Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning control method, device, medium, electronic equipment and a kitchen air conditioning system. Background Art

[0002] With the continuous improvement of people's living standards and living conditions, the demand for kitchen air conditioners is becoming increasingly strong. However, due to the high temperature, high humidity and heavy smoke in the kitchen, the return air filter of the kitchen air conditioner is prone to dirty and blocked during use, which leads to reduced air volume and poor cooling effect.

[0003] At present, there are some studies on the problem of oil smoke, mainly from the aspects of filter material improvement, electrostatic pre-filtration, nanomaterial application, radiator surface modification, oil-water separator, etc. In the application of kitchen air conditioners, there is no good solution to the problem of oil pollution. A certain brand of central kitchen air conditioner adds a layer of filter cotton at the return air inlet and changes the fin structure to allow the oil pollution to slide away. However, the oil pollution will also remain on the surface of components inside the casing such as volute, impeller, guide plate, filter, etc., or on the surface of the casing. The oil pollution forms an oil film on the surface of these components and is evenly attached to these components. If it is not cleaned for a long time, the oil pollution will become sticky and gradually solidify.

[0004] At present, there is a lack of detection methods specifically for the dirtiness and blockage of the kitchen air conditioner return air filter. Using only a single parameter for judgment will increase the error and have defects such as untimely, unintelligent and inaccurate reminders, resulting in no reminders or false reminders. Users cannot understand the blockage status of the filter in real time, and cannot adjust the air intake volume according to the indoor oil fume situation and the dirtiness and blockage status of the return air filter. It is impossible to avoid the deterioration of cooling and heating effects due to the dirtiness and blockage of the return air filter, and it affects the indoor air quality. Summary of the invention

[0005] The purpose of the present invention is to provide an air conditioning control method, device, medium, electronic equipment and kitchen air conditioning system to solve the technical problems in the prior art that the existing kitchen air conditioning return air vent does not fully consider the oil fume filtration, cannot accurately feedback the filter clogging situation, and cannot promptly remind the user to clean the filter, resulting in excessive oil deposition and difficulty in cleaning.

[0025] When the oil fume concentration is ≥ the second set concentration a2, the fan in the air conditioner is controlled to run at a low speed, and the user is reminded to turn on the range hood extraction or adjust the range hood wind speed.

[0054] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0055] The present invention provides an air conditioning control method, which is used to detect oil blockage in a kitchen air conditioning filter. The method determines the oil blockage of the filter by pressure difference and capacity attenuation, and promptly reminds the user to clean it, which can avoid excessive oil deposition to a great extent and further ensure the performance of the air conditioner.

[0056] Specifically, Figure 1 As shown, the air conditioning control method of the present invention includes:

[0057] Step S1, calculating a reference value for determination; wherein the reference value for determination includes a reference pressure difference and a reference output capacity; specifically, including:

[0058] Step S11: Figure 2 As shown, after the air conditioner is installed in the kitchen, the setting mode is started and operated. When the kitchen air conditioner is turned on during the non-cooking period and it is the first time to be turned on or after cleaning, the air conditioner detects indoor and outdoor environmental parameters, pressure difference before and after the filter, oil smoke concentration, and gas concentration to obtain background data;

[0059] Step S12, based on the detected indoor and outdoor environmental parameters, the operating parameters of each actuator (compressor, electronic expansion valve, internal and external fan power, etc.), the artificial neural network built into the air-conditioning control system is input to calculate the air-conditioning benchmark output capacity; it should be noted here that the air-conditioning benchmark output capacity is not only marked at the first start-up, but also preset capacity benchmark values ​​for each temperature and humidity range, set temperature, and operating windshield in the design stage in order to adapt to different regions and user settings. If the user setting during operation does not match the marked setting during the first operation, the factory preset capacity benchmark value is called for calculation;

[0060] Step S13, record and mark the detected pressure difference before and after the filter and the calculated reference output capacity as the reference value for subsequent operation for comparison and judgment.

[0061] Step S2, obtaining environmental parameters, wherein the environmental parameters include gas concentration and oil fume concentration; specifically, when the air conditioner is not turned on for the first time, the air conditioner receives a power-on instruction to start the power-on, and first obtains conventional environmental parameters, such as temperature and humidity, gas concentration, and oil fume concentration;

[0062] Step S3, based on the acquired environmental parameters, controlling the fan speed; wherein the environmental parameters include gas concentration, oil fume concentration, and temperature and humidity; the control method of the present invention can automatically detect the oil fume concentration in the kitchen indoor environment, sense the oil fume concentration, and adjust the operation of the kitchen air conditioner according to the oil fume concentration;

[0063] Specifically, they include:

[0064] Step S31: Figure 2 As shown, when the obtained gas concentration exceeds the standard, the air conditioner light is controlled to flash to remind the user;

[0065] Step S32: When the obtained gas concentration is within a safe range, the air conditioner is started;

[0066] Step S33: After the air conditioner is started, the current indoor fume concentration is detected;

[0067] Step S34: Based on the detected oil smoke concentration, the operating speed of the fan in the air conditioner is controlled. Specifically:

[0068] like Figure 3 As shown, when the oil smoke concentration is less than the first set concentration a1, the fan in the air conditioner is controlled to run at a high speed;

[0069] When the first set concentration a1≤the fume concentration<the second set concentration a2, the fan in the air conditioner is controlled to run at a medium speed;

[0070] When the oil fume concentration is ≥ the second set concentration a2, the fan in the air conditioner is controlled to run at a low speed, and the user is reminded to turn on the range hood extraction or adjust the range hood wind speed.

[0071] The air intake of the air conditioner is related to the fan speed. When the oil fume concentration is high, if a higher fan speed is used, more oil fume molecules suspended in the air will be drawn to the air inlet of the air conditioner, accelerating the deposition of oil fume on the air conditioner filter. Therefore, in this method, the fan runs at high speed when the oil fume concentration is low, and runs at low speed when the oil fume concentration is high, so as to ensure stable output of cooling capacity and slow down the oil fume deposition rate.

[0072] It should be noted here that the first set concentration a1 and the second set concentration a2 may range from 0 to 300 mg.

[0073] Step S4, obtaining the air inlet pressure difference before and after the filter and the real-time output capacity; specifically,

[0074] The air inlet pressure before and after the filter is obtained, and then the air inlet pressure difference is calculated by the air inlet pressure on both sides; in this embodiment, the calculation process of the air inlet pressure difference is to obtain the pressure value by using the periodic average method during the operation of the air conditioner, for example, the pressure value is collected once every t1 (value range 0~2s), and then the value after continuous collection of n (value range 0~200) times within t2 (value range 0~50s) is averaged to obtain the output value, that is, the pressure value P=(P1+P2+P3+…+Pn) / n. Air inlet pressure difference = internal pressure-external pressure; Note: The pressure here can be total pressure, dynamic pressure, static pressure, without restriction.

[0075] Then calculate the real-time output capability;

[0076] Step S5, comparing the obtained air inlet pressure difference with the reference pressure difference in the judgment reference value, and comparing the obtained real-time output capacity with the reference output capacity in the judgment reference value. When both the pressure difference and the output capacity meet the requirements, performing filter clearing processing;

[0077] Specifically, they include:

[0078] like Figure 4 As shown, when the air inlet pressure difference is greater than the reference pressure difference, and the difference between the air inlet pressure difference and the reference pressure difference is greater than the set differential pressure threshold y, it is judged that the first condition is met; that is, the calculated air inlet pressure difference is compared with the reference pressure difference value collected and marked when the air conditioner is first turned on. When the real-time air inlet pressure difference at the air inlet is greater than the reference pressure difference initially marked, and the difference between the two is greater than the set pressure difference threshold y, it indicates that one condition for blockage judgment is met; in this embodiment, the set pressure difference threshold y can take a value range of 0-500Pa.

[0079] Based on the real-time output capacity and the benchmark output capacity, the capacity attenuation value is calculated;

[0080] When the calculated capacity decay value is greater than the preset decay threshold x, it is determined that the second condition is met;

[0081] In this embodiment, the preset attenuation threshold value x can range from 0 to 20%. It should be noted here that the air conditioning capacity attenuation rate is calculated by calculating the real-time output capacity of the air conditioner and the marked initial benchmark output capacity or the preset capacity benchmark value, and is calculated using the following formula: Air conditioner capacity attenuation rate = [(Q1-Q2) / Q1]*100%; wherein: Q1 is the air conditioner benchmark output capacity, and Q2 is the air conditioner real-time output capacity.

[0082] In addition, the capacity decay value is calculated in real time, but the built-in program gives a preset decay threshold value x for comparison with the real-time capacity decay value; when the air conditioner is turned on for the first time, the output capacity of the air conditioner without oil pollution is marked for subsequent comparison, but the capacity will vary under different ambient temperature and humidity, user settings, etc. Therefore, during use, if the user settings, environmental parameters, etc. are different from the first time the air conditioner is turned on, the program will call the preset capacity values ​​for different environments and usage conditions as a comparison to determine the capacity decay situation.

[0083] When both the first condition and the second condition are met, it is determined that the filter is clogged by oil or other substances;

[0084] Then start the timing module to count the timing cycle;

[0085] When both conditions are met continuously within the set period T1, the user is reminded to clean the air inlet filter and perform filter unblocking processing.

[0086] It should be noted here that the value range of the setting period T1 can be 0-8 days.

[0087] Furthermore, users are reminded to clean the air inlet filter, including:

[0088] The first reminder is a voice broadcast reminder, and the fault code is displayed on the display screen;

[0089] Then, each time the machine is turned on, it will sound a beep several times to remind you, and the fault code will be displayed on the display screen; specifically, the several times can be three times, that is, each time the machine is turned on, it will sound a beep three times to remind you;

[0090] After the continuous reminder operation cycle T2 time, the air conditioner is not allowed to start. After cleaning is completed, the pressure difference and output capacity meet the requirements and can be started again.

[0091] It should be noted here that the operating cycle T2 can range from 0 to 100 days.

[0092] The air conditioning control method of the present invention also has a self-learning function, specifically:

[0093] The user's usage habits are recorded each time the air conditioner is turned on, such as: start-up time period, set temperature and mode, etc. After a certain period of record learning (taking 1 month as an example), the air conditioner can start the dehumidification mode in advance during the corresponding time period based on the recorded startup habits. If no fluctuations in oil smoke concentration and temperature and humidity in the room are detected within t3 (value range 0~50min), it will automatically shut down, otherwise it will operate normally.

[0094] After learning the user's usage habits, the air conditioner can automatically start the dehumidification mode at the same time period according to the user's startup habits. Then, in order to avoid the user not being in the kitchen to cook during this time period, causing the air conditioner to run for a long time when it is not needed, an automatic start-up shutdown judgment is added. When these two conditions are met, the air conditioner is turned off;

[0095] Specifically, the following conditions must be met for automatic shutdown:

[0096] (1) The oil smoke concentration is less than the first set concentration a1-▲a;

[0097] (2) The rate of change of indoor relative humidity (DH) is less than b (range 0-20) for a continuous period of t4 (range 0-50 min);

[0098] Where: DH = (Hi-H0) / H0;

[0099] H0 is the relative humidity when the machine is turned on;

[0100] Hi is the real-time relative humidity during operation;

[0101] ▲a value range 0~50;

[0102] The control method of the present invention collects the pressure of the kitchen air conditioner inlet by adding a pressure sensor, compares the difference between the pressure and capacity attenuation and the marked reference value in real time, determines the clogging condition of the air conditioner filter, and promptly reminds the user to clean the filter multiple times.

[0103] The air-conditioning control method provided by the present invention adds a gas-sensitive sensor to the air inlet of the air-conditioning to detect the kitchen fume concentration and gas concentration in real time, and then control the operating speed of the air-conditioning fan; at the same time, pressure sensors are installed on both sides of the air inlet filter to detect and calculate the pressure difference between the inside and outside of the filter, and at the same time calculate the degree of air-conditioning capacity attenuation to judge the blockage of the filter; the two sensors are combined to realize automatic detection of the oil fume concentration in the kitchen, adjust the operation of the kitchen air-conditioning, judge the blockage of the air-conditioning filter in real time, remind the user to clean the filter, avoid the problem of excessive oil pollution that is difficult to clean and affects the performance of the air-conditioning, judge the blockage of the filter by pressure difference and capacity attenuation, and remind the user to clean it in time, which can avoid excessive oil pollution deposition to a large extent, further ensure the performance of the air-conditioning, slow down the oil pollution deposition rate of the filter, solve the problem that the existing kitchen air-conditioning return air outlet does not fully consider the oil fume filtration and cannot accurately feedback the blockage of the filter, and can remind the user to clean the filter in time to avoid excessive oil pollution deposition that is difficult to clean.
