchanger and the outdoor heat exchanger are converted to serve as a condenser or an evaporator, generally using a four-way valve. Please refer to the settings of conventional air conditioners for details, which will not be elaborated here.

[0054] The refrigeration working principle of the air conditioner is: the operation of the compressor makes the indoor heat exchanger (in the indoor unit, it is the evaporator at this time) in an ultra-low pressure state, the liquid refrigerant in the indoor heat exchanger evaporates rapidly to absorb heat, and the wind blown out by the indoor fan is cooled by the indoor heat exchanger coil and becomes cold air blown into the room. The evaporated refrigerant is pressurized by the compressor and condensed into liquid under the high-pressure environment of the outdoor heat exchanger (in the outdoor unit, it is the condenser at this time), releasing heat, and dissipating the heat into the atmosphere through the outdoor fan. This cycle achieves the cooling effect.

[0055] The heating working principle of the air conditioner is as follows: the gaseous refrigerant is pressurized by the compressor, becomes a high-temperature and high-pressure gas, enters the indoor heat exchanger (the condenser at this time), condenses and liquefies to release heat, becomes a liquid, and heats the indoor air at the same time, thereby achieving the purpose of raising the indoor temperature. The liquid refrigerant is decompressed by the throttling device and enters the outdoor heat exchanger (the evaporator at this time), evaporates and absorbs heat to become a gas, and at the same time absorbs the heat of the outdoor air (the outdoor air becomes colder), becomes a gaseous refrigerant, and enters the compressor again to start the next cycle.

[0056] [Air conditioning control system]

[0057] See also Figure 1 and Figure 2 The air conditioning control system of the present application includes air conditioning equipment, a control screen terminal 10, a cloud platform 20 and a remote service terminal 30.

[0058] The air conditioning device includes an outdoor unit and an indoor unit, wherein the outdoor unit refers to the outdoor unit as described above, including a compressor, an outdoor heat exchanger, an outdoor fan and an outdoor expansion valve.

[0059] The indoor unit refers to the indoor unit as described above, including an indoor heat exchanger, an indoor fan and an indoor-side expansion valve.

[0060] The outdoor unit and the indoor unit are connected through pipes to achieve indoor air conditioning.

[0061] The control panel terminal 10 is connected to the air conditioning equipment for centralized control of the air conditioning equipment. The control panel terminal 10 can centrally control a plurality of outdoor units and a plurality of indoor units.

[0062] The cloud platform 20 communicates with the control panel terminal 10 through a gateway device, for example, and receives data of the air-conditioning equipment reported by the control panel terminal 10, such as the indoor temperature.

[0063] The remote server 30 receives the data of the air-conditioning equipment forwarded by the cloud platform 20 , and can send the recommended temperature, recommended humidity and recommended wind speed to the cloud platform 20 .

[0064] In some embodiments of the present application, obtaining the recommended temperature, recommended humidity, and recommended wind speed not only takes into account the data of the air-conditioning equipment, but also takes into account other factors that affect the user's comfort, such as individual differences among users (e.g., thermal sensation), regional climate, season, etc. Therefore, the recommended temperature, recommended humidity, and recommended wind speed are related to the user's comfort.

[0065] At present, in the field of thermal comfort research, air conditioning control methods are mainly based on the heat exchange model between humans and the environment or environmental parameters, relying on the thermal sensation votes (TSV) of a large number of people to establish air conditioning control methods.

[0066] With reference to the existing patent CN113339950A, a test device for an air conditioner is provided. By establishing a thermal comfort model between the hand temperature and the face temperature (measured by an infrared sensing device) and the TSV, control adjustment instructions are issued, for example, temperature adjustment, humidity adjustment, indoor wind speed adjustment, etc. of the air conditioner; and the existing patent CN113339952A also discloses establishing a thermal comfort model between skin temperature (such as hand temperature, face temperature, forehead temperature, ear temperature) and TSV.

[0067] Based on this, existing algorithms such as the random forest algorithm can be used to establish a thermal comfort model to obtain the recommended temperature, recommended humidity, and recommended wind speed.

[0068] The remote service end 30 receives the data of the air-conditioning equipment forwarded by the cloud platform 20 at set intervals (eg, 10 minutes), and sends down the recommended temperature, recommended humidity, and recommended wind speed.

[0069] The cloud platform 20 receives the recommended temperature, recommended humidity and recommended wind speed, generates a control instruction according to the current operating status of the air-conditioning equipment, and sends the control instruction to the control screen 10.

[0070] The control panel 10 forwards the information to the air-conditioning device, so that when the control instruction is consistent with the current operating state of the air-conditioning device, the current operating state is maintained; and when the control instruction is inconsistent with the current operating state, the air-conditioning device is controlled.

[0071] In some embodiments of the present application, when the air-conditioning equipment needs to be dehumidified, no instructions regarding the recommended temperature and recommended wind speed are issued, that is, the cloud platform 20 only issues a dehumidification instruction.

[0072] See also Figure 3 In some embodiments of the present application, according to the issued recommended temperature, recommended humidity and recommended wind speed, the control instructions include mode and temperature control instructions, humidity control instructions and wind speed control instructions.

[0073] As follows, the mode and temperature control instructions, the humidity control instructions and the wind speed control instructions will be described respectively, wherein the mode and temperature control instructions correspond to the recommended temperature, the humidity control instructions correspond to the recommended humidity, and the wind speed control instructions correspond to the recommended wind speed.

[0074] Mode and temperature control instructions

[0075] See also Figure 4 , after the cloud platform 20 receives the recommended temperature, it performs the following operations.

[0076] S1: Determine whether the recommended temperature is consistent with the current temperature. If so, proceed to S2; if not, proceed to S3.

[0077] Recommended temperature is the recommended target indoor temperature.

[0078] The current temperature is the actual temperature in the room.

[0079] The recommended temperature here can be a temperature value or a temperature range.

[0080] When the current temperature is equal to the temperature value indicating the recommended temperature or the current temperature is within the temperature range indicating the recommended temperature, it can be considered that the recommended temperature and the current temperature are consistent; otherwise, it is considered that the recommended temperature and the current temperature are inconsistent.

[0081] S2: Mode and temperature control instructions keep the air conditioning equipment in the current mode and temperature control.

[0082] When the recommended temperature is consistent with the current temperature, it means that the current temperature operating condition of the air-conditioning equipment meets the user's comfort requirements, and there is no need to adjust the temperature of the air-conditioning equipment.

[0083] Therefore, the mode and temperature control instructions at this time make the air conditioning device maintain the current mode and temperature control.

[0084] S3: Determine the switching mode based on the current outdoor ambient temperature and the recommended temperature.

[0085] When the recommended temperature and the current temperature are inconsistent, the indoor temperature needs to be adjusted. Before adjusting the indoor temperature, the switching mode needs to be determined.

[0086] As mentioned above, the recommended temperature is the recommended indoor target temperature.

[0087] In some embodiments of the present application, a preset database is established in advance, and the switching mode corresponding to the recommended temperature and the current outdoor ambient temperature is obtained by querying the preset database.

[0088] The preset database stores the corresponding relationship between the recommended temperature, the current outdoor ambient temperature and the switching mode.

[0089] For example, see Figure 5 , a certain range is set in the preset database (T 外1 , T 外2 ) within a certain range (T 目标1 、T 目标2 ) within the recommended temperature.

[0090] For example, see Figure, T 外1 At 10°C, T 外2 At 29°C, T 推荐1 16℃, T 目标2 At 30°C,

[0091] When the outdoor ambient temperature is within the range of [10℃, 12℃], the switching mode is heating mode regardless of the recommended temperature.

[0092] When the outdoor ambient temperature is within the range of [13°C, 14°C], if the temperature difference between the recommended temperature and the outdoor ambient temperature is greater than or equal to 4°C, the switching mode is heating mode.

[0093] When the outdoor ambient temperature is within the range of [15℃, 17℃], if the temperature difference between the recommended temperature and the outdoor ambient temperature is greater than or equal to 5℃, the switching mode is heating mode.

[0094] When the outdoor ambient temperature is within the range of [18℃, 20℃], if the temperature difference between the recommended temperature and the outdoor ambient temperature is greater than or equal to 6℃, the switching mode is heating mode.

[0095] When the outdoor ambient temperature is within the range of [21°C, 23°C], if the temperature difference between the recommended temperature and the outdoor ambient temperature is greater than or equal to 7°C, the switching mode is heating mode.

[0096] For heating mode, see Figure 5 The gray grid part in the upper left corner.

[0097] When the outdoor ambient temperature is within the range of [28℃, 29℃], the switching mode is cooling mode regardless of the recommended temperature.

[0098] When the outdoor ambient temperature is within the range of [26℃, 27℃], if the temperature difference between the outdoor ambient temperature and the recommended temperature is greater than or equal to 0℃, the switching mode is cooling mode.

[0099] When the outdoor ambient temperature is within the range of [24℃, 25℃], if the temperature difference between the outdoor ambient temperature and the recommended temperature is greater than or equal to 1℃, the switching mode is cooling mode.

[0100] When the outdoor ambient temperature is within the range of [22℃, 23℃], if the temperature difference between the outdoor ambient temperature and the recommended temperature is greater than or equal to 2℃, the switching mode is cooling mode.

[0101] When the outdoor ambient temperature is within the range of [20℃, 21℃], if the temperature difference between the outdoor ambient temperature and the recommended temperature is greater than or equal to 4℃, the switching mode is cooling mode.

[0102] For cooling mode, see Figure 5 The gray grid part in the lower right corner.

[0103] When the remaining outdoor ambient temperature corresponds to the remaining recommended temperature, the switching mode is the air supply mode.

[0104] For air supply mode, see Figure 5 The white grid part in the lower right corner.

[0105] In some embodiments of the present application, the switching modes in the preset database can also be freely set according to needs.

[0106] S4: Determine whether the operation mode and the switching mode of the air-conditioning device are consistent. If so, proceed to S5; if not, proceed to S6.

[0107] The operation mode indicates the current operation mode of the air conditioner, such as cooling mode, heating mode, and air supply mode.

[0108] S5: This mode and temperature control instruction controls the temperature of the air conditioning equipment with the recommended temperature as the indoor target temperature.

[0109] When the current operating mode and the switching mode are consistent, it means that there is no need to switch the mode at present.

[0110] However, since the current temperature of the air-conditioning equipment during operation is inconsistent with the recommended temperature, this mode and temperature control instruction uses the recommended temperature as the indoor target temperature to control the temperature of the air-conditioning equipment to meet the user's comfort level.

[0111] Therefore, the mode and temperature control instructions at this time only use the recommended temperature as the indoor target temperature to control the temperature of the air-conditioning equipment.

[0112] S6: The mode and temperature control instruction switches the air conditioning device to the switching mode, and controls the temperature of the air conditioning device with the recommended temperature as the indoor target temperature.

[0113] When the current operating mode and the switching mode are inconsistent, it indicates that a mode switching is required, wherein the mode switched to is the switching mode determined in S3.

[0114] Furthermore, since the current temperature of the air-conditioning device during operation is inconsistent with the recommended temperature, the current indoor target temperature also needs to be updated with the recommended temperature.

[0115] Therefore, the mode and temperature control instructions at this time not only control the mode switching of the air-conditioning device, but also control the temperature of the air-conditioning device with the recommended temperature as the indoor target temperature.

[0116] Humidity control instructions

[0117] See also Figure 6 , after the cloud platform 20 receives the recommended humidity, it performs the following operations.

[0118] S1': Determine whether the recommended humidity is consistent with the current humidity. If so, proceed to S2'; if not, proceed to S3'.

[0119] Recommended humidity is the recommended target indoor humidity.

[0120] The current humidity is the actual humidity in the room.

[0121] The recommended humidity here may be a humidity value or a humidity range.

[0122] When the current humidity is equal to the humidity value indicating the recommended humidity or the current humidity is within the humidity range indicating the recommended humidity, it can be considered that the recommended humidity and the current humidity are consistent; otherwise, it is considered that the recommended humidity and the current humidity are inconsistent.

[0123] S2': The humidity control command enables the air conditioning equipment to maintain the current humidity control.

[0124] When the recommended humidity is consistent with the current humidity, it means that the current humidity operating condition of the air-conditioning equipment meets the user's comfort requirements, and there is no need to adjust the humidity of the air-conditioning equipment.

[0125] Therefore, the humidity control instruction at this time makes the air conditioning equipment maintain the current humidity control.

[0126] S3': The humidity control instruction enables the air-conditioning device to control the humidity of the air-conditioning device with the recommended humidity as the indoor target humidity.

[0127] In some embodiments of the present application, if the air-conditioning device has a humidification function, when the recommended humidity is higher than the current humidity, the humidity control instruction at this time causes the air-conditioning device to perform humidification control on the air-conditioning device with the recommended humidity as the indoor target humidity.

[0128] When the recommended humidity is lower than the current humidity, the humidity control instruction at this time causes the air-conditioning device to perform dehumidification control on the air-conditioning device with the recommended humidity as the indoor target humidity.

[0129] Regardless of whether the air-conditioning device has a humidification function or not, when the recommended humidity is lower than the current humidity, the humidity control instruction at this time causes the air-conditioning device to perform dehumidification control on the air-conditioning device with the recommended humidity as the indoor target humidity, that is, enter the defrost mode.

[0130] In some embodiments of the present application, if dehumidification of the air-conditioning equipment is required, the mode, temperature control instructions and wind speed control instructions are not issued.

[0131] Wind speed control command

[0132] See also Figure 7 , after the cloud platform 20 receives the recommended wind speed, it performs the following operations.

[0133] S1'': Determine whether the recommended wind speed is consistent with the current wind speed. If so, proceed to S2''; if not, proceed to S3''.

[0134] The recommended wind speed is the recommended target indoor wind speed.

[0135] The current wind speed is the actual wind speed in the room.

[0136] The recommended wind speed here can be a wind speed value or a wind speed range.

[0137] When the current wind speed is equal to the wind speed value indicating the recommended wind speed or is within the wind speed range indicating the recommended wind speed, it can be considered that the recommended wind speed and the current wind speed are consistent; otherwise, it is considered that the recommended wind speed and the current wind speed are inconsistent.

[0138] S2'': The wind speed control command enables the air conditioning equipment to maintain the current wind speed control.

[0139] When the recommended wind speed is consistent with the current wind speed, it means that the current wind speed operation status of the air-conditioning equipment meets the user's comfort requirements, and there is no need to adjust the wind speed of the air-conditioning equipment.

[0140] Therefore, the wind speed control instruction at this time enables the air conditioning equipment to maintain the current wind speed control.

[0141] S3'': The wind speed control instruction enables the air conditioning equipment to control the air inlet speed of the air conditioning equipment with the recommended wind speed as the indoor target wind speed.

[0142] In some embodiments of the present application, in order to avoid the disturbance of indoor temperature and the influence of wind speed adjustment on user comfort, when adjusting the wind speed, the adjustable wind speed adjustment range of the air-conditioning equipment (such as the gear of the fan) is first obtained, and the wind speed is gradually adjusted with a certain adjustment step.

[0143] The certain adjustment step may be the minimum adjustment step of the wind speed, or N times (N>1) the minimum adjustment step.

[0144] When the current wind speed is lower than the recommended wind speed, gradually increase the wind speed with a certain adjustment step length.

[0145] When the current wind speed is greater than the recommended wind speed, the wind speed is gradually reduced with a certain adjustment step length.

[0146] During wind speed adjustment, a cycle (e.g. 1 minute) for increasing or decreasing the adjustment step can be set, that is, the wind speed is increased or decreased with a certain adjustment step every one minute, so as to adjust the wind speed while minimizing the impact of wind speed disturbance on user comfort.

[0147] In the air-conditioning control system as described above, the cloud platform integrates the adjustment instructions about temperature, humidity and wind speed to form control instructions, which are sent to the control panel, and then sent to the air-conditioning equipment to realize remote control of the air-conditioning equipment.

[0148] This control method takes into account both user comfort and remote intelligent control, making it easier for users to use and improving product selling points.

[0149] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
