Referring to fig. 2, an embodiment of the present application provides an air conditioner control method, which is mainly applied to the air conditioner 100 in fig. 1, and the method includes steps S201 to S203, specifically as follows:
s210, collecting indoor temperature.
The indoor temperature refers to the ambient temperature of the environment where the indoor unit of the air conditioner is located, and specifically, a first temperature sensor may be arranged in the indoor unit of the air conditioner, so as to detect the current ambient temperature of the environment where the indoor unit is located in real time through the first temperature sensor.
Specifically, after the air conditioner is turned on and operates in a heating mode for a period of time, the air conditioner acquires the indoor temperature at the current moment through an indoor temperature sensor.
And S220, if the indoor temperature is greater than the preset temperature threshold value, acquiring the coil temperature of an outdoor coil of the air conditioner.
Wherein, predetermine the temperature threshold value and can set up according to actual conditions, for example can set up to the human temperature value that feels comfortable (for example, 22 degrees centigrade) or the temperature value that the user set up, avoid the air conditioner not realize refrigeration or heat the function and carry out the adjustment of air conditioner operating parameter immediately and lead to indoor temperature can't reach predetermined temperature threshold value, improve the practicality of air conditioner, promote user's use and experience.
Wherein, the outdoor coil refers to the coil of the heat exchanger of the outdoor unit; specifically, a second temperature sensor may be provided in an outdoor unit of the air conditioner, and the coil temperature of the outdoor coil may be detected in real time by the second temperature sensor. It can be understood that when the temperature of the coil of the outdoor side coil is lower than the outdoor environment temperature, the moisture in the outdoor air can be condensed on the surface of the outdoor side coil, so that the operation parameters of the air conditioner need to be adjusted, the temperature of the outdoor side coil is increased, and the frosting of the outdoor side coil is avoided.
And S230, if the temperature of the coil pipe is less than the frost point temperature, adjusting the rotating speed of a fan of the air conditioner and the running frequency of the compressor until the temperature of the coil pipe is greater than the frost point temperature.
The frost point temperature refers to the temperature of air cooled to saturation under the condition that the water vapor content and the air pressure are not changed. When the coil temperature of the outdoor side coil is lower than the frost point temperature, moisture in the outdoor air is condensed on the surface of the outdoor side coil. Therefore, in the operation process of the air conditioner, when the temperature of the coil pipe of the outdoor side coil pipe is lower than the frost point temperature, the rotating speed of the air blower, the operation frequency of the compressor and the like can be adjusted to improve the temperature of the coil pipe of the outdoor side coil pipe, so that the temperature of the coil pipe is higher than the frost point temperature, the frosting condition is reduced, and the frostless operation of the heating mode of the air conditioner is realized.
Further, in one embodiment, before collecting the coil temperature of the outdoor side coil of the air conditioner, the method further comprises: and collecting the outdoor temperature, and determining the frost point temperature according to the outdoor temperature.
The outdoor temperature refers to the ambient temperature of the environment where the outdoor unit of the air conditioner is located; specifically, a third temperature sensor may be disposed in the outdoor unit of the air conditioner, and the current ambient temperature of the environment in which the outdoor unit is located may be detected in real time by the third temperature sensor. Specifically, after the outdoor temperature is obtained, the frost point temperature at the corresponding outdoor temperature may be calculated under the condition that the outdoor relative humidity is a preset relative humidity value.
For example, the preset rh value may be set to 85%, and the frost point temperature at the outdoor temperature is calculated under the condition that the outdoor rh is 85%.
By acquiring the real-time outdoor temperature and then calculating the frost point temperature in real time according to the outdoor temperature, the operation parameters of the air conditioner can be adjusted according to the real-time frost point temperature when the operation parameters of the air conditioner are adjusted subsequently, the air conditioner is prevented from frosting as much as possible, and the heating performance of the air conditioner is improved.
In one embodiment, if the coil temperature is less than the frost point temperature, adjusting the fan speed of the air conditioner and the compressor operating frequency until the coil temperature is greater than the frost point temperature comprises: if the temperature of the coil pipe is less than the frost point temperature, controlling and adjusting the rotating speed of a fan of the air conditioner; if the adjusted rotating speed of the fan reaches a preset rotating speed threshold value, acquiring the coil temperature of an outdoor coil of the air conditioner; and if the temperature of the coil pipe is lower than the frost point temperature, controlling the running frequency of the compressor to adjust until the temperature of the coil pipe is higher than the frost point temperature.
The preset rotating speed threshold value refers to the maximum value or the minimum value of the adjustable range of the rotating speed of the fan.
Specifically, when the temperature of the coil of the outdoor coil is lower than the frost point temperature, the rotating speed of the fan of the air conditioner is controlled and adjusted firstly, the temperature of the coil of the outdoor coil is collected again after the adjusted rotating speed of the fan is operated for a first preset time, and if the temperature of the coil of the outdoor coil is still lower than the frost point temperature, the rotating speed of the fan is controlled and adjusted again. After the rotating speed of the fan is controlled and adjusted for multiple times, if the temperature of the coil of the outdoor side coil is still less than the frost point temperature and the rotating speed of the fan is detected to reach the preset rotating speed threshold value, the running frequency of the compressor of the air conditioner can be controlled and adjusted to achieve the purpose of adjusting the indoor environment temperature of the current environment until the temperature of the coil of the outdoor side coil reaches the temperature which is more than or equal to the frost point temperature.
It can be understood that, after the fan rotation speed of the air conditioner is controlled and adjusted, if the acquired coil temperature of the outdoor coil is greater than or equal to the frost point temperature, the adjustment of the fan rotation speed of the air conditioner and the operation frequency of the compressor is stopped, and the air conditioner continues to operate at the adjusted fan rotation speed, so that the frostless operation of the air conditioner in the heating mode is realized.
More specifically, the air conditioner includes an indoor fan and an outdoor fan; in one embodiment, if the coil temperature is less than the frost point temperature, controlling and adjusting the fan speed of the air conditioner may include: and if the temperature of the coil pipe is less than the frost point temperature, controlling to increase the rotating speed of a first fan of the outdoor fan and reduce the rotating speed of a second fan of the indoor fan until the rotating speed of the first fan reaches a maximum rotating speed threshold and the rotating speed of the second fan reaches a minimum rotating speed threshold.
When the rotating speed of the fan is controlled and adjusted, the rotating speed of the second fan of the indoor fan can be controlled and reduced, and then the rotating speed of the first fan of the outdoor fan can be controlled and increased; or the rotating speed of the first fan of the outdoor fan can be controlled to be increased first, and then the rotating speed of the second fan of the indoor fan can be controlled to be reduced; the second fan speed of the indoor fan may be reduced while the first fan speed of the outdoor fan is controlled to be increased, which is not limited herein.
The preset rotating speed threshold comprises a maximum rotating speed threshold and a minimum rotating speed threshold, and when the rotating speed of the first fan of the outdoor fan reaches the maximum rotating speed threshold, the adjustment of the rotating speed of the first fan of the outdoor fan is stopped; and when the rotating speed of the second fan of the indoor fan reaches the minimum rotating speed threshold value, stopping adjusting the rotating speed of the second fan of the indoor fan.
It can be understood that, for example, when the rotation speed of the first fan of the outdoor fan is controlled to be increased and the rotation speed of the second fan of the indoor fan is controlled to be decreased, if the rotation speed of the first fan of the outdoor fan reaches the maximum rotation speed threshold value but the rotation speed of the second fan of the indoor fan does not reach the minimum rotation speed threshold value, the adjustment of the rotation speed of the first fan of the outdoor fan is stopped, but the rotation speed of the second fan of the indoor fan is continuously adjusted until the rotation speed of the second fan reaches the minimum rotation speed threshold value; similarly, if the second fan rotating speed of the indoor fan reaches the minimum rotating speed threshold value but the first fan rotating speed of the outdoor fan does not reach the maximum rotating speed threshold value, the adjustment of the second fan rotating speed of the indoor fan is stopped, but the first fan rotating speed of the outdoor fan is continuously adjusted until the first fan rotating speed reaches the maximum rotating speed threshold value.
Further, a first revolution step length and a second revolution step length can be set, if the coil temperature of the coil pipe of the outdoor unit is less than the frost point temperature, the rotating speed of the fan of the outdoor unit is increased by the first revolution step length, and/or the rotating speed of the second fan of the indoor unit is decreased by the second revolution step length; and then, running the adjusted fan at the rotating speed of the fan for a first preset time, collecting the temperature of the coil pipe of the outdoor unit coil pipe again, if the temperature of the coil pipe of the outdoor unit coil pipe is still smaller than the frost point temperature, increasing the rotating speed of the fan of the outdoor unit at the first rotating speed step length again, and/or reducing the rotating speed of a second fan of the indoor unit at a second rotating speed step length until the rotating speed of the first fan reaches a maximum rotating speed threshold value and/or the rotating speed of the second fan reaches a minimum rotating speed threshold value. Wherein, the first revolution step and the second revolution step may be equal or unequal.
For example, the first rotation speed step length and the second rotation speed are both 100 revolutions, and the first preset time period is 30 seconds; if the coil temperature of the coil pipe of the outdoor unit is lower than the frost point temperature, increasing the rotating speed of a first fan of the outdoor unit by 100 revolutions, and simultaneously reducing the rotating speed of a second fan of the indoor unit by 100 revolutions; then, after the operation is performed for 30 seconds at the adjusted fan rotation speed (including the adjusted first fan rotation speed of the outdoor unit and the adjusted second fan rotation speed of the indoor unit), the coil temperature of the coil of the outdoor unit is collected again, if the coil temperature of the coil of the outdoor unit is still less than the frost point temperature, the first fan rotation speed of the outdoor unit is increased by 100 revolutions again, and meanwhile, the second fan rotation speed of the indoor unit is reduced by 100 revolutions until the first fan rotation speed reaches the maximum fan rotation speed and the second fan rotation speed reaches the minimum fan rotation speed.
In one embodiment, if the coil temperature is less than the frost point temperature, controlling the compressor operating frequency to adjust until the coil temperature is greater than the frost point temperature comprises: if the coil temperature is less than the frost point temperature, the compressor operating frequency is reduced until the coil temperature is greater than the frost point temperature.
Specifically, after the operation frequency of the compressor is adjusted each time, the operation frequency of the compressor is operated for a second preset time period after the operation frequency is adjusted, the temperature of the coil pipe of the outdoor side coil pipe is collected again, if the temperature of the outdoor side coil pipe is still less than the frost point temperature, the operation frequency of the compressor is continuously adjusted until the temperature of the outdoor side coil pipe is greater than or equal to the frost point temperature, and at this time, the operation frequency of the compressor is stopped being adjusted.
More specifically, a frequency adjustment step can be set, and if the coil temperature of the outdoor unit coil is less than the frost point temperature, the running frequency of the compressor is reduced by the frequency adjustment step; and then, running the compressor at the regulated running frequency for a second preset time, collecting the temperature of the coil pipe of the outdoor unit coil pipe again, and if the temperature of the coil pipe of the outdoor unit coil pipe is still less than the frost point temperature, reducing the running frequency of the compressor at the frequency adjustment step length again until the temperature of the coil pipe is greater than the frost point temperature.
For example, the frequency adjustment step length is set to 10 hz, and the second preset time length is 10 minutes; if the coil temperature of the outdoor unit coil is lower than the frost point temperature, the running frequency of the compressor is reduced by 10 Hz; and then, after the adjusted running frequency of the compressor is operated for 10 minutes, the temperature of the coil pipe of the outdoor unit coil pipe is collected again, and if the temperature of the coil pipe of the outdoor unit coil pipe is still lower than the frost point temperature, the running frequency of the compressor is reduced by 10 Hz again until the temperature of the coil pipe is higher than the frost point temperature.
The rotating speed of a fan of the air conditioner and the running frequency of the compressor are adjusted, the temperature of the coil pipe of the outdoor coil pipe is increased, the temperature of the coil pipe is larger than the frost point temperature, and the coil pipe of the outdoor unit is prevented from frosting.
Further, in one embodiment, in the process of adjusting the fan rotation speed and the compressor operation frequency of the air conditioner, the air conditioner collects the indoor temperature in real time, and if the indoor temperature is smaller than a preset temperature threshold, the fan rotation speed and the compressor operation frequency of the air conditioner are stopped, and the air conditioner is controlled to enter a normal heating mode, so that the comfort level of a user is prevented from being influenced by the reduction of the indoor temperature.
In the control method of the air conditioner, the coil temperature of the outdoor coil of the air conditioner is collected by collecting the indoor temperature if the indoor temperature is greater than a preset temperature threshold; if the temperature of the coil pipe is lower than the frost point temperature, the rotating speed of a fan of the air conditioner and the running frequency of the compressor are adjusted until the temperature of the coil pipe is higher than the frost point temperature. When the indoor temperature is higher than the preset temperature threshold value in the air conditioner running process, the coil temperature of the outdoor side coil is taken as a main control target, the fan rotating speed and the compressor running frequency of the air conditioner are adjusted, the coil temperature of the outdoor side coil is higher than the frost point temperature while the indoor temperature is controlled to be higher than the preset temperature threshold value, the indoor temperature is guaranteed to be stable, and the outdoor unit is prevented from frosting.
In addition, in one embodiment, the air conditioner control method provided by the present application further includes obtaining a preset temperature, and when the indoor temperature reaches the preset temperature, controlling the air conditioner to enter a temperature-reaching shutdown mode. Specifically, the preset temperature may be an expected temperature set by a user when the air conditioner is turned on, the air conditioner detects the indoor temperature, and when the indoor temperature reaches the preset temperature and meets a temperature-reaching shutdown condition, the air conditioner enters the temperature-reaching shutdown to avoid heat waste.
The air conditioner control method will be further described below with reference to fig. 3. As shown in fig. 3, the air conditioner control method is divided into three stages, each of which operates in a different mode, specifically as follows:
the first stage, heating mode:
1. starting up and running: the air conditioner is started to operate.
2. Heating operation: after the air conditioner runs in a heating mode for a preset heating time (for example, 5-10 minutes), the current indoor temperature T is collected through a first temperature sensor built in an indoor unitInner ring。
3. And (3) detecting the indoor temperature: for indoor temperature TInner ringA determination is made as to whether less than 22 degrees celsius.
When indoor temperature TInner ringIf the temperature is lower than 22 ℃, continuing to operate in a heating mode; circularly collecting the current indoor temperature T after running the preset heating timeInner ringAnd for the indoor temperature TInner ringJudging whether the temperature is lower than 22 ℃;
when indoor temperature TInner ringAnd if the temperature is greater than or equal to 22 ℃, the air conditioner enters a second stage, namely a frostless operation mode.
Second stage, frostless operation mode:
1. determining the frost point temperature: after the air conditioner enters a frostless operation mode, the outdoor temperature T is acquired by a temperature sensor built in an outdoor unit1(t) and calculating the outdoor relative humidity according to the preset condition that the outdoor relative humidity is 85 percentIs the frost point temperature T of 85%d(t)。
2. Detecting the temperature of the coil: the air conditioner collects the coil temperature T of the outdoor coil in real time through a temperature sensor of the outdoor coil arranged in the outdoor unit2(T) and for coil temperature T2(T) whether or not it is less than the frost point temperature Td(t) judging.
If coil temperature T2(T) is greater than or equal to the frost point temperature Td(t), the outdoor unit of the air conditioner has no frost wind;
if coil temperature T2(T) less than frost point temperature Td(T), the outdoor machine of the air conditioner has frost wind, at the moment, the steps of adjusting the rotating speed of the fan and the running frequency of the compressor are carried out, and the coil temperature T of the outdoor coil is increased2(t)。
3. Adjusting the rotating speed of a fan and the operating frequency of a compressor:
the fan rotating speed regulation of the outdoor fan and the indoor fan is preferentially carried out, and the coil temperature of the outdoor coil is increased by increasing the first fan rotating speed of the outdoor fan and reducing the second fan rotating speed of the indoor fan. Specifically, the rotating speed of the fan of the outdoor unit is increased by the first rotating speed step length, and the rotating speed of the second fan of the indoor unit is decreased by the second rotating speed step length; then, the fan runs for a first preset time (such as 30 seconds) at the regulated rotating speed of the fan, and the coil temperature T of the coil of the outdoor unit is collected again2(T) if the coil temperature T of the coil of the outdoor unit2(T) is still less than the frost point temperature Td(T), increasing the rotating speed of the fan of the outdoor unit by the first rotating speed step length again, and decreasing the rotating speed of the second fan of the indoor unit by the second rotating speed step length until the coil temperature T2(T) greater than frost point temperature Td(t)。
In the process of adjusting the fan rotating speeds of the outdoor fan and the indoor fan, detecting the fan rotating speeds of the outdoor fan and the indoor fan in real time, if the rotating speed of a first fan of the outdoor fan is increased to the maximum fan rotating speed, and the rotating speed of a second fan of the indoor fan is reduced to the minimum fan rotating speed, but the coil temperature T of the outdoor coil pipe is equal to the coil temperature T of the outdoor coil pipe2(T) is still less than the frost point temperature Td(t) then proceedAnd adjusting the running frequency of the compressor.
Likewise, the compressor running frequency is reduced by the frequency adjustment step; then, the compressor runs for a second preset time length at the adjusted running frequency of the compressor, and the temperature T of the coil pipe of the outdoor unit coil pipe is collected again2(T) if the coil temperature T of the coil of the outdoor unit2(T) is still less than the frost point temperature Td(T), the compressor operating frequency is again decreased by the frequency adjustment step size until the coil temperature T2(T) is greater than or equal to the frost point temperature Td(t)。
It should be noted that when the air conditioner is operated in the frostless operation mode, the real-time indoor temperature T is continuously collectedInner ringAnd detecting the indoor temperature; once room temperature TInner ringIf the temperature is lower than 22 ℃, controlling the air conditioner to exit a frostless operation mode, entering a heating mode, and operating in the heating mode; if indoor temperature TInner ringAnd greater than or equal to 22 degrees celsius, the air conditioner continues to operate in the no-frost operation mode.
And a third stage, reaching a warm-stop mode:
1. judging the shutdown condition when reaching the temperature: real-time indoor temperature T of air conditionerInner ringDetecting when the indoor temperature T isInner ringIf the temperature is high enough and the temperature reaching shutdown condition is met, the air conditioner is controlled to enter the temperature reaching shutdown mode, otherwise, the indoor temperature T is continuously returnedInner ringAnd (4) judging.
The control method of the air conditioner ensures that the indoor environment is above 22 ℃ in one stage, and meets the comfortable requirement of a human body; the air conditioner is controlled to enter a frostless heating mode in the second stage, and the coil temperature T of the coil of the outdoor unit is enabled by monitoring the outdoor temperature in real time2(t) adjusting the operation parameters of the air conditioner along with the outdoor ambient temperature, avoiding frosting of the air conditioner and improving the heating performance of the air conditioner. And the temperature-reaching shutdown is realized in the third stage, so that the waste of heat is avoided.
