Air_Conditioning_system练习

BeckhoffBuildingAutomation09.06.20201,NewAutomationTechnology,NewAutomationTechnology,HVAC-LibraryExerciseAirConditioningSystem,BeckhoffBuildingAutomation09.06.20202,AirConditioningSystem包括1SpeedFans,AirHeating,AirMixingandAirCooling.房间温度由冷（热）源温温度PID和房间温度PID串级控制。冷热源温度受主控制器限定。如果检测到冻结风扇就会停止，加热阀就会打开，热泵就会启动。系统有夏夜制冷,过冷保护，过热保护.如果加热阀开启超过3%热泵就启动。泵和加热阀需要有防堵转保护。可以根据日程表调整运行时间，日程表包括节假日。,HVAC-LibraryExerciseAirConditioningSystem,BeckhoffBuildingAutomation09.06.20203,SupplyAir,Y,cooling,Mixing,heating,T,T,T,2,T,room,Mixing,Sw,3,2,1,otret_T,T,3,Heizen,HVAC-LibraryExerciseAirConditioningSystem,BeckhoffBuildingAutomation09.06.20204,ProgrammingStep1(creatingplantfolder),在导入宏之前先建立一个项目文件夹.,HVAC-LibraryExerciseAirConditioningSystem,BeckhoffBuildingAutomation09.06.20205,下一步从文件夹:EXP_FilesGroups导入组步骤:用记事本打开文件重命名项目名存盘导入宏,ProgrammingStep2(importingmacros),HVAC-LibraryExerciseAirConditioningSystem,AC02,AC02,AC01,BeckhoffBuildingAutomation09.06.20206,下列组和子程序都必须导入:Main程序：MAINPROGAM_AIR_CONDITIONING.EXP温度传感器AC-Plant:TEMPERATURE_SONSORS_AC_PLANT.EXP送回风扇:FANS_1SPEED_Ventilation_Air_Conditioning.EXP通过PID和夏季补偿进行温度设定计算:SetpointcalculationforRoomandSupplyTemperaturecascade.EXPCoolerwithPID和阀门控制:COOLER.EXP.EXP利用风门进行空气PID调节:AIRMIXING.EXPAC-Plant启动程序:X_StartAC送回风空气过滤:FilterGuard_X_Filter.EXP报警记录AC-PlantERRORCOLLECTION_AC.EXP,ProgrammingStep2(importingmacros),HVAC-LibraryExerciseAirConditioningSystem,BeckhoffBuildingAutomation09.06.20207,热源空气预加热PID,回水温度PID,热泵和防冻结程序:PREHEATER.EXP防过冷程序Cooling_Down_Protection_X_CoolDownProtection.EXP带手动控制的计划控制程序TIMESCHEDULING_1STAGE_CMDCTRL_1STAGE_X_TIMESCHEDUL2ST_CMDCTRL2ST.EXP夏夜制冷程序SummerNightCooling_X_NightCooling.EXP防过热程序OverheatingProtection_X_OverHeatProtec.EXP,ProgrammingStep2(importingmacros),HVAC-LibraryExerciseAirConditioningSystem,BeckhoffBuildingAutomation09.06.20208,导入宏之后目录列表如下,ProgrammingStep2(importingmacros),HVAC-LibraryExerciseAirConditioningSystem,BeckhoffBuildingAutomation09.06.20209,AC01调用所有的子程序,ProgrammingStep3(callfromallsubprograms),HVAC-LibraryExerciseAirConditioningSystem,BeckhoffBuildingAutomation09.06.202010,AC01检查是否所有的程序都被正确调用,ProgrammingStep4(callfromallsubprograms),HVAC-LibraryExerciseAirConditioningSystem,BeckhoffBuildingAutomation09.06.202011,ProgrammingStep4(callfromallsubprograms),HVAC-LibraryExerciseAirConditioningSystem,AC01检查是否所有的程序都调用完成.,BeckhoffBuildingAutomation09.06.202012,MAIN必须调用AC01,ProgrammingStep5(callfromAC01inMAIN),HVAC-LibraryExerciseAirConditioningSystem,BeckhoffBuildingAutomation09.06.202013,compile,download,connectionwiththeterminals,ProgrammingStep6(compiling),HVAC-LibraryExerciseAirConditioningSystem,BeckhoffBuildingAutomation09.06.202014,练习2:添加第二个空调系统:步骤:导出AC01到文件夹重命名AC01为AC02,存盘，导入IncludeanAir/AirHeatexchangerintotheAC02.AdjusttheSequencecontroller(currentsequence,numberofsequences)AdthecallfromtherecoverysysteminAC02MAIN中调用AC02Afterthisprocedureprogrammingasecondplantwitharecoverysystemisdone!,Exercise2(ProgramminganadditionAC),HVAC-LibraryExercisesAirConditioningSystem,BeckhoffBuildingAutomation09.06.202015,AdditionalExercise:AdathirdAirConditioningplant:Procedure:ExportyourAC02totheExport-FolderplantsRenameAC02toAC03,saveandimportDeletethefolderEnergyRecoveryIncludeanrecuperationheatexchangerintotheAC03.AdjusttheSequencecontroller(currentsequence,numberofsequences)Adthecall
