Description
Technical field
This utility model relates to the air-conditioning technique field of air-conditioning equipment, 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 powers the preferred option of system, the most many special cars have used 270V and 26V power supply hybrid power supply, it is eager this kind of power supply mode, how under 270V HVDC powers system, to realize the technology such as refrigeration, conditioner is proposed new requirement, conditioner uses vapor-compression type and realizes refrigeration, electrically driven (operated) parts are needed to have compressor, evaporation fan, condensation fan, compressor need to use direct current 270V power drives, evaporation fan and condensation fan need to use 26V.Usual domestic employing motor compressor directly by direct current 270V power drives, the conditioner little to refrigerating capacity it is achieved that bigger refrigerating capacity device cannot be realized, but this kind type of drive efficiency is low, reliability is low.
Utility model content
The purpose of this utility model is the disappearance for prior art, it is provided that a kind of simple in construction, easily implement, equipment and component count is less, efficiency is high, the conditioner that can meet direct current 270V and 26V power supply easy to maintenance, efficient.
The technical solution of the utility model 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 compressor, condenser and the vaporizer being sequentially connected; 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 power input with described evaporation fan and condensation fan respectively is connected；Described protection system includes the temperature sensor being arranged at air-conditioning equipment indoor return air, and described temperature sensor is electrically connected with described compressor by described control system.
Described can meet direct current 270V and the conditioner of 26V power supply, it is characterised in that: described compressor uses DC frequency-changeable compressor.
The beneficial effects of the utility model:
This utility model simple in construction, it is easy to manufacture, low cost, efficiency is high, easy for installation, failure rate is low, and reliability is high, easy to maintenance, it is achieved that frequency conversion soft start and to driven compressor, it is possible to efficiently realize air regulation；It addition, refrigeration system can effectively be protected, save the energy.
Accompanying drawing explanation
Fig. 1 is this utility model structural principle block diagram.
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 DC frequency-changeable compressor 1, condenser and the vaporizer being sequentially connected; 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 power input with evaporation fan 2 and condensation fan 3 respectively is connected；Protection system includes the temperature sensor 8 being arranged at air-conditioning equipment indoor return air, and temperature sensor 8 is electrically connected with DC frequency-changeable compressor 1 by control system 7.
Below in conjunction with accompanying drawing, this utility model is further described:
Direct current 270V power supply 4 is first boosted by power supply changeover device 6 and again it is carried out DC pulse process, and output pulse variable-frequency power sources drives DC frequency-changeable compressor 1, it is achieved frequency conversion soft start and the driving to DC frequency-changeable compressor 1.Evaporation fan 2, condensation fan 3 use direct current 26V power supply 5 to be powered.
The temperature at air-conditioning equipment indoor return air is monitored in temperature sensor 8 in real time, and feed back to control system 7, control system 7 is compared automatically by the temperature of return air temperature with 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. the 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 compressor, condenser and the vaporizer being sequentially connected; 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 power input with described evaporation fan and condensation fan respectively is connected；Described protection system includes the temperature sensor being arranged at air-conditioning equipment indoor return air, and described temperature sensor is electrically connected with described compressor by described control system.
