The parking air conditioning system is a standalone temperature control system specifically designed to maintain a comfortable cabin environment after the vehicle is turned off. Unlike traditional driving air conditioning, it operates independently without relying on engine power, utilizing a dedicated power module for independent operation. This system primarily addresses the temperature control needs of long-haul drivers during parking breaks, eliminating fuel waste and mechanical wear caused by prolonged engine idling for air conditioning use. Its temperature regulation range can typically be precisely controlled between 18°C and 30°C, with some high-end models also featuring humidity adjustment functions to create a truly comfortable rest environment for drivers and passengers
