A kind of central air-conditioning energy-saving system Based Intelligent Control operation methodTechnical field
The present invention relates to a kind of technical field of central air, more particularly to a kind of central air-conditioning energy-saving system Based Intelligent Control fortuneRow method.
Background technology
Increasingly serious with electric energy problem in short supply, power-saving technology has turned into government department, all trades and professions and has paid attention to and push awayIt is high.Central air conditioner system is one of indispensable auxiliary facility of modern building, and the consumption of electric energy is very big, accounts for buildingBuild the 50% of the total power consumption of thing.All it is by maximum load due to central air conditioner system and increases certain surplus design, in ChinaSouthern area, the opening time of annual central air-conditioning is about 10 months or so, and actually in 1 year, full load is run mostMany more than ten days, almost most time loads were run below 70%.The negative of main frame is cooled down in usual central air conditioner systemLotus can automatically adjust load with external elements temperature Change, and the cooling pump matched with cooling main frame can not be adjusted automaticallySection load, is almost in operation under 100% load for a long time, causes the significant wastage of energy, is also degrading the operation ring of central air-conditioningBorder and running quality, automaticity are low, when breaking down, easily central air-conditioning energy-saving system are caused damage.
The content of the invention
It is an object of the invention to overcome central air-conditioning to be in the prior art in a kind of great energy with respect to actual demandWaste, automaticity is low, when breaking down, easily in not enough one kind for providing hurtful to central air-conditioning energy-saving systemCentre air conditioner energy-saving system Based Intelligent Control operation method.
The present invention is achieved through the following technical solutions：A kind of central air-conditioning energy-saving system Based Intelligent Control operation sideMethod, including step is as follows：
（1）Start, open central air-conditioning；
（2）Central air-conditioning enters initialization；
（3）Central air-conditioning Dietary behavior is selected, and the model selection includes automatic mode selection, the choosing of manual process patternSelect, jerk model selection；
（4）Step（3）In the manual process model selection include refrigerating water pump manually, No. two refrigerating water pumps manually,No. three refrigerating water pumps manually, cooling pump manually, No. two cooling pumps manually, No. three cooling pumps manually, frequency converter manually, twoNumber frequency converter manually, No. three frequency converters manually, No. four frequency converters it is manual；
（5）Step（3）In the jerk model selection, system enter jerk pattern after, system stops at once, after stoppingTime delay 1 second, system enters exception handles, and the exception handles includes refrigerating water pump troubleshooting, cools down at failure of pumpReason, frequency converter treatment, No. two frequency converter treatment, No. three frequency converter treatment, a No. four frequency converter treatment；
（6）Step（3）Described in automatic mode selection, if system automatic detection is normal, system enters Starting modeSelection；
As system automatic detection is abnormal, system can be detected in order, and whether power supply instrument system is normal, then detect that water is returnedWhether road system is normal, finally detects whether compressor assembly is normal, then judges whether system is normal, and such as system normally can be automaticInto Starting mode selection；If abnormal detect power supply instrument system again again, then water loop system is detected, finally detection is pressedContracting machine system；
（7）Step（6）Described in Starting mode selection include normal starting and normal stopping；
（8）Step（7）Described in Starting mode selection, when system normally starts, system starts to chilled water cyclic systemSystem detection, time delay 1 second after detection, freezing water circulation system is started, and after starting, freezing water circulation system detects freezing failure and stopsOnly, system stops at once, and system enters step（3）Described jerk pattern；
Time delay 120 seconds, cooling water recirculation system detection is opened, and time delay 1 second after detection, cooling water recirculation system is started,After starting, such as cooling water recirculation system failure, then system enter step（3）Described jerk pattern；Such as cooling water recirculation systemNormally, time delay 30 seconds, fault comprehensive monitoring is opened, time delay 15 seconds, and system is automatically processed into program, if catastrophe failure,System enters step（3）Described jerk pattern；In the event of minor failure, then system gives a warning output, if program oneselfDynamic treatment is normal, detects temperature signal frequency converter frequency output and automatic pump automatically；
（9）Step（7）Described in Starting mode selection, when system normally stops, then load be unloaded to 15%, time delay 5Second, compressor stops machine output, after time delay 5 seconds, cooling pump system-down, and time delay 20 seconds, refrigerating water pump system-down, time delay 5 seconds,Into the step（3）Middle system model selection.
The beneficial effects of the present invention are：Step is reasonable, high degree of automation, save energy, and when breaking down, it is right to be difficultCentral air-conditioning energy-saving system causes damage.

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described further to the present invention：
As shown in figure 1, a kind of central air-conditioning energy-saving system Based Intelligent Control operation method, including step is as follows：
