Denso has developed a cabin air conditioning unit for large trucks, named Everycool, which can be used when a truck’s engine is not running.

Denso said, compared to current systems in Japan, it reduces power consumption by 57% and can be powered using the standard vehicle battery.

Everycool integrates the fan, enabling a single unit to perform the entire heat exchange compared to conventional systems which incorporate separate indoor and outdoor fans.

It uses a small electric compressor.

The new system is 30% smaller and 63% lighter than conventional a/c systems.

The smaller size means there is no obstruction of the rear window, making it suitable for a range of vehicle types, including medium size trucks and tractor trailers.
