Performance Studies of R134a-Dimethylformamide Absorption Refrigeration System for Utilizing Bus Exhaust Gas Based on Aspen Plus Software

This work presents an experimental study of an ammonia-water absorption refrigeration system using the exhaust of an internal combustion engine as energy source. The exhaust gas energy availability, the performance of the absorption refrigeration system and the engine performance are evaluated. A commercial turbocharged Diesel engine has been tested in a bench test dynamometer, with the absorption refrigeration system adapted to the exhaust system. The maximum COP obtained from the refrigeration system is 0.136 and it has been shown that heat energy available with exhaust gas is capable of producing sufficient cooling capacity for air conditioning the vehicle without requiring any energy input from the engine.

Wasted Heat

Aiming to execrable heat condition of the armored vehicles and serious waste of the engine wasted heat, it researched refrigeration system scenario using wasted heat. According to the armored vehicles’ overall demands and advantages and disadvantages of each kind of refrigeration technique using wasted heat, it selected absorption refrigeration technique using LiBr as the basic cooling manner, and it designed the method to introduce the wasted heat in the exhaust gas. On the base of theoretic estimating of wasted heat energy and endurable temperature of the person and devices in the vehicle, it designed several primary technique indexes. According inner overall setup and the engine features, it designed and analyzed one prototype of the absorption refrigeration system.
