Whether work, whether to confirm system in normal range (NR), after there is coolant leakage, is unlikely to due to high frequent is protected
Compressor is burnt, improves existing control program to a certain extent, realizes higher reliability.
As shown in fig. 7, the flow diagram of the control method of the air conditioner of a specific embodiment according to the present invention.Its
In, which includes compressor, which includes：
Step 702, air conditioner is switched on or continues to run with, and detects the working condition of compressor；
Step 704, when the compressor is shut down, judge whether air conditioner has been turned on high voltage protective；
Step 706, when judge high voltage protective and it is not actuated when, continue to judge whether air conditioner has been turned on low-voltage variation；
Step 708, when judge low-voltage variation and it is not actuated when, detect and judge indoor temperature whether reach temperature setting
Value；
Step 710, when indoor temperature and not up to desired temperature, then directly it is determined as the built-in protection of compressor；
When being judged to protecting built in compressor, step 712, the built-in number of starts protected of recording compressed machine, 1 are executed
In hour, judge whether the number of starts is more than or equal to 2 times；
Step 714, when the number of starts be more than or equal to 2 times, send out fault-signal；
Step 716, when the number of starts is less than 2 times, the built-in protector for controlling compressor automatically resets, and continues to detect
The working condition of compressor；
Step 718, it is to be protected automatically reset after, continue detect compressor working condition.
In this embodiment, by detecting the working condition of compressor, to judge when compressor shuts down, it is possible to understand that
, when the compressor is shut down, the electric current by compressor is zero.In the case of compressor shutdown, it is based on inverse control logic,
Judge whether the built-in protection of compressor works, after determining that air conditioner has been switched on protection built in compressor, recording compressed machine
The number of starts of built-in protection, if in 1 hour, the built-in protection accumulation protection number of compressor is more than or equal to 2 times, then prompts
Air-conditioner system occurs lacking refrigerant failure, needs the operation that can just be switched on after manual maintenance, compressor is avoided to be burnt because frequently protecting
It ruins, realizes that the protection of higher level, the self-protection ability of enhancing air conditioner and compressor when refrigerant leaks improve whole
Machine reliability of operation.
As shown in figure 8, the schematic diagram of computer equipment according to an embodiment of the invention.Wherein, which sets
Standby 1 includes：Memory 12, processor 14 and it is stored in the computer program that can be run on memory 12 and on processor 14,
Processor 14 is used to execute the step of control method such as the air conditioner in above-mentioned any embodiment.
Computer equipment 1 provided by the invention is based on inverse control logic, judges whether the built-in protection of compressor acts as
With, confirm whether air-conditioning system is normal with this, in the case of secondary refrigerant leakage, compressor avoided to be burnt because frequently protecting,
It realizes the protection of higher level, realizes more excellent reliability.
The fifth aspect of the present invention, it is proposed that a kind of computer readable storage medium is stored thereon with computer program, meter
Calculation machine program realizes the step of control method such as the air conditioner in above-mentioned any embodiment when being executed by processor.
Computer readable storage medium provided by the invention is based on inverse control logic, judges that the built-in protection of compressor is
It is no to work, confirm whether air-conditioning system is normal with this, in the case of secondary refrigerant leakage, avoids compressor due to frequently protecting
It burns, realizes more excellent reliability.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
