ABSTRACT

Energy from the exhaust gas of an internal combustion engine is used to power an absorption refrigeration 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 conditions. For the latter, the unit is installed in a Nissan 1400 truck and the results indicate a successful prototype and encouraging prospects for future development.

Keywords: car air-conditioning, absorption refrigeration, renewable energy
