Referring to fig. 1 and 2, the air conditioner includes a plurality of air outlets, each of which is provided with an air deflector, and an indoor heat exchanger 10 and a throttling device 20 disposed inside each air deflector; each air deflector is provided with an independent driving mechanism, and 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 through a pipeline, an outdoor heat exchanger 30 and a compressor 40; the plurality of indoor heat exchangers 10 are in parallel relationship with the throttle device 20. In the embodiment of the disclosure, the air outlet includes A, B, C, D four air outlets. Optionally, temperature sensors are disposed at the inlet and outlet of each indoor heat exchanger 10, for detecting the temperature of the refrigerant at the inlet and 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 provided at the air outlet of each air deflector to detect the temperature of the air outlet area of each air deflector.
S102, the processor adjusts the opening 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 the preset condition.
In the embodiment of the disclosure, the set temperature of the air outlet area of each air deflector may be the same, partially the same or completely different. Therefore, the temperature of the air outlet area of each air deflector is detected, and the detected temperature is compared with the set temperature of the air outlet area of the air deflector. And when the difference value of the two is not satisfied with the preset condition, adjusting the opening of the corresponding throttling device 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 condition is (-1 deg.c, 1 deg.c). And if the difference 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 ℃, at this time, the throttling device is required 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 areas of the air deflectors does not meet the preset condition, the corresponding throttling device of the air deflectors needs to be adjusted. The temperatures of the air outlet areas are synchronously regulated so that the temperatures of the air outlet areas meet the set temperatures.
By adopting the control method for the embedded air conditioner, which is provided by the embodiment of the disclosure, 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 opening of the throttling device corresponding to the air deflector can be adjusted. The refrigerant flow 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 and the settlement temperature of aviation baffle differ greatly, and can't satisfy the temperature demand through adjusting aviation baffle angle, adjust throttling arrangement aperture in order to realize the demand of differentiation temperature.
Optionally, as shown in fig. 4, in step S102, the processor adjusts the opening of the throttling device corresponding to the air deflector, including:
s121, detecting the temperature of an inlet and an outlet of the indoor heat exchanger corresponding to the air deflector by a temperature sensor.
S122, the processor determines the target temperature of the inlet and outlet of the indoor heat exchanger of the throttling device according to the running mode and the set temperature of the embedded air conditioner.
And S123, the processor adjusts the opening of the throttling device corresponding to the air deflector according to the detected temperature and the target temperature of the inlet and the outlet of the throttling device.
In the embodiment of the disclosure, the temperature of the refrigerant at the inlet and the outlet of the indoor heat exchanger is detected through 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 outlet of the indoor heat exchanger according to the running 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. At the same set temperature, the target temperatures of the inlet and outlet of the indoor heat exchanger are different in different operation modes. In general, in the cooling mode, the difference between the target temperature of the inlet and outlet of the indoor heat exchanger and the set temperature of the air outlet area is smaller than the difference between the target temperature and the set temperature in the heating mode. The target temperature can be determined through the association relation between the set temperature of the air outlet area and the target temperature of the inlet and the outlet under different operation modes.
After the target temperature is determined, the opening degree of the throttle 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 the detected temperature is lower than the target temperature, the opening degree of the throttle device is decreased. In the heating mode, when the detected temperature is greater than the target temperature, the opening degree of the throttling device is reduced, and otherwise, the opening degree is increased.
In addition, in the heating mode, the temperature difference between the inlet and outlet of the indoor evaporator is large, and in this case, the detected temperature means an average value of the detected temperatures of the inlet and outlet. In the refrigeration mode, the temperature difference between the inlet and the outlet of the indoor evaporator is smaller, and in this case, the detected temperature may be an average value of the detected temperatures of the inlet and the outlet, or may be the detected temperature of the inlet or the detected temperature of the outlet. The target temperatures of the inlet and outlet are the same. In this way, the target temperature is determined by detecting the temperature of the refrigerant at the inlet and the outlet of the indoor heat exchanger, and then the opening of the throttling device is 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 a target temperature of the inlet and outlet of the indoor heat exchanger according to the operation mode and the set temperature of the embedded air conditioner, including:
under the condition that the embedded air conditioner is in a refrigerating mode, calculating T Order of (A) ＝T Is provided with -ΔT 1 The method comprises the steps of carrying out a first treatment on the surface of the Under the condition that the embedded air conditioner is in a heating mode, calculating T Order of (A) ＝T Is provided with +ΔT 2； wherein ,TOrder of (A) T is the target temperature of the inlet and outlet of the indoor heat exchanger Is provided with For the set temperature of the air outlet area of the air deflector, delta T 1 For a first temperature difference, deltaT 2 Is the second temperature difference.
In the embodiment of the disclosure, under different operation modes of the air conditioner, the calculation modes of the inlet and outlet target temperatures of the indoor heat exchanger are different. In the refrigeration mode, the target temperature of the inlet and the outlet is lower than the set temperature of the 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 outlet and the set temperature of the air outlet area can also be different, and the difference in the refrigeration mode is smaller than or equal to the difference in the heating mode, namely 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.
Optionally, as shown in fig. 5, in step S123, the processor adjusts the opening of the throttling device corresponding to the air deflector according to the detected temperature of the inlet and the outlet and the target temperature, including:
s1231, the processor calculates the ratio of the target temperature to the average value of the detected temperature; the average value of the detected temperatures is the average value of the detected temperatures of the inlet and the outlet.
S1232, the processor adjusts the opening of the throttling device according to the magnitude relation between the ratio and the preset threshold.
In the embodiment of the disclosure, the indoor heat exchanger exchanges heat with air, so that the temperature difference exists between the inlet and outlet temperatures of the indoor heat exchanger. In order to improve the accuracy of the control, the target temperature is compared with the average value of the detected temperatures of the inlet and outlet. The regulating principle of the throttling device is mainly based on a PID (Proportion-Integral-Differential) control algorithm for regulating, namely, the opening degree of the throttling device is controlled after the average value of the target temperature and the detected temperature is calculated by a PID controller. Specifically, a ratio of the target temperature to an 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 a cooling mode, the opening degree of the throttle device is reduced. And if the ratio is greater than the preset threshold value and the air conditioner is in the 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 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. The difference between the inlet and outlet temperatures of the indoor heat exchanger is caused by the heat exchange. When the temperature difference of the inlet and the outlet is within +/-0.5 ℃ of the target temperature, the inlet and the outlet can be determined to reach the target temperature. Furthermore, it is understood that if the ratio is equal to the preset threshold value, the opening degree of the current adjusting means is maintained.
Optionally, in step S1232, the processor adjusts the opening of the throttle device according to the magnitude relation between the ratio and the preset threshold, including:
the processor reduces the opening of the throttling device under the condition that the embedded air conditioner is in a refrigerating mode if the ratio is larger than a preset threshold value; if the ratio is smaller than a preset threshold value, increasing the opening of the throttling device; or alternatively
The processor increases the opening of the throttling device if the ratio is greater than a preset threshold under the condition that the embedded air conditioner is in a heating mode; 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 refrigeration mode, if the ratio of the target temperature of the inlet and outlet of the indoor heat exchanger to the average value of the detected temperatures is greater than a preset threshold value, the temperature of the air outlet area is indicated to be lower than the set temperature. At this time, the opening degree of the throttling device is reduced, and the flow rate of the refrigerant is reduced so as to improve the temperature of the air outlet area. Otherwise, the opening degree of the throttle device is increased. Likewise, a regulating strategy of the throttle device in the heating mode can be obtained.
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 temperature of the current outdoor environment may be obtained by an outdoor temperature sensor, or the processor may obtain the temperature of the current outdoor environment of the area where the air conditioner is located from a cloud server. Further, according to a preset mapping relation, a preset threshold corresponding to the current outdoor environment temperature is determined; in the embodiment of the 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, the greater the preset threshold. In the heating mode, the higher the outdoor ambient temperature is, the smaller the preset threshold value is.
In the refrigeration mode, the higher the outdoor temperature is, the larger the preset threshold value is. In particular, when the value of the preset threshold is greater than or equal to 1, it is explained that the opening degree of the throttle device is increased as long as the target temperature is smaller than the average value of the detected temperatures. Because the outdoor temperature is higher, the opening degree of the throttling device is larger, and the opening degree of the throttling device is adjusted to be larger at the moment, so that the temperature change is not larger. Under the condition, the opening degree of the throttling device is increased, so that the temperature of the indoor heat exchanger is reduced, the air outlet temperature of the air outlet area is reduced, and the air outlet temperature reaches the set temperature. Similarly, the lower the outdoor temperature, the smaller the preset threshold value. In particular, the region of the predetermined threshold is smaller than 1, for example, a value of 0.8. It is indicated that when the target temperature is smaller than the average value of the detected temperatures and the difference between the target temperature and the detected temperature is larger, the ratio of the target temperature and the detected temperature is smaller than 0.8. At this time, the opening degree of the throttle device is increased. Because the temperature is lower in the outdoor environment, the output power of the refrigerating system is relatively lower, and the opening degree of the throttling device is smaller. And if the average value difference between the target temperature and the detected temperature is smaller, the opening degree of the throttling device is increased. An overshoot may result, i.e., the detected temperature is below the target temperature, which may create a bad experience for the user. Similarly, the reason why the preset threshold value 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 environment temperature and the preset threshold is shown in table 1.
TABLE 1
As shown in fig. 6, an embodiment of the present disclosure provides another control method for an embedded air conditioner, including:
s201, detecting the temperature of the air outlet area of each air deflector by a sensor.
S202, the processor adjusts the angle and the swing frequency of the air deflector under the condition that the difference value between the detected temperature and the set temperature of the corresponding air deflector air outlet area does not meet the preset condition.
And S203, after the preset time, adjusting the opening of the throttling device corresponding to 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.
In the embodiment of the disclosure, if the temperature of the air outlet area of the air guide plate 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 guide plate. After the angle and the swing frequency of the air deflector are adjusted for a period of time, if the air outlet temperature still does not reach the set temperature for 20 minutes, the opening of the throttling device corresponding to the air deflector is adjusted. In some embodiments, the user sets the air outlet angle of the air deflection. At this time, the temperature cannot be improved by adjusting the angle of the air guide plate, and the opening degree of the throttle device is directly adjusted. Thus, the air outlet angle of the user is met, and meanwhile, the requirement of the user on the temperature is met.
Optionally, in step S202, the processor adjusts the angle and the swing frequency of 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 meet the preset condition, including:
the processor adjusts the angle of the air deflector and reduces the swinging frequency of the air deflector when the difference between the detected temperature and the set temperature of the corresponding air deflector air outlet area does not meet the preset condition and the detected temperature is larger than the set temperature; or (b)
The processor increases the angle of the air deflector and increases the swing frequency of the air deflector when the difference between the detected temperature and the set temperature of the corresponding air deflector air outlet area does not meet the preset condition and the detected temperature is smaller than the set temperature.
In the embodiment of the disclosure, when the difference between the detected temperature and the set temperature in the air outlet area does not meet the preset condition and the detected temperature is greater than the set temperature, the temperature is higher. Therefore, the angle of the air deflector is reduced, and the air output is reduced. And meanwhile, the swing frequency is reduced, and the disturbance of the heat exchange air flow is reduced. Thereby lowering the temperature. Likewise, when the temperature is indicated to be low, the temperature can be raised by increasing the angle and the swing frequency of the air deflector.
As shown in 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 a temperature of an air outlet area of each air deflector; the adjustment module 72 is configured to adjust the opening of the throttle device corresponding to the air deflector if the difference between the detected temperature and the set temperature of the corresponding air deflector outlet area does not satisfy the preset condition.
By adopting the control device for the embedded air conditioner, provided by the embodiment of the disclosure, 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 opening degree of the throttling device corresponding to the air deflector can be adjusted. The refrigerant flow 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 and the settlement temperature of aviation baffle differ greatly, and can't satisfy the temperature demand through adjusting aviation baffle angle, adjust throttling arrangement aperture in order to realize the demand of differentiation temperature.
