The air conditioner is in heating operation, when the temperature of the inner coil is higher than a certain temperature, such as 72 ℃, the compressor is stopped, then the temperature of the inner coil is reduced along with the operation of the inner fan, and when the temperature of the inner coil is lower than another temperature, such as 56 ℃, the starting condition of the compressor is reached. However, in the embodiment of the present disclosure, it is further necessary to determine whether the compressor can start up according to the temperature of the compressor, the shutdown frequency of the compressor, the ambient temperature, and so on? Therefore, the probability of continuous temperature rise of the compressor is reduced, the probability of failure reporting when the air conditioner compressor is stopped is reduced, and the stability and the efficiency of the air conditioner are improved.
Fig. 1 is a schematic flowchart of a control method for an air conditioner according to an embodiment of the present disclosure. As shown in fig. 1, the process for air conditioning control includes:
step 101: the current inner coil temperature of the air conditioner running in the heating mode is collected.
In the embodiment of the disclosure, the temperature of the inner coil of the air conditioner running in the heating mode is monitored, the temperature of the inner coil of the air conditioner running in the heating mode can be collected at regular time or in real time, and the collected temperature of the inner coil every time is the current temperature of the inner coil.
Step 102: and under the condition that the compressor of the air conditioner is stopped and the temperature of the current inner coil is less than or equal to a first set temperature, acquiring the current stop state information of the compressor.
In the process of heating operation of the air conditioner, the compressor may be in a shutdown state or a startup operation state, and after the compressor is shutdown, the compressor can be started only when the shutdown state information of the compressor meets certain conditions in order to prevent the compressor from being started up due to overhigh temperature and to cause failure alarm of the compressor.
When the front inside coil temperature is less than or equal to the first set temperature, for example: when the temperature of the current inner coil is less than or equal to 56 ℃, the starting conditions of a part of compressors are met, and at the moment, the current stop state information of the compressors needs to be acquired. The shutdown state information includes: the number of times of shutdown and the temperature of the compressor are needed, so that the current temperature of the compressor corresponding to the current temperature of the inner coil less than or equal to the first set temperature needs to be obtained, and it is also needed to know that the compressor in the shutdown state of the air conditioner is the shutdown for the first time in the heating operation process, that is, the number of times of shutdown of the compressor needs to be obtained.
Step 103: and controlling the compressor to start and operate under the condition that the current stop times in the current stop state information are more than 1 and the current compressor temperature in the current stop state information is less than the previous compressor temperature.
After the current shutdown times and the current compressor temperature in the current shutdown state information are determined, whether the set startup condition of the compressor is met or not can be judged in one step. If the current shutdown frequency is more than 1, namely the compressor is shutdown once, twice or more before the current shutdown, at this time, the temperature of the previous compressor corresponding to the temperature of the previous inner coil pipe which is less than or equal to the first set temperature during the previous shutdown can be obtained.
Comparing the current compressor temperature with the previous compressor temperature, if the current compressor temperature is lower than the previous compressor temperature, indicating that the compressor temperature is reduced, and continuing to raise the temperature to enable the probability that the compressor temperature is higher than the alarm temperature to be smaller, determining that the starting condition of the compressor is reached, and controlling the starting operation of the compressor.
Of course, if the current shutdown frequency is greater than 1, and the current compressor temperature in the current shutdown state information is greater than or equal to the previous compressor temperature, it indicates that the risk that the compressor continues to be heated to reach a temperature that is greater than the alarm temperature is high, and at this time, the compressor can continue to be in the shutdown state and continue to wait for the compressor to be cooled. However, in some embodiments, in order to ensure the heating effect of the heating operation of the air conditioner, the compressor start-up control may be further performed in combination with the ambient temperature of the air conditioning active area, that is, the current ambient temperature of the air conditioning active area is obtained when the current shutdown number is greater than 1 and the current compressor temperature is greater than or equal to the previous compressor temperature; and controlling the compressor to start and operate under the conditions that the current environment temperature is lower than the second set temperature and the current compressor temperature is lower than the third set temperature.
When the air conditioner is in heating operation, if the current ambient temperature is lower than a second set temperature, for example, the current ambient temperature is less than 18 ℃, the ambient temperature continues to decrease, which may cause bad experience to the user, and at this time, although the current compressor temperature is greater than or equal to the previous compressor temperature, if the current compressor temperature is lower than a third set temperature, for example: the compressor may also be controlled to start operation when the current compressor temperature is <90 ℃.
Certainly, if the current ambient temperature is less than the second set temperature and the current compressor temperature is greater than or equal to the third set temperature, the risk of the compressor high-temperature alarm is still greater if the compressor is started, so in some embodiments, the compressor temperature is continuously monitored until the compressor is cooled, and the compressor is controlled to start to operate when the obtained compressor temperature is less than the fourth set temperature, for example, the compressor temperature is less than 88 ℃. And when the current environment temperature is lower than the second set temperature and the current compressor temperature is higher than or equal to the third set temperature, continuously acquiring the compressor temperature until the compressor temperature is lower than the fourth set temperature, and controlling the compressor to start to operate. And the fourth set temperature is less than or equal to the third set temperature. For example: 88 ℃ <90 ℃. The fourth set temperature is lower than the third set temperature, so that the heat of the compressor can be dissipated for a plurality of times, and the damage risk of the compressor is reduced.
The air conditioner is in heating operation, if the current environment temperature is more than or equal to 22 ℃, the environment temperature is more appropriate, and if the current compressor temperature is more than or equal to the previous compressor temperature, the compressor can be still in a shutdown state and continuously cooled. And continuing to monitor the temperature of the compressor until the current environment temperature is lower than a second set temperature, and performing starting control according to the temperature of the compressor.
When the current inner coil temperature is less than or equal to the first set temperature, in the current shutdown state information of the obtained compressor, the current shutdown time is 1, which indicates that the compressor is in the first shutdown state, and the state information of the previous shutdown is not available, at the moment, the probability that the compressor reaches the alarm temperature is very low, and the compressor can be controlled to start. However, in order to reduce the temperature accumulation for the subsequent multiple shutdowns, in some embodiments, the starting control is also performed according to the current compressor temperature, that is, the compressor is controlled to start to operate under the condition that the current shutdown number is equal to 1 and the current compressor temperature is less than the third set temperature. For example: the current shutdown time is 1, and the current compressor temperature is less than 90 ℃, and the compressor can also be controlled to start running. Of course, when the current stop number is 1 and the current compressor temperature is greater than or equal to 90 ℃, the stop state of the compressor is continuously maintained.
During the heating operation of the air conditioner, once the detected current inner coil temperature is greater than or equal to the fifth set temperature, for example: when the temperature of the current inner coil pipe is larger than or equal to 72 ℃, the compressor needs to be controlled to stop, namely, the compressor of the air conditioner is started to operate, and the compressor is controlled to stop under the condition that the temperature of the current inner coil pipe is larger than or equal to a fifth set temperature. The fifth set temperature is greater than the first set temperature.
After the compressor is controlled to stop, namely the compressor is in a stop state, at the moment, the current compressor temperature in the current stop state information needs to be determined as the previous compressor temperature and stored; and adding 1 to the current shutdown frequency to obtain the updated current shutdown frequency. In this way, the previous shutdown state information can be obtained.
In the heating operation process of air conditioner, coil pipe temperature in detecting always, if when coil pipe temperature is less than the sixth settlement temperature in the current, fan operation in need of stopping, like this, prevent to blow cold wind, lead to the bad experience of user, consequently, under the condition that coil pipe temperature is less than the sixth settlement temperature in the current, fan stop operation in the control, the sixth settlement temperature is less than first settlement temperature.
In the above embodiment, the temperature of the inner coil is compared with a first set temperature, a fifth set temperature, and a sixth set temperature, wherein the fifth set temperature is greater than the first set temperature, and the first set temperature is greater than the sixth set temperature. For example: the fifth set point temperature may be 70 deg.C, 72 deg.C, or 75 deg.C, etc., the first set point temperature may be 55 deg.C, 56 deg.C, or 58 deg.C, etc., and the sixth set point temperature may be 35 deg.C, 36 deg.C, or 38 deg.C, etc. The third set temperature and the fourth set temperature can be respectively related to the compressor temperature, so the values are higher, for example: can be 85 ℃, 88 ℃, 90 ℃, or 92 ℃ and the like. And the second set temperature is related to the ambient temperature, which is a more comfortable temperature for the human body, for example: 18 ℃, 19 ℃, or 20 ℃ and the like. Specific values are not to be taken as an example and may relate to specific performance of each air conditioner.
Of course, after the air conditioner finishes the operation in the heating mode, the shutdown times of the compressor are cleared, and the stability and the continuity of the subsequent high-temperature protection control of the compressor are guaranteed.
Therefore, in the embodiment, after the compressor of the air conditioner operating in the heating mode is shut down, the compressor can be started only when the temperature of the inner coil reaches the starting condition and the temperature of the compressor is reduced to meet the set condition, so that the probability of continuous temperature rise of the compressor is reduced, the probability of failure reporting when the compressor of the air conditioner is shut down is reduced, and the stability and the efficiency of the air conditioner are improved.
The following operation flow is integrated into a specific embodiment to illustrate the air conditioning control process provided by the embodiment of the present invention.
In this embodiment, the respective set temperatures are stored, wherein the first set temperature is 56 ℃, the second set temperature is 18 ℃, the third set temperature is 90 ℃, the fourth set temperature is 88 ℃, the fifth set temperature is 72 ℃, and the sixth set temperature is 38 ℃.
