The top mounted parking air conditioning provides a quiet, stable, and controllable resting environment. Firstly, its operating noise is much lower than the roar and vibration of the vehicle engine idling, usually isolating the noise source outside the roof. The indoor unit operates at a lower decibel level, creating an almost quiet sleeping space for the driver, which is conducive to quickly entering deep sleep. Secondly, it can accurately maintain a suitable indoor temperature (such as around 27 ℃ in summer), avoiding problems such as shallow sleep, frequent dreams, and mid night awakenings caused by high temperatures and stuffiness. It also eliminates noise, mosquitoes, and safety hazards caused by using inferior fans or opening windows for ventilation.
