At the heart of this revolution lies the dual-rotor compressor technology, which — when paired with R410A refrigerant and IPX7 waterproofing — delivers 43% higher energy efficiency than traditional systems.

The evolution of parking air conditioning systems has reached a critical juncture.

Idle air conditioning systems for commercial trucks, mining vehicles, and RVs face three critical limitations

As global temperatures rise by 1.1°C annually (NOAA 2024), truck cabins now face interior heat spikes exceeding 65°C during parking - a lethal threat to driver safety and cargo integrity.

The transport refrigeration sector faces a dual crisis: 42% of fleet operators report energy waste during idle parking cycles (EPA 2025), while 67% struggle with EU F-Gas Regulation compliance 3.

This article explores how the integration of R410A refrigerant and twin-rotary compressors revolutionizes parking AC performance, with a focus on technical innovation and user-centric design.
