摘要

Resorption refrigeration is a prospective technique for recovering the waste heat from engines with its high performance and nonexistence of liquid refrigerant, which is a safety concern. Five high-temperature and three low-temperature halides are analyzed for general recognition on the performance of a resorption cycle. Considering the instability of the heat source from the exhaust gas and the continuous requirement of cooling, the energy storage function is analyzed for the cycle. Results showed that the working pair of MnCl2-CaCl2 is an optimal choice, and the experimental cycle adsorption quantity is as high as 0.49 kgNH(3).kg(-1)MnCl(2) when the heating, cooling, and refrigerating temperatures are 150 degrees C, 30 degrees C, and 5 degrees C, respectively. The phase change materials 58.1LiNO(3)-41.9KCl and 82Ga-12Sn-6Zn are chosen for the storage of waste heat and refrigeration capacity, separately. Analysis shows that 4.19-and 4.73-kg composite adsorbents of CaCl2 and MnCl2 will be required for a 3-kW refrigeration system, and the air conditioner could provide cooing for more than 2 h with the energy storage function by phase change materials when the vehicle has stopped.
