Absorption refrigerator is getting attention with a view point of environmental protection and energy savings because it can be driven by waste heat. As absorption refrigerator has a lot of solution which is so expensive, this makes it difficult to reduce the initial cost and improve the response speed in start up and shut down. Hence, it is expected to reduce the charging quantity of solution. But if it is decreased too much, disturbance such as the charge of the waste heat affects the characteristics of the absorption refrigerator greatly. To investigate these problems, it is necessary to clarify the dynamic characteristics of the absorption refrigerator. In the elements of the absorption refrigerator, the generator has the largest amount of solution and is affected directly by the change of the waste heat Therefore this research aims to clarify the dynamic characteristics of the generator in detail by simulation and experiment. As the generator for the absorption refrigerator, a pool boiling type and falling film type generator have been used. In this paper as the first report, the dynamic characteristics of the pool boiling type are investigated with simulation and experiment. As a result, detailed dynamic characteristics were clarified, and the validity of the dynamic model of the generator was confirmed.
