Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the present invention and should not be construed as limiting the present application.
An air conditioner and a control method and apparatus thereof according to an embodiment of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a method for controlling an air conditioner according to an embodiment of the present disclosure. As shown in fig. 1, the method for controlling an air conditioner according to the embodiment of the present application specifically includes the following steps:
s101, acquiring a preset temperature reaching shutdown temperature in a room.
Generally, when the indoor temperature reaches the temperature set by the user, the air conditioner will stop operating, and therefore, in this embodiment, the temperature set by the user on the air conditioner is referred to as the temperature-reached shutdown temperature. When the temperature reaching shutdown temperature is obtained, the temperature reaching shutdown temperature can be determined according to a temperature adjusting instruction issued by a user last time. For example, the temperature is set to 20 ℃ before the temperature adjustment, and at this time, the user issues a temperature adjustment instruction to decrease the temperature by 2 ℃, so that the temperature reaching shutdown temperature at this time can be determined to be 18 ℃.
S102, acquiring a target temperature of the air conditioner according to the temperature reaching shutdown temperature; wherein the target temperature is less than the warm-up shutdown temperature.
Specifically, the temperature-to-temperature shutdown temperature is acquired, and the target temperature of the air conditioner can be acquired according to the temperature-to-temperature shutdown temperature. In this embodiment, the target temperature is lower than the temperature-controlled shutdown temperature.
Alternatively, the target temperature may be determined according to a compensation factor for the warm-up shutdown temperature. As shown in fig. 2, the method comprises the following steps:
s201, acquiring a temperature compensation coefficient aiming at the temperature-reaching shutdown temperature.
Specifically, a temperature compensation coefficient for the temperature reaching shutdown temperature may be pre-stored in the air conditioner, and when the temperature compensation coefficient needs to be acquired, the pre-stored parameter is queried, so that the temperature compensation coefficient may be acquired.
In addition, in order to improve the control accuracy, the temperature compensation coefficient can be determined according to the current indoor temperature. For example, by using the indoor temperature to look up a preset mapping table between the indoor temperature and the temperature compensation coefficient, the temperature compensation coefficient corresponding to the current indoor temperature can be determined.
S202, determining a target temperature according to the temperature compensation coefficient and the temperature-reaching shutdown temperature.
Specifically, determining the temperature compensation coefficient allows the target temperature to be determined based on the temperature compensation coefficient and the temperature-up shutdown temperature. For example, the target temperature may be a multiplication between a temperature compensation coefficient and a temperature-reaching shutdown temperature, where the value range of the temperature compensation coefficient is (0, 1); alternatively, the target temperature may be a difference between the temperature-reaching shutdown temperature and the temperature compensation coefficient, and the like, which may be determined according to actual conditions and is not limited herein.
S103, acquiring the current indoor temperature.
Generally, the current indoor temperature in the room may be acquired by a temperature sensor provided in the room.
And S104, recognizing that the indoor temperature reaches the target temperature, and controlling a compressor in the air conditioner to run at the minimum running frequency.
Specifically, when the indoor temperature is identified to reach the target temperature, the compressor in the air conditioner is controlled to run at the minimum running frequency, so that the indoor temperature can slowly reach the temperature of the temperature stop, sufficient time can be provided for heat exchange between different indoor areas, the temperatures of the different areas can be uniformly changed, the situation that the compressor is frequently started and stopped due to the fact that the difference between the temperatures of the different areas is large when the compressor is stopped is avoided, and the reliability of the compressor is improved. In addition, because the compressor restarts the back, reaches again and predetermines the frequency and need certain time, indoor temperature has influenced indoor environment's comfort level because of uncontrolled production great temperature fluctuation in this period of time, and has reduced the compressor in this embodiment and has stopped the frequency of opening, consequently, it has also avoided the great condition of indoor temperature fluctuation, has promoted indoor environment's comfort level.
In some embodiments, during the operation of the air conditioner, the operation frequency of the compressor may be monitored, and the opening degree of the electronic expansion valve in the air conditioner may be adjusted according to the operation frequency of the compressor, so as to control the flow rate of refrigerant in the air conditioner, and further control the indoor temperature. As shown in fig. 3, the method comprises the following steps:
s301, obtaining the running frequency of the compressor.
Generally, a frequency sensor may be utilized to acquire the operating frequency of the compressor.
S302, identifying that the operation frequency is the minimum operation frequency, and adjusting the opening of an electronic expansion valve in the air conditioner to the maximum opening.
Specifically, after the operating frequency of the compressor is acquired, the operating frequency is compared with the minimum operating frequency of the compressor. And if the operating frequency of the compressor is equal to the minimum operating frequency, adjusting the opening of the electronic expansion valve to the maximum opening to avoid throttling the refrigerant in the air conditioner. When the opening of the electronic expansion valve is the maximum opening, the pressures of the refrigerants at the two ends of the electronic expansion valve are close, so that the air conditioner can hardly output cold (or heat), and the indoor temperature can not generate large fluctuation under the action of the air conditioner; at the moment, sufficient time can be provided for heat exchange between different areas in the compressor stopping front chamber, so that the temperatures of the different areas can be uniformly changed, and the condition that the compressor is frequently started and stopped due to the fact that the difference between the temperatures of the different areas is large when the compressor is stopped is avoided.
Furthermore, after the opening degree of the electronic expansion valve is adjusted to the maximum opening degree, the indoor temperature can be continuously monitored, and when the indoor temperature reaches the temperature shutdown temperature, the compressor is controlled to be shut down, so that the energy waste phenomenon caused by continuous operation of the compressor is avoided. As shown in fig. 4, the method comprises the following steps:
s401, continuously acquiring the indoor temperature.
Generally, the current indoor temperature in the room may continue to be acquired using the temperature sensor provided in the room.
S402, recognizing that the indoor temperature reaches the temperature of shutdown, and controlling the compressor to stop working.
Specifically, when the acquired indoor temperature is identified to be equal to the temperature-reached shutdown temperature, the compressor is controlled to stop working.
Further, before the compressor is controlled to stop, the time length of the electronic expansion valve running at the maximum opening degree can be monitored to ensure that the air conditioner can stably run. Specifically, when the opening degree of the electronic expansion valve is adjusted to the maximum opening degree, a timer may be used to start recording the time length of the electronic expansion valve operating at the maximum opening degree, and when the time length of the electronic expansion valve operating at the maximum opening degree reaches a first preset time length, the air conditioner is already in a stable operation state, and at this time, the compressor may be controlled to stop. In addition, because the temperatures of different indoor areas need a certain time when reaching the equilibrium, therefore, after the electronic expansion valve runs for a certain time with the maximum opening, the indoor different areas can be ensured to have sufficient time for heat exchange before the compressor is stopped, so that the temperatures of different areas can be uniformly changed, and the condition that the compressor is frequently started and stopped due to the large difference between the temperatures of different areas when the compressor is stopped is avoided.
In some embodiments, before the compressor is controlled to stop, when the indoor temperature reaches the temperature stop temperature, the compressor is controlled to operate continuously for a period of time to ensure that the temperatures of different areas in the indoor space reach equilibrium. Specifically, when the indoor temperature is detected to reach the warm shutdown temperature, a timer can be used for starting to record the time length when the indoor temperature reaches the warm shutdown temperature, when the time length when the indoor temperature reaches the warm shutdown temperature reaches a second preset time length, the temperatures of different indoor areas reach equilibrium, and at this time, the compressor is controlled to be shut down.
To sum up, the technical solution in the embodiment of the present application at least has the following technical effects or advantages:
1. before the indoor temperature reaches the temperature shutdown temperature, the compressor in the air conditioner is controlled to run at the minimum frequency, so that the indoor temperature can slowly reach the temperature shutdown temperature, sufficient time can be provided for heat exchange between different indoor areas, the temperatures of the different areas can be uniformly changed, and the condition that the compressor is frequently started and stopped due to the fact that the difference between the temperatures of the different areas is large when the compressor is shut down is avoided.
2. When the compressor runs at the minimum running frequency, the opening degree of the electronic expansion valve is adjusted to the maximum opening degree, so that the pressures of refrigerants at two ends of the electronic expansion valve are similar, and the output cold quantity (or heat quantity) of the air conditioner is reduced to the minimum; further, the temperature in the room does not fluctuate greatly under the action of the air conditioner, and sufficient time is provided for heat exchange between different areas in the room.
3. After the electronic expansion valve operates for a period of time at the maximum opening degree, the compressor is controlled to stop, and the stable operation of the air conditioner is ensured.
4. After the indoor temperature reaches the warm shutdown temperature, the compressor is continuously controlled to operate for a period of time, so that sufficient time is provided for heat exchange between different indoor areas.
