AB  - In order to recover the waste heat from the exhaust gas of a combustion engine an adsorption
refrigeration cycle is proposed. This is a preliminary study on design and testing of a prototype of absorption
refrigeration cycle powered by an internal combustion engine. The heat source of the cycle is a compression
ignition engine which generates 122.36 W of heat in generator of the cycle. The pairs of absorbent and
refrigerant are water and ammonia. Here the generator is made of a shell and tube heat exchanger with number
of tube and its length are 20 and 0.69 m, respectively. In the experiments the exhaust gas with a mass flow rate
of 0.00016 kg/sec, enters the generator at 110°C and leaves it at 72°C. Here, the solution is heated from 30-90°C.
In the evaporator, the lowest temperature can be reached is 17.9°C and COP of the system is 0.45. The main
conclusion can be drawn here is that the proposed system can be used to recycle the waste heat and produced
cooling. However, the COP is still low.
