Proposed a remolded SPAR system using evacuated tube as both solar collector and solution generator. Investigated the temperature, mass and concentration variation of the solution in evacuated tube. Calculated the vaporization rate and equivalent refrigerating capacity per evacuated tube. Summarized the thermal collecting efficiency and solar coefficient of performance of evacuated tube. Calculated the total energy absorbed by the solution in evacuated tube and compared the storage density with water tank.
