Description
Technical field
The present invention relates to the air-conditioning technique field of air-conditioning equipment, specifically a kind of conditioner that can meet direct current 270V and 26V power supply.
Background technology
270V HVDC is because its efficiency is high, reliability is high, the plurality of advantages such as lightweight becomes following electric-control system and to power the preferred option of system, current many special cars have adopted the hybrid power supply of 270V and 26V power supply, to be eager this kind of power supply mode, how under 270V HVDC powers system, to realize the technology such as refrigeration, new requirement is proposed to conditioner, what conditioner adopted is that vapor-compression type realizes refrigeration, electrically driven (operated) parts are needed to have compressor, evaporation fan, condensation fan, compressor need use direct current 270V power drives, evaporation fan and condensation fan need use 26V.Direct current 270V power drives directly used by usual domestic employing motor compressor, and the conditioner little to refrigerating capacity can realize, and cannot realize larger refrigerating capacity device, but this kind type of drive efficiency is low, reliability is low.
Summary of the invention
The object of the invention is the disappearance for prior art, provide a kind of structure simple, easily implement, equipment and component count is less, efficiency is high, easy to maintenance, the efficient conditioner that can meet direct current 270V and 26V power supply.
Technical scheme of the present invention is as follows:
A kind of conditioner that can meet direct current 270V and 26V power supply, include refrigeration system, ventilating system and electric-control system, it is characterized in that: described refrigeration system includes the compressor, condenser and the evaporimeter that are connected successively, described ventilating system includes evaporation fan and condensation fan, and described electric-control system includes direct current 270V power supply, direct current 26V power supply, power supply changeover device, control system and protection system; Described direct current 270V power supply is connected by the power input of described power supply changeover device with described compressor, and described direct current 26V power supply is connected with the power input of condensation fan with described evaporation fan respectively; Described protection system includes the temperature sensor being arranged at air-conditioning equipment indoor return air place, and described temperature sensor is electrically connected with described compressor by described control system.
The described conditioner that can meet direct current 270V and 26V power supply, is characterized in that: described compressor adopts DC frequency-changeable compressor.
Beneficial effect of the present invention:
Structure of the present invention is simple, is easy to manufacture, and cost is low, and efficiency is high, easy for installation, failure rate is low, and reliability is high, easy to maintenance, achieves frequency conversion soft start and to driven compressor, can effective implemention air conditioning; In addition, can available protecting refrigeration system, save the energy.
Accompanying drawing explanation
Fig. 1 is structural principle block diagram of the present invention.
Detailed description of the invention
See Fig. 1, a kind of conditioner that can meet direct current 270V and 26V power supply, include refrigeration system, ventilating system and electric-control system, refrigeration system includes the DC frequency-changeable compressor 1, condenser and the evaporimeter that are connected successively, ventilating system includes evaporation fan 2 and condensation fan 3, and electric-control system includes direct current 270V power supply 4, direct current 26V power supply 5, power supply changeover device 6, control system 7 and protection system; Direct current 270V power supply 4 is connected by the power input of power supply changeover device 6 with DC frequency-changeable compressor 1, and direct current 26V power supply 5 is connected with the power input of evaporation fan 2 with condensation fan 3 respectively; Protection system includes the temperature sensor 8 being arranged at air-conditioning equipment indoor return air place, and temperature sensor 8 is electrically connected with DC frequency-changeable compressor 1 by control system 7.
Below in conjunction with accompanying drawing, the present invention is further illustrated:
Direct current 270V power supply 4 is first boosted by power supply changeover device 6 and carries out DC pulse process to it again, exports pulse variable-frequency power sources and drives DC frequency-changeable compressor 1, realize frequency conversion soft start and the driving to DC frequency-changeable compressor 1.Evaporation fan 2, condensation fan 3 adopt direct current 26V power supply 5 to power.
The temperature at temperature sensor 8 Real-Time Monitoring air-conditioning equipment indoor return air place, and feed back to control system 7, control system 7 is compared automatically by the temperature of return air temperature and setting, when return air temperature is higher than design temperature, DC frequency-changeable compressor 1 and outdoor fan operate simultaneously, and refrigeration system is started working; When return air temperature reaches design temperature, DC frequency-changeable compressor 1 quits work, and refrigeration system quits work, and indoor fan works on ventilation.
Claims (2)
1. one kind can meet the conditioner of direct current 270V and 26V power supply, include refrigeration system, ventilating system and electric-control system, it is characterized in that: described refrigeration system includes the compressor, condenser and the evaporimeter that are connected successively, described ventilating system includes evaporation fan and condensation fan, and described electric-control system includes direct current 270V power supply, direct current 26V power supply, power supply changeover device, control system and protection system; Described direct current 270V power supply is connected by the power input of described power supply changeover device with described compressor, and described direct current 26V power supply is connected with the power input of condensation fan with described evaporation fan respectively; Described protection system includes the temperature sensor being arranged at air-conditioning equipment indoor return air place, and described temperature sensor is electrically connected with described compressor by described control system.
