Air conditioning system for lorry cab, includes engine-driven cooling system with condenser and electrically-driven cooling system with thermal storage unit and second condenser

摘要

A first cab cooling system is driven by the vehicle engine and includes a condenser. A second cab cooling system is electrically-driven. This include a thermal storage unit and a second condenser. The second cab cooling system selectively stores thermal energy (cold) whilst the motor is operational. It is selectable to cool the cab, when the engine is idle. It is also selectable to cool the cab when the engine is in operation. The first and second condensers are situated in an airflow duct.
