Based on the hardware architecture of the air conditioner, the embodiment of the control method of the air conditioner is provided.
Referring to fig. 2, fig. 2 is a first embodiment of a control method of an air conditioner according to the present invention, the control method of the air conditioner includes the steps of:
step S10, detecting that the air conditioner is stopped due to the fact that the air conditioner reaches a high-temperature protection condition in a heating mode, and acquiring the initial rotating speed of the indoor fan before stopping the air conditioner.
Specifically, as shown in fig. 3, the air conditioner includes an indoor unit 10 and an outdoor unit 20, the indoor unit 10 includes an indoor heat exchanger 11 and an indoor fan 12, and the outdoor unit 20 includes an outdoor heat exchanger 21, an outdoor fan 22, a four-way valve 23, a compressor 24 and an electronic expansion valve 25.
Alternatively, the indoor heat exchanger 11 may be provided with a temperature sensor, alternatively, the temperature sensor is provided on a coil of the indoor heat exchanger 11 for detecting a coil temperature, alternatively, the temperature sensor is provided on the indoor unit 10 for detecting an indoor temperature.
Alternatively, the outdoor heat exchanger 21 may be provided with a temperature sensor for detecting an outdoor temperature.
Under the overload heating condition, the temperature of the indoor heat exchanger of the air conditioner is high due to the fact that the load of the air conditioner is high, and in order to enable the air conditioner to normally operate, if the frequency of the compressor is reduced, the compressor is easy to stall, and abnormal shutdown is caused. In addition, in the automatic air mode, as the indoor temperature rises, the air outlet speed of the indoor unit is reduced to 1% at the lowest, hot air is easy to float upwards, so that return air short circuit is caused, the load of the air conditioner is further increased, and the temperature-reaching shutdown is caused, or the indoor heat exchanger, namely the evaporator in the heating mode, is stopped under the condition of high-temperature protection.
Under the heating mode, the air conditioner is detected to stop because of reaching the high-temperature protection condition, the initial rotating speed of the indoor fan before the air conditioner stops is obtained, and at the moment, the initial rotating speed of the indoor fan can not meet the heat dissipation requirement of the indoor heat exchanger. When the air conditioner is stopped, the temperature of the indoor heat exchanger can be gradually reduced. Optionally, before step S10, in the heating mode, the coil temperature of the indoor heat exchanger is detected, and when the coil temperature is greater than a preset temperature, the protection against high Wen Tingji is triggered, and the preset temperature is 60 degrees, for example.
And S20, starting the air conditioner after stopping the air conditioner for a preset time period, and operating according to a target rotating speed, wherein the target rotating speed is determined according to the preset rotating speed and the initial rotating speed.
Specifically, after the air conditioner is stopped for a preset time period, optionally, the preset time period is 180s. Restarting the air conditioner and operating at a target rotational speed, optionally, the target rotational speed is determined according to a preset rotational speed and an initial rotational speed, and the following formula is exemplary:
L2＝L1+Lb；
wherein L2 is a target rotation speed, L1 is an initial rotation speed, lb is a preset rotation speed, and preset rotation speeds of different models correspond to different set values, optionally lb=100. After triggering the high temperature protection condition, the rotating speed lower limit value of the indoor fan is improved, thereby being beneficial to improving the condition of return air short circuit and improving the use comfort of users.
Optionally, after step S20, when the air conditioner is stopped again due to reaching the high temperature protection condition, the air conditioner is started after stopping for a preset period of time, and is operated according to the target rotation speed determined when stopping for the first time. Optionally, the preset duration may be the same as the preset duration of the last shutdown, and optionally, the preset duration may be greater than the preset duration of the last shutdown. So as to prevent the noise of the indoor unit from increasing more and more due to the continuous increase of the rotating speed, and therefore, the target rotating speed is still maintained even when the high-temperature shutdown protection is triggered again.
Optionally, after step S20, when the air conditioner is stopped again due to reaching the high temperature protection condition, the target rotation speed L2 of the indoor fan before the air conditioner is stopped is obtained, the air conditioner is started after stopping for a preset time period, the air conditioner is started, and is operated according to the updated target rotation speed L3, and the updated target rotation speed L3 is determined according to the preset rotation speed Lb and the target rotation speed L3, and the following formula is shown:
L3＝L2+Lb；
wherein, L3 is the updated target rotation speed, L2 is the target rotation speed, lb is the preset rotation speed, and preset rotation speeds of different models correspond to different set values, optionally, lb=100. The temperature of the indoor heat exchanger can be reduced at a relatively high speed, so that heating load can be reduced, the frequent start-stop condition caused by high-temperature stop protection of the evaporator under overload working conditions is improved, and the use comfort of a user is improved.
Step S20 is also performed at the same time: alternatively, the first indoor temperature and the first outdoor temperature are detected, and when the first indoor temperature is less than or equal to the first temperature threshold value, or the first outdoor temperature is less than or equal to the second temperature threshold value, it means that the load of the air conditioner is reduced due to the reduction of the indoor or outdoor ambient temperature, and the load of the indoor heat exchanger is reduced, so that the target rotation speed is updated to the preset minimum rotation speed. The minimum rotating speed is set by a program, and the target rotating speed is larger than or equal to the minimum rotating speed.
Alternatively, the first temperature threshold may be preset. Optionally, before step S40, acquiring a second indoor temperature of the air conditioner before stopping; and determining a first temperature threshold according to the second indoor temperature and a preset first temperature value. Illustratively, the following formula is shown:
T1＝T10-Ta；
wherein T1 is a first temperature threshold, T10 is a second indoor temperature, ta is a preset first temperature value, and optionally ta=2.
Alternatively, the second temperature threshold may be preset. Optionally, before step S60, acquiring a second outdoor temperature of the air conditioner before shutdown; and determining a second temperature threshold according to the second outdoor temperature and a preset second temperature value. Illustratively, the following formula is shown:
T2＝T20-Tb；
wherein T2 is a second temperature threshold, T20 is a second indoor temperature, tb is a preset first temperature value, and optionally, tb=2.
In the technical scheme of the embodiment, the air conditioner is stopped and restarted to run at the target rotating speed, so that the temperature of the indoor heat exchanger in the air conditioner is reduced rapidly, heating load can be reduced, frequent start-stop conditions caused by high-temperature stop protection of the indoor heat exchanger under overload working conditions are improved, indoor temperature is not reduced rapidly, and use comfort of users is improved.
Referring to fig. 4, fig. 4 is a second embodiment of the control method of the air conditioner according to the present invention, based on the first embodiment, the following steps are performed at the same time as the step S20:
step S30, detecting a first indoor temperature;
and step S40, when the first indoor temperature is less than or equal to a first temperature threshold value, updating the target rotating speed to a preset minimum rotating speed.
Specifically, the first indoor temperature is a real-time indoor temperature when the air conditioner operates at a target rotational speed, and the first indoor temperature can be detected by a temperature sensor installed on the indoor unit.
When the first indoor temperature is less than or equal to a first temperature threshold value, the indoor environment temperature is reduced, so that the load of the air conditioner is reduced, the load of the indoor heat exchanger is reduced, and therefore the target rotating speed is updated to a preset minimum rotating speed, wherein the minimum rotating speed is set by a program, and the target rotating speed is greater than or equal to the minimum rotating speed.
Alternatively, the first temperature threshold may be preset.
Optionally, before step S40, acquiring a second indoor temperature of the air conditioner before stopping; and determining a first temperature threshold according to the second indoor temperature and a preset first temperature value. Illustratively, the following formula is shown:
T1＝T10-Ta；
wherein T1 is a first temperature threshold, T10 is a second indoor temperature, ta is a preset first temperature value, and optionally ta=2.
In the technical scheme of the embodiment, when the first indoor temperature is smaller than or equal to the first temperature threshold, the load of the indoor heat exchanger is reduced, the locking of the target rotating speed is released, the target rotating speed is updated to be the preset minimum rotating speed, and energy consumption is saved.
Referring to fig. 5, fig. 5 is a third embodiment of a control method of an air conditioner according to the present invention, based on the second embodiment, after the step S30, further includes:
step S50, detecting a first outdoor temperature when the first indoor temperature is greater than a first temperature threshold;
and step S60, updating the target rotating speed to a preset minimum rotating speed when the first outdoor temperature is less than or equal to a second temperature threshold value.
Specifically, when the first indoor temperature is greater than the first temperature threshold, it indicates that the load of the indoor heat exchanger does not drop to a proper range at this time, and the first outdoor temperature is detected, where the first outdoor temperature is a real-time outdoor environment temperature, and the first outdoor temperature may be detected by a temperature sensor installed on the outdoor unit.
When the first outdoor temperature is less than or equal to the second temperature threshold, the outdoor environment temperature is reduced, the load of the air conditioner is reduced, the load of the indoor heat exchanger is reduced, and therefore the target rotating speed is updated to be a preset minimum rotating speed according to an automatic wind operation mode, wherein the minimum rotating speed is set by a program, and the target rotating speed is greater than or equal to the minimum rotating speed.
Alternatively, the second temperature threshold may be preset.
Optionally, before step S60, acquiring a second outdoor temperature of the air conditioner before shutdown; and determining a second temperature threshold according to the second outdoor temperature and a preset second temperature value. Illustratively, the following formula is shown:
T2＝T20-Tb；
wherein T2 is a second temperature threshold, T20 is a second indoor temperature, tb is a preset first temperature value, and optionally, tb=2.
In the technical scheme of the embodiment, when the first indoor temperature is greater than the first temperature threshold and the first outdoor temperature is less than or equal to the second temperature threshold, the decrease of the environmental temperature is indicated at the moment, so that the load of the air conditioner is decreased, the locking of the target rotating speed is released, the target rotating speed is updated to be the preset minimum rotating speed, and the energy consumption is saved.
