The invention provides a control method of an air conditioner.
In an embodiment of the present invention, as shown in fig. 1, the air conditioner includes:
the compressor 11 assembly 10, the compressor 11 assembly 10 includes a compressor 11 and a liquid storage tank 12, and the air inlet of the compressor 11 is communicated with the air outlet of the liquid storage tank 12;
a throttle member 20 provided at an air return port of the liquid storage tank 12;
and the heat exchanger is communicated with the exhaust port of the compressor 11.
The control method of the air conditioner comprises the following steps:
s1: acquiring a first indoor temperature;
s2: the opening degree level of the throttling part 20 is adjusted according to the first indoor temperature to adjust the discharge pressure of the compressor 11.
In this embodiment, the heat exchanger includes an indoor heat exchanger and an outdoor heat exchanger, the exhaust port of the compressor 11 and the return air port of the liquid storage tank 12 are communicated with the indoor heat exchanger and the outdoor heat exchanger through a four-way valve, and the four-way valve is used for realizing switching communication between the compressor 11 and the liquid storage tank 12 and the indoor heat exchanger and the outdoor heat exchanger, thereby realizing switching between a cooling mode and a heating mode of the air conditioner. For example, in a refrigeration mode of the air conditioner, a refrigerant is compressed by the compressor 11 and converted into a high-temperature and high-pressure gas, the gas enters the outdoor heat exchanger through the four-way valve to absorb and release heat, then is converted into a low-temperature and low-pressure liquid state, enters the indoor heat exchanger to absorb and release heat, and then is converted into a low-temperature and low-pressure gas, and flows back to the liquid storage tank 12 through the four-way valve, so that the refrigeration cycle of the refrigerant is realized. The receiver 12 is used for separating gaseous refrigerant and liquid refrigerant, so that the compressor 11 can normally suck gaseous refrigerant for compression and transportation.
The throttling part 20 can be a throttling electromagnetic valve, so that a user can remotely or automatically control the throttling part 20, and the air passing area of the throttling part 20 can be changed by adjusting the opening of the throttling part 20 to change the air passing amount of the throttling part 20, so that the exhaust pressure of the compressor 11 can be changed, and the energy consumption and the running noise of the compressor 11 can be changed. For example, in a cooling mode of the air conditioner, a user can adjust the opening degree of the throttling component 20 according to the indoor temperature, when the indoor temperature is reduced to the temperature meeting the user requirement, the opening degree of the throttling component 20 can be adjusted to be small, the amount of the refrigerant entering the liquid storage tank 12 is reduced at the moment, so that the amount of the refrigerant sucked by the compressor 11 is also reduced, the exhaust pressure of the compressor 11 is reduced, and therefore, the energy consumption of the compressor 11 is reduced, the vibration is weakened, and the noise is correspondingly reduced.
The air conditioner further includes a temperature sensor for sensing an indoor temperature, and a controller for controlling an opening degree of the throttling part 20 according to a sensing signal of the temperature sensor to control a discharge pressure of the compressor 11.
Specifically, in an embodiment, the step S2 includes:
s21: acquiring an operation mode of the air conditioner, if the air conditioner is in a cooling mode, executing step S22, and if the air conditioner is in a heating mode, executing step S23;
s22: comparing the first indoor temperature with a first preset temperature, and if the first indoor temperature is greater than the first preset temperature, executing step S221; if the first indoor temperature is less than or equal to the first preset temperature, performing step S222;
s221: increasing the opening degree of the throttling part 20;
s222: reducing the opening degree of the throttling part 20;
s23: comparing the first indoor temperature with a second preset temperature, and if the first indoor temperature is lower than the second preset temperature, executing the step 221; if the first indoor temperature is greater than or equal to the second preset temperature, the step S222 is executed.
In this embodiment, the temperature sensor monitors the room temperature in real time, and transmits the monitoring signal to the controller, and the controller determines whether to adjust the opening degree of the throttling element 20 by comparing the first indoor temperature with a first preset temperature, where the first preset temperature may be a target temperature required by the user. Before the opening degree of the throttle member 20 is adjusted according to the indoor temperature, the operation mode of the air conditioner needs to be determined; for example, in a cooling mode of the air conditioner, if the first indoor temperature is less than or equal to a first preset temperature, the opening degree of the throttling element 20 is decreased, and if the first indoor temperature is greater than the first preset temperature, the opening degree of the throttling element 20 is increased; in the heating mode of the air conditioner, if the first indoor temperature is greater than or equal to a first preset temperature, the opening degree of the throttling part 20 is reduced, and if the first indoor temperature is less than the first preset temperature, the opening degree of the throttling part 20 is increased; it should be noted that the preset temperature in the cooling mode and the preset temperature in the heating mode may be the same or different, and are not limited herein. Thereby, an accurate control of the throttling part 20 according to the indoor temperature is achieved in different operation modes of the air conditioner, so that the adjustment of the discharge pressure of the compressor 11 can be achieved in different operation modes of the air conditioner. When the indoor temperature reaches the preset temperature, the exhaust pressure of the compressor 11 is properly reduced, so that the change of the indoor temperature is not influenced, and the energy consumption and vibration of the compressor 11 can be effectively reduced, thereby reducing the running noise of the compressor 11 and improving the overall performance of the air conditioner.
The air conditioner of the invention is provided with the throttle part 20 at the air return port of the liquid storage tank 12, and the air conditioner can adjust the opening degree of the throttle part 20 according to the parameters such as the operating condition of the compressor 11, the indoor temperature and the like through the control method of the air conditioner, thereby changing the exhaust pressure of the compressor 11, effectively reducing the exhaust pressure of the compressor 11 on the premise that the indoor temperature meets the requirement of a user, reducing the energy consumption and the operating noise of the compressor 11 and improving the overall performance of the air conditioner.
Further, as shown in fig. 2, before the step S1, steps S01 and S02 are further included;
s01: acquiring a first operation time period of the compressor 11, and comparing the first operation time period with a first preset time period;
s02: if the first operation duration is greater than or equal to the first preset duration, executing the steps S1 and S2.
In this embodiment, the air conditioner further includes a timing sensor for recording an operation duration of the compressor 11, the timing sensor sends a real-time operation duration signal of the compressor 11 to the controller, the controller compares the first operation duration with a first preset duration, and then determines whether to execute steps S1 and S2 according to the comparison result; that is, if the first operation period is greater than or equal to the first preset period, the controller controls the opening of the regulating valve according to the indoor temperature.
In another embodiment, as shown in fig. 2, the step S01 is followed by a step S03: if the first operation duration is less than the first preset duration, executing steps S3 and S4;
s3: acquiring a second indoor temperature and a preset displacement of the compressor 11;
s4: and adjusting the opening degree of the throttling component 20 according to the ratio of the second indoor temperature to the preset displacement.
In the present embodiment, the displacement of the compressor 11 refers to the volume of the refrigerant sucked into or discharged from the compressor 11 per cooling or heating cycle. The controller controls the opening degree of the throttle member 20 by comparing a first ratio of the second indoor temperature and the preset displacement with a preset ratio. It should be noted that the operation mode of the air conditioner needs to be acquired before the opening degree of the throttle member 20 is controlled according to the first ratio. For example, in a cooling mode of the air conditioner, if the first ratio is greater than a preset ratio, the opening degree of the throttling part 20 is increased, and if the first ratio is less than or equal to the preset ratio, the opening degree of the throttling part 20 is decreased; if the first ratio is smaller than the preset ratio, the opening degree of the throttle 20 is decreased. In the heating mode of the air conditioner, if the first ratio is smaller than the preset ratio, the opening degree of the throttling part 20 is increased; if the first ratio is greater than or equal to the preset ratio, the opening degree of the throttle 20 is decreased. It should be noted that the preset ratio of the cooling mode and the preset ratio of the heating mode may be the same or different, and are not limited herein. In practical applications, the displacement of the same compressor 11 is fixed, and therefore the control condition for the opening degree of the throttling part 20 for the same air conditioner is mainly dependent on the indoor temperature.
Further, as shown in fig. 3, the step S2 includes:
s24: acquiring a preset opening degree of the throttling component 20 according to the first indoor temperature;
s25: and adjusting the throttling part 20 to the preset opening degree.
In this embodiment, the preset opening degree of the throttling element 20 may form a mapping relation with the preset temperature, for example, each preset temperature corresponds to a preset opening degree, if the first indoor temperature is the same as one of the preset temperatures, the corresponding preset opening degree of the throttling element 20 is obtained, and the throttling element 20 is adjusted to the preset opening degree, so that the control condition and the control result of the throttling element 20 can be more accurate.
Further, as shown in fig. 4, the step S24 includes:
s241: comparing the first indoor temperature with a third preset temperature and a fourth preset temperature, and if the first indoor temperature is greater than or equal to the third preset temperature and less than the fourth preset temperature, executing step S242;
s242: and acquiring a first preset opening degree of the throttling part 20, wherein the first preset opening degree and the maximum opening degree of the throttling part 20 form a first preset ratio.
In this embodiment, a first preset temperature zone is formed between the third preset temperature and the fourth preset temperature, the first preset temperature zone forms a mapping relationship with the first preset opening, if the first indoor temperature is located in the first preset temperature zone, the controller obtains the first preset opening of the throttling component 20 according to the mapping relationship, the first preset opening and the maximum opening of the throttling component 20 form a first preset ratio, and finally the controller adjusts the throttling component 20 to the obtained first preset opening to complete the opening control of the throttling component 20. Therefore, the opening degree of the throttling component 20 can be kept unchanged in a certain temperature interval, the air return process of the compressor 11 is more stable, and the stability of the exhaust pressure of the compressor 11 is improved on the basis of effectively adjusting the exhaust pressure of the compressor 11, so that the service life of the compressor 11 is prolonged, and the stability of the air conditioner is improved.
In practical application, the third preset temperature is 16.5-17.5 ℃, and the fourth preset temperature is 20.5-21.5 ℃. If the third preset temperature is lower than 16.5 ℃, the preset temperature zone will become large, so that the throttle component 20 cannot adjust the opening degree in time according to the change of the temperature zone; if the third preset temperature is higher than 17.5 ℃, the opening of the throttling element 20 may be changed too fast, so that the discharge pressure of the compressor 11 may be changed too fast, which is not favorable for the service life of the compressor 11. Therefore, the third preset temperature is set to 16.5 ℃ to 17.5 ℃, so that the throttle member 20 can adjust the opening degree according to the temperature change in time, the exhaust pressure of the compressor 11 can be adjusted, and the stability of the whole air conditioner can be improved. The first preset ratio is 0.9 to 1, and the first temperature zone belongs to a lower temperature zone, at this time, the compressor 11 needs enough refrigerant exhaust pressure to keep the indoor temperature in the temperature zone, so the opening degree of the throttling component 20 in the temperature zone should be increased as much as possible to increase the exhaust pressure of the compressor 11 and ensure the temperature regulation function of the air conditioner. If the first predetermined ratio is less than 0.9, the discharge pressure of the compressor 11 cannot meet the discharge pressure requirement for maintaining the temperature interval, and therefore, setting the first predetermined ratio to 0.9 to 1 can effectively reduce the discharge pressure of the compressor 11 and reduce the energy consumption and the operation noise of the compressor 11 on the basis of ensuring the temperature regulation function of the compressor 11.
Further, the step S24 further includes:
s243: comparing the first indoor temperature with the fourth preset temperature and a fifth preset temperature, and if the first indoor temperature is greater than or equal to the fourth preset temperature and less than the fifth preset temperature, performing step S244;
s244: acquiring a second preset opening degree of the throttling part 20, wherein the second preset opening degree and the maximum opening degree of the throttling part 20 form a second preset ratio; the second preset ratio is smaller than the first preset ratio;
and, S245: comparing the first indoor temperature with the fifth preset temperature and the sixth preset temperature, and if the first indoor temperature is greater than or equal to the fifth preset temperature and less than the sixth preset temperature, performing step S246;
s246: acquiring a third preset opening degree of the throttling part 20, wherein the third preset opening degree and the maximum opening degree of the throttling part 20 form a third preset ratio; the third preset ratio is smaller than the second preset ratio.
In this embodiment, steps S241, S243, and S245 may be executed sequentially or simultaneously, for example, the third preset temperature and the fourth preset temperature form a first preset temperature zone, the fourth preset temperature and the fifth preset temperature form a second preset temperature zone, the fifth preset temperature and the sixth preset temperature form a third preset temperature zone, after the first indoor temperature is obtained, the first indoor temperature and the three preset temperature zones may be simultaneously compared, or may be sequentially compared, only the first indoor temperature is required to be effectively compared with the three preset temperature zones. Each preset temperature zone forms a mapping relation with a corresponding preset opening degree of the throttling part 20, if the first indoor temperature meets a certain preset temperature zone, the controller acquires the opening degree of the throttling part 20 corresponding to the temperature zone, and controls the throttling part 20 to adjust to the opening degree, so that the control on the throttling part 20 is more accurate, and the exhaust pressure of the compressor 11 in a certain temperature zone is more stable. In practical application, the fifth preset temperature is 25.5 ℃ to 26.5 ℃; the sixth preset temperature is 29.5 ℃ to 30.5 ℃; the second predetermined ratio is 0.45 to 0.55; the third predetermined ratio is 0.2 to 0.3; therefore, the opening change condition of the throttling part 20 is more reasonable, and the opening of the throttling part 20 in the corresponding temperature interval is more stable, so that the exhaust pressure of the compressor 11 is effectively reduced on the basis of ensuring the temperature regulation function of the compressor 11, and the energy consumption and the operation noise of the compressor 11 are reduced.
Further, as shown in fig. 5, the step S02 is followed by a step S04: if the first operation duration is less than the first preset duration, executing steps S5 to S7;
s5: acquiring the temperature in the third chamber and the current first operating power of the air conditioner;
s6: acquiring a preset opening degree of the throttling component 20 according to the third indoor temperature and the first operating power;
s7: and adjusting the throttling part 20 to the preset opening degree.
In this embodiment, the operation power of the air conditioner refers to the temperature adjustment capability of the air conditioner, for example, the larger the operation power of the air conditioner is, the shorter the time for the air conditioner to reach the indoor temperature to the target temperature is; the smaller the operating power of the air conditioner is, the longer the air conditioner takes to reach the indoor temperature to the target temperature. If the operation duration of the air conditioner has not reached the first preset duration, the preset opening degree of the throttling component 20 is obtained according to the current third indoor temperature and the first operation power, for example, the preset opening degree of the throttling component 20 forms a mapping relation with the preset temperature and the preset power at the same time, if the third indoor temperature meets a certain preset temperature, the first operation power meets a certain preset power, and the corresponding relation met at the same time enables the controller to obtain a certain corresponding preset opening degree of the throttling component 20 and enables the throttling component 20 to be adjusted to the preset opening degree, so that the control condition and the control result of the throttling component 20 can be more accurate, and the exhaust pressure of the compressor 11 can be more accurately controlled. In another embodiment, the third indoor temperature and the obtaining condition of the first operating power and the opening degree of the throttling element 20 may also be in a sequential satisfying relationship, specifically, the controller first determines whether the third indoor temperature satisfies a certain preset temperature, and if so, then determines whether the first operating power satisfies the preset power, so that the preset opening degree of the throttling element 20 is obtained after the third indoor temperature and the first operating power satisfy the obtaining condition in a sequential manner; if the third indoor temperature does not satisfy a certain preset temperature but satisfies another preset temperature, the first operating power does not need to be considered, and at this time, only one opening degree is preset for the throttling part 20 corresponding to the preset temperature, and the first operating power does not need to be considered, so that the preset temperature can be directly obtained.
Further, as shown in fig. 6, the step S6 includes:
s61: comparing the third indoor temperature with a seventh preset temperature and an eighth preset temperature; if the third indoor temperature is greater than or equal to the seventh preset temperature and less than the eighth preset temperature, executing step S62;
s62: comparing the first operating power with a first preset power; if the first operating power is greater than or equal to the first preset power, performing step S63; if the first operating power is less than the first preset power, performing step S64;
s63: acquiring a fourth preset opening degree of the throttling part 20, wherein the fourth preset opening degree and the maximum opening degree of the throttling part 20 form a fourth preset ratio;
s64: and acquiring a fifth preset opening degree of the throttling part 20, wherein the fifth preset opening degree and the maximum opening degree of the throttling part 20 form a fifth preset ratio.
In this embodiment, the seventh preset temperature and the eighth preset temperature form a fourth preset temperature zone, two preset opening degrees of the throttling component 20 corresponding to the fourth preset temperature zone are provided, the two preset opening degrees respectively form a further mapping relationship with the first preset power, if the third temperature is in the fourth preset temperature zone, the relationship between the first operating power and the first preset power needs to be further determined, and if the first operating power is greater than or equal to the first preset power, the fourth preset opening degree of the throttling component 20 is obtained; if the first operating power is less than the first preset power, the fifth preset opening of the throttling component 20 is obtained, so that the opening of the throttling component 20 can be controlled more accurately according to the room temperature and the operating power of the air conditioner, and the exhaust pressure of the compressor 11 is effectively adjusted on the basis of meeting the temperature adjusting function of the air conditioner. In practical application, the seventh preset temperature is 16.5 ℃ to 17.5 ℃, and the eighth preset temperature is 20.5 ℃ to 21.5 ℃; the fourth predetermined ratio is 0.45 to 0.55, and/or the fifth predetermined ratio is 0.9 to 1. Therefore, the opening change condition of the throttling part 20 is more reasonable, and the opening of the throttling part 20 in the corresponding temperature interval is more stable, so that the exhaust pressure of the compressor 11 is effectively reduced on the basis of ensuring the temperature regulation function of the compressor 11, and the energy consumption and the operation noise of the compressor 11 are reduced.
In another embodiment, the mapping relationship between the preset opening degree of the throttling element 20 and the preset temperature and the preset power further includes a fifth preset temperature zone and a sixth preset temperature zone, the fifth preset temperature zone and the sixth preset temperature zone respectively correspond to one preset opening degree of the throttling element 20, and if the third temperature zone is located in the fifth preset temperature zone or the sixth preset temperature zone, the controller may directly obtain the corresponding preset opening degree of the throttling element 20 without considering the satisfying condition of the first operating power, so as to make the opening degree control condition of the throttling element 20 in other temperature zones more reasonable. Specifically, the fourth preset temperature zone is the same as the first preset temperature zone, the fifth preset temperature zone and the sixth preset temperature zone are also the same as the second preset temperature zone and the third preset temperature zone, respectively, a sixth preset opening degree corresponding to the fifth preset temperature zone is the same as the second preset opening degree, and a seventh preset opening degree corresponding to the sixth preset temperature zone is the same as the third preset opening degree.
