Description

Technical Field

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

[0002] In the related art, with the improvement of living standards, users have higher and higher demands for the comfort of air conditioning equipment such as air conditioners and dehumidifiers. When the air conditioner is heating, the problem of uneven heating outlet temperature often occurs. Under different heating conditions, the compressor frequency and the opening of the electronic expansion valve are different, which will cause the pressure corresponding to each flow path of the indoor heat exchanger to be different, and then the refrigerant flow of different flow paths is different, causing the difference in the temperature of the U tubes of different flow paths. In addition, the refrigerant temperature of the U tube at the inlet end, the U tube at the outlet end and the U tube in the middle of each flow path is different. Generally, the temperature of the U tube at the inlet section is greater than the temperature of the U tube in the middle and greater than the temperature of the U tube at the outlet during heating. This is caused by the continuous heat exchange of the refrigerant during the operation of the flow path. The above reasons show that when the air conditioner is heating, different U tubes will produce obvious temperature differences due to their positions in the flow path and the influence of different working conditions, which will cause the heating outlet temperature of the air conditioner to be uneven, affecting the comfort of the air conditioner.

[0003] In the related art, in order to avoid the phenomenon of cold air blowing caused by uneven heating air outlet temperature, the electric auxiliary heater is often turned on to increase the air outlet temperature of the air conditioner. However, the commonly used electric auxiliary heater can only increase the overall air outlet temperature, which not only cannot effectively solve the uneven heating air outlet temperature, but also causes the air outlet temperature to be too high and consumes power.

[0004] With respect to the above-mentioned problems existing in the related technologies, no efficient and accurate solutions have been found yet. Summary of the invention

[0037] In this embodiment, a heating control method of an air conditioner is provided. Figure 2 is a flow chart of a heating control method of an air conditioner according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0038] Step S202, when the air conditioner is in electric auxiliary heating mode, obtaining a plurality of heat exchange temperatures of the air conditioner, wherein the indoor heat exchanger of the air conditioner includes a plurality of heat exchange tubes, and each heat exchange tube corresponds to a heat exchange temperature;

[0039] Optionally, the electric auxiliary heating mode of the air conditioner can be manually turned on based on a user's control command, or it can be automatically turned on when the air conditioner meets the auxiliary heating start-up conditions.

[0040] Optionally, the air conditioner includes a heating method using an internal heat exchanger of a compressor and a heating method using an electric auxiliary heater.

[0041] Step S204, calculating the average heat exchange temperature of the heat exchanger according to the multiple heat exchange temperatures;

[0042] By calculating the average of multiple heat exchange temperatures, the average heat exchange temperature of the heat exchanger can be obtained.

[0043] Step S206, controlling the electric auxiliary heating state of the corresponding position of the air conditioner based on each heat exchange temperature and the average heat exchange temperature;

[0044] Among them, the heat exchange tube of each heat exchange temperature corresponds to an electric auxiliary heating state, and the electric auxiliary heating state at least includes turning on the electric auxiliary heating group at the corresponding position and turning off the electric auxiliary heating group at the corresponding position.

[0045] Through the above steps, when the air conditioner is turned on in the electric auxiliary heating mode, multiple heat exchange temperatures of the air conditioner are obtained, wherein the indoor heat exchanger of the air conditioner includes multiple heat exchange tubes, and each heat exchange tube corresponds to a heat exchange temperature; the average heat exchange temperature of the heat exchanger is calculated according to the multiple heat exchange temperatures; the electric auxiliary heating state of the corresponding position of the air conditioner is controlled based on each heat exchange temperature and the average heat exchange temperature, and the electric auxiliary heating state of the corresponding position of the air conditioner is controlled by adopting the average heat exchange temperature of the multiple heat exchange tubes of the air conditioner and the heat exchange temperature of each heat exchange tube. The electric auxiliary heating of the corresponding position can be started or shut down based on the temperature state of each heat exchange tube, which solves the technical problem of uneven air outlet temperature of air conditioning heating in the related technology and improves the user comfort of air conditioning heating.

[0046] In this embodiment, controlling the electric auxiliary heating state of the corresponding position of the air conditioner based on each heat exchange temperature and the average heat exchange temperature includes: calculating, for each target heat exchange tube of the indoor heat exchanger, a first temperature difference between the heat exchange temperature of the target heat exchange tube and the average heat exchange temperature; determining a target electric auxiliary heating group corresponding to the target heat exchange tube in the electric auxiliary heat of the air conditioner, wherein the electric auxiliary heat includes a plurality of electric auxiliary heating groups, and each heat exchange tube corresponds to at least one electric auxiliary heating group; and controlling the target electric auxiliary heating group according to the first temperature difference.

[0047] The target heat exchange tube is any heat exchange tube in the indoor heat exchanger.

[0048] Wherein, the first temperature difference=heat exchange temperature of the target heat exchange tube-average heat exchange temperature.

[0049] Figure 3 It is a schematic diagram of an electric auxiliary heater and an indoor heat exchanger in an embodiment of the present invention. The indoor heat exchanger includes a plurality of heat exchange tubes. The heat exchange tubes are generally designed to be U-shaped for convenient heat dissipation. The heat exchange tubes are also called U-tubes or heat exchanger tubes. Each U-tube has a temperature detector, which is fixed in the middle of the U-tube (it can also be fixed on both sides of the U-tube). The electric auxiliary heater includes a plurality of electric auxiliary heating groups (electric auxiliary heating units). Each U-tube can correspond to an electric auxiliary heating group of the electric auxiliary heater. The corresponding electric auxiliary heaters and the electric auxiliary heating groups have the same air outlet position. Each row of the electric auxiliary heater has a plurality of electric auxiliary heating plates with fixed and identical power or electric auxiliary heating plates with adjustable power.

[0050] The indoor heat exchanger of the air conditioner in this embodiment includes a plurality of flow paths, each flow path includes at least one heat exchange tube (U tube), each U tube corresponds to at least one electric auxiliary heating group of the electric auxiliary heater (or each electric auxiliary heating group corresponds to at least one heat exchange tube), and each electric auxiliary heating group includes a plurality of electric auxiliary heating sheets with the same resistance.

[0051] The difference Δt (first temperature difference) between the heat exchange temperature of different heat exchange tubes and the average heat exchange temperature is obtained, and the electric auxiliary heating group corresponding to the heat exchange tube is controlled based on the first temperature difference of each heat exchange tube.

[0052] By adopting the solution of this embodiment, the target electric auxiliary heating group corresponding to the heat exchange tube is controlled through the first temperature difference between the heat exchange temperature of each heat exchange tube and the average heat exchange temperature, so as to avoid uneven air outlet temperature when the heat exchange tube of the air conditioner is heated, thereby improving the comfort of air conditioning heating.

[0053] Optionally, controlling the target electric auxiliary heating group according to the first temperature difference includes: determining whether the first temperature difference is greater than a first threshold; if the first temperature difference is greater than the first threshold, controlling the target electric auxiliary heating group to an off state; if the first temperature difference is less than or equal to the first threshold, controlling the target electric auxiliary heating group to an on state.

[0054] Optionally, the value range of the first threshold is: 0℃~4℃, and it can also be adjusted according to the temperature difference between the indoor temperature and the set temperature. For example, if 3℃ is selected, when the first temperature difference is greater than the first threshold, the target electric auxiliary heating group is not turned on and is in the off state. Only when the first temperature difference is less than or equal to the first threshold, the target electric auxiliary heating group is controlled to heat and is in the on state.

[0055] By adopting the solution of this embodiment, by setting a first threshold and judging whether the first temperature difference is greater than the first threshold, the air conditioner can be controlled to only turn on the electric auxiliary heating group corresponding to the heat exchange tube whose first temperature difference is less than or equal to the first threshold, so as to reduce the number of electric auxiliary heating groups turned on in the electric auxiliary heater, and reduce the overall energy consumption of the electric auxiliary heater, thereby solving the problem of high power consumption of electric auxiliary heating of the air conditioner and achieving energy saving of the air conditioner.

[0056] In one embodiment, controlling the target electric auxiliary heating group to be in an on state includes: determining whether the first temperature difference is greater than a second threshold, wherein the second threshold is less than the first threshold; if the first temperature difference is greater than the second threshold, controlling a first number of electric auxiliary heating sheets in the target electric auxiliary heating group to be in an on state; if the first temperature difference is less than or equal to the second threshold, controlling a second number of electric auxiliary heating sheets in the target electric auxiliary heating group to be in an on state, wherein the target electric auxiliary heating group includes a plurality of electric auxiliary heating sheets, and the second number is greater than the first number.

[0057] In this embodiment, the number of electric auxiliary heating plates turned on is negatively or positively correlated with the first temperature difference. When the electric auxiliary heating plates need to be turned on, the heat exchange temperature of the corresponding heat exchange tube is lower than the average heat exchange temperature (the first temperature difference is a negative number) or close to the average heat exchange temperature, and the outlet air temperature of the corresponding heat exchange tube is low. The electric auxiliary heating plates need to be turned on to assist in heating and increase the outlet hot air temperature. Therefore, the lower the heat exchange temperature of the heat exchange tube, the smaller the first temperature difference, and the more electric auxiliary heating plates need to be turned on.

[0058] Optionally, the first temperature difference is set to Δt, the first threshold is t3, the second threshold is t2, the value range of t2 is: -4℃~0℃, such as -3℃; the value range of t3 is: 0℃~4℃, such as 3℃.

[0059] In an implementation scenario, it is judged that t3 < Δt, if so, the electric auxiliary heating group corresponding to this temperature heat exchange tube does not start the electric auxiliary heating plate, otherwise, continue to judge t2 < Δt ≤ t3, if so, the electric auxiliary heating group corresponding to this temperature heat exchange tube starts one electric auxiliary heating plate, otherwise, continue to judge t1 < Δt ≤ t2, if so, the electric auxiliary heating row corresponding to this temperature U tube starts two electric auxiliary heating plates, otherwise, the electric auxiliary heating row corresponding to this temperature U tube starts three electric auxiliary heating plates. The value range of t1 is: -8℃~-4℃, and can be selected as -6℃.

[0060] By adopting the solution of this embodiment, the number of electric auxiliary heating plates in the target electric auxiliary heating group that are turned on can be reduced by controlling the number of electric auxiliary heating plates that are turned on in the target electric auxiliary heating group, and the overall energy consumption of a single electric auxiliary heating group can be reduced, thereby solving the problem of high power consumption of electric auxiliary heating of air conditioners and further achieving energy saving of air conditioners.

[0061] In another embodiment, controlling the target electric auxiliary heating group to be in an on state includes: calculating the heating power of the target electric auxiliary heating group based on the first temperature difference, wherein the heating power is positively correlated with the first temperature difference; and starting the target electric auxiliary heating group according to the heating power.

[0062] In this embodiment, the target electric auxiliary heating group can adjust the heating power by flexibly adjusting heating devices such as resistors. When the target electric auxiliary heating group includes multiple electric auxiliary heating sheets, the heating power of the target electric auxiliary heating group can also be controlled by controlling the number of turned-on electric auxiliary heating sheets.

[0063] When the electric auxiliary heating plate needs to be turned on, the heat exchange temperature of the corresponding heat exchange tube is lower than the average heat exchange temperature (the first temperature difference is a negative number) or close to the average heat exchange temperature, and the outlet air temperature of the corresponding heat exchange tube is low. The electric auxiliary heating plate needs to be turned on to assist in heating and increase the outlet hot air temperature. Therefore, the lower the heat exchange temperature of the heat exchange tube, the smaller the first temperature difference, and the greater the heating power of the electric auxiliary heating group is required.

[0064] By adopting the solution of this embodiment, the heating power consumption of the target electric auxiliary heating group can be controlled by controlling the heating power of the electric auxiliary heating sheet in the target electric auxiliary heating group, the overall energy consumption of a single electric auxiliary heating group can be reduced, the problem of high power consumption of electric auxiliary heating of air conditioners can be solved, and air conditioning energy saving can be further achieved.

[0065] In this embodiment, before controlling the electric auxiliary heating state of the corresponding position of the air conditioner based on each heat exchange temperature and the average heat exchange temperature, it also includes: obtaining the indoor temperature and set temperature of the air conditioner; calculating the second temperature difference between the set temperature and the indoor temperature; configuring the start-up condition of the electric auxiliary heater according to the second temperature difference, wherein the start-up condition is used to indicate the numerical range of the first temperature difference when the target electric auxiliary heating group of the electric auxiliary heater is turned on, and the first temperature difference is the temperature difference between the heat exchange temperature of the target heat exchange tube corresponding to the target electric auxiliary heating group and the average heat exchange temperature.

[0066] The second temperature difference = the set temperature - the indoor temperature. The maximum value (upper limit) of the numerical range is positively correlated with the second temperature difference, that is, under the same set temperature, the smaller the real-time indoor temperature is, the larger the second temperature difference is, and the higher the temperature at which the electric auxiliary heating group is turned on is.

[0067] By adopting the solution of this embodiment, the start-up conditions of the electric auxiliary heater are configured by setting the second temperature difference between the set temperature and the indoor temperature. This can take into account the current set temperature and heating effect of the air conditioner, and give priority to using the heat exchanger with higher energy efficiency in the air conditioner for heating, thereby improving the energy efficiency of the air conditioner.

[0068] Optionally, configuring the start-up conditions of the electric auxiliary heater according to the second temperature difference includes: determining whether the second temperature difference is less than or equal to a third threshold; if the second temperature difference is less than or equal to the third threshold, configuring the highest temperature in the numerical range to be the first temperature; if the second temperature difference is greater than the third threshold, configuring the highest temperature in the numerical range to be the second temperature, wherein the first temperature is lower than the second temperature.

[0069] In one example, the second temperature difference is set to ΔT, and the first temperature difference is set to Δt, then the difference Δt between the heat exchange temperature of different heat exchange tubes and the average heat exchange temperature and the difference ΔT between the set temperature and the indoor temperature are obtained. If ΔT≤T1 (such as 5°C), the electric auxiliary heating group is started when Δt≤t3 (such as 3°C); if T1<ΔT≤T2 (such as 8°C), the electric auxiliary heating group is started when Δt≤t4 (such as 6°C); if ΔT>T2, the electric auxiliary heating group is started when Δt≤t5 (such as 9°C).

[0070] By adopting the solution of this embodiment, the maximum temperature of the electric auxiliary heating group for turning on the electric auxiliary heater is configured according to the size of the second temperature difference, which can prevent the air conditioner from entering the electric auxiliary heating state too early in the initial stage of heating, thereby improving the energy efficiency of the air conditioner.

[0071] The present embodiment provides an air conditioner, which can dynamically adjust the start and stop of the electric auxiliary heating plates at different positions of the electric auxiliary heater according to the difference ΔT between the set temperature and the indoor temperature and the difference Δt between different U-tube temperatures and the average temperature of the U-tube, thereby effectively improving the uneven heating air outlet temperature phenomenon and greatly improving the heating comfort of the air conditioner.

[0072] Figure 4 is a control flow chart of the electric auxiliary heater in an embodiment of the present invention, including:

[0073] Step a: The air conditioner is turned on for heating, and it is determined whether the air conditioner meets the auxiliary heating start-up conditions. If not, the air conditioner continues to operate in the current mode. If so, the difference Δt between the temperature of different U tubes (heat exchange tubes) and the average temperature of the U tubes and the difference ΔT between the set temperature and the indoor temperature are obtained. If ΔT≤T1, the process proceeds to step b; if T1<ΔT≤T2, the process proceeds to step c; if T2<ΔT, the process proceeds to step d;

[0074] Step b: Continue to judge whether t3 is less than Δt (3°C). If so, the electric auxiliary heat row corresponding to the temperature U tube does not start the electric auxiliary heat sheet. Otherwise, continue to judge whether t2 (-3°C) is less than Δt ≤ t3 (3°C). If so, the electric auxiliary heat row corresponding to the temperature U tube starts one electric auxiliary heat sheet. Otherwise, continue to judge whether t1 (-6°C) is less than Δt ≤ t2 (-3°C). If so, the electric auxiliary heat row corresponding to the temperature U tube starts two electric auxiliary heat sheets. Otherwise, the electric auxiliary heat row corresponding to the temperature U tube starts three electric auxiliary heat sheets. After this step is completed, return to step a.
