| Summary: | With the rapid development of society, the shortage of energy and pollution of the
environment have become more serious. The automobile industry is primarily an
energy consuming one, where each modern automobile is equipped with an air
conditioning system for comfort. The air conditioning systems in automobiles
consumes more engine power, which results in the increase of oil consumption. For
energy saving, many researchers put their attention on the recovery and utilization of
automobile waste heat. Therefore, the project named as "Performance Analysis of an
Ejector Based Vapour Compression Refrigeration System" is proposed for energy
saving and exhaust emission.
This kind of refrigeration system consists of two branches, a traditional vapour
compression cycle and an ejector driven cycle, which introduces an ejector to
compress the refrigerant vapour. In this dissertation, we designed a hybrid structure
for ejector based vapour compression refrigeration system and carried out various
experiments to predict the system performance on the test platform. Finally, the
experimental results show that the ejector based refrigeration cycle has better system
performance compared to traditional refrigeration cycle under different operating
pressure and temperature. This can be further applied to automobile industry for
waste heat recovery and energy efficiency. |
