Denso has developed the world’s first refrigeration cycle system for passenger vehicles that uses an ejector. The system is used for both an air conditioner and cooler box (vehicle refrigerator). By using an ejector that rapidly injects and expands high-pressure refrigerant, the energy that previously was lost in the expansion valve is converted to pressure energy and reused, thus boosting energy efficiency. As a result, high cooling and refrigeration performances are both achieved even when the cooler box is used.
The new system is installed on Toyota Motor Corporation’s Land Cruiser, launched in Japan in September. This system will also be installed in the Land Cruiser launched in October in North, Central and South America, Asia, and other regions throughout the world.
