Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
See Fig. 1; a kind of conditioner adapting to DC520V power supply; include refrigeration system, ventilating system and electric-control system; refrigeration system includes compressor 1, condenser 2, dry liquid storage filter 3, expansion valve 4 and the vaporizer 5 being sequentially connected; ventilating system includes condensation fan 7 and evaporation fan 6, and electric-control system includes DC520V power supply 8, power supply changeover device 9, control unit 10 and protection system；DC520V power supply 8 is connected by the power input of control unit 10 with compressor 1, DC520V power supply 8 is connected by the input of control unit 10 with power supply changeover device 9, the outfan of power supply changeover device 9 by control unit 10 respectively power input with condensation fan and 7 evaporation fans 6 be connected；Protection system includes the temperature sensor being arranged at air-conditioning equipment indoor return air, and temperature sensor is electrically connected with compressor 1 by control unit 10.
In the present invention, DC520V power supply 8 exports direct current 520V power supply to compressor 1.
Power supply changeover device 9 goes out direct current 24V power supply by control unit 10 to condensation fan defeated 7.
Power supply changeover device 9 exports direct current 270V power supply by control unit 10 to the solidifying blower fan 6 of evaporation.
Below in conjunction with accompanying drawing, the present invention is further illustrated:
Direct current 270V power supply carries out DC pulse process by control unit 10, and output pulse variable-frequency power sources drives compressor 1, it is achieved the frequency conversion soft start of compressor 1.Condensation fan 7 and evaporation fan 6 are respectively adopted direct current 24V power supply and direct current 270V power supply is powered.
The temperature at air-conditioning equipment indoor return air is monitored in temperature sensor in real time, and feeding back to control unit 10, control unit 10 is compared automatically by the temperature of return air temperature with setting, when return air temperature is higher than design temperature, compressor 1 and outdoor fan operate simultaneously, and refrigeration system is started working；When return air temperature reaches design temperature, compressor 1 quits work, and refrigeration system quits work, and indoor fan works on ventilation.
Control unit 10, according to the temperature set, pressure, the status signal of input signal, determines that the running status to compressor 1, condensation fan 7 and evaporation fan 6 controls.
