All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.
It should be noted that the terms "first," "second," and the like in the description of the present application and the above-described figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in sequences other than those illustrated or otherwise 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.
As shown in fig. 1, the present application proposes a first air conditioner operation control method, which may include the following steps:
s101, controlling the operation frequency of a compressor to be adjusted to a target frequency from the current operation frequency under the condition that the current temperature of an intelligent power module IPM is determined to be larger than a preset overtemperature limit value; the target frequency is obtained by subtracting a first preset frequency from the current operating frequency.
The preset overtemperature limit may be an overtemperature limit of IPM, such as 85 ℃. It should be noted that the preset overtemperature limit may be set by a technician according to actual situations, which is not limited in the present application.
Specifically, the present application may detect the current temperature of the IPM in real time during the operation of the air conditioner. Alternatively, the present application may detect the temperature of the IPM by sampling the resistance.
Specifically, after the current temperature of the IPM is detected, the present temperature of the IPM is judged to be greater than the preset overtemperature limit value, if yes, the present temperature of the IPM can be indicated to be overturned, the present running frequency of the compressor is high, at this time, the present running frequency of the compressor can be reduced by a certain value to cool the IPM in a corresponding safety control mode. At this time, the present application may determine the current operating frequency of the compressor, reduce the current operating frequency by a first preset frequency to obtain a target frequency, and adjust the operating frequency of the compressor from the current operating frequency to the target frequency.
The first preset frequency is the value of the frequency of the compressor to be reduced. It should be noted that, this application can set up first default frequency by technicians according to actual conditions for after reducing first default frequency, can carry out effective cooling, such as 10 hz, to IPM.
Alternatively, the first preset frequency may be a value corresponding to the current operating frequency. According to the method and the device, a technician can set corresponding first preset frequencies capable of enabling the IPM to be cooled to a safe range for different operation frequencies in advance.
Specifically, if the current temperature of the IPM is not greater than the preset overtemperature limit, it may be indicated that the current temperature of the IPM is not overrun, and the IPM is in a safer operating condition.
S102, detecting the temperature of the IPM and taking the temperature as a target temperature after the compressor operates at the target frequency for a first preset period of time.
The first preset duration may be set by a technician according to practical situations, for example, 3 minutes, which is not limited in the present application. It will be appreciated that the IPM may continue to be cooled down during a period of time when the compressor is operating at a reduced frequency.
It should be noted that, the present application may detect the temperature of the IPM after reducing the operating frequency of the compressor and running the compressor for a certain period of time, and if the temperature of the IPM is reduced to a safe value, may slowly increase the operating frequency of the compressor until the temperature of the IPM reaches a certain interval. At this time, the application can gradually increase the frequency of the compressor under the condition of avoiding the IPM overtemperature, improve the indoor refrigeration efficiency and ensure the user experience.
Specifically, after the operation frequency of the compressor is reduced, the compressor is controlled to operate for a first preset time period at the reduced frequency, namely the target frequency, so as to cool down the IPM, and after the compressor is operated for the first preset time period at the target frequency, the temperature of the IPM is detected and used as the target temperature.
S103, judging whether the target temperature is smaller than a preset temperature threshold, if yes, executing step S104.
The preset temperature threshold may be slightly less than a preset over-temperature limit. For example, when the preset overtemperature limit is 85 degrees celsius, the preset temperature threshold may be 84.5 degrees celsius.
And S104, gradually increasing the operation frequency of the compressor until the temperature of the IPM is not less than a preset temperature threshold value and not more than a preset overtemperature limit value.
It should be noted that, the present application may gradually increase the operation frequency of the compressor when the target temperature is less than the preset temperature threshold, detect the temperature of the IPM during the period of increasing the operation frequency of the compressor, stop increasing the operation frequency of the compressor when the temperature of the IPM reaches a range not less than the preset temperature threshold and not greater than the preset overtemperature limit, and control the operation of the compressor under the operation frequency after stopping the increase. For example, when the target temperature is less than the preset temperature threshold, the present application may raise the operating frequency of the compressor by 2, and detect, after the compressor is operated for 2 minutes, whether the temperature of the IPM is not less than the preset temperature threshold and not greater than the preset overtemperature limit, if not, raise the operating frequency of the compressor by 2.5, and detect, after the compressor is operated for 3 minutes, whether the temperature of the IPM is not less than the preset temperature threshold and not greater than the preset overtemperature limit, if not, raise the operating frequency of the compressor by 2, and detect, after the compressor is operated for 2 minutes, whether the temperature of the IPM is not less than the preset temperature threshold and not greater than the preset overtemperature limit, if yes, stop raising the operating frequency of the compressor, and control the compressor to operate at the operating frequency after stopping the raising.
According to the operation control method of the air conditioner, under the condition that the current temperature of the intelligent power module IPM is determined to be greater than the preset over-temperature limit value, the operation frequency of the compressor is controlled to be adjusted from the current operation frequency to the target frequency; the target frequency is obtained by subtracting a first preset frequency from the current operating frequency; detecting the temperature of the IPM and taking the temperature as a target temperature after the compressor operates at the target frequency for a first preset period of time; and judging whether the target temperature is smaller than a preset temperature threshold, if so, gradually increasing the operating frequency of the compressor until the temperature of the IPM is not smaller than the preset temperature threshold and not larger than a preset overtemperature limit. According to the method and the device, under the condition that the IPM overtemperature is determined, the running frequency of the compressor is reduced, and then the running frequency of the compressor is gradually increased until the temperature of PM is not less than the preset temperature threshold value and not greater than the preset overtemperature limit value, so that the refrigerating efficiency of the compressor is ensured, and the IPM overtemperature is effectively avoided while the user experience is improved.
As shown in fig. 2, the present application proposes a second air conditioner operation control method, in which step S104 may include:
s201, raising the operation frequency of the compressor by a second preset frequency.
The second preset frequency may be a frequency of each boost of the compressor.
It should be noted that the second preset frequency may correspond to the first preset frequency. The method and the device can set the corresponding second preset frequency according to the first preset frequency by a technician, so that the IPM can not be overtemperature again under the condition that the frequency of the compressor is gradually increased.
S202, detecting the temperature of the IPM after the compressor runs for a second preset time period.
The second preset duration may be set by a technician according to practical situations, which is not limited in this application, and may be set to 2 minutes, for example.
Specifically, the present application may increase the operation of the compressor by a second preset frequency, and detect the temperature of the IPM after the compressor is operated for a second preset period of time.
S203, if the temperature of the IPM is less than the preset temperature threshold, returning to the step S201 until the temperature of the IPM is not less than the preset temperature threshold and not greater than the preset overtemperature limit.
Specifically, the present application may detect whether the temperature of the IPM is less than a preset temperature threshold after the compressor is operated for a second preset time period according to the frequency after the compressor is lifted, if yes, may lift the compressor operating frequency again and detect whether the temperature of the IPM is less than the preset temperature threshold again after the compressor is operated for the second preset time period until the temperature of the IPM is not less than the preset temperature threshold and is not greater than the preset overtemperature limit.
It is understood that, during the period of increasing the operating frequency of the compressor, if the temperature of the IPM is detected to be greater than the preset over-temperature limit value, the present application may return to step S101, i.e., decrease the operating frequency of the compressor again.
According to the air conditioner operation control method, the operation frequency of the compressor can be increased as much as possible by periodically increasing the operation frequency of the compressor and detecting the temperature of the IPM, the refrigeration efficiency of the compressor is guaranteed, and the user experience is improved while the IPM overtemperature is effectively avoided.
As shown in fig. 3, the present application proposes a third air conditioner operation control method. The method may further comprise, after step S102, the steps of:
s301, recording a target frequency under the condition that the target temperature is not less than a preset temperature threshold value.
Specifically, the present application may record the operating frequency of the compressor, that is, the target frequency, when it is determined that the target temperature is not less than the preset temperature threshold. As shown in fig. 3, when the determination result of determining whether the target temperature is less than the preset temperature threshold is no, the present application may record the target frequency.
S302, controlling the compressor to be in a stop state.
S303, detecting whether the temperature of the IPM is smaller than a preset temperature threshold after the third preset time period, and if not, returning to the step of detecting whether the temperature of the IPM is smaller than the preset temperature threshold after the third preset time period until the temperature of the IPM is detected to be smaller than the preset temperature threshold.
Specifically, the present application may control the compressor to be in a shutdown state and detect whether the temperature of the IPM is less than the preset temperature threshold after the third preset duration, and if not, may continue to detect whether the temperature of the IPM is less than the preset temperature threshold after the third preset duration until the temperature of the IPM is detected to be less than the preset temperature threshold; if so, step S304 may be performed.
S304, after detecting that the temperature of the IPM is smaller than the preset temperature threshold, controlling the compressor to start at the target frequency, and executing the step S104.
Specifically, after detecting that the temperature of the IPM is less than the preset temperature threshold, the present application may control the compressor to start to operate at the target frequency, and then the present application may execute the step S104, that is, step-wise raise the operating frequency of the compressor until the temperature of the IPM is not less than the preset temperature threshold and not greater than the preset overtemperature limit.
The operation control method of the air conditioner can further ensure the refrigerating efficiency of the compressor, improve user experience and simultaneously effectively avoid IPM over-temperature.
As shown in fig. 4, the present application proposes a fourth air conditioner operation control method. The method may comprise, after step S101, the steps of:
s401, controlling the rotating speed of the external fan to be adjusted from the current rotating speed to a target rotating speed; the target rotating speed is obtained by multiplying the current rotating speed by a preset ratio, and the preset ratio is larger than 1.
It should be noted that, the present application may increase the rotation speed of the external fan in proportion after reducing the operation frequency of the compressor, and increase the heat dissipation rate of the IPM, so as to cool the IPM more quickly.
According to the operation control method of the air conditioner, after the operation frequency of the compressor is reduced, the rotation speed of the external fan is increased in proportion, the heat dissipation rate of the IPM is increased, and the IPM is cooled more quickly.
