It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The invention provides an air conditioner control method. The control method is particularly suitable for the new energy variable frequency air conditioner with the IPM module.
Fig. 1 is a schematic method diagram of an embodiment of an air conditioner control method provided by the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the air conditioner control method includes at least step S110 and step S120.
Step S110, after the compressor of the air conditioner is started, whether the outdoor environment temperature is larger than or equal to a set environment temperature judgment value is judged.
Specifically, since the higher the ambient temperature is, the worse the heat dissipation effect of the IPM module is, when it is determined that the outdoor ambient temperature is equal to or greater than a certain temperature value, that is, the set ambient temperature determination value, it is further determined whether the IPM module temperature protection is required. The value range of the set environment temperature judgment value is 40-45 ℃, for example, 42 ℃.
And step S120, if the outdoor environment temperature is judged to be greater than or equal to the set environment temperature judgment value, determining whether to control the compressor to stop according to whether the power supply voltage of the compressor is greater than or equal to the set voltage so as to protect the IPM module of the air conditioner.
When the IPM module provides the same compressor frequency, the larger the power supply voltage is, the larger the module heat productivity is, the larger the module temperature detection deviation is, the faster the module temperature rising speed is, the smaller the power supply voltage is, the smaller the module heat productivity is, the smaller the module temperature calibration deviation is, and the slower the module temperature rising speed is, so that when the outdoor environment temperature is judged to be greater than or equal to the set environment temperature judgment value, whether to control the compressor to stop or not is determined according to the size of the power supply voltage of the compressor, so as to perform temperature protection on the IPM module of the air conditioner.
Specifically, whether the power supply voltage of the compressor is greater than or equal to a set voltage is judged, and if the power supply voltage of the compressor is smaller than the set voltage, the air conditioner is controlled to operate according to a normal program until the air conditioner is shut down. If the power supply voltage of the compressor is judged to be greater than or equal to the set voltage, judging whether the IPM module temperature meets a preset condition; and if the IPM module temperature is judged to meet the preset condition, controlling the compressor to stop so as to protect the IPM module of the air conditioner. The set voltage may be, for example, 500V.
In one embodiment, the preset conditions are: the IPM module temperature t1 satisfies the following relation:
t1≥t2+k(U1-Uis provided with)
Wherein t2 is a set protection temperature value, which may be specificallyThe IPM module protection temperature value in the normal IPM module temperature protection determination logic is determined, that is, in the normal IPM module temperature protection determination logic, when the IPM module temperature reaches the set protection temperature value, the IPM module needs to be shut down for protection, that is, the compressor is shut down. U1 is the supply voltage for the compressor, UIs provided withFor the set voltage, k is a preset conversion coefficient (for example, the unit may be V/° c), that is, a difference between the compressor supply voltage U1 and the set voltage is converted into a temperature value, and the preset conversion coefficient k may be obtained through a plurality of experiments. The predetermined conversion coefficient k may be a negative value, so t2+ k (U1-U)Is provided with) And when the power supply voltage of the compressor is larger than t2, the larger the power supply voltage U1 is, the smaller the protection temperature value after IPM adjustment is, and the IPM module can be protected in advance under the condition that the power supply voltage of the compressor is larger.
According to the embodiment of the invention, when the outdoor environment temperature is higher (greater than or equal to the set environment temperature determination value) and the compressor power supply voltage is higher (greater than or equal to the set voltage), the protection temperature value of the IPM module is reduced by changing the protection temperature value of the IPM module, the IPM module is protected in advance, and the IPM module is prevented from being damaged due to untimely protection.
Fig. 2 is a method schematic diagram of another embodiment of the air conditioner control method provided by the invention.
As shown in fig. 2, according to another embodiment of the present invention, the air conditioning control method further includes step S130 and step S140.
Step S130, if it is determined that the outdoor environment temperature is less than the set temperature value, determining whether the IPM module temperature is greater than or equal to a set protection temperature value.
Step S140, if the IPM module temperature is judged to be greater than or equal to the set protection temperature value, the compressor is controlled to stop so as to protect the IPM module of the air conditioner.
The set protection temperature value may specifically be an IPM module protection temperature value in the IPM module temperature protection determination logic, and when the outdoor environment temperature does not reach the set temperature, the IPM module is directly shutdown-protected, that is, the compressor is shutdown, when the temperature of the IPM module reaches the set protection temperature value.
That is to say, when the outdoor environment temperature is determined to be less than the set temperature value, whether the compressor is stopped may be directly controlled according to whether the IPM module temperature is greater than or equal to the set protection temperature value, so as to perform temperature protection on the IPM module of the air conditioner, and if the IPM module temperature is greater than or equal to the set protection temperature value, which indicates that the temperature is higher, the compressor is controlled to be stopped, so as to perform temperature protection on the IPM module, so that the protection module is not burned out due to higher temperature.
For clearly explaining the technical solution of the present invention, the following describes an execution flow of the air conditioner control method provided by the present invention with a specific embodiment.

If the outdoor environment temperature T1 of the air conditioning unit is judged to meet the condition that T1 is more than or equal to TIs provided withThen, it is continuously determined whether the compressor power supply voltage U1 satisfies U1 ≧ UIs provided withIf not, U1 is more than or equal to UIs provided withAnd the air conditioning unit operates according to a normal program until the unit is stopped. If the condition that U1 is more than or equal to U is metIs provided withJudging whether the IPM module temperature t1 meets the condition that t1 is more than or equal to t2+ k (U1-U)Is provided with) If the condition is met, the air conditioning unit carries out IPM module protection, the compressor stops running, and the unit stops running; if this condition is not met, the air conditioning unit is operated according to the normal program until the unit is stopped (k is the compensation factor, U1 is the compressor supply voltage, U1Is provided withTo a set voltage).
The invention provides an air conditioner control device. The control device is particularly suitable for the new energy variable frequency air conditioner with the IPM module.
Fig. 4 is a block diagram of an embodiment of an air conditioning control apparatus according to the present invention. As shown in fig. 4, the air conditioning control device 100 includes a determination unit 110 and a control unit 120.

When the IPM module provides the same compressor frequency, the larger the power supply voltage is, the larger the module heat productivity is, the larger the module temperature detection deviation is, the faster the module temperature rising speed is, the smaller the power supply voltage is, the smaller the module heat productivity is, the smaller the module temperature calibration deviation is, and the slower the module temperature rising speed is, so that when the outdoor environment temperature is judged to be greater than or equal to the set environment temperature judgment value, whether to control the compressor to stop or not is determined according to the size of the power supply voltage of the compressor, so as to perform temperature protection on the IPM module of the air conditioner.
Specifically, whether the power supply voltage of the compressor is greater than or equal to a set voltage is judged, and if the power supply voltage of the compressor is smaller than the set voltage, the air conditioner is controlled to operate according to a normal program until the air conditioner is shut down. If the power supply voltage of the compressor is judged to be greater than or equal to the set voltage, judging whether the IPM module temperature meets a preset condition; and if the IPM module temperature is judged to meet the preset condition, controlling the compressor to stop so as to protect the IPM module of the air conditioner.

U1 is the supply voltage for the compressor, UIs provided withFor the set voltage, k is a predetermined conversion coefficient (for example, the unit may be V/° c), that is, a difference between the compressor supply voltage U1 and the set voltage is converted into a temperature value, and the predetermined conversion coefficient k may be obtained through a plurality of experiments. The predetermined conversion coefficient k may be a negative value, so t2+ k (U1-U)Is provided with) And when the power supply voltage of the compressor is larger than t2, the larger the power supply voltage U1 is, the smaller the protection temperature value after IPM adjustment is, and the IPM module can be protected in advance under the condition that the power supply voltage of the compressor is larger.
