Hino and DENSO Jointly Develop the World's First Electric Refrigerator System
for Heavy-duty Trucks Using a Hybrid Unit 
Kariya, Japan, Jan 29, 2014 - (JCN Newswire) -  Hino Motors, Ltd. (Hino) and
DENSO Corporation (DENSO) have jointly developed the world's first
electric refrigerator system for heavy-duty trucks using a hybrid unit. This
system is used in the Hino Profia, which will be released on Feb. 1, in Japan. 
With the combination of Hino's hybrid powertrain system technology and
DENSO's electric refrigerator system technology, the two companies have
developed a high-quality refrigerator system that helps improve fuel economy,
improves refrigeration performance, and is quieter when operating. 
Hybrid trucks conventionally use energy generated from hybrid systems to
assist the vehicle's driving. However, this new truck uses energy from
hybrid unit only for the new electric refrigeration system, which saves fuel. 
Heavy-duty refrigerated trucks typically require an auxiliary engine or need
to use their main engine power to operate the compressor of the refrigerator.
The newly developed electric refrigerator system uses energy generated while
driving or regenerated energy from the hybrid unit to operate the
refrigerator's compressor. This substantially reduces the amount of fuel
normally used to drive the engine to operate the compressor, thus reducing CO2
emissions as well. 
Compared to refrigerated trucks that use an auxiliary engine to operate the
compressor, the new system is quieter, and contributes to an approximately
150kg weight reduction because it does not need an auxiliary engine. 
In addition, compared with those having the main engine-driven compressor
system, the new truck can operate the refrigeration compressor at a constant
rotational speed using the energy supplied from hybrid system, which stabilizes
the refrigeration performance and quality regardless if the truck is moving or
Trucks with main engine-driven compressor systems need to have separate
refrigerator components in the engine compartment, under the floor panel, and
in other places. However, the new truck uses a new integrated refrigeration
unit that includes an electric compressor, condenser, and other devices. This
simplified structure uses fewer tubes and wires and also is easier to
The new refrigerator system includes a stand-by unit that can be connected to
an external 200-volt power source so the refrigerator temperature can be
maintained while the engine off for a long period of time. The stand-by unit
also has a timer function, which can pre-freeze the refrigerator room without
the driver's operation. This helps reduce fuel consumption and manpower
The Hino Profia with an electric refrigerator system reduces the amount of
fuel required to operate its refrigerator. The new truck's fuel efficiency
exceeds Japan's 2015 fuel efficiency standards by 5 percent. Moreover, as
standard features, the Hino Profia has advanced safety systems including an
enhanced pre-crash safety system (PCS)(*) designed to support drivers to
prevent rear-end collision with vehicle in motion ahead, a lane-departure
warning system that issues an alarm at a more appropriate timing, and a driver
monitoring system that provides more precise detection. Thus, the Hino Profia
is a heavy-duty truck that achieves greater environmental and safety
The compact and light-weight hybrid unit, installed to the Hino Dutro Hybrid
with proven results in the market, was optimized as an energy source for this
new refrigerator. This enables improved eco-friendly performance, while
minimizing effects to load capacity and maintaining economy performance for the
heavy-duty truck. 
Hino will continue to offer useful products that are environmentally safe and
user- friendly. And DENSO will continue to develop products and technologies
that help automakers increase the environmental performance of their vehicles
to promote a more eco-friendly society. 
Target annual sales - First year: 180 units
