Summary

This paper presents a lithium bromide absorption refrigerator that does not use a mechanical pump for solution circulation. In this refrigerator, the solution circulation is achieved by making use of pressure in the generator. To achieve this, the generator is designed to carry out two functions, namely desorption and circulation, alternately, and is served by two operational valves. A mathematic model for the solution circulation is developed to predict the refrigerator's performance. Results from the model show that this refrigerator can give a similar COP to that of single-effect refrigerators with mechanical pump circulation. Some structural effects affecting the refrigerator's performance, based on the mathematic model, are also discussed.
