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 increasingly 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 electronic expansion valve opening of the air conditioner are different, which will cause different pressures corresponding to each flow path of the indoor heat exchanger, and then cause different refrigerant flow rates in different flow paths, causing differences in the U-tube temperatures of different flow paths. In addition, the refrigerant temperatures inside the U-tubes at the inlet end, outlet end, and middle part of each flow path are all different. Generally, during heating, the U-tube temperature at the inlet section is higher than the U-tube temperature in the middle section, and higher than the U-tube temperature at the outlet end. This is due to the continuous heat exchange of the refrigerant during the flow path operation. The above reasons show that when the air conditioner is heating, different U-tubes will produce obvious temperature differences due to their position in the flow path and the influence of different working conditions, which will cause uneven heating outlet temperature of the air conditioner, affecting the comfort of the air conditioner.

[0003] To prevent the phenomenon of cold air blowing caused by uneven heating air outlet temperatures, conventional electric auxiliary heaters are often used to increase the air outlet temperature. However, these commonly used electric auxiliary heaters only increase the overall air outlet temperature, failing to effectively address the uneven heating air outlet temperature. Furthermore, they can lead to excessively high air outlet temperatures and increased power consumption.

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

[0037] In the embodiment, a heating control method of an air conditioner is provided, Figure 2 FIG. 1 is a flowchart of a heating control method of an air conditioner according to an embodiment of the present application, which includes the following steps: Figure 2 as shown in the figure, the flowchart includes the following steps:

[0038] In step S202, when the air conditioner is in an electric auxiliary heating mode, a plurality of heat exchange temperatures of the air conditioner are obtained, wherein the indoor heat exchanger of the air conditioner includes a plurality of heat exchange pipes, and each heat exchange pipe corresponds to a heat exchange temperature.

[0039] Optionally, the electric auxiliary heating mode of the air conditioner can be manually started based on a control instruction of a user, or can be automatically started when the air conditioner meets an auxiliary heating starting condition.

[0041] In step S204, a heat exchange average temperature of the heat exchanger is calculated based on the plurality of heat exchange temperatures.

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

[0043] In step S206, an electric auxiliary heating state of a corresponding position of the air conditioner is controlled based on each heat exchange temperature and the heat exchange average temperature.

[0044] Optionally, each heat exchange pipe of each heat exchange temperature corresponds to an electric auxiliary heating state, and the electric auxiliary heating state includes at least starting an electric auxiliary heating group of the corresponding position and stopping an electric auxiliary heating group of the corresponding position.

[0045] By the above steps, in the case that the air conditioner is started in the electric auxiliary heating mode, a plurality of heat exchange temperatures of the air conditioner are obtained, wherein the indoor unit heat exchanger of the air conditioner comprises a plurality of heat exchange pipes, each heat exchange pipe corresponds to a heat exchange temperature; the heat exchange average temperature of the heat exchanger is calculated according to the plurality of heat exchange temperatures; and the electric auxiliary heating state of the corresponding position of the air conditioner is controlled based on each heat exchange temperature and the heat exchange average temperature. By using the heat exchange average temperature of the plurality of heat exchange pipes of the air conditioner and the heat exchange temperature of each heat exchange pipe to control the electric auxiliary heating state of the corresponding position of the air conditioner, the electric auxiliary heating of the corresponding position can be started or stopped based on the temperature state of each heat exchange pipe, thereby solving the technical problem of uneven air outlet temperature of the air conditioner in the related art, and improving the user comfort of air conditioning heating.

[0046] In the embodiment, the control of the electric auxiliary heating state of the corresponding position of the air conditioner based on each heat exchange temperature and the heat exchange average temperature comprises: for each target heat exchange pipe of the indoor unit heat exchanger, calculating a first temperature difference between the heat exchange temperature of the target heat exchange pipe and the heat exchange average temperature; determining a target electric auxiliary heating group corresponding to the target heat exchange pipe in the electric auxiliary heater of the air conditioner, wherein the electric auxiliary heater comprises a plurality of electric auxiliary heating groups, and each heat exchange pipe 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 pipe is any heat exchange pipe in the indoor unit heat exchanger.

[0048] The first temperature difference is equal to the heat exchange temperature of the target heat exchange pipe minus the heat exchange average temperature.

[0049] Figure 3 is a schematic diagram of an electric auxiliary heater and an indoor unit heat exchanger in an embodiment of the present application. The indoor unit heat exchanger comprises a plurality of heat exchange pipes, the heat exchange pipe is a U-shaped heat dissipation pipe, the heat exchange pipe is also called a U pipe or a heat exchanger pipe, each U pipe has a temperature detector, the temperature detector is fixed in the middle of the U pipe (or can be fixed on both sides of the U pipe), the electric auxiliary heater comprises a plurality of electric auxiliary heating groups (electric auxiliary heating units), each U pipe can correspond to an electric auxiliary heating group of the electric auxiliary heater, the corresponding electric auxiliary heater and electric auxiliary heating group have the same air outlet position, and each row of the electric auxiliary heater has a plurality of electric auxiliary heating fins with fixed and same power or adjustable power.

[0050] The indoor unit heat exchanger of the air conditioner in the embodiment comprises a plurality of flow paths, each flow path comprises at least one heat exchange pipe (U pipe), each U pipe 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 pipe), and each electric auxiliary heating group comprises a plurality of electric auxiliary heating fins with the same resistance.

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

[0052] By using the scheme of the embodiment, the target electric auxiliary heating group corresponding to each 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 that the air outlet temperature is uniform when the heat exchange tube of the air conditioner is heating, and the heating comfort of the air conditioner is improved.

[0053] Optionally, the control of the target electric auxiliary heating group according to the first temperature difference comprises: judging whether the first temperature difference is greater than a first threshold value; if the first temperature difference is greater than the first threshold value, controlling the target electric auxiliary heating group to be in a closed state; and if the first temperature difference is less than or equal to the first threshold value, controlling the target electric auxiliary heating group to be in an open state.

[0054] Optionally, the first threshold value is in a range of 0-4℃, and can be adjusted according to the temperature difference between the indoor temperature and the set temperature, for example, 3℃. In the judgment of whether the first temperature difference is greater than the first threshold value, the target electric auxiliary heating group is in the closed state. Only when the first temperature difference is less than or equal to the first threshold value, the target electric auxiliary heating group is controlled to be in the open state.

[0055] By setting the first threshold value and judging whether the first temperature difference is greater than the first threshold value, the air conditioner can be controlled to be in the open state only when the first temperature difference of the heat exchange tube is less than or equal to the first threshold value, the number of the electric auxiliary heating groups in the electric auxiliary heater can be reduced, the overall energy consumption of the electric auxiliary heater can be reduced, the problem of high power consumption of the electric auxiliary heater of the air conditioner can be solved, and the energy saving of the air conditioner is realized.

[0056] In one embodiment, the control of the target electric auxiliary heating group to be in the open state comprises: judging whether the first temperature difference is greater than a second threshold value, wherein the second threshold value is less than the first threshold value; if the first temperature difference is greater than the second threshold value, controlling a first number of electric auxiliary heating fins of the target electric auxiliary heating group to be in the open state; and if the first temperature difference is less than or equal to the second threshold value, controlling a second number of electric auxiliary heating fins of the target electric auxiliary heating group to be in the open state, wherein the target electric auxiliary heating group comprises a plurality of electric auxiliary heating fins, and the second number is greater than the first number.

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

[0058] Optionally, the first temperature difference is Δt, the first threshold is t3, and the second threshold is t2, the value of t2 is in the range of -4℃ to 0℃, for example, -3℃; the value of t3 is in the range of 0℃ to 4℃, for example, 3℃.

[0059] In one implementation scenario, it is determined that t3 < Δt, if yes, the electric auxiliary heating sheet corresponding to the electric auxiliary heating group of the temperature heat exchange pipe is not started, otherwise, it is determined that t2 < Δt ≤ t3, if yes, one electric auxiliary heating sheet corresponding to the electric auxiliary heating group of the temperature heat exchange pipe is started, otherwise, it is determined that t1 < Δt ≤ t2, if yes, two electric auxiliary heating sheets corresponding to the electric auxiliary heating row of the temperature U pipe are started, otherwise, three electric auxiliary heating sheets corresponding to the electric auxiliary heating row of the temperature U pipe are started. The value of t1 is in the range of -8℃ to -4℃, for example, -6℃.

[0060] By adopting the scheme of the embodiment, the number of the electric auxiliary heating sheets in the target electric auxiliary heating group can be reduced, the overall energy consumption of a single electric auxiliary heating group can be reduced, the problem of high power consumption of the electric auxiliary heating of the air conditioner is solved, and energy saving of the air conditioner is further realized.

[0061] In another implementation, controlling the target electric auxiliary heating group to be in the open state includes: calculating a 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 implementation, the target electric auxiliary heating group can adjust the heating power by flexibly adjusting the heating resistor and other heating devices, and when the target electric auxiliary heating group includes multiple electric auxiliary heating sheets, the number of the electric auxiliary heating sheets that are started can be controlled to control the heating power of the target electric auxiliary heating group.

[0063] When the electric auxiliary heating sheet needs to be started, the heat exchange temperature of the corresponding heat exchange pipe is lower than the average heat exchange temperature (the first temperature difference is negative) or close to the average heat exchange temperature, the outlet air temperature of the corresponding heat exchange pipe is low, the electric auxiliary heating sheet needs to be started to assist heating to increase the outlet air temperature, therefore, the lower the heat exchange temperature of the heat exchange pipe, the smaller the first temperature difference, and the greater the heating power of the electric auxiliary heating group.

[0064] By adopting the scheme of the embodiment, the heating power of the electric auxiliary heating sheet in the target electric auxiliary heating group can be controlled, the heating power consumption of the target electric auxiliary heating group can be controlled, the overall energy consumption of a single electric auxiliary heating group can be reduced, the problem of high power consumption of the electric auxiliary heating of the air conditioner is solved, and energy saving of the air conditioner is further realized.

[0065] In the embodiment, before controlling the electric auxiliary heating state of the corresponding position of the air conditioner based on each heat exchange temperature and the heat exchange average temperature, the method further comprises: obtaining an indoor temperature and a set temperature of the air conditioner; calculating a second temperature difference between the set temperature and the indoor temperature; and configuring an opening condition of the electric auxiliary heater according to the second temperature difference, wherein the opening condition is used to indicate a numerical range of a first temperature difference when a target electric auxiliary heating group of the electric auxiliary heater is turned on, and the first temperature difference is a temperature difference between a heat exchange temperature of a target heat exchange pipe corresponding to the target electric auxiliary heating group and the heat exchange average temperature.

[0066] The second temperature difference is equal to the set temperature minus the indoor temperature. A maximum value (an upper limit value) of the numerical range is positively correlated with the second temperature difference, that is, in the case of the same set temperature, the smaller the real-time indoor temperature, the greater the second temperature difference, and the greater the temperature of the electric auxiliary heating group that is turned on.

[0067] By configuring the opening condition of the electric auxiliary heater according to the second temperature difference between the set temperature and the indoor temperature, the current set temperature and the heating effect of the air conditioner can be considered, the heat exchanger with a higher energy efficiency in the air conditioner is preferentially used for heating, and the energy efficiency of the air conditioner is improved.

[0068] Optionally, configuring the opening condition of the electric auxiliary heater according to the second temperature difference comprises: determining whether the second temperature difference is less than or equal to a third threshold value; if the second temperature difference is less than or equal to the third threshold value, configuring a highest temperature of the numerical range as a first temperature; and if the second temperature difference is greater than the third threshold value, configuring the highest temperature of the numerical range as a second temperature, wherein the first temperature is less than the second temperature.

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

[0070] By configuring the highest temperature of the electric auxiliary heating group that is turned on according to the size of the second temperature difference, the air conditioner can be prevented from entering the electric auxiliary heating condition too early in the initial heating stage, and the energy efficiency of the air conditioner is improved.

[0071] The embodiment provides an air conditioner which can dynamically adjust the starting and closing of electric auxiliary heating pieces at different positions of an electric auxiliary heater according to a difference AT between a set temperature and an indoor temperature and a difference At between different U tube temperatures and an average U tube temperature, so that the phenomenon of uneven heating air outlet temperature is effectively improved, and air conditioner heating comfort is greatly improved.
