Description

Technical Field

[0001] This application relates to the technical field of air conditioner control, and particularly to an air conditioner control method, device, air conditioner and storage medium. Background Art

[0002] With the progress of technology, users have put forward higher requirements for air conditioner variable frequency control technology. For example, the energy-saving technology of air conditioners is relatively mature in the cooling mode. However, in the heating mode, especially when heating at low temperatures, the heating capacity of the air conditioner heat pump will be affected, so it may not be able to meet the user's needs. Electric auxiliary heating can provide additional heat to maintain the indoor temperature at the set temperature. However, on the one hand, using electric auxiliary heating will increase additional energy consumption, resulting in energy inefficiency; on the other hand, turning on electric auxiliary heating will cause changes in indoor temperature stratification, exacerbating the temperature stratification, which may lead to inaccurate temperature control.

[0003] In an existing air conditioner control method, after the electric auxiliary heating is turned on, the electric auxiliary heating is turned off only when the compressor frequency is less than a certain preset frequency, and after turning off, the frequency is compensated according to a certain fixed value to maintain the indoor temperature stable at the set temperature. On the one hand, if the preset frequency is set unreasonably, in some working conditions, even if the heat output of the heat pump can maintain the indoor temperature at the set temperature, the electric auxiliary heating cannot be turned off, resulting in energy inefficiency. On the other hand, because the compensated frequency after turning off the electric auxiliary heating is fixed, when facing different working conditions, being too large or too small is likely to cause temperature fluctuations, resulting in discomfort for users.

[0058] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0059] In order to better understand the technical solutions of the present application, the following will be described in detail with reference to the accompanying drawings of the specification and specific embodiments.

[0060] The main solution of the embodiment of the present application is: obtaining the heating data of the air conditioner; determining whether the air conditioner meets the electric auxiliary heating shutdown condition according to the heating data; when the air conditioner meets the electric auxiliary heating shutdown condition, determining the compensation frequency according to the heating data; controlling the operation of the compressor according to the compensation frequency.

[0061] Since there may be situations in the prior art during specific implementation that may lead to high energy consumption and discomfort for users. On the one hand, if the preset frequency is set unreasonably, it may lead to the inability to turn off the electric auxiliary heating in some working conditions, even if the heat output of the heat pump can maintain the indoor temperature at the set temperature, resulting in energy inefficiency. On the other hand, because the compensation frequency after turning off the electric auxiliary heating is fixed, when facing different working conditions, being too large or too small is likely to cause temperature fluctuations, thus causing discomfort to users.

[0062] The present application provides a solution, aiming to estimate the output capacity and load of the air conditioner and accordingly determine the electric auxiliary heating shutdown condition and the frequency compensation value after shutdown, so as to improve the energy efficiency and comfort of the air conditioner.

[0063] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, the controller inside the air conditioner, etc. Hereinafter, the controller inside the air conditioner will be taken as an example to describe this embodiment and the following embodiments.

[0064] Based on this, an embodiment of the present application provides an air conditioner control method. Referring to Figure 1 , Figure 1 which is a schematic flowchart of the first embodiment of the air conditioner control method of the present application.

[0065] In this embodiment, the air conditioner control method includes steps S10 to S40:

[0066] Step S10: Obtain the heating data of the air conditioner.

[0067] It should be noted that the heating data of the air conditioner refers to the energy data generated when the air conditioner is in the heating energy-saving mode and the electric auxiliary heating is turned on. It may include the cooling load, total heating capacity, and electric auxiliary heating capacity of the air conditioner. Among them, the cooling load refers to the external environmental load that the air conditioner needs to overcome during the heating process, the total heating capacity is the total amount of heat generated by the air conditioner during the heating process, and the electric auxiliary heating capacity is the heat generated by the auxiliary heating element during the heating process of the air conditioner.

[0068] Step S20: Determine whether the air conditioner meets the electric auxiliary heating shutdown condition according to the heating data.

[0069] It should be noted that after obtaining the heating data of the air conditioner, a heating capacity threshold can be determined. By comparing the cooling load in the heating data with this heating capacity threshold, it can be judged when to turn off the electric auxiliary heating so that the heat pump can maintain the indoor temperature stable at the set temperature.

[0070] In a feasible implementation manner, step S20 may include steps A10 to A12:

[0071] Step A10: Obtain the theoretical heating capacity threshold of the heat pump under different working conditions.

[0072] It should be noted that a heat pump is a device that uses a compressor. In the heating mode, the theoretical heating capacity threshold of the heat pump refers to the maximum heating capacity that the heat pump can provide under different working conditions to ensure that the indoor temperature can reach or exceed the set temperature.

[0073] It can be understood that the theoretical heating capacity threshold of the heat pump under different working conditions is calibrated through various experiments in the working condition chamber. Usually, the theoretical maximum heating capacities of 1 to n under several working conditions are measured.

[0074] In a specific implementation, obtain the maximum frequency upper limit f of the compressor considering various protections max , the current air volume Vol, the outdoor temperature, the exhaust temperature, and the indoor temperature T 1, perform experimental calibration based on the above data, and then the theoretical maximum heating capacity of the heat pump alone under several working conditions can be calculated when the electric auxiliary heating is turned off in the current environment.

[0075] Step A11, determine the target heating capacity threshold of the heat pump according to the theoretical heating capacity threshold.

[0076] It should be noted that according to the obtained theoretical heating capacity thresholds of the heat pump under different working conditions, the target heating capacity threshold Q can be obtained by approximate calculation using the method of linear interpolation or mechanism model. p_max 。

[0077] Step A12, determine whether the electric auxiliary heating off condition is satisfied according to the target heating capacity threshold and the cooling load in the heating data.

[0078] It should be noted that the cooling load Q load is the external environmental load that the air conditioner needs to overcome during the heating process. At the target heating capacity threshold, the target heating capacity threshold Q p_max can be regarded as the maximum heating capacity that the heat pump can provide in the current environment.

[0079] It can be understood that by determining whether the difference between the current indoor temperature and the set temperature is within the preset range, if it is within the preset range, then by comparing the cooling load Q load with the target heating capacity threshold Q p_max it can be judged whether the condition for turning off the electric auxiliary heating is satisfied. If the target heating capacity threshold is greater than the cooling load, that is, Q p_max >Q load , it means that the heat pump can independently maintain the indoor temperature within the set temperature range, and at this time, the electric auxiliary heating can be turned off, that is, the electric auxiliary heating off condition is satisfied; otherwise, the electric auxiliary heating needs to be continued to ensure the stability of the indoor temperature, that is, the electric auxiliary heating off condition is not satisfied.

[0080] Step S30: When the air conditioner satisfies the electric auxiliary heating off condition, determine the compensation frequency according to the heating data.

[0081] It can be understood that when it is determined that the air conditioner satisfies the electric auxiliary heating off condition, turn off the electric auxiliary heating and enter the electric auxiliary heating off compensation stage, and further determine the compensation frequency of the compressor operation according to the heating data.

[0082] It should be noted that the compensation frequency refers to the frequency that the compressor needs to increase its operation after the electric auxiliary heating of the air conditioner is turned off to compensate for the reduced heating capacity after the electric auxiliary heating is turned off in order to maintain the stability of the indoor temperature.

[0083] Step S40: Control the operation of the compressor according to the compensation frequency.

[0084] It should be noted that after determining the compensation frequency Δf, obtain the operating frequency f before turning off the electric auxiliary heating. r , according to the compensation frequency Δf and the operating frequency f before turning off the electric auxiliary heating r , the compensated operating frequency can be obtained. The compensated operating frequency = Δf + the operating frequency f before turning off the electric auxiliary heating r , within a preset future time, the compressor operates at the compensated operating frequency. After the preset time ends, exit the compensation stage and control the compressor frequency according to the normal frequency control logic.

[0085] This embodiment provides an air conditioner control method, which obtains the heating data of the air conditioner; determines whether the air conditioner meets the electric auxiliary heating shutdown condition according to the heating data; when the air conditioner meets the electric auxiliary heating shutdown condition, determines the compensation frequency according to the heating data; and controls the operation of the compressor according to the compensation frequency. By determining whether the air conditioner meets the electric auxiliary heating shutdown condition according to the heating data of the air conditioner, the frequency compensation value of the compressor is determined when the electric auxiliary heating is turned off, and the operation of the compressor is controlled accordingly, which can adapt to the dynamically changing working conditions while further improving the energy saving rate and comfort of the existing variable-frequency air conditioner.

[0086] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar content as in the above-mentioned first embodiment can be referred to the above introduction and will not be repeated hereinafter. On this basis, please refer to Figure 2 , step S30 includes steps S301 to S302:

[0087] Step S301: When the electric auxiliary heating shutdown condition is met, turn off the electric auxiliary heating of the air conditioner.

[0088] It can be understood that turning off the electric auxiliary heating can be achieved by controlling the relay or contactor in the circuit to ensure that the electric auxiliary heating element no longer consumes electric energy, thereby reducing the energy consumption of the entire air-conditioning system. After turning off the electric auxiliary heating, the air conditioner will mainly rely on the heating capacity of the heat pump to maintain the indoor temperature.

[0089] Step S302: When the electric auxiliary heating is turned off, determine the compensation frequency according to the cooling load and the electric auxiliary heating heat output in the heating data.

[0090] It should be noted that after turning off the electric auxiliary heating, the heat pump needs to independently provide sufficient heat output to maintain the indoor temperature. According to the electric auxiliary heating heat output that can be provided before turning off the electric auxiliary heating and the cooling load, the compensation frequency of the compressor operation can be determined. The larger the compensation frequency, the more heat output the heat pump needs to provide to make up for the reduced heat output after turning off the electric auxiliary heating.

[0091] It is understandable that when the electric auxiliary heating is turned off, the frequency increment for a future period is determined according to the electric auxiliary heating power, and then the operating frequency of the compressor is supplemented, so as to ensure that the temperature will not drop rapidly after the electric auxiliary heating is turned off and improve the user comfort.

[0092] In a feasible implementation manner, step S302 may include steps B10 to B12:

[0093] Step B10, determining the compensated heating capacity according to the cooling load and the electric auxiliary heating capacity in the heating data.

[0094] It should be noted that the compensated heating capacity is the heating output capacity Q that needs to be compensated to maintain the current heating capacity not less than the cooling load after the electric auxiliary heating is turned off, c , as follows:

[0095] Q c =(Q load -Q PTC )

[0096] Wherein, Q c is the heating output capacity that needs to be compensated, that is, the compensated heating capacity, Q load is the cooling load, Q PTC is the electric auxiliary heating capacity.

[0097] Step B11, obtaining the operating frequency data of the compressor and the target heating capacity threshold of the heat pump.

[0098] It should be noted that the operating frequency data of the compressor includes the operating frequency f r before turning off the electric auxiliary heating and the maximum frequency upper limit f max of the compressor considering various protections. The target heating capacity threshold Q p_max of the heat pump can also be obtained.

[0099] Step B12, determining the compensation frequency according to the operating frequency data, the compensated heating capacity and the target heating capacity threshold.

[0100] It should be noted that according to the operating frequency f r before turning off the electric auxiliary heating, the maximum frequency upper limit f max of the compressor considering various protections, the heating output capacity Q c that needs to be compensated, and the target heating capacity threshold Q p_max of the heat pump, the additional compensation frequency Δf required for the compressor during operation is calculated as follows:

[0101]

[0102] Wherein, Δf is the compensation frequency, Q out is the heating capacity before turning off the electric auxiliary heating at f rThe total heating capacity of the air conditioner during operation can be calculated by the energy consumption prediction method. The core idea of this formula is as follows: By means of linear interpolation, according to the ratio relationship between the additional output capacity that can be increased at the maximum operating frequency and the current heating capacity to be compensated, the frequency to be compensated is determined. Specifically, the heat to be compensated is Q c The larger it is, the larger the compensation frequency Δf is.

[0103] In this embodiment, when the electric auxiliary heating is turned off under the condition that the electric auxiliary heating is turned off, the electric auxiliary heating of the air conditioner is turned off, and the compensation frequency is more accurately determined according to the cooling load and the electric auxiliary heating capacity, so as to ensure the stability of the temperature after the electric auxiliary heating is turned off and improve the comfort of the user.

[0104] Based on the first embodiment of the present application, in the third embodiment of the present application, the same or similar content as that in the above-mentioned first embodiment can be referred to the above introduction and will not be described in detail hereinafter. On this basis, please refer to Figure 3 , step S10 includes steps S101 to S103:

[0105] Step S101: When the electric auxiliary heating is turned on, obtain the operation data and environmental temperature data of the air conditioner.

[0106] It should be noted that both the operation data and environmental temperature data of the air conditioner can be obtained through the sensor data during the operation of the air conditioner. The operation data may include the air volume data and exhaust temperature data of the air conditioner, and the environmental temperature data may include indoor temperature data, outdoor temperature data, evaporator temperature data, etc. This embodiment does not make specific limitations on this.

[0107] Step S102: Perform energy consumption prediction according to the operation data and the environmental temperature data to obtain the cooling load, total heating capacity and electric auxiliary heating capacity of the air conditioner.

[0108] It can be understood that after the heating energy-saving mode is turned on, if the electric auxiliary heating is turned on, it is in the energy consumption prediction stage, and it is necessary to perform energy consumption prediction on the air conditioner according to the operation data and environmental temperature data, and predict the cooling load, total heating capacity and electric auxiliary heating capacity of the air conditioner under the current conditions.

[0109] In a feasible implementation manner, step S102 may include steps C10 to C13:

[0110] Step C10, determine the air volume data according to the operation data, and determine the evaporator temperature data and indoor temperature data according to the environmental temperature data.

[0111] It should be noted that the operation data may include the air volume data and the exhaust temperature data of the air conditioner. The air volume data of the air conditioner may include the current air volume data and the historical air volume data. The exhaust temperature data may include the current exhaust temperature data and the historical exhaust temperature data. The ambient temperature data may include the indoor temperature data and the evaporator temperature data. Both the indoor temperature data and the evaporator temperature data may include the historical temperature data or the current temperature data.

[0112] It can be understood that the data such as the air volume data, the evaporator temperature data, and the indoor temperature data determined according to the operation data and the ambient temperature data can accurately predict the heating data such as the cooling load, the total heating capacity, and the electric auxiliary heating capacity of the air conditioner under the current conditions.

[0113] Step C11, predicting the total heating capacity and the electric auxiliary heating capacity of the air conditioner according to the evaporator temperature data, the air volume data, and the indoor temperature data.

[0114] It should be noted that according to the evaporator temperature data, the air volume data, and the indoor temperature data, the heating output capacity Q of the electric auxiliary heating of the air conditioner can be estimated PTC , that is, the electric auxiliary heating capacity. The electric auxiliary heating capacity is a part of the total heating capacity of the air conditioner. Based on the evaporator temperature data, the air volume data, and the indoor temperature data, combined with the exhaust temperature, the current heating output capacity Q of the air conditioner can be calculated out , that is, the total heating capacity.

[0115] Step C12, determining the change in indoor temperature according to the indoor temperature data.

[0116] It should be noted that according to the historical temperature data in the indoor temperature data, the change in indoor temperature ΔT within a preset time can be determined 1 , and based on ΔT 1 , the cooling load during the operation of the air conditioner can be estimated.

[0117] Step C13, predicting the cooling load of the air conditioner according to the total heating capacity and the change in indoor temperature.

[0118] It should be noted that after determining the change in indoor temperature, the cooling load of the air conditioner can be further predicted in combination with the total heating capacity of the air conditioner, as shown in the following formula:

[0119] Q load =Q out -ΔT 1 *C*p*V room

[0120] where Q load represents the indoor cooling load, V room represents the equivalent room size, and ΔT 1It represents the change in indoor temperature per unit time. From the perspective of energy conservation, this calculation formula represents that the heating output heat is equal to the work done to raise the indoor temperature and the heat consumed to offset the room cooling load.

[0121] In a feasible implementation manner, the steps of predicting the total heating capacity and the electric auxiliary heating capacity of the air conditioner according to the evaporator temperature data, the air volume data, and the indoor temperature data may include: determining the exhaust gas temperature data according to the operation data; predicting the total heating capacity of the air conditioner according to the evaporator temperature data, the air volume data, the indoor temperature data, and the exhaust gas temperature data; predicting the electric auxiliary heating power according to the evaporator temperature data, the air volume data, and the indoor temperature data; and determining the electric auxiliary heating capacity of the air conditioner according to the electric auxiliary heating power.

[0122] It should be noted that the data such as the evaporator temperature data, the air volume data, the indoor temperature data, and the exhaust gas temperature data used when predicting the total heating capacity of the air conditioner are all current data. According to the current evaporator temperature, the current air volume, the current indoor temperature, and the current exhaust gas temperature, the current heating output capacity Q can be estimated out , as shown in the following formula:

[0123] Q out =(α 1 *(T 2 -T 1 )+α 2 *(T 1 -T p ))*Vol

[0124] wherein, T 1 , T 2 , T p are the current indoor temperature, the current evaporator temperature, and the current exhaust gas temperature, α 1 , α 2 are two parameters that need to be identified through experiments, and Vol is the current air volume of the air conditioner. Specifically, the evaporator temperature is in a direct proportional relationship with the outlet air temperature. The higher the evaporator temperature T 2 , the higher the outlet air temperature. When the air volume of the fan is constant, the greater the temperature difference between the outlet air temperature and the indoor temperature, the greater the heating capacity, and vice versa. Therefore, through the above operation data and environmental temperature data, the heating capacity of the air conditioner can be estimated.

[0125] It can be understood that the evaporator temperature data, the air volume data, and the indoor temperature data used to determine the electric auxiliary heating capacity of the air conditioner are also all current data. According to the current evaporator temperature, the current air volume, and the current indoor temperature, the power W of the electric auxiliary heating is estimated i, the corresponding relationship between the power, air volume, and evaporator temperature can be determined through laboratory tests. The electric auxiliary heating power is proportional to the air volume and inversely proportional to the evaporator temperature. The larger the air volume, the greater the electric auxiliary heating power; the higher the evaporator temperature, the smaller the electric auxiliary heating power.

[0126] It should be noted that the output power of the electric auxiliary heating is approximately equal to the heating output of the electric auxiliary heating. Therefore, the heating output capacity Q of the electric auxiliary heating PTC can be approximately estimated by the following formula:

[0127] Q PTC = α 1 *W i + b

[0128] where α 1 is the heating capacity attenuation coefficient, b is the heating capacity attenuation gain. Considering various losses in energy conversion, it is calibrated through experiments. W i is the power of the electric auxiliary heating.

[0129] Step S403: Determine the heating data of the air conditioner according to the cooling load, the total heating capacity, and the electric auxiliary heating capacity.

[0130] It should be noted that the cooling load, total heating capacity, and electric auxiliary heating capacity of the air conditioner are used as the heating data of the air conditioner, and based on this, the electric auxiliary heating shutdown condition and the frequency compensation value after shutdown are determined, thereby improving the energy efficiency and comfort of the air conditioner.

[0131] In this embodiment, energy consumption prediction is performed through the operation data and ambient temperature data of the air conditioner, and the heating data such as the cooling load, total heating capacity, and electric auxiliary heating capacity of the air conditioner are quickly determined. Based on this, the electric auxiliary heating shutdown condition and the frequency compensation value after shutdown are accurately determined, thereby improving the energy efficiency and comfort of the air conditioner.

[0132] Exemplarily, to help understand the implementation process of the air conditioner control method obtained by combining this embodiment with the above Embodiment 1, please refer to Figure 4 , Figure 4 A brief flow schematic diagram of an air conditioner control method is provided. Specifically: S1: After the user turns on the heating energy-saving mode, if the electric auxiliary heating is turned on, it is first in the energy consumption prediction stage 1. First, according to the historical operation data (indoor and outdoor temperatures, air volume, etc.), the cooling load and heating output capacity of the air conditioner are predicted according to the energy consumption prediction method 1. S2: Every preset time, according to the current air volume, and the evaporator and indoor temperatures, the electric auxiliary heating power and output capacity are predicted, and through the electric auxiliary heating control logic 2, the electric auxiliary heating shutdown condition is judged. S3: If the electric auxiliary heating shutdown condition is met, enter the compensation stage 2. According to the electric auxiliary heating output capacity before compensation, the compensation is calculated according to the feedforward compensation calculation logic 3, and the compressor operation is controlled.

[0133] Exemplarily, to facilitate understanding of the implementation process of the air conditioner control method obtained by combining the present embodiment with the above-mentioned first embodiment, please refer to Figure 5 , Figure 5 A detailed flowchart of an air conditioner control method is provided. Specifically: after the heating energy-saving mode is turned on, it is determined whether the electric auxiliary heating is in the on state; if the electric auxiliary heating is not on, it is in the normal operation stage and operates normally according to the conventional algorithm; if the electric auxiliary heating is on, it enters the energy consumption prediction stage. Every preset time 1, the air conditioner operation data is acquired, and according to the current air volume, evaporator temperature, and room temperature change, the heating output capacity Qout and the cooling load Qload are estimated. It is determined whether the theoretical maximum heating capacity Qp_max of the heat pump is greater than the heat load Qload.
