Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, an embodiment of the present invention provides a quick start control device 10 for an air conditioner compressor, which is applied to an air conditioner 100. The air conditioner 100 includes a quick start control device 10 and a controller 20 of an air conditioner compressor. The quick start control device 10 of the air conditioner compressor includes at least one software function module which can be stored in the controller 20 in the form of software or firmware (firmware) or solidified in an Operating System (OS) of a server. The controller 20 is used for executing executable modules stored therein, such as software functional modules and computer programs included in the quick start control device 10 of the air conditioner compressor.
The controller 20 may be an integrated circuit chip having signal processing capabilities. The controller 20 may be a general-purpose Processor, and includes a Central Processing Unit (CPU), a Network Processor (NP), and the like; but may also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other programmable logic device, discrete gate or transistor logic device, discrete hardware components. The various methods, steps and logic blocks disclosed in the embodiments of the present invention may be implemented or performed. A general purpose processor may be a microprocessor. The controller 20 may also be any conventional processor or the like.
The controller 20 records a quick start control program of the air conditioner compressor, and after receiving the execution instruction, the controller 20 executes the quick start control program of the air conditioner compressor and realizes the quick start control method of the air conditioner compressor.
Referring to fig. 2, a method and an apparatus for controlling a quick start of an air conditioner compressor and a method for controlling an air conditioner 100 according to an embodiment of the present invention include the following steps.
Step S100: and controlling the compressor to start reversely under the condition that the normal start of the compressor fails.
It should be noted that there may be various reasons for the air conditioner compressor failing to start normally, such as overcurrent. The method for controlling the quick start of the compressor provided by the embodiment of the invention can be applied to the restart of the compressor in a short time after the shutdown, and the start speed of the compressor is increased. Meanwhile, it should also be noted that the compressor has a large pressure difference between the air inlet and the air outlet when it is operated, the pressure difference is still large in a short time after the shutdown, and when the compressor is normally started again, a large resistance torque exists.
In the embodiment of the invention, the short time after the shutdown refers to the time when the resistance torque of the pressure difference between the air inlet and the air outlet of the compressor is larger and the normal startup of the compressor is influenced. For example, for some models of compressors, the short time after shutdown is within three minutes; namely, the compressor can not be normally started within three minutes after the compressor is stopped, and the pressure of an air inlet and an air outlet of the compressor can be basically restored to be balanced by waiting about three minutes; that is, the pressure difference between the inlet and outlet ports of the compressor may cause the normal start-up failure of the compressor within three minutes after the compressor is stopped.
In the embodiment of the invention, if the compressor fails to be started normally, the compressor is controlled to reversely rotate so as to quickly balance the pressure difference between the air inlet and the air outlet of the compressor and realize the quick restart of the compressor in a short time after the shutdown. It is also noted that for a single rotor compressor, the reverse rotation is not possible during normal operation. The long-time reverse running can cause the lubricating fluid of the thrust shaft of the compressor to be lost, and the service life is reduced. In this case, in the step S100, when the operation is stopped and then rapidly restarted, the lubricant is not lost in the reverse operation with a short time and a low power, and the service life of the compressor is hardly affected. That is, in order to shorten the start time and actively balance the pressure of the external pipe, the compressor may be reversely rotated, so that the refrigerant in the high pressure region may be circulated to the low pressure region, thereby accelerating the process of pressure balance of the pipe.
Step S200: and acquiring a normal starting judgment parameter of the compressor.
It should be noted that the normal start judgment parameter of the compressor refers to a parameter that the compressor can be started normally, and is mainly used for reflecting a pressure difference between an intake port and an exhaust port of the compressor or a resistance torque corresponding to the pressure difference. The normal starting judgment parameter of the compressor can be the pressure at the air inlet and the air outlet of the compressor, and can also be the torque current of the compressor. Or other parameters which can reflect the pressure difference between the air inlet and the air outlet of the compressor or the resistance torque corresponding to the pressure difference, etc., the embodiment of the present invention does not make specific requirements and limitations on the specific types of the normal start-up judgment parameters of the compressor.
Step S300: and judging whether the normal starting judgment parameter of the compressor is in a preset range.
Step S400: and if the normal starting judgment parameter of the compressor is in the preset range, controlling the compressor to stop firstly and then start normally.
It should be noted that, if the normal start judgment parameter of the compressor is within the preset range, it indicates that the compressor can be started normally or the compressor can overcome the resistance torque corresponding to the pressure difference. That is, when the normal start judgment parameter of the compressor is within the preset range, the compressor can be normally started. At this time, the compressor is controlled to stop first, even if the compressor stops reversing first, and then the compressor is controlled to start normally, so that the compressor can be started quickly in a short time after the stop.
Referring to fig. 3, in an alternative embodiment, step S100 may include the following sub-steps: substep S110: acquiring the reverse starting times of the compressor under the condition that the normal starting of the compressor fails; substep S120: if the reverse starting times of the compressor is less than one time, controlling the compressor to start reversely; substep S130: otherwise, the start failure flag is set.
It should be noted that, in the case that the normal start of the compressor fails, if the compressor has been started in the reverse direction, it is indicated that the reason why the compressor cannot be started normally is not the pressure difference between the air inlet and the air outlet of the compressor, but other reasons, and at this time, the start failure flag may be set, so as to determine whether the compressor has a fault in the subsequent steps. When the reverse starting frequency of the compressor is less than one time, namely the compressor is not started reversely, the compressor is controlled to start reversely so as to quickly balance the pressure difference of the air inlet and the air outlet of the compressor and achieve the effect of quick starting.
In an alternative embodiment, in the step of controlling the compressor to start in reverse, the motor of the compressor is controlled to rotate in reverse with respect to the direction of normal start.
In an alternative embodiment, the normal start-up determining parameter of the compressor includes a torque current of the compressor, and at this time, the step S300 may include: and judging whether the torque current of the compressor is smaller than a preset current, wherein the preset current is a set percentage of a preset maximum current when the compressor is normally started. And if the torque current of the compressor is smaller than the preset current, controlling the compressor to stop firstly and then start normally.
In an alternative embodiment, the normal start-up determining parameter of the compressor includes a pressure difference of the compressor, and in this case, the step S200 includes: acquiring the pressure of an exhaust port and the pressure of an air inlet of a compressor; the differential pressure of the compressor is calculated based on the discharge port pressure and the intake port pressure of the compressor. Step S300 includes: and judging whether the pressure difference of the compressor is smaller than a preset pressure difference. And if the pressure difference of the compressor is smaller than the preset pressure difference, controlling the compressor to stop firstly and then start normally.
The embodiment of the invention provides a quick start control method of an air conditioner compressor, which comprises the following steps: if the compressor fails to start normally, the compressor is controlled to rotate reversely so as to quickly balance the pressure difference between the air inlet and the air outlet of the compressor and realize quick restart of the compressor in a short time after shutdown. And judging whether the compressor can be normally started or not according to the normal starting judgment parameter of the compressor, and controlling the compressor to be normally started when the compressor can be normally started. In the embodiment of the invention, the pressure difference between the air inlet and the air outlet of the compressor can be quickly balanced through the reverse rotation of the compressor, so that the restarting speed of the compressor in a short time after the shutdown is facilitated, and the user experience is improved.
