PCM Pack – Underbody Mounted Type
Hybrid Type
A PCM pack (−21°C) that stores high-density thermal energy is
installed under the vehicle.
The DC compressor is powered by the vehicle battery while driving.
Air is circulated to maintain a refrigeration temperature of 3–5°C,
depending on the type of fresh food being transported.
Cooling energy is stored in the PCM pack installed under the vehicle.

Thermal Storage Refrigerated Vehicle
During operation, refrigeration is provided using the thermal energy stored in the PCM.
Any insufficient cooling energy is supplemented using electricity generated by
the vehicle’s generator while driving to maintain the temperature.

PCM Smart Refrigerated Truck Advantages &
Field Performance Test
A comparative test was conducted using currently operating 1-ton logistics vehicles
(ICOOP standard delivery vehicle vs. PCM vehicle).
Through two rounds of testing (same driver assigned),
an approximate 20% improvement in fuel efficiency was directly confirmed.
