Optimize and Validate the Performance of a Solar Air Conditioning System Under Jordanian Climate

摘要

In this project, the performance of a solar Air Conditioning (SAC) system was studied and optimized under Jordanian climate. The SAC is based on adsorption chiller operated by hot water produced by a field of flat plate solar collectors of 59 m~2 area located at Mango Center for Scientific Research – University of Jordan in Amman. The analysis was done experimentally using monitoring devices for five days and theoretically using TRNSYS simulation software.rnThe obtained experimentally results show that the SAC system operates with an average thermal and electrical COP during the experimentation days of May and June 2014 of 0.33 and 2.1 respectively. The driving thermal power was between (10–13) kW and chilled power output was between (1.5–4) kW.rnThe results of the experimental work on the pilot plant have been used to assess the performance of the system as well as to calibrate and validate the TRNSYS models.rnOptimization the performance of SAC system was achieved by studying the effect of two parameters; first, the area of the solar collectors, and second, by varying the temperature of the chiller starting set point of the hot water supplied from the hot storage, and the optimal values are 84 m~2 and 83 ℃, where primary energy ratio was the highest after examined a different collector’s area and temperatures. A primary energy ratio and the primary energy ratio for a corresponding reference system have been calculated to be 0.8 and 1.0 respectively. The need to improve the performance of the SAC system is to get a better value of PER than that of the conventional system then we can save primary energy.
