Detailed description of the invention
In order to be more clearly understood that the above-mentioned purpose of the present invention, feature and advantage, real with concrete below in conjunction with the accompanying drawings
The present invention is further described in detail by mode of executing.It should be noted that in the case of not conflicting, the enforcement of the application
Feature in example and embodiment can be mutually combined.
Elaborate a lot of detail in the following description so that fully understanding the present invention, but, the present invention also may be used
Implementing to use other to be different from other modes described here, therefore, protection scope of the present invention is not limited to following public affairs
The restriction of the specific embodiment opened.
The embodiment of first aspect present invention, proposes the halt control method of a kind of air-conditioner, as in figure 2 it is shown, the present invention
The schematic flow sheet of halt control method of air-conditioner of an embodiment:
Step 202, after receiving halt instruction, obtains the current operating parameter of compressor；
Step 204, it is judged that whether the current operating parameter of compressor is less than or equal to corresponding shutdown threshold；
Step 206, when the current operating parameter judging compressor is less than or equal to corresponding shutdown threshold, controls throttling machine
Structure regulation is preset to the first of present mode of operation and is shut down aperture, and it is out of service after the first preset duration to control compressor.
The halt control method of the air-conditioner that the present invention provides, obtains the current fortune of compressor after receiving halt instruction
Line parameter, compares current operating parameter with corresponding shutdown threshold, if current operating parameter stops less than or equal to corresponding
During machine threshold value, control throttle mechanism regulation and preset shutdown aperture to the first of present mode of operation, and control compressor first
After preset duration out of service, by after receiving halt instruction, it is judged that whether the current operating parameter of compressor meets and stops
Machine condition, and in judged result in the case of being jointly controlling scalable throttle mechanism and compressor, will throttle machine
Structure quickly regulates to the first of present mode of operation to preset shuts down aperture, and after the first preset duration, makes compressor stop fortune
OK, it is to avoid compressor stops suddenly making pressure, flow velocity, flow change suddenly and effect of inertia causes compressor and compressor
Pipe arrangement is shaken, effectively ensure that compressor is less at load, running frequency relatively low in the case of shut down, reduce compressor
The stress of compressor piping during shutdown, and then prevent the stress of compressor piping from exceeding standard, meanwhile, efficiently solve single rotor pressure
Contracting machine is big because of discharge capacity, and compressor is the most out of service to be made compressor serious with the shake of pipe arrangement and affect the problem in pipe arrangement life-span,
It is effectively improved the service life of pipe arrangement, and then improves reliability and the service life of air-conditioner.Further, shutdown refers to
Order can include that the shutdown when instruction of subscriber switch machine, protection halt instruction and indoor temperature reach user's design temperature refers to
Order, and meet other halt instructions required, range is extensive.
As it is shown on figure 3, the schematic flow sheet of the halt control method of the air-conditioner of an alternative embodiment of the invention:
Step 302, after receiving halt instruction, obtains the current operating parameter of compressor；
Step 304, it is judged that whether the current operating parameter of compressor is less than or equal to corresponding shutdown threshold；
Step 306, when judged result is for being, controls throttle mechanism regulation and presets shutdown to the first of present mode of operation
Aperture, and it is out of service after the first preset duration to control compressor；
Step 308, when judged result is no, controls compressor and carries out frequency reducing or unloading, and controls throttle mechanism the
After two preset duration, regulate to the second of present mode of operation to preset and shut down aperture；
Step 310, obtains the current operating parameter of compressor, and is back to step 304.
In this embodiment, if current operating parameter is more than corresponding shutdown threshold, control compressor carry out frequency reducing or
Person unloads, and after the second preset duration, controls throttle mechanism regulation to the second of present mode of operation and preset shutdown aperture, so
The rear current operating parameter continuing to obtain compressor, and rejudge the relation of current operating parameter and corresponding shutdown threshold.Logical
Cross and judge whether the operational factor of compressor meets halt condition, when the current operating parameter of compressor is more than corresponding shutdown threshold
Value, when compressor is unsatisfactory for halt condition, by taking to carry out scalable throttle mechanism and compressor in the regulation control stage
Jointly control, by compressor frequency reducing or unloading, and after the second preset duration, control throttle mechanism and regulate to currently running mould
The second of formula is preset and shuts down aperture, and then makes compressor be rapidly achieved halt condition, carries out according to the action meeting halt condition
Shut down, entrance can stopped status, it is to avoid compressor stops suddenly making pressure, flow velocity, flow change suddenly and effect of inertia
And cause compressor and pipe arrangement acutely to be shaken, make compressor slowly stop, efficiently reducing the stress of pipe arrangement, avoid simultaneously
High frequent start and stop and cause pipe arrangement to occur splitting pipe leakage fluorine or the situation of disconnected pipe, be effectively improved compressor piping and use the longevity
Life, it is ensured that the quality of pipe arrangement, and then improve reliability and the service life of air-conditioner, improve the satisfaction that user uses.
As shown in Figure 4, the schematic flow sheet of the halt control method of the air-conditioner of yet another embodiment of the present invention:
Step 402, after receiving halt instruction, obtains the current operating parameter of compressor；
Step 404, it is judged that whether the current operating parameter of compressor is less than or equal to corresponding shutdown threshold；
Step 406, when the current operating parameter judging compressor is less than or equal to corresponding shutdown threshold, controls throttling machine
