This invention relates to a method for retrofitting a commercial vehicle's belt-driven air conditioning system to a dual-mode system, addressing the problems inherent in the current market's primary "dual-system parallel" approach for handling vehicle parking cooling needs. The steps include: (a) removing the original belt-driven compressor from the vehicle's air conditioning system while retaining other components; (b) embedding a permanent magnet synchronous motor drive module, enabling the compressor to switch to AC power drive mode when the engine is off, thus forming a dual-mode compressor capable of both belt and electric drive; connecting it in series with the original air conditioning components to form an air conditioning circuit; (c) providing an electric drive controller and wiring harness, the controller converting AC power into the required voltage to power the dual-mode compressor and the original vehicle air conditioning system; and (d) electrically matching the wiring harness with the original vehicle air conditioning wiring harness and allowing for external AC power connection. This invention achieves seamless switching of the air conditioning system between driving and parking conditions through the dual-mode drive retrofit of the belt-driven air conditioning system.
