Abstract: Nowadays, absorption refrigeration cycles using renewable energy or waste heat are very attractive. A hybrid thermoelectric generator/two-stage double-lift ammonia-water absorption refrigeration cycle powered by an evacuated tube solar collector was examined. A detailed thermal analysis was carried out by means of the engineering equation solver. The typical location to install a thermoelectric generator was found to be after the evaporator and desorber 2. The coefficient of performance improves from 0.2 to 0.5 when the temperature difference after desorber 2 is raised from 5°C to 19°C. Installing TEGs after desorber 1 and condenser improves cycle performance by 0.153 and 0.168, respectively.

Keywords: thermoelectric generator; TEG; absorption refrigeration system; ARS; exergy; coefficient of performance; COP; power.
