Detailed description of the invention
In order to be better understood from this utility model, illustrate with embodiment below in conjunction with the accompanying drawings.In description of the present utility model, it should be noted that term " first ", " second " etc. are only used for describing purpose, and it is not intended that indicate or hint relative importance.
Embodiment: as shown in Figure 1 and Figure 2, a kind of Automatic Cycle starts off-premises station, including the first off-premises station and the second off-premises station, each off-premises station is divided into plenum chamber and Machine Room, heat exchanger 4 and fan 5 are installed in plenum chamber, being provided with two compressors and electric-control system 3 etc. in Machine Room, in the first off-premises station, two compressors are respectively the first compressor 1 and the second compressor 2.Plenum chamber and Machine Room separately can effectively prevent electric-control system 3 and other vitals by rain erosion, increase the service life of off-premises station.Described electric-control system 3 includes main control module, calculates the timing module running the time after each compressor single is started shooting, and drives the first driving module of the first compressor 1 and the second driving module of the second compressor 2 respectively.Module is driven to receive the control instruction of main control module and drive corresponding compressor operating, timing module is added up the operation time of each compressor and is transferred to main control module, main control module receiving time information also calculates accumulated running time of each compressor, controls to drive module to open accumulated running time short compressor after contrast.Such as, during start, multi-gang air-conditioner is according to the demand of opened indoor set, open one or more compressor, now four compressors are run the statistics of time by controller according to timer, and calculate accumulated running time, select the preferential startup optimization of compressor that the cumulative time is short.The duration of runs and the operating frequency that so make four compressors are of substantially equal, are prevented effectively from certain compressor or the excessive situation of module workload, reduce fault rate, improve system stability, extension device service life.
When one of them compressor (such as the first compressor of the second off-premises station) breaks down, respective drive module will detect fault, major failure includes: compressor frequency abnormal (compressor step-out), compressor overcurrent fault, compressor overvoltage fault etc., so rear drive module sends, with the form of failure code, the fault detected to main control module, and main control module just can determine that this compressor breaks down after receiving failure code.When next time, off-premises station started, other three compressors of master control module controls are operated, thus ensure that multi-connected machine runs well.Without manually arranging, intelligent and safe.
