Description
Technical field
This utility model relates to on-board air conditioner field, particularly relates to the air conditioner of electric vehicle with frequency-changing control system.
Background technology
Current integral new-energy passenger is based on electric motor coach, and electric air-conditioning is the important system composition that electric motor coach is indispensable, and when air-conditioning equipment puts into operation, its energy consumption accounts for the 1/5 ~ 1/3 of car load energy consumption, is the electric motor coach second largest energy dissipating portion except drive system.Realizing the industrialization of electric motor coach, solving that the existing continual mileage of electric motor coach is short, battery life is short, cost height Three Difficult Issues, just must conscientiously study the characteristic of air conditioner for electric motor coach, thus developing air conditioner for electric motor coach industry.
Owing to the all-round popularization of electric motor coach just grew up in recent years, in current domestic and international market, air conditioner for electric motor coach technical merit is relatively all relatively low, is usually and train air-conditioning transplanting is improved.Also being typically the air conditioner for electric motor coach of main flow on market at present, substantially indiscriminately imitated the layout design version of train air-conditioning, this small product size is big, heavy, and therefore power consumption is high, and noise is big, and potential safety hazard is big.
Utility model content
The purpose of this utility model is to provide a kind of air conditioner of electric vehicle with frequency-changing control system, reduces power consumption, reduces noise, reduces potential safety hazard.
The technical solution of the utility model is the air conditioner of electric vehicle with frequency-changing control system, described frequency-changing control system includes converter and DC converter, described converter and DC converter connect the high-voltage DC power supply of electric motor car by CAN, described converter connects frequency-changeable compressor and controller respectively, under the control of the controller, converter is by the three-phase alternating current that DC source inversion is voltage and frequency-adjustable, and this three-phase alternating current electric drive frequency-changeable compressor works；Described DC converter connects condensation fan and evaporation fan respectively, provides the unidirectional current of 24V for condensation fan and evaporation fan；Described condensation fan has 4, and the quality of each condensation fan is 2.5kg, and rated voltage is 24V；Described evaporation fan has 8, and the quality of each evaporation fan is 2kg, and rated voltage is 24V.
Controller is automatically adjusted refrigerating capacity according to the change of car internal loading, it is achieved energy-conservation, and equilibrium temperature fluctuates；Flexible start and stop frequency-changeable compressor, reduces starting current, reduces noise, meanwhile, reduces and starts the power supply impact to power supply, also protect compressor.
The alternating current-direct current of frequency-changing control system separately controls, and had both maintained the simple use of system, and turn avoid interference each other.Also reduce the difficulty processing safety coefficient.
Frequency-changing control system carries out data transmission based on the CAN form of automobile itself, and reliability is very high, is very suitable for automotive environment, can carry out resource-sharing and information mutual communication with the CAN module of other system in car simultaneously.Adopt the communication of CAN form, it is also possible to reduce the wire harness of 80% in original air conditioner controlling technology, be substantially reduced wire harness cost, reduce potential safety hazard.
Further, the air quantity of each condensation fan generation is 2400m3/h.Compared to the prior art, under equal air quantity, rotating speed is lower, therefore reduces noise.
Further, the air quantity of each evaporation fan generation is 900m3/h.Compared to the prior art, under equal air quantity, rotating speed is lower, therefore reduces noise.
Further, the air outlet of evaporation fan is provided with vaporizer, and the air outlet of condensation fan is provided with condenser.
Beneficial effect: controller is automatically adjusted refrigerating capacity according to the change of car internal loading, it is achieved energy-conservation, reduces power consumption, and equilibrium temperature fluctuates；Flexible start and stop frequency-changeable compressor, reduces starting current, decreases noise.Adopt the communication of CAN form, it is also possible to reduce the wire harness of 80% in original air conditioner controlling technology, be substantially reduced wire harness cost, reduce potential safety hazard.
