A heating and cooling system for a vehicle having an internal combustion engine is provided. The system comprises at least one exhaust pipe (16,18) conveying exhaust gases away from the engine, and a reactor vessel (38,40) located in the exhaust pipe (16,18) and containing an absorbent salt and a refrigerant fluid. A condenser (50) is in fluid communication with the reactor vessel (38,40), and receives refrigerant vapour from the reactor (38,40) when exhaust gases heat the reactor vessel in the exhaust pipe (16,18). An evaporator (54) is locatable in a cab (56) of the vehicle and is in fluid communication with the condenser (50) and the reactor vessel (38,40). The evaporator (54) receives condensed refrigerant from the condenser (50) so as to cool the air surrounding the evaporator (54), and returning refrigerant vapour to the reactor vessel (38,40). A method of cooling a driver environment of a vehicle having an internal combustion engine is also provided, as is a vehicle incorporating the heating and cooling system. |
