Example 1
The conventional external electric heating belt has low power, the heat loss is large when the temperature of the external ring is low, the effect of heating the oil temperature inside the compressor is poor after the oil is transferred to the compressor through the compressor cylinder, and the required time is long. The invention considers that the winding of the compressor is near the oil pool and even soaked in oil, the oil temperature is easier to heat through the winding heating, and the effect is much better than that of an external electric heating belt. Therefore, the invention controls the winding heating of the compressor through the control logic, does not need to continuously heat for a long time, and is more power-saving and safer.
Fig. 1 is a flowchart of a preheating control method of a compressor according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
and step S101, detecting the outdoor environment temperature after the air conditioner is powered on. In a specific implementation, a detection value of a temperature detection module (a temperature sensor, a temperature sensing bulb, or the like) provided on the outdoor unit may be used as the outdoor ambient temperature, and specifically, the temperature detection module may be provided at a return air inlet of the outdoor unit.
Step S102, judging a temperature interval of the outdoor environment temperature; in specific implementation, three temperature intervals can be set, and different temperature intervals correspond to different control logics.
And step S103, if the outdoor environment temperature is in the first temperature interval, controlling the winding of the compressor to heat.
Step S104, if the outdoor environment temperature is in a second temperature interval, controlling the winding of the compressor to heat under the condition that the outdoor environment temperature is detected for the first time after the air conditioner is powered on; and maintaining the previous control logic under the condition that the outdoor environment temperature is not detected for the first time after the air conditioner is powered on.
Step S105, if the outdoor ambient temperature is in the third temperature interval, the winding heating of the compressor does not need to be controlled.
The embodiment provides a preheating control logic under power-on state of compressor low temperature, for the oil bath hydrops of avoiding the compressor, controls the winding heating according to outdoor ambient temperature's size through control logic, can evaporate the refrigerant in the oil bath fast, promotes the compressor and preheats efficiency, can control power consumption again, does not last the purpose that the heating realized energy-conserving power saving.
After the compressor is powered on, corresponding control logic (controlling the winding heating of the compressor or not needing to control the winding heating of the compressor) is executed according to the temperature interval where the outdoor environment temperature is located, and the risk of starting with liquid does not exist if the compressor is started at the moment, but the compressor is not immediately started to operate. Whether the compressor is started or not depends on whether a starting instruction of a user is received or not and whether a starting condition is met currently or not, the starting condition is determined based on the indoor environment temperature and the set temperature, for example, the starting condition can be set to be that the difference value between the indoor environment temperature and the set temperature exceeds a preset difference value, or the difference value between the indoor environment temperature and the set temperature exceeds the preset difference value and is maintained for a period of time, and the like. And directly controlling the compressor to start up and run after receiving a starting-up instruction of a user and determining that the indoor environment where the air conditioner is located meets the starting-up condition. Based on this, can avoid the compressor not have the risk of taking the liquid to start under the prerequisite, confirm the start opportunity of compressor, guarantee that the compressor can normally start.
After the air conditioner is powered on, the outdoor environment temperature is detected for no more than one time, and after corresponding control logic is executed when the outdoor environment temperature is in a first temperature region, a second temperature region or a third temperature region, the stop time of the compressor is timed; and if the shutdown time of the compressor exceeds the preset time, detecting the outdoor environment temperature again, and executing a new round of control logic. It is emphasized that if the outdoor ambient temperature is detected for the first time to be in the second temperature interval, the control logic to be executed is: and controlling the winding heating of the compressor, and then, if the outdoor environment temperature is detected to be in the second temperature interval, referring to and maintaining the previous control logic. If the outdoor environment temperature is detected not to be in the second temperature interval for the first time, after that, if the outdoor environment temperature is detected to be in the second temperature interval, the control logic of the previous time is referred to and maintained. Specifically, it is necessary to acquire a control logic executed after the outdoor ambient temperature is detected for the previous time; wherein the control logic comprises: controlling the heating of the windings of the compressor or not controlling the heating of the windings of the compressor; and then executes the same control logic as the previous control logic.
Based on the above preferred embodiment, a transition option is provided, i.e. if the outdoor environment temperature changes, the section where it is located also changes, and the control logic does not necessarily need to be adjusted. If the outdoor environment temperature detected last time is in a first temperature interval, the air temperature is low at the moment, a refrigerant exists in the compressor at a high probability, the winding of the compressor needs to be controlled for heating, if the compressor is not started after heating is finished, and after the shutdown time of the compressor exceeds the preset time, if the air temperature is increased at the moment, the outdoor environment temperature detected again is in a second temperature interval, then the air temperature is increased from low temperature during the shutdown period of the compressor, and the refrigerant possibly exists in the compressor at the moment, the former control logic is maintained, namely the winding of the compressor is controlled for heating. The present embodiment sets the above transition selection, which is not only to determine the corresponding control logic according to the value of the currently detected outdoor environment temperature, but more importantly to select whether to adjust the control logic based on the change (temperature increase, temperature decrease) of the outdoor environment temperature. The winding of the compressor is prevented from being heated frequently along with the change of the air temperature.
That is, the present invention is focused not only on how to determine the preheating control logic of the compressor and the winding heating time period according to the outdoor ambient temperature, but also on the adjustment of the preheating control logic of the compressor as the outdoor ambient temperature changes.
If the outdoor environment temperature detected last time is in the third temperature interval, the air temperature is higher at the moment, the winding heating of the compressor is not required to be controlled, if the compressor is not started, after the shutdown time of the compressor exceeds the preset time, the air temperature is reduced at the moment, the outdoor environment temperature detected again is in the second temperature interval, the possibility that the refrigerant exists in the compressor is not great at the moment when the air temperature is reduced from the high temperature during the shutdown time of the compressor is considered, and therefore the former control logic is maintained, namely the winding heating of the compressor is not required to be controlled.
Based on this, if the user does not use the air conditioner for a long time, the control logic according to the embodiment may heat the compressor in stages (for example, the preset time period for the compressor to stop may be set to 5h) along with the change of the outdoor environment temperature, for example, in the climate condition with a large temperature difference between the morning and the evening. And when the temperature is lower at night, the winding of the compressor is controlled to be heated if the outdoor environment temperature is in a first temperature interval, and when the temperature is higher at noon, the winding of the compressor is not required to be heated if the outdoor environment temperature is in a third temperature interval. Therefore, the preheating program of the compressor is not continuously heated but is controlled in stages along with the change of the outdoor environment temperature, so that the purposes of saving energy and electricity can be achieved while the preheating efficiency of the compressor is improved.
Considering that the compressor needs to be preheated only when the outdoor environment temperature is low, and the compressor does not need to be preheated when the outdoor environment temperature is high, therefore, the first temperature interval in this embodiment is: the outdoor environment temperature is less than a first temperature value; the second temperature interval is as follows: the first temperature value is less than or equal to the outdoor environment temperature and less than or equal to the second temperature value; the third temperature interval is: the outdoor environment temperature is larger than the second temperature value. In a specific application, the first temperature value may be set to be 5 ℃ and the second temperature value may be set to be 10 ℃.
On the basis of adjusting the preheating control logic of the compressor according to the outdoor environment temperature, in order to further guarantee the heating effect and avoid the situation that the power consumption is higher due to overlong heating time, the heating time of the winding heating can be controlled according to the outdoor environment temperature.
Specifically, if the outdoor environment temperature is in a first temperature interval, determining the corresponding heating time length according to the outdoor environment temperature; and controlling the winding heating of the compressor according to the heating time length. When the corresponding heating time length is determined according to the outdoor environment temperature, a first temperature partition where the outdoor environment temperature is located can be determined, and the corresponding heating time length is determined according to the first temperature partition; at least one first temperature partition divided according to the first temperature interval is preset, and the heating time corresponding to each first temperature partition is preset. The one-to-one correspondence relationship between the outdoor ambient temperature and the heating time period, the negative correlation relationship between the outdoor ambient temperature and the heating time period, and the like can also be preset. In any way, the appropriate heating time duration can be determined according to the outdoor environment temperature, and the lower the outdoor environment temperature is, the longer the heating time duration is.
Similarly, if the outdoor environment temperature is in the second temperature interval, under the condition that the outdoor environment temperature is detected for the first time after the air conditioner is powered on, the corresponding heating time length is determined according to the outdoor environment temperature detected for the first time, and the winding of the compressor is controlled to be heated according to the heating time length. When the corresponding heating time length is determined according to the outdoor environment temperature detected for the first time, determining a second temperature subarea where the outdoor environment temperature detected for the first time is located, and determining the corresponding heating time length according to the second temperature subarea; at least one second temperature partition divided according to a second temperature interval is preset, and the heating time corresponding to each second temperature partition is preset. The one-to-one correspondence relationship between the outdoor ambient temperature and the heating time period, the negative correlation relationship between the outdoor ambient temperature and the heating time period, and the like can also be preset. In any way, the appropriate heating time duration can be determined according to the outdoor environment temperature, and the lower the outdoor environment temperature is, the longer the heating time duration is.
Table 1 shows a correspondence relationship between the first temperature zones and the heating time periods, where n denotes that the first temperature section is divided into n first temperature zones, and n is a natural number.

The lower the outdoor ambient temperature, the longer the winding heating period. For example, when the outdoor environment temperature is-20 ℃, the winding heating time is 8 minutes; when the outdoor environment temperature is 0 ℃, the winding is heated for 4 minutes; when the outdoor ambient temperature is 5 ℃, the winding is heated for 3 minutes.

Likewise, a similar approach is taken for dividing the second temperature interval into m second temperature zones, as in table 1. Table 2 shows the correspondence relationship between the second temperature zones and the heating time periods, and m represents the division of the second temperature zone into m second temperature zones. m is a natural number.

The control logic for preheating the compressor after the air conditioner is powered on is introduced, and the control logic can be applied to the standby state of the air conditioner, so that the refrigerant in the oil pool can be quickly evaporated, the preheating efficiency of the compressor is improved, the power consumption can be controlled, and the aims of saving energy and electricity are fulfilled without continuous heating. The control logic in the standby state of the air conditioner will be described below.
Detecting the outdoor environment temperature and judging the temperature interval of the outdoor environment temperature in the standby state of the air conditioner; in specific implementation, three temperature intervals can be set, and different temperature intervals correspond to different control logics; if the outdoor environment temperature is in a first temperature interval, controlling the winding of the compressor to heat; if the outdoor environment temperature is in the second temperature interval, controlling the winding of the compressor to heat under the condition that the outdoor environment temperature is detected for the first time in the standby state of the air conditioner; when the outdoor environment temperature is not detected for the first time in the standby state of the air conditioner, maintaining the previous control logic; if the outdoor ambient temperature is in the third temperature interval, the winding heating of the compressor does not need to be controlled.
It should be noted that the three temperature intervals set in the standby state of the air conditioner and the three temperature intervals set in the power-on state of the air conditioner may be the same temperature intervals, or may be slightly adjusted. If the control logic is used in a set of air conditioning units, the same temperature interval division is generally adopted even if the operation states are different.
When the air conditioner is just in a standby state, the air conditioner is generally not started again immediately, so that the shutdown time of the compressor can be selected to be timed firstly, and the outdoor environment temperature is triggered and detected after the shutdown time of the compressor exceeds the preset time. Of course, it is also possible to select to directly detect the outdoor ambient temperature after the air conditioner enters the standby state, and execute the corresponding control logic. Can be selected and adjusted according to the use habits of users.
In the standby state of the air conditioner, the detection of the outdoor environment temperature is not limited to one time, and after corresponding control logic is executed according to the outdoor environment temperature in a first temperature region, a second temperature region or a third temperature region, the stop time of the compressor is timed; and if the shutdown time of the compressor exceeds the preset time, detecting the outdoor environment temperature again. The outdoor environment temperature is detected in stages and corresponding control logic is executed, the condition that a refrigerant can be transferred to the compressor when the air conditioner is placed in a standby mode for a long time under the low-temperature working condition is avoided, and the compressor cannot run with liquid any time a user selects to start the air conditioner.
In the standby state of the air conditioner, the heating time period for the winding heating of the compressor is also dependent on the outdoor ambient temperature. Specifically, if the outdoor ambient temperature is in a first temperature interval, controlling the winding heating of the compressor comprises: determining corresponding heating time according to the outdoor environment temperature; and controlling the winding heating of the compressor according to the heating time length. Specifically, a first temperature partition in which the outdoor environment temperature is located is determined; determining corresponding heating time according to the first temperature partition; at least one first temperature partition divided according to the first temperature interval is preset, and the heating time corresponding to each first temperature partition is preset. The one-to-one correspondence relationship between the outdoor ambient temperature and the heating time period, the negative correlation relationship between the outdoor ambient temperature and the heating time period, and the like can also be preset. In any way, the appropriate heating time duration can be determined according to the outdoor environment temperature, and the lower the outdoor environment temperature is, the longer the heating time duration is.
If the outdoor environment temperature is in the second temperature interval, the winding of the compressor is controlled to be heated under the condition that the outdoor environment temperature is detected for the first time after the air conditioner is powered on, and the method is realized by the following preferred embodiment: determining corresponding heating time according to the outdoor environment temperature detected for the first time; and controlling the winding heating of the compressor according to the heating time length. Specifically, a second temperature partition where the outdoor environment temperature detected for the first time is located is determined; determining corresponding heating time according to the second temperature partition; at least one second temperature partition divided according to a second temperature interval is preset, and the heating time corresponding to each second temperature partition is preset. Based on this, the control logic under the above-mentioned air conditioner standby state controls the winding heating according to the size of outdoor ambient temperature, can evaporate the refrigerant in the oil bath fast, promotes the compressor and preheats efficiency, can control power consumption again, does not continuously heat the purpose that realizes energy-conserving power saving.
It is emphasized that, if the outdoor environment temperature is in the second temperature interval, in the case that the outdoor environment temperature is not detected for the first time in the standby state of the air conditioner, the control logic executed after the outdoor environment temperature is detected for the previous time is obtained; wherein the control logic comprises: controlling the heating of the windings of the compressor or not controlling the heating of the windings of the compressor; the same control logic as described above is then executed. Based on the above preferred embodiment, a transition option is provided, i.e. if the outdoor environment temperature changes, the section where it is located also changes, and the control logic does not necessarily need to be adjusted. The present embodiment sets the above transition selection, which is not only to determine the corresponding control logic according to the value of the currently detected outdoor environment temperature, but more importantly to select whether to adjust the control logic based on the change (temperature increase, temperature decrease) of the outdoor environment temperature. The winding of the compressor is prevented from being heated frequently along with the change of the air temperature.
During the heating of the winding of the compressor, in order to ensure the service life and safety of the controller of the air conditioner, the temperature of a driving module in the controller of the air conditioner needs to be detected, and when the temperature of the driving module exceeds a preset threshold value, the heating of the winding of the compressor is stopped. Thereby guaranteeing the use safety of the controller in the preheating stage of the compressor. The temperature of the driving module is detected through a temperature sensing bulb arranged on the driving module.

In specific application, the time for stopping the compressor is timed considering that the refrigerant does not flow into the compressor immediately when the air conditioner is just in a standby state; and triggering and detecting the outdoor environment temperature after the shutdown time of the compressor exceeds the preset time.
Step S302, judging a temperature interval of the outdoor environment temperature; in specific implementation, three temperature intervals can be set, and different temperature intervals correspond to different control logics.

In the standby state of the compressor, after corresponding control logic (controlling the winding heating of the compressor or not needing to control the winding heating of the compressor) is executed according to the temperature interval where the outdoor environment temperature is located, the risk of starting with liquid does not exist if the compressor is started at the moment, but the compressor is not immediately started to operate at the moment. Whether the compressor is started or not depends on whether a starting instruction of a user is received or not and whether a starting condition is met currently or not, the starting condition is determined based on the indoor environment temperature and the set temperature, for example, the starting condition can be set to be that the difference value between the indoor environment temperature and the set temperature exceeds a preset difference value, or the difference value between the indoor environment temperature and the set temperature exceeds the preset difference value and is maintained for a period of time, and the like. And directly controlling the compressor to start up and run after receiving a starting-up instruction of a user and determining that the indoor environment where the air conditioner is located meets the starting-up condition. Based on this, can avoid the compressor not have the risk of taking the liquid to start under the prerequisite, confirm the start opportunity of compressor, guarantee that the compressor can normally start.
In the standby state of the air conditioner, the detection of the outdoor environment temperature is not limited to one time, and the shutdown time length of the compressor is timed after corresponding control logic is executed when the outdoor environment temperature is in a first temperature zone or a second temperature zone or a third temperature zone; and if the shutdown time of the compressor exceeds the preset time, detecting the outdoor environment temperature again, and executing a new round of control logic.
It is emphasized that if the outdoor ambient temperature is detected for the first time to be in the second temperature interval, the control logic to be executed is: and controlling the winding heating of the compressor, and then, if the outdoor environment temperature is detected to be in the second temperature interval, referring to and maintaining the previous control logic. If the outdoor environment temperature is detected not to be in the second temperature interval for the first time, after that, if the outdoor environment temperature is detected to be in the second temperature interval, the control logic of the previous time is referred to and maintained. Specifically, it is necessary to acquire a control logic executed after the outdoor ambient temperature is detected for the previous time; wherein the control logic comprises: controlling the heating of the windings of the compressor or not controlling the heating of the windings of the compressor; and then executes the same control logic as the previous control logic.
