Referring to fig. 2, in an embodiment of the method for controlling an air conditioner of the present invention, the method for controlling an air conditioner includes the steps of:
s10, acquiring outdoor environment temperature and operation parameters of an air conditioner, wherein the operation parameters comprise at least one of shutdown time and exhaust temperature;
in order to reduce the friction force of each part of the air conditioner during operation and improve the service life of the compressor of the air conditioner, lubricating oil is generally arranged in the compressor of the air conditioner.
The lubricating oil is very important in the compressor system, and is just like the blood of a human body, the compressor can normally run and is always in a good state, and the lubricating oil plays an important role in lubricating all parts. The lubricating oil is required to maintain good lubricating performance, the working temperature of the lubricating oil is one of the decisive factors, and the temperature of the lubricating oil is required to be kept within a normal range when the compressor works, so that the lubricating oil can play a good lubricating role. The physical characteristics of the lubricating oil enable the viscosity of the lubricating oil to be more remarkable along with the change of temperature, the viscosity is reduced when the temperature is increased, the viscosity is increased when the temperature is reduced, however, the temperature of the compressor is different under different working conditions in the working process, the temperature of the lubricating oil is inseparable from the ambient temperature of the running of a unit, and in order to enable the compressor to normally run under the low-temperature limit working condition, the abrasion is reduced, so that the condition that the compressor can stably and reliably run is ensured that the lubricating oil of the compressor has proper viscosity and the temperature of the lubricating oil is in a normal range. Because the outdoor unit is generally arranged outdoors, when the outdoor environment temperature is low and the compressor downtime is long, the viscosity of the lubricating oil is extremely high, even the lubricating oil is frozen. Thereby causing the air conditioner to fail to operate normally.
In this embodiment, the air conditioner is provided with a temperature sensor on the outdoor unit to obtain the outdoor ambient temperature. Alternatively, the temperature sensor may be provided separately from the outdoor unit and communicatively connected to the air conditioner through a wireless and/or wired connection. So that the air conditioner can read and/or receive the outdoor ambient temperature detected by the temperature sensor. The air conditioner can also establish communication connection with a server or other terminals, so that the outdoor environment temperature can be acquired through the server or other terminals.
For example, when the air conditioner acquires the outdoor ambient temperature through the server, a real-time outdoor ambient temperature request instruction may be transmitted to the server. When the server receives the real-time outdoor environment temperature request instruction, the server may first determine a geographic location corresponding to the outdoor unit of the air conditioner according to the real-time outdoor environment temperature request instruction, and then query real-time weather forecast data corresponding to the geographic location, which is stored in the server or another server, according to the geographic location. And determining the real-time outdoor environment temperature corresponding to the geographic position according to the real-time weather forecast data. And then sending the real-time outdoor ambient temperature to the air conditioner. For the air conditioner to determine the outdoor ambient temperature.
Further, the air conditioner can also acquire the self operating parameters in real time. Wherein the operation parameter includes at least one of a shutdown duration and an exhaust temperature of the air conditioner.
Specifically, the air conditioner is provided with a timer, and when the air conditioner executes a shutdown action to stop the operation of the compressor, the timer starts to time. So that the air conditioner can read the real-time timing value in the timer as the stop-time duration.
The air conditioner can also be provided with the temperature detection sensor who is located exhaust duct or air exit to make the air conditioner can pass through temperature detection sensor acquires self exhaust temperature.
S20, determining a first time length and/or a first temperature according to the outdoor environment temperature;
in this embodiment, after the air conditioner obtains the outdoor ambient temperature, the first temperature and/or the first duration may be determined according to the outdoor ambient temperature. And the first temperature and/or the first time length are/is set as a threshold value for judging whether the air conditioner preheats the compressor.
Specifically, when the outdoor ambient temperature T is acquired S The first temperature T may be determined according to the following formula Y :
T Y ＝kT S +γ
Where k and γ are adjustment values, which are fixed constant values previously stored in the air conditioner. For example, k may be set to any one of (0, 2), e.g., 0.5, 1, 1.1, 1.2, or 1.3, etc., and γ may be set to any one of (-5, 15), e.g., -2, 3, 5, or 12, etc.
When the outdoor environment temperature is acquired, the temperature interval in which the outdoor environment temperature is located may also be determined first. Each temperature interval may be associated with a predetermined time period. After the temperature interval in which the outdoor environment temperature is located is determined, the associated duration of the temperature interval may be obtained as the first duration.
Illustratively, the interval length of the temperature interval may be set to 2 ℃, 3 ℃, or 5 ℃ or the like, and may also be set to other values. The interval length of the temperature interval can be set by the manufacturer of the air conditioner in a user-defined mode according to the requirement. This example is explained with the interval length of the temperature interval set to 2 ℃. The air conditioner can be provided with a plurality of temperature ranges of [ -2, 0), [ -4, -2), [ -6, -4) \ 8230 [ \ 8230 [ -32, -30), etc. When the obtained outdoor environment temperature is not-5 ℃, the preset time length associated with the temperature interval [ -4, -6) can be obtained as the first time length. For example, when the acquired outdoor environment temperature is less than-5 ℃ and the preset time duration associated with the temperature interval [ -4, -6) is 1.5h, the first time duration is 1.5h.
It is understood that the preset time length associated with the temperature intervals can be set by the air conditioner manufacturer according to the requirement, and the above example is not used to limit the number of the temperature intervals set by the air conditioner and the specific value of the preset time length associated with each temperature interval.
It should be noted that, the temperature interval and the associated preset temperature satisfy the following conditions: the larger the temperature value corresponding to the temperature interval is, the smaller the preset time associated with the temperature interval is.
Optionally, in order to save the system overhead of the air conditioner, after the outdoor ambient temperature is obtained, it may be determined whether the outdoor ambient temperature is less than or equal to a first threshold value. When the outdoor ambient temperature is less than or equal to the first threshold, the step S20 is performed. Otherwise, the air conditioner does not respond. Wherein, the first threshold value is a fixed value pre-stored in the air conditioner. For example, it may be set to any value of (-5,5) ° c. For example, it may be set to-3 deg.C, -1 deg.C, -0 deg.C, -2 deg.C or 3 deg.C, etc.
And S30, when the exhaust temperature is judged to be lower than the first temperature and/or the shutdown duration is judged to be longer than the first duration, controlling the air conditioner to preheat a compressor.
In this embodiment, after determining the first temperature and/or the first duration, it may be determined whether the exhaust temperature is less than the first temperature and/or the shutdown duration is greater than the first duration.
And when the exhaust temperature is judged to be lower than the first temperature and/or the shutdown time is judged to be longer than the first time, controlling the air conditioner to preheat the compressor.
Specifically, a heating device may be disposed on a compressor of the air conditioner, and the compressor may be preheated by the heating device, so as to increase the temperature of the lubricating oil in the compressor and reduce the viscosity of the lubricating oil.
Alternatively, the heating device may be provided as a stator coil, which may be in direct contact with the rotor crankshaft of the compressor. Because the rotor crankshaft of the compressor is a heat conductor, the heat emitted by the rotor coil can be transferred to an oil sump of the compressor to heat lubricating oil in the compressor.
The heating device can also be a heating belt wrapped on the shell of the compressor. When the heat generating belt generates heat, the heat may be conducted to the lubricating oil through a casing of the compressor. Thereby heating the lubricating oil of the compressor. The heating belt can realize the heating purpose through heating modes such as resistance wire heating, ceramic heater, resistance coil heating, quartz tube heating and the like.
As an implementation manner, the heating device may also be an electromagnetic heating device, since the shell of the compressor is generally made of metal material, and a metal coil is also present inside the compressor. Therefore, when the heating device is an electromagnetic heating device, eddy current can be generated on the shell or the inner metal through the change of the magnetic field, and then heat is generated. Thereby achieving the effect of heating the compressor.
In the technical scheme disclosed in this embodiment, an outdoor environment temperature and an operation parameter of an air conditioner are obtained first, wherein the operation parameter includes at least one of a shutdown duration and an exhaust temperature, then a first duration and/or a first temperature are determined according to the outdoor environment temperature, and when it is determined that the exhaust temperature is less than the first temperature, and/or the shutdown duration is greater than the first duration, the air conditioner is controlled to preheat a compressor. The compressor of the air conditioner can be preheated, so that the effect of preventing the air conditioner from being incapable of being started in an extreme environment is achieved. Meanwhile, the first time length and the first temperature can be adjusted according to the outdoor environment temperature, so that the preheating time of the air conditioner on the compressor can be more accurately determined, and the effects of reducing the energy consumption of the air conditioner and improving the energy efficiency grade of the air conditioner are achieved.
Further, referring to fig. 3, based on the above embodiment, in another embodiment, after the step S30, the method further includes:
and S40, controlling the air conditioner to stop preheating the compressor when the condition of stopping preheating is met.
In this embodiment, the stop warm-up condition may include at least one of:
starting the compressor;
the outdoor ambient temperature is greater than a second threshold;
the exhaust temperature is greater than a second temperature;
the preheating time period of the compressor is longer than the second time period.
Specifically, after the compressor starts to operate, the air conditioner may be controlled to stop heating the compressor after the start of compression because the compressor generates heat during operation.
When the compressor is shut down, the temperature of the compressor must be greater than or equal to the current outdoor ambient temperature. That is, the lubricating oil in the compressor may be greater than or equal to the indoor temperature. Therefore, when the outdoor ambient temperature is greater than the second threshold value, the temperature of the lubricating oil is within the allowable range. The heating of the compressor can be stopped. When the discharge temperature is greater than the second temperature, it may be determined that the compressor temperature of the air conditioner is within the allowable temperature range, and thus the air conditioner is controlled to stop heating the compressor. When the preheating time of the compressor is longer than the second time, in order to avoid overheating the compressor, the air conditioner may be controlled to stop heating the compressor.
It should be noted that the second threshold may be determined according to the first threshold, and the second threshold is greater than the first threshold. Wherein the second threshold value may be calculated according to the following formula:
D2＝D1+m
wherein D2 is a second threshold, D1 is a first threshold, and m is a fixed constant. The settings may be customized. Can be set to any value of [1, 10], such as 2, 6, 7 or 9, etc.
The second temperature and the second time period may be determined according to the outdoor ambient temperature.
Specifically, a plurality of outdoor environment temperature intervals may be set, and then the temperature interval in which the outdoor environment temperature is located is determined, and then each temperature interval may be associated with a second time period. When the outdoor environment temperature is obtained, a second time length associated with a temperature interval in which the outdoor environment temperature is located may be obtained.
The second temperature may be calculated according to the following equation:
T e ＝T S +q
wherein, T e At a second temperature, TS isOutdoor ambient temperature, q is a fixed constant. For example, q may be set to [5,15 ]]Any one of the above numerical values. For example, 7, 10, 12, etc. may be provided.
It should be noted that the second temperature T is calculated e Less than 0, second temperature T e Set to a fixed value, such as 0 degrees celsius.
In the technical scheme that this embodiment is disclosed, when satisfying the stop preheating condition, control the air conditioner stops right the compressor preheats, owing to be provided with the stop preheating condition, consequently can avoid continuing to heat the compressor when the compressor need not to continue to heat, has reached like this when reducing the energy consumption of air conditioner, avoids leading to the effect that the phenomenon of compressor damage takes place because of the superheating.
Optionally, referring to fig. 4, based on any one of the above embodiments, in a further embodiment of the present invention, before step S10, the method further includes:
s50, determining a time interval required by the current time point to reach the starting time point;
in this embodiment, the timed power-on command may be sent to the air conditioner through a remote controller, a control panel and/or a mobile terminal.
When a timed starting-up instruction is sent to the air conditioner through the mobile terminal, the air conditioner can be provided with a networking module, so that the air conditioner can be involved in a local area network and/or a wide area network. And then communicate with the mobile terminal through a local area network and/or a wide area network. Therefore, the timing starting-up instruction sent by the mobile terminal is received.
When the timed starting-up instruction is obtained, the time interval when the current time point reaches the starting-up time point can be determined according to the timed starting-up instruction. When the time interval is less than or equal to a preset time interval, the step S10 is performed. Otherwise the air conditioner does not respond.
It should be noted that the preset time interval may be set to a fixed value. And may be set to a variable corresponding to the outdoor ambient temperature. When the variable corresponding to the outdoor ambient temperature is set, the outdoor ambient temperature may be acquired first, and then the preset time interval may be determined according to the outdoor ambient temperature. When the preset time interval is determined according to the outdoor environment temperature, a temperature interval where the outdoor environment temperature is located may be determined first, and then the preset time interval associated with the temperature interval is obtained.
It should be noted that the compressor of the air conditioner freezes more severely as the outdoor ambient temperature is lower. Therefore, the required warm-up time of the compressor is longer as the outdoor ambient temperature is lower, and thus the preset time interval can be made larger as the outdoor ambient temperature is smaller.
In the technical solution disclosed in this embodiment, a time interval between a current time point and a power-on time point is determined according to a timing power-on command, and then the step of obtaining the outdoor environment temperature and the operation parameters of the air conditioner is executed when the time interval is less than or equal to a preset time interval. The air conditioner is only preheated when the air conditioner is to be started, so that the phenomenon that the air conditioner is preheated when not used is avoided, the energy consumption of the air conditioner is increased, and the effect of reducing the energy consumption of the air conditioner is achieved.
Optionally, based on any one of the foregoing embodiments, in a further embodiment, the step S30 includes:
s31, when the exhaust temperature is judged to be lower than the first temperature and/or the shutdown duration is judged to be longer than the first duration, obtaining the heating power associated with the temperature interval where the outdoor environment temperature is located;
and S32, controlling the heating device to preheat the compressor according to the heating power.
In this embodiment, the air conditioner is provided with a heating device including a power adjusting part and a heating part. When it is determined that the exhaust temperature is less than the first temperature and/or the shutdown duration is longer than the first duration, a temperature interval where the outdoor environment temperature is located may be determined first, and then the heating power associated with the temperature interval may be obtained as the heating power of the heating device. And the power control component controls the heating component to heat the compressor with the heating power.
Specifically, when the heating member is a stator coil, the stator coil may be electrically connected to a power source, so that the stator coil may be charged by the power source. When current flows through the stator coils, the stator coils generate heat and transfer the heat through the rotor crankshaft into the oil sump of the compressor to heat the lubricating oil of the compressor.
Further, when the heating power is acquired, the current value of the current flowing into the stator coil can be calculated according to the heating power. And firstly, the current with the current value is led into the stator so as to lead the stator coil to heat.
In the technical scheme disclosed in this embodiment, the heating power associated with the temperature interval in which the outdoor environment temperature is located is obtained, and the heating device is controlled to preheat the compressor according to the heating power. Since the compressor is more severely frozen the lower the outdoor ambient temperature is, the compressor can be preheated with a larger heating power when the outdoor ambient temperature is lower. This achieves the effect of avoiding overheating of the compressor.
In addition, an embodiment of the present invention further provides an air conditioner, where the air conditioner includes a memory, a processor, and a control program of the air conditioner that is stored in the memory and is capable of running on the processor, and when the control program of the air conditioner is executed by the processor, the steps of the control method of the air conditioner according to the above embodiments are implemented.
