Variable frequency air conditioner system for electric automobile

Abstract

The invention discloses a variable frequency air conditioner system for an electric automobile. The variable frequency air conditioner system comprises a control unit, a refrigeration unit and a heating unit. The control unit comprises a control panel, a harness controller and a controller assembly. The control panel is provided with multiple adjusting knobs and multiple buttons and connected with the harness controller through a harness. The harness controller comprises a current variable frequency adjuster, multiple fuses, multiple relays and corresponding electrical elements. The harness controller is connected with the controller assembly and the heating unit through harnesses. The controller assembly is connected with the refrigeration unit through a harness. The refrigeration unit comprises an evaporation box assembly, a condenser assembly and a compressor. The evaporation box assembly, the condenser assembly and the compressor are connected with one another through pipelines. The heating unit comprises a PTC heater and a PTC current variable frequency adjuster. The PTC current variable frequency adjuster is arranged in the harness controller. The current variable frequency adjuster is used for adjusting the refrigeration amount in a stepless manner.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioners, in particular to an electric vehicle frequency conversion air conditioner system. Background technique [0002] With the continuous development of the automobile industry, the comfort in the car has become a priority when users choose products, and the air-conditioning system in the car plays a vital role in the comfort, but for electric vehicles, if The traditional air conditioning system will not only consume a lot of power and affect the mileage of the car, but also cause damage to the battery and electrical components due to the high current and high power generated during the cooling and heating process, thus affecting the service life of the electric car . [0003] Therefore, developing an air-conditioning system with low power consumption and long service life has become a problem that people in the industry need to solve urgently. Contents of the invention [0004]...
