Air conditioning compressor for new energy vehicles2023-09-28
Some new energy vehicles are no longer equipped with internal combustion engines, or do not mainly use engines as power sources. Obviously, most compressors for air-conditioning and refrigeration are no longer driven by engines, but are driven by electric motors instead. This driving method eliminates the traditional external drive pulley. The motor is generally assembled with the compressor to form a fully enclosed structure. This structure is easy to operate and can be installed anywhere in the engine room, and the motor and compressor are It can be driven coaxially, and there will be no belt slippage or asynchronous rotation between the compressor speed and the engine speed caused by the traditional drive method.
Since the motor coaxially drives the compressor, the compressor speed can be changed by adjusting the motor speed, achieving flexible control of the air conditioning compressor displacement and cooling capacity. The closed drive structure has only the power cord and the air inlet and outlet pipes connected to the outside. It has high operation reliability and low failure rate.
