Absorption refrigeration technology has attracted more and more interests due to its advantages such as making good use of low grade thermal energy and using environmental friendly refrigerants. The internal heat recovery capacity of an ammonia water absorption refrigeration system has...

The internal heat recovery has great influence on the performance of an ammonia water absorption refrigeration system. This paper presents an intuitional graphical analysis to identify the characteristics of different cycles with different internal heat recovery strategies and to find out the...

An air-cooled two-stage NH3-H2O absorption refrigeration system is proposed for potential application of residential small scale cooling system driven by solar heated hot water. It can reduce the initial fabrication and maintenance costs of both the solar collection system and the absorption...
