Study on the effect of the difference of absorption cycles on the characteristics of double-effect absorption refrigerator

As a result of the problem of ecological destruction due to the use of CFC, HCFC, HFC, the use of absorption refrigerators has been attracting greater attention, and improvement in the quality of these refrigerators is in demand. There are three types of solution flow for the double-effect absorption refrigerator. They are series flow, parallel flow, and the reverse flow; each has its own characteristics. As yet little research into the differences in performance according to solution flow type has been conducted. Therefore, definitive comparison of the performances has not been made yet. This study aims to clarify the differences in the double-effect absorption refrigerator which result from the solution flow type. The differences in characteristics of double-effect absorption refrigerators driven by gas depending on the three types of solution flow were developed and compared using a simulation model. As a result we were able to identify the merit of each flow type.
