Fig. 1 shows an air conditioning control system schematic diagram 100 according to an embodiment of the present application, and referring to fig. 1, the air conditioning control system schematic diagram includes an outdoor unit system and an indoor unit system. The outdoor unit system comprises a compressor, a four-way valve, a condenser, an outdoor fan, a stop valve and an airflow separator, namely the outdoor unit. The indoor system comprises an electronic expansion valve, an evaporator and an indoor fan, namely an indoor unit. Wherein, there can be a plurality of indoor units. In the air conditioner control system, the electric auxiliary heating device can be further included.
In the present application, after the air conditioner acquires the instruction and starts the heating mode, the compressor starts to operate. The refrigerant in the compressor is converted into high-temperature gaseous refrigerant, and the high-temperature gaseous refrigerant flows into an evaporator of the indoor system through the four-way valve. The air conditioner monitors the temperature of the evaporator in real time, if the temperature of the evaporator is higher than a first set temperature, the indoor fan is started, heat in the evaporator is blown out, and the heating effect is achieved.
Because the indoor fan is properly controlled, the refrigerant in the evaporator is cooled by the indoor fan, and a small part of the refrigerant is changed from a gas state to a liquid state and is remained in the evaporator. The other part of the refrigerant continuously flows into the outdoor unit from the evaporator in a gaseous form, so that a large amount of liquid refrigerant is prevented from accumulating in the evaporator, and the low-pressure protection of an outdoor unit system is avoided, and the running stability of the air conditioner is improved.
Meanwhile, in the heating mode, heating can be performed through the electric auxiliary heating device. The electric auxiliary heating device can generate a large amount of heat in a short time by converting electric energy into heat energy when the electric auxiliary heating device is operated, so that the heating effect can be enhanced. Because the electric auxiliary heating device can generate a large amount of heat in a short time, the indoor fan needs to be adjusted to a larger gear in advance. In the heating process of the electric auxiliary heating device, the temperature of the electric auxiliary heating device is very high, and the refrigerant in the evaporator flows into the external machine system in a gaseous form under the cooling of the indoor fan, so that the problem of liquefaction accumulation of the refrigerant in the evaporator can be better solved, and the running stability of the air conditioner is improved.
In addition to the compressor or the electric auxiliary heating device alone, a combination of the compressor and the electric auxiliary heating device may be used for heating. In the process of composite heating, the problem of low-pressure protection of an external machine system caused by accumulation of liquid refrigerant in an evaporator can be solved, the running stability of an air conditioner is improved, the power consumption can be reduced, and the service life of the air conditioner is prolonged.
The present application will be described in detail below:
fig. 2 shows a flowchart of an air conditioner control method in an embodiment of the present application. The air conditioner control method may be performed by a device having a calculation processing function, for example, may be performed by an air conditioner control apparatus. Referring to fig. 2, the air conditioner control method at least includes steps 210 to 250, and is described in detail as follows:
In step 210, a heating mode is initiated in response to a user-triggered control command.
In the application, the air conditioning heating mode can be started according to a control instruction triggered by a user, for example, the air conditioning heating mode can be triggered and started according to a preset temperature set by the user, the actual temperature in the environment can be monitored in the air conditioning operation process, and if the current actual temperature does not meet the preset temperature requirement, the control instruction for starting the heating mode can be triggered. Also for example, the heating mode may be directly activated by the user.
In step 230, in the heating mode, if the compressor is in an on state, the evaporator temperature is obtained.
In the present application, if the compressor is detected to be in an on state, the evaporator temperature is directly acquired to determine whether to turn on the indoor fan according to the evaporator temperature.
In step 250, if the evaporator temperature is greater than a first set temperature, the indoor fan is turned on.
In one embodiment of the present application, the first set temperature may be 20 ℃ to 25 ℃.
For example, when the first set temperature is 25 ℃, the temperature of the evaporator is judged, if the temperature of the evaporator is greater than 25 ℃, the indoor fan is started, and then the heat in the evaporator can be blown out from the air conditioner, so that the heating effect is realized.
In the present application, in the compressor on state, the high-temperature gaseous refrigerant flows through the evaporator, causing the evaporator temperature to rise. If the indoor fan is turned on before the temperature of the evaporator is higher than the first set temperature, two problems are caused, and firstly, the blown heat is insufficient, so that the heating effect is poor. Second, when the high-temperature gaseous refrigerant flows through the evaporator, the refrigerant can be liquefied rapidly, and accumulated in the evaporator, so that the amount of the refrigerant flowing through the external machine system is small, and the air conditioner is protected under low pressure.
In the heating mode, the temperature of the evaporator is obtained by starting the compressor, and the temperature of the current evaporator is monitored. And if the temperature of the current evaporator is higher than the first set temperature, starting the indoor fan. If the temperature of the current evaporator is smaller than the first set temperature, the indoor fan is started, so that the refrigerant in the evaporator is quickly liquefied and accumulated, and the refrigerant cannot flow into the external machine system, so that the low-pressure protection of the external machine system is caused. Therefore, the control of the indoor fan can prevent the refrigerant from being liquefied and accumulated too quickly to trigger the low-pressure protection of the air conditioner, so that the running stability of the air conditioner can be improved.
Next, the present application will take an air conditioner with an electric auxiliary heating function as an example, and based on different situations, details how to control the fan to be turned on and control the electric auxiliary heating device to be turned on:
Fig. 3 shows a flowchart of an air conditioner control method in an on state of an air conditioner electric auxiliary heating function in an embodiment of the present application.
Referring to fig. 3, in one embodiment of the present application, if the electric auxiliary heating function of the air conditioner is in an on state, the air conditioner control method at least includes steps 310 to 330, which are described in detail as follows:
in step 310, if the outdoor unit system of the air conditioner is in an abnormal state, the indoor fan is turned on.
In the application, after the electric auxiliary heating function is started, if the external machine system of the air conditioner is in an abnormal state, the indoor fan is started. In this case, when the external system of the air conditioner is in an abnormal state, the air conditioner cannot perform heating.
Therefore, an electric auxiliary heating device is required for heating. The electric auxiliary heating device can generate a large amount of heat in a short time, so that the air conditioner is damaged and the use experience of a user is affected in order to avoid the accumulation of a large amount of heat in the air conditioner, and the indoor fan is required to be started before the electric auxiliary heating device is started.
In step 330, after the indoor fan is turned on for a first preset time, the electric auxiliary heating device is turned on.
In this application, because the electric auxiliary heating device can produce a large amount of heat in the short time, consequently need in time blow out the heat in the evaporimeter, need indoor fan to provide great wind speed promptly, that is to say, indoor fan needs great rotational speed to realize. The indoor fan cannot be lifted to a proper rotating speed from 0 in a short time, so that the indoor fan needs to be started in advance and operated for a period of time, and the indoor fan can reach the proper rotating speed.
In some embodiments of the present application, the first preset time may be 0 seconds to 5 seconds.
For example, after the indoor fan is turned on for 5 seconds, the rotational speed of the indoor fan has reached an appropriate rotational speed. At this time, the electric auxiliary heating device is started, so that a great amount of heat can be prevented from accumulating in the air conditioner, the damage to the air conditioner is avoided, the use experience of a user is not reduced, and a good heating effect is realized.
Fig. 4 shows another flowchart of an air conditioner control method in an on state of an air conditioner electric auxiliary heating function in an embodiment of the present application.
Referring to fig. 4, in one embodiment of the present application, if the electric auxiliary heating function of the air conditioner is in an on state, the air conditioner control method at least includes steps 410 to 430, which are described in detail as follows:
in step 410, if the outdoor unit system of the air conditioner is in a normal state and the compressor is in a closed state, the indoor fan is turned on.
In the application, after the electric auxiliary heating function is determined to be started, if the external machine system of the air conditioner is in a normal state and the compressor is in a closed state, the indoor fan is started. Although the outdoor unit system of the air conditioner is in a normal state, the compressor is in a closed state, and thus the air conditioner cannot perform heating.
In this case, an electric auxiliary heating device is required for heating. The electric auxiliary heating device can generate a large amount of heat in a short time, so that the air conditioner is prevented from being damaged and the use experience of a user is not reduced, and the indoor fan is required to be started before the electric auxiliary heating device is started.
In step 430, after the indoor fan is turned on for a first preset time, the electric auxiliary heating device is turned on.
In this application, because the electric auxiliary heating device can produce a large amount of heat in the short time, consequently need in time blow out the heat in the evaporimeter, need indoor fan to provide great wind speed promptly, that is to say, indoor fan needs great rotational speed to realize. The indoor fan cannot be lifted to a proper rotating speed from 0 in a short time, so that the indoor fan needs to be started in advance and operated for a period of time, and the indoor fan can reach the proper rotating speed.
In some embodiments of the present application, the first preset time may be 0 seconds to 5 seconds.
For example, after the indoor fan is turned on for 5 seconds, the rotational speed of the indoor fan has reached an appropriate rotational speed. At this time, the electric auxiliary heating device is started, so that a great amount of heat can be prevented from accumulating in the air conditioner, the damage to the air conditioner is avoided, the use experience of a user is not reduced, and a good heating effect is realized.
Fig. 5 shows another flowchart of an air conditioner control method in an on state of an air conditioner electric auxiliary heating function in an embodiment of the present application.
Referring to fig. 5, in one embodiment of the present application, if the electric auxiliary heating function of the air conditioner is in an on state, the air conditioner control method at least includes steps 510 to 550, which are described in detail as follows:
in step 510, if the external system of the air conditioner is in a normal state and the compressor is in an on state, the evaporator temperature is obtained.
In the application, after the electric auxiliary heating function is determined to be started, if the external machine system of the air conditioner is in a normal state and the compressor is in a starting state, the temperature of the evaporator is obtained. At this time, the air conditioner can perform normal heating through the compressor, and meanwhile, the electric auxiliary heating device can be started to perform auxiliary heating based on actual requirements.
In step 530, if the evaporator temperature is greater than the first set temperature and less than the second set temperature, and the air conditioner is in a non-frosting state, and the indoor environment temperature is less than the third set temperature, the indoor fan is turned on.
In the application, the opening of the indoor fan is controlled by judging the temperature of the evaporator, the air conditioning state and the indoor environment temperature. And if the temperature of the evaporator is higher than the first set temperature and lower than the second set temperature, the air conditioner is in a non-defrosting state, and the indoor environment temperature is lower than the third set temperature, the indoor fan is started. The first set temperature may be 20 ℃ to 25 ℃, the second set temperature may be 50 ℃ to 60 ℃, the third set temperature may be the sum of a user set temperature and a fluctuation value, the user set temperature may be 25 ℃ to 30 ℃, and the fluctuation value may be 0 ℃ to 5 ℃.
Because, when the evaporator temperature is greater than the first set temperature and less than the second set temperature, the start of the compressor is indicated, the generated high-temperature refrigerant flows through the evaporator, and a certain amount of heat is accumulated in the evaporator, but the heat accumulation time is slower, and the heating time is too long, so that the auxiliary heating can be performed by starting the electric auxiliary heating device, and the heating time is shortened.
Meanwhile, when the air conditioner is in a non-defrosting state, the air conditioner is not required to perform defrosting operation. Because the defrosting process and the heating process cannot be performed simultaneously in the air conditioner. Therefore, if the air conditioner is required to perform heating, it is required to perform the heating in a non-frosting state.
In addition, when the indoor environment temperature is smaller than the third set temperature, the indoor environment temperature is too low, and the temperature requirement of a user is not met, so that the auxiliary heating can be performed by starting the electric auxiliary heating device, the indoor environment temperature is increased, the requirement of the user is met, and the heating efficiency and the heating effect of the original air conditioner can be improved.
For example, the temperature obtained from the evaporator is 26 ℃, the first set temperature is 23 ℃, the second set temperature is 52 ℃, the air conditioner is in a non-defrosting state, the indoor environment temperature is 5 ℃, the third set temperature is 31 ℃, wherein the user set temperature is 26 ℃, and the fluctuation value is 5 ℃. And by analyzing the parameters and the states, the conditions for starting the indoor fan are met, namely the indoor fan is started immediately.
Also for example, the temperature obtained from the evaporator is 28 ℃, the first set temperature is 25 ℃, the second set temperature is 55 ℃, the air conditioner is in a defrosting state, the indoor environment temperature is-1 ℃, the third set temperature is 32 ℃, wherein the user set temperature is 28 ℃, and the fluctuation value is 4 ℃. By analyzing the parameters and the states, the condition that the indoor fan is started is not met because the air conditioner is in a defrosting state.
Also for example, the temperature obtained from the evaporator is 55 ℃, the first set temperature is 25 ℃, the second set temperature is 51 ℃, the air conditioner is in a non-defrosting state, the indoor environment temperature is 10 ℃, the third set temperature is 32 ℃, wherein the user set temperature is 28 ℃, and the fluctuation value is 4 ℃. By analyzing the parameters and the states, the temperature of the evaporator is higher than the second set temperature, and the condition of starting the indoor fan is not met.
In step 550, after the indoor fan is turned on for a first preset time, the electric auxiliary heating device is turned on.
In this application, because the electric auxiliary heating device can produce a large amount of heat in the short time, consequently need in time blow out the heat in the evaporimeter, need indoor fan to provide great wind speed promptly, that is to say, indoor fan needs great rotational speed to realize. The indoor fan cannot be lifted to a proper rotating speed from 0 in a short time, so that the indoor fan needs to be started in advance and operated for a period of time, and the indoor fan can reach the proper rotating speed.
In some embodiments of the present application, the first preset time may be 0 seconds to 5 seconds.
For example, after the indoor fan is turned on for 5 seconds, the rotational speed of the indoor fan has reached an appropriate rotational speed. At this time, the electric auxiliary heating device is started, so that a great amount of heat can be prevented from accumulating in the air conditioner, the damage to the air conditioner is avoided, the use experience of a user is not reduced, and a good heating effect is realized.
Further, before step 550, that is, before if the evaporator temperature is greater than the first set temperature and less than the second set temperature, and the air conditioner is in a non-frosting state and the indoor environment temperature is less than the third set temperature, the method may further include step 531:
in step 531, if the air conditioner is in the non-heating mode, or the electric auxiliary heating function of the air conditioner is in the non-starting state, or the evaporator temperature is less than or equal to the first set temperature, or the air conditioner is in the defrosting state, or the evaporator temperature is greater than or equal to the second set temperature, or the indoor environment temperature is greater than or equal to the third set temperature, the heating mode is restarted.
In this application, for the above step 531, it should be noted that, first, the air conditioner is in the heating mode, which is a precondition for executing the embodiments of the present application, if the air conditioner is in the non-heating mode, the air conditioner cannot realize the function of heating, that is, the indoor fan cannot be controlled to rotate, so as to provide effective heating. Therefore, the heating mode needs to be restarted.
Second, the electric auxiliary heating function of the air conditioner is in an opening state, which is a precondition for opening the electric auxiliary heating device, and the electric auxiliary heating function of the air conditioner is in an unopened state, and even if other conditions for opening the electric auxiliary heating device are judged to be met, the electric auxiliary heating device cannot be opened, so that the heating efficiency of the air conditioner cannot be accelerated and the heating effect can be improved through the electric auxiliary heating device. Therefore, the heating mode needs to be restarted.
Third, if the evaporator temperature is equal to or lower than the first set temperature, it means that the evaporator temperature is abnormal, and effective heating cannot be provided, and the heating mode needs to be restarted.
Fourth, if the air conditioner is in a defrosting state, that is, because the indoor temperature is too low, frost is formed on the surface of the evaporator, defrosting operation is required to be performed on the frost by the air conditioner, and at this time, the air conditioner cannot perform defrosting and heating operations at the same time. Therefore, the heating mode needs to be restarted.
Fifth, if the temperature of the evaporator is greater than or equal to the second set temperature, it indicates that the temperature of the evaporator is abnormal, that is, the temperature in the evaporator is too high, so that good heating cannot be provided and air conditioning equipment cannot be protected, and the use experience of a user is reduced, so that the heating mode needs to be restarted.
Sixth, if the indoor environment temperature is greater than or equal to the third set temperature, it is indicated that the current indoor environment temperature meets the temperature required by the user, and heating is not needed. Therefore, it is necessary to interrupt the heating process, restart the heating mode, and determine whether or not it is necessary to continue heating.
In the application, abnormal conditions in the air conditioner control process can be avoided by setting the triggering condition for restarting the heating mode, so that the stability of the air conditioner in the operation process can be improved.
Further, after step 550, i.e. after turning on the electric auxiliary heating apparatus, step 551 may further include:
in step 551, if the evaporator temperature is less than the first set temperature within a second preset time after the compressor is in an on state, the indoor fan is turned off.
In the application, after the compressor is started, high-temperature refrigerant can be generated and flows through the evaporator, so that the heating effect is realized. If the evaporator temperature is less than the first set temperature (e.g., 24 c) for a second preset time period when the compressor is on, it is indicated that the heat in the evaporator is insufficient to achieve the set heating effect, and therefore, the indoor fan needs to be turned off, or the rotational speed of the indoor fan needs to be reduced, so that the heat in the evaporator is maintained at a proper level.
The second preset time may be 120 seconds to 300 seconds. The second preset time is set for a long time because a buffer time is required from the off to the steady, normal operation state of the compressor and the buffer time is long.
Further, after step 550, i.e. after turning on the electric auxiliary heating device, step 552 may be further included:
in step 552, if the indoor ambient temperature is less than the third set temperature and the operating frequency of the compressor is less than the set frequency, the electric auxiliary heating device is turned off and the operating frequency of the compressor is increased in accordance with the set ratio.
In this application, after a period of time for heating the air conditioner, if the indoor environment temperature is less than the third set temperature (for example, may be 30 ℃), it is indicated that the heating efficiency of the air conditioner is low and the heating effect is not good. Meanwhile, if the operation frequency of the compressor is smaller than the set frequency, the compressor does not reach the set operation state, namely, the heating efficiency and the heating effect of the air conditioner can be improved by improving the operation frequency of the compressor.
Therefore, the electric auxiliary heating device can be turned off in advance, and the operation frequency of the compressor can be increased according to the set proportion by setting the current operation frequency of the compressor. In addition, after the operation frequency of the compressor is increased and the heating is performed for a period of time, it may be continuously determined whether the indoor environment temperature is less than the third set temperature. If the indoor environment temperature is still less than the third set temperature, at the moment, the electric auxiliary heating device can be started to perform the combined heating of the compressor and the electric auxiliary heating device.
The third set temperature may be a sum of a user set temperature and a fluctuation value, the user set temperature may be 25 ℃ to 30 ℃, and the fluctuation value may be 0 ℃ to 5 ℃. Meanwhile, the set proportion may be 1% -20%.
For example, when the current indoor environment temperature is 27 ℃, the third set temperature is 30 ℃, the operation frequency of the compressor is 50Hz, and the set frequency is 55Hz, the operation frequency of the compressor can be improved according to the proportion of 10% by turning off the electric auxiliary heating device, so that the effect and the efficiency of air conditioning heat are improved.
After the operation frequency of the compressor is increased based on the set ratio, if the increased operation frequency of the compressor exceeds the maximum operation frequency of the compressor, the compressor is operated according to the maximum operation frequency of the compressor.
Further, after step 330 shown in fig. 3, or after step 430 shown in fig. 4, or after step 550 shown in fig. 5, step 560 may be further included:
in step 560, if the air conditioner receives a non-heating mode operation instruction, or receives an electric auxiliary heating function closing instruction, or receives an indoor fan closing instruction, or the air conditioner is in a defrosting state, or the evaporator temperature is continuously higher than the second set temperature in a third preset time, or the indoor environment temperature is continuously higher than the third set temperature in the third preset time, or an abnormal signal appears in an indoor system of the air conditioner, the electric auxiliary heating device is closed.
In this application, in the above step 560, it should be noted that, first, the air conditioner is in the heating mode and is a precondition for heating, and if the air conditioner receives the non-heating mode operation command, it is noted that the heating process needs to be immediately interrupted, and therefore, the electric auxiliary heating device needs to be turned off.
Second, the electric auxiliary heating function is started as a precondition for realizing the heating of the electric auxiliary heating device, and if an electric auxiliary heating function closing instruction is received, the electric auxiliary heating device is closed.
Thirdly, the indoor fan is in an open state and is a necessary ring in the heating process, if an indoor fan closing instruction is received, heat in the evaporator cannot be discharged in time, and damage to an air conditioner can be caused, so that after the indoor fan closing instruction is received, the electric auxiliary heating device needs to be closed.
Fourth, if the air conditioner is in a defrosting state, that is, because the indoor temperature is too low, frost is formed on the surface of the evaporator, defrosting operation is required to be performed on the frost by the air conditioner, and at this time, the air conditioner cannot perform defrosting and heating operations at the same time, so that the electric auxiliary heating device needs to be turned off.
Fifth, if the evaporator temperature is continuously higher than the second set temperature (for example, may be 55 ℃) within the third preset time (for example, may be 40 seconds), it means that the heat accumulation in the evaporator is excessive and the heat cannot be timely discharged, so that the electric auxiliary heating device needs to be turned off, and the heat accumulation in the evaporator is reduced, so that a good heating effect can be achieved.
Sixth, if the indoor environment temperature is continuously higher than the third set temperature (for example, may be 29 ℃) within the third preset time (for example, may be 45 seconds), it is indicated that the air conditioner heat reaches the set temperature of the user, and the expected heating effect of the user is achieved, and therefore, the electric auxiliary heating device needs to be turned off.
Seventh, if an abnormal signal appears in the indoor system of the air conditioner, it indicates that the air conditioner controls the indoor fan, monitors the temperature of the evaporator, monitors the indoor temperature and acquires inaccurate control parameters of other air conditioners, and the inaccurate control causes poor heating effect, causes damage to the air conditioner and reduces the use experience of users. Therefore, the electric auxiliary heating device needs to be turned off.
In order to enable those skilled in the art to better understand the present application, a control flow for turning on the electric auxiliary heat function and a control flow for turning off the electric auxiliary heat function will be described in specific embodiments with reference to fig. 6 and 7.
Referring to fig. 6, a flowchart for turning on electric auxiliary heat in the embodiment of the present application is shown, and specific steps are as follows:
first, when the air conditioner is operated, judging whether the air conditioner is operated in a heating mode, if not, re-operating the air conditioner, and re-judging whether the air conditioner is operated in the heating mode.
And secondly, judging whether the electric auxiliary heating function of the air conditioner is started after the air conditioner is determined to be in the heating mode, and if the electric auxiliary heating function of the air conditioner is not started, restarting the air conditioner and judging whether the air conditioner is started in the heating mode again.
And thirdly, judging whether the air conditioner external unit system is abnormal after the electric auxiliary heating function of the air conditioner is determined to be started, and judging whether the indoor fan is abnormal if the air conditioner external unit system is in an abnormal state. If the indoor fan is not abnormal, the electric auxiliary heating device is started after the indoor fan is started for s1, otherwise, the air conditioner is restarted, and whether the heating mode of the air conditioner is started is judged again. The s1 time is a first preset time and may be 0 seconds to 5 seconds.
And step four, judging whether the compressor is started after the external machine system is determined to be abnormal, and judging whether the indoor fan is abnormal if the compressor is not started. If the indoor fan is not abnormal, the electric auxiliary heating device is started after the indoor fan is started for s1, otherwise, the temperature of the evaporator is judged. The s1 time is a first preset time and may be 0 seconds to 5 seconds.
And fifthly, judging the temperature of the evaporator after confirming that the compressor is started, judging whether the air conditioner is in a defrosting state if the temperature of the evaporator is larger than t1 and smaller than t1, otherwise, restarting the air conditioner and judging whether the air conditioner is in a heating mode again. Wherein t1 is a first set temperature, and t2 is a second set temperature.
And firstly, judging whether the air conditioner is in a defrosting state after the evaporator temperature is determined to be greater than t1 and less than t1, if the air conditioner is in a non-defrosting state, judging the indoor environment temperature, otherwise, restarting the air conditioner, and judging whether the air conditioner is in a heating mode again.
And sixthly, judging the indoor environment temperature after the air conditioner is determined to be in a non-defrosting state, and judging whether the indoor fan is abnormal or not if the indoor environment temperature is smaller than t 3. If the indoor fan is not abnormal, the electric auxiliary heating device is started after the indoor fan is started for s1, otherwise, the air conditioner is restarted, and whether the heating mode of the air conditioner is started is judged again. Wherein t3 is a third set temperature. The s1 time is a first preset time and may be 0 seconds to 5 seconds.
Referring to fig. 7, a flowchart of turning off the electric auxiliary heat in the embodiment of the present application is shown, where fig. 7 includes fig. 7 (a), fig. 7 (b) and fig. 7 (c), and specific steps are as follows:
after the air conditioner turns on the electric auxiliary heating device, the electric auxiliary heating device can be controlled to be turned off through different conditions.
For example, in fig. 7 (a), if the air conditioner is in the non-heating mode, or the electric auxiliary heating function is turned off, or the indoor fan is turned off, or the evaporator is continuously at a third preset time (s 3 in the figure) and is greater than the second set temperature (t 2 in the figure), or the air conditioner is in the defrosting state, or the indoor environment temperature is continuously at a third preset time (s 3 in the figure) and is greater than the third set temperature (t 3 in the figure), or the indoor system is in an abnormal state, the electric auxiliary heating device is turned off, otherwise, the electric auxiliary heating device is kept in a state of electric auxiliary heating operation.
Also for example, in fig. 7 (b), if the indoor ambient temperature is less than the third set temperature (i.e., t3 in the figure), and the operating frequency of the compressor is less than the maximum frequency, the electric auxiliary heating device is turned off, and otherwise, the electric auxiliary heating operation state is maintained.
For example, in fig. 7 (c), if the temperature of the evaporator is lower than the first set temperature (i.e., t1 in the figure) within the second preset time (i.e., s2 in the figure) when the compressor is started, the electric auxiliary heating device is turned off, otherwise, the electric auxiliary heating device is kept in a working state.
