The starting control method of the compressor is applied to an air conditioner, and the air conditioner is installed in an automobile and used for adjusting the ambient temperature of the automobile.
The technical scheme provided by the embodiment of the application is further described below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for controlling start of a compressor according to an embodiment of the present application. The starting control method of the compressor is applied to the air conditioner, the air conditioner comprises a controller and the compressor, the controller is arranged on the air suction side of the compressor, and the controller is arranged on the air suction side of the compressor to effectively dissipate heat and ensure long-term stable and safe operation of the controller due to the fact that the compressor has the characteristics of low temperature of the air suction side and high temperature of the air discharge side. The start-up control method of the compressor is performed by the air conditioner or a processor in the readable storage medium, and includes steps S100, S200, S300, and S400.
Step S100, a first temperature of a circuit board of the controller and a second temperature of the power tube are obtained.
In one embodiment, the circuit board of the controller is provided with temperature sensors, and the power tube is also provided with temperature sensors, wherein the number of the temperature sensors is at least two. Under the condition that two sensors are arranged, reading a first temperature of the sensor on the circuit board and a second temperature of the sensor on the power tube; in the case of setting more than two sensors, the average temperature of the sensors on the reading circuit board is a first temperature, and the average temperature of the sensors on the power tube is a second temperature. The first temperature and the second temperature can reflect the temperatures of different parts of the controller, accurately detect the temperature of the controller, and identify the temperature source.
And step S200, obtaining a control temperature according to the first temperature and the second temperature.
In an embodiment, according to the detected first temperature and second temperature, the higher temperature of the first temperature and the second temperature is used as the control temperature, so that the safe starting of the compressor is controlled according to the control temperature. The calculation formula of the control temperature is expressed as: tboard = max (Tigbt, tpcb), where Tboard is denoted as control temperature, tpcb is denoted as first temperature, tigbt is denoted as second temperature, max () is a maximum function.
Step S300, comparing the control temperature with a preset first temperature threshold, a preset second temperature threshold and a preset third temperature threshold to obtain a first comparison result.
In an embodiment, the first comparison result is obtained by comparing the control temperature with the first temperature threshold, the second temperature threshold and the third temperature threshold, so that the control temperature can be obtained within a corresponding area range, and the subsequent execution of corresponding operations is facilitated to ensure safe starting. The first comparison result includes the following three cases, respectively: the control temperature is less than or equal to a first temperature threshold; the control temperature is greater than the first temperature threshold and less than the second temperature threshold; the control temperature is greater than or equal to the second temperature threshold and less than the third temperature threshold. In the actual scenario, the control temperature is hardly greater than the third temperature threshold, and when the control temperature is greater than the third temperature threshold, the controller of the air conditioner is not started at this time in order to ensure safety. Wherein the first temperature threshold may be 85 ℃, the second temperature threshold may be 90 ℃, and the third temperature threshold may be 125 ℃.
Step S400, the current state of the compressor is obtained, and the starting state of the compressor is determined according to the first comparison result, the current state, the first temperature and the second temperature so as to control the starting of the compressor.
In an embodiment, the current state of the compressor may be obtained by observing an indicator light, the indicator light being on and the compressor being on, the indicator light being off and the compressor being off. The current state of the compressor is obtained, so that the starting state is determined according to the current temperature. And determining the starting state of the compressor according to the first comparison result, the current state, the first temperature and the second temperature so as to control the starting of the compressor, ensure that the controller can be safely started at a higher temperature, and further play a role in regulating the environmental temperature.
As shown in fig. 2, the starting state of the compressor is determined according to the first comparison result, the current state, the first temperature and the second temperature, including but not limited to the following steps:
in step S410, a difference between the second temperature and the first temperature is calculated to obtain a calculation result.
In some possible embodiments of the present application, in a practical situation, the temperature of the power tube is generally greater than or equal to the temperature of the circuit board, and the calculated result obtained by subtracting the first temperature from the second temperature may be greater than or equal to 0. The first temperature may be subtracted from the second temperature to obtain an absolute value, thereby obtaining a calculation result. The method is beneficial to determining the starting state of the compressor by using the calculation result later so as to ensure that the controller can be started safely at a higher temperature.
Step S420, determining the starting state of the compressor according to the first comparison result, the current state and the calculation result.
As shown in fig. 3, the starting state of the compressor is determined according to the first comparison result, the current state and the calculation result, including but not limited to the following steps:
Step S421, comparing the calculated result with a preset fourth temperature threshold value to obtain a second comparison result when the current state is the shutdown state and the first comparison result is that the control temperature is greater than the preset first temperature threshold value and less than the second temperature threshold value.
In some possible embodiments of the present application, when the current state is a shutdown state and the first comparison result is that the control temperature is greater than a preset first temperature threshold and less than a second temperature threshold, it indicates that the control temperature is in a range relatively higher than a normal temperature, and protection is required when the compressor or the controller is started, the calculation result is compared with a preset fourth temperature threshold to obtain a second comparison result, so that the subsequent determination of the startup state according to the second comparison result is facilitated, and safe startup of the controller at a higher temperature is ensured.
In step S422, if the second comparison result is that the calculation result is smaller than the preset fourth temperature threshold, the start state is determined to be start.
In some possible embodiments of the present application, when the second comparison result is that the calculation result is smaller than the preset fourth temperature threshold, it indicates that the first temperature of the circuit board is not much different from the second temperature of the power tube, the compressor may start to operate, and the starting state is determined to be starting, so that safe starting can be achieved, and environmental temperature adjustment can be performed.
In step S423, if the second comparison result is that the calculation result is greater than or equal to the fourth temperature threshold, the start-up state is determined to be the start-up prohibition state.
In some possible embodiments of the present application, when the second comparison result is that the calculation result is greater than or equal to the fourth temperature threshold, it indicates that the first temperature of the circuit board is too different from the second temperature of the power tube, and the startup state is determined to be prohibited to start due to the arrangement of the over-temperature protection, so as to avoid the damage of the air conditioner. The preset fourth temperature threshold value is 10 ℃.
As shown in fig. 4, the starting state of the compressor is determined according to the first comparison result, the current state and the calculation result, including but not limited to the following steps:
In step S424, when the current state is the compressor on state and the first comparison result is that the control temperature is greater than the preset first temperature threshold and less than the second temperature threshold, the calculation result is compared with the preset fourth temperature threshold to obtain a third comparison result.
In some possible embodiments of the present application, in the case that the current state is the compressor on state and the first comparison result is that the control temperature is greater than the preset first temperature threshold and less than the second temperature threshold, it is indicated that the control temperature is in a range relatively higher than the normal temperature, although the current state is the compressor on state, in order to avoid damage to components caused by the excessive temperature, protection is also required for the compressor or the controller. And comparing the calculated result with a preset fourth temperature threshold value to obtain a third comparison result, which is beneficial to determining the starting state according to the third comparison result so as to ensure that the controller can safely operate at a higher temperature.
In step S425, if the third comparison result is that the calculation result is greater than or equal to the fourth temperature threshold, the startup state is determined to be shutdown protection.
In some possible embodiments of the present application, when the third comparison result is that the calculation result is greater than or equal to the fourth temperature threshold, it indicates that the first temperature of the circuit board and the second temperature of the power tube differ too much, and the open state of the compressor continues to have a potential safety hazard, and the start state is determined to be in shutdown protection, so as to avoid damage to components.
In an embodiment, after comparing the calculation result with the preset fourth temperature threshold value to obtain the third comparison result, the start control method of the compressor further includes, but is not limited to, the following steps:
In step S426, when the third comparison result is that the calculation result is smaller than the preset fourth temperature threshold, the running time of the compressor on state is compared with the preset first time threshold, and when the running time is smaller than or equal to the preset first time threshold, the starting state is determined to be the state of keeping the compressor on.
