Abstract :
An alternative method using the ground heat exchanger to provide cooling water for a solar-driven CACS is proposed with the aim to improve the performance. Using a mathematical model developed in this study, theoretical analyses are carried out to investigate the performance of the combined system. The results show that with an additional compressor, the system can be driven by 50°C hot water, and the pressure ratio has obviously effect on the cooling capacity. These make the system can operate with the flat-plate solar collectors and fit for variable cooling demands. The effects of driving temperature on the system performance are also investigated.
