A car air-conditioning system based on an absorption refrigeration cycle using energy from exhaust gas of an internal combustion engine

Energy from the exhaust gas of an internal combus-tion engine is used to power an absorption refriger-ation system to air-condition an ordinary passenger car. The theoretical design is verified by a unit that is tested under both laboratory and road-test condi-tions. For the latter, the unit is installed in a Nissan 1400 truck and the results indicate a successful pro-totype and encouraging prospects for future devel-opment.
