In this study, the performance of a diffusion
absorption refrigeration (DAR) system using solar energy is investigated
experimentally. For this purpose, two types of systems with/without sub-cooling
are used for the experiment. Two-phase closed thermosyphon type heat pipes
using water as the working fluid are used to utilize solar energy as heat
source. During the experiments; ambient temperature along with critical point
temperatures on DAR systems and heat pipes, DAR systems pressures and solar
radiation data are recorded from 06:00 to 16:00 and each heat pipe has
collected 82.5W of solar energy. DAR1 has achieved its lowest evaporator inlet
temperature (-14.8°C) at 14:40, and DAR2 has reached -0.9°C at 13:55. COP
values of DAR1 and DAR2 are found as 0.2362 and 0.2254. Efficiency of the heat
pipes used in DAR1 and DAR2 are 0.3677 and 0.3690, and their thermal resistance
values are 0.1154W/°C, 0.0828W/°C respectively
