With reference to fig. 1 and 2, the embedded air conditioner includes a plurality of air outlets, each air outlet is provided with an air deflector, and an indoor heat exchanger 10 and a throttling device 20 are arranged inside each air deflector; each air deflector is provided with an independent driving mechanism, and the independent control of each air deflector is realized under the action of the driving mechanism; each indoor heat exchanger 10 and the throttling device 20 form an independent refrigerant loop with the outdoor heat exchanger 30 and the compressor 40 through pipelines; a plurality of indoor heat exchangers 10 are in parallel relationship with the throttling device 20. In the disclosed embodiment, the air outlets include A, B, C, D four air outlets. Optionally, a temperature sensor is disposed at an inlet and an outlet of each indoor heat exchanger 10, and is configured to detect a temperature of a refrigerant at the inlet and the outlet of the indoor heat exchanger 10.
Referring to fig. 3, an embodiment of the present disclosure provides a control method for an embedded air conditioner, including:
s101, detecting the temperature of the air outlet area of each air deflector by a sensor.
Here, a temperature sensor is disposed at the air outlet of each air deflector to detect the temperature of the air outlet area of each air deflector.
And S102, the processor adjusts the opening degree of the throttling device corresponding to the air deflector of the throttling device under the condition that the difference value between the detected temperature and the set temperature of the air outlet area of the corresponding air deflector does not meet a preset condition.
In the embodiment of the disclosure, the set temperature of each air outlet area of the air guide plate may be the same, partially the same or completely different. Therefore, the temperature of each air outlet area of the air guide plate is detected, and the detected temperature is compared with the set temperature of the air outlet area of the air guide plate. And when the difference between the air inlet area and the air outlet area does not meet the preset condition, adjusting the opening of the corresponding throttling device so as to adjust the temperature of the air outlet area of the air deflector. Here, the preset condition refers to a temperature threshold, for example, the temperature threshold takes a value of ± 1 ℃; the preset conditions are (-1 ℃,1 ℃). And if the difference value between the detected temperature and the set temperature does not meet the preset condition, adjusting the opening of the throttling device. For example, the difference is 2 ℃, and at this time, the throttling device needs to be adjusted to adjust the refrigerant flow of the indoor heat exchanger, so as to improve the heat exchange efficiency, and the temperature of the air outlet area of the air deflector reaches the set temperature. It can be understood that when the difference between the detected temperature and the set temperature of the air outlet area of the air deflectors does not satisfy the preset condition, the throttling devices corresponding to the air deflectors need to be adjusted. The temperature of a plurality of air-out regions is adjusted in step to make the temperature of each air-out region all satisfy its settlement temperature.
By adopting the control method for the embedded air conditioner provided by the embodiment of the disclosure, the opening degree of the throttling device corresponding to the air deflector can be adjusted when the temperature of the air outlet area of the air deflector and the set temperature of the air outlet area do not meet the preset condition. The flow of the refrigerant of the indoor heat exchanger is adjusted, the heat exchange efficiency is improved, and the temperature of the air outlet area of the air deflector reaches the set temperature. Like this, the air-out temperature at the aviation baffle is great with the settlement temperature difference, and when can't satisfy the temperature demand through adjusting the aviation baffle angle, adjusts the demand of throttling arrangement aperture in order to realize the differentiation temperature.
Alternatively, as shown in fig. 4, in step S102, the adjusting, by the processor, the opening degree of the throttling device corresponding to the air deflector includes:
and S121, detecting the temperature of the inlet and the outlet of the indoor heat exchanger corresponding to the air deflector by using the temperature sensor.
And S122, determining the target temperature of the inlet and the outlet of the indoor heat exchanger of the throttling device by the processor according to the running mode and the set temperature of the embedded air conditioner.
And S123, adjusting the opening degree of the throttling device corresponding to the air deflector by the processor according to the detected temperature of the inlet and the outlet of the throttling device and the target temperature.
In the embodiment of the disclosure, the temperature of the refrigerant at the inlet and the outlet of the indoor heat exchanger is detected by the temperature sensors arranged at the inlet and the outlet of the indoor heat exchanger. And then, determining the target temperature of the inlet and the outlet of the indoor heat exchanger according to the operation mode of the embedded air conditioner and the set temperature of the air outlet area. Here, the operation mode of the air conditioner mainly refers to a cooling mode or a heating mode. Under the same set temperature, the target temperatures of the inlet and the outlet of the indoor heat exchanger are different under different operation modes. Generally, in the cooling mode, the difference between the target temperature of the inlet and the outlet of the indoor heat exchanger and the set temperature of the air outlet area is smaller than that in the heating mode. The target temperature can be determined through the incidence relation between the set temperature of the air outlet area and the target temperature of the inlet and the outlet in different operation modes.
After the target temperature is determined, the opening degree of the throttling device is adjusted based on the detected temperature of the inlet and the outlet and the target temperature. Here, the opening degree is generally adjusted according to the magnitude relation between the detected temperature and the target temperature. For example, in the cooling mode, if the detected temperature is higher than the target temperature, the opening degree of the throttle device is increased, and if not, the opening degree of the throttle device is decreased. In the heating mode, when the detected temperature is higher than the target temperature, the opening degree of the throttling device is reduced, otherwise, the opening degree is increased.
In the heating mode, the temperature difference between the inlet and the outlet of the indoor evaporator is large, and in this case, the detection temperature is an average value of the inlet and outlet detection temperatures. In the cooling mode, the temperature difference between the inlet and the outlet of the indoor evaporator is small, and in this case, the detected temperature may be the average value of the inlet and the outlet detected temperatures, or the detected temperature of the inlet or the detected temperature of the outlet. Note that the target temperatures of the inlet and outlet are the same. Therefore, the target temperature is determined by detecting the temperature of the refrigerant at the inlet and the outlet of the indoor heat exchanger, and the opening degree of the throttling device is further adjusted. The control precision is higher, and the temperature of each air outlet area can reach the set temperature.
Optionally, in step S122, the processor determines the target temperature of the inlet and the outlet of the indoor heat exchanger according to the operation mode and the set temperature of the embedded air conditioner, including:
calculating T under the condition that the embedded air conditioner is in a refrigeration modeEyes of a user＝TIs provided with-ΔT1(ii) a Calculating T under the condition that the embedded air conditioner is in a heating modeEyes of a user＝TIs provided with+ΔT2； wherein ,TEyes of a userIs the target temperature T of the inlet and outlet of the indoor heat exchangerIs provided withFor setting temperature, Delta T, of air outlet region of air deflector1Is a first temperature difference, Δ T2Is the second temperature difference.
In the embodiment of the disclosure, the calculation modes of the inlet and outlet target temperatures of the indoor heat exchanger are different in different operation modes of the air conditioner. Generally, in a refrigeration mode, the target temperature of an inlet and an outlet is lower than the set temperature of an air outlet area; in the heating mode, the target temperature of the inlet and the outlet is higher than the set temperature of the air outlet area. Further, in different operation modes, the difference between the target temperature of the inlet and the target temperature of the outlet and the set temperature of the air outlet area can be different, and the difference in the refrigeration mode is smaller than or equal to the difference in the heating mode, that is, the first temperature difference is smaller than or equal to the second temperature difference. Therefore, the target temperature of the inlet and the outlet of the heat exchanger can be accurately determined, so that the opening degree of the throttling device can be accurately adjusted, and the heat exchange efficiency is improved.
Alternatively, as shown in fig. 5, in step S123, the processor adjusts the opening degree of the throttling device corresponding to the air deflector according to the detected temperature of the inlet and the outlet and the target temperature, and includes:
s1231, calculating the ratio of the target temperature to the average value of the detected temperatures by the processor; wherein, the average value of the detection temperature is the average value of the detection temperature of the inlet and the detection temperature of the outlet.
And S1232, adjusting the opening of the throttling device by the processor according to the size relation between the ratio and the preset threshold value.
In the embodiment of the disclosure, because the indoor heat exchanger exchanges heat with air, the temperature difference exists between the inlet and outlet temperatures of the indoor heat exchanger. In order to improve the accuracy of the control, here, the target temperature is compared with the average value of the detected temperatures of the inlet and outlet. The regulation principle of the throttling device is mainly based on a PID (Proportion-integration-differentiation) control algorithm to regulate, namely, the opening degree of the throttling device is controlled by the average value of the target temperature and the detected temperature after the calculation of a PID controller. Specifically, the ratio of the target temperature to the average value of the detected temperatures is calculated, and if the ratio is greater than a preset threshold value and the air conditioner is in the cooling mode, the opening degree of the throttling device is decreased. And if the ratio is larger than a preset threshold value and the air conditioner is in a heating mode, increasing the opening degree of the throttling device. Therefore, the opening degree of the throttling device can be accurately controlled according to the size relation between the ratio and the preset threshold value, so that the inlet and outlet temperatures of the indoor heat exchanger reach the target temperature. It should be noted that, because the indoor heat exchanger has heat exchange, the temperature of its inlet and outlet will have a difference. When the temperature difference of the inlet and the outlet is within +/-0.5 ℃ of the target temperature, the inlet and the outlet temperature can be determined to reach the target temperature. Furthermore, it is understood that if the ratio is equal to the preset threshold, the current opening degree of the adjusting means is maintained.
Optionally, in step S1232, the processor adjusts the opening degree of the throttling device according to a magnitude relationship between the ratio and a preset threshold, including:
the method comprises the following steps that under the condition that the embedded air conditioner is in a refrigeration mode, if the ratio is larger than a preset threshold value, the opening degree of a throttling device is reduced by a processor; if the ratio is smaller than a preset threshold value, the opening degree of the throttling device is increased; or
Under the condition that the embedded air conditioner is in a heating mode, if the ratio is greater than a preset threshold value, the opening degree of the throttling device is increased by the processor; and if the ratio is smaller than the preset threshold value, reducing the opening degree of the throttling device.
In the embodiment of the disclosure, in the cooling mode, if the ratio of the target temperature of the inlet and the outlet of the indoor heat exchanger to the average value of the detected temperatures is greater than the preset threshold, it indicates that the temperature of the air outlet area is lower than the set temperature. At the moment, the opening degree of the throttling device is reduced, and the flow rate of the refrigerant is reduced, so that the temperature of the air outlet area is improved. Otherwise, the opening degree of the throttling device is increased. Likewise, a regulating strategy for the throttle device in heating mode is available.
Optionally, the preset threshold is determined by:
the processor acquires the current outdoor environment temperature; and determining a preset threshold corresponding to the current outdoor environment temperature according to the mapping relation between the outdoor environment temperature and the preset threshold.
Here, the current temperature of the outdoor environment may be acquired by an outdoor temperature sensor, or the processor acquires the current temperature of the outdoor environment of the area where the air conditioner is located from the cloud server. Determining a preset threshold corresponding to the current outdoor environment temperature according to a preset mapping relation; the value range of the preset threshold is (0, 2.) in the embodiment of the present disclosure, the outdoor temperature is divided into a plurality of intervals, and different areas correspond to different preset thresholds.
Optionally, in the cooling mode, the higher the outdoor ambient temperature is, the larger the preset threshold is. In the heating mode, the higher the outdoor environment temperature is, the smaller the preset threshold value is.
In the refrigeration mode, the higher the outdoor temperature is, the larger the value of the preset threshold value is. In particular, when the value of the preset threshold is greater than or equal to 1, it means that the opening degree of the throttle device is increased as long as the target temperature is less than the average value of the detected temperatures. Because the outdoor temperature is high, the opening degree of the throttling device is large, and the temperature change is not large when the opening degree of the throttling device is adjusted to be large. Under the condition, the opening degree of the large throttling device is reduced, the temperature of the indoor heat exchanger is reduced, and the air outlet temperature of the air outlet area is reduced, so that the air outlet temperature reaches the set temperature. Likewise, the lower the outdoor temperature, the smaller the preset threshold value. In particular, the area of the preset threshold is smaller than 1, for example, 0.8. It is stated that when the target temperature is lower than the average value of the detected temperatures and the difference between the target temperature and the detected temperatures is large, the ratio of the target temperature to the detected temperatures is smaller than 0.8. At this time, the opening degree of the throttle device is adjusted to be large. Because the outdoor environment temperature is lower, the output power of the refrigerating system is relatively lower, and the opening degree of the throttling device is smaller. And if the difference value between the target temperature and the average value of the detected temperatures is smaller, the opening degree of the throttling device is adjusted to be larger. Overshoot may result, i.e., the detected temperature is below the target temperature, which may create a poor experience for the user. Similarly, the reason why the preset threshold is smaller as the outdoor temperature is higher in the heating mode can be known. Optionally, in different operation modes, the mapping relationship between the outdoor ambient temperature and the preset threshold is as shown in table 1.
TABLE 1
Referring to fig. 6, an embodiment of the present disclosure provides another control method for an embedded air conditioner, including:
s201, the temperature of the air outlet area of each air deflector is detected by a sensor.
S202, the processor adjusts the angle and the swinging frequency of the air deflector under the condition that the difference value between the detected temperature and the set temperature of the air outlet area of the corresponding air deflector does not meet the preset condition.
And S203, after the preset time is long, under the condition that the difference value between the detected temperature and the set temperature of the air outlet area of the corresponding air guide plate does not meet the preset condition, adjusting the opening degree of the throttling device corresponding to the air guide plate.
In the embodiment of the disclosure, if the temperature of the air outlet area of the air deflector does not reach the set temperature, the air outlet temperature can reach the set temperature by adjusting the angle and the swing frequency of the air deflector. After the angle of the air deflector and the swing frequency are adjusted for a period of time, if the air outlet temperature does not reach the set temperature in 20 minutes, the opening degree of the throttling device corresponding to the air deflector is adjusted. In some embodiments, the user sets the air outlet angle of the air deflector. At this time, the opening degree of the throttling device is directly adjusted if the temperature cannot be improved by adjusting the angle of the air deflector. Like this, when satisfying user's air-out angle, satisfy the user to the demand of temperature.
Optionally, in step S202, when the difference between the detected temperature and the set temperature of the air outlet area of the air deflector does not satisfy the preset condition, the processor adjusts the angle and the frequency of the swing of the air deflector, including:
when the difference value between the detected temperature and the set temperature of the air outlet area of the corresponding air guide plate does not meet the preset condition and the detected temperature is higher than the set temperature, the angle of the air guide plate is reduced, and the swing frequency of the air guide plate is reduced; or
And under the condition that the difference value between the detected temperature and the set temperature of the corresponding air outlet area of the air guide plate does not meet the preset condition and the detected temperature is lower than the set temperature, the processor increases the angle of the air guide plate and improves the swing frequency of the air guide plate.
In the embodiment of the disclosure, when the difference between the detected temperature of the air outlet area and the set temperature does not satisfy the preset condition, and the detected temperature is greater than the set temperature, it indicates that the temperature is higher. Therefore, the angle of the air deflector is reduced, and the air output is reduced. Meanwhile, the swing frequency is reduced, and the disturbance of heat exchange air flow is reduced. Thereby reducing the temperature. Similarly, when the temperature is low, the temperature can be increased by increasing the angle and the swing frequency of the air deflector.
Referring to fig. 7, an embodiment of the present disclosure provides a control device for an embedded air conditioner, including a detection module 71 and an adjustment module 72. The detection module 71 is configured to detect the temperature of the air outlet area of each air deflector; the adjusting module 72 is configured to adjust the opening degree of the throttling device corresponding to the air deflector when the difference between the detected temperature and the set temperature of the air outlet area of the corresponding air deflector does not satisfy the preset condition.
By adopting the control device for the embedded air conditioner, the opening degree of the throttling device corresponding to the air deflector can be adjusted when the temperature of the air outlet area of the air deflector and the set temperature of the air outlet area do not meet the preset condition. The flow of the refrigerant of the indoor heat exchanger is adjusted, the heat exchange efficiency is improved, and the temperature of the air outlet area of the air deflector reaches the set temperature. Like this, the air-out temperature at the aviation baffle is great with the settlement temperature difference, and when can't satisfy the temperature demand through adjusting the aviation baffle angle, adjusts the demand of throttling arrangement aperture in order to realize the differentiation temperature.
