摘要：

The prototype of a novel silica gel-water adsorption chiller is built and its performance is tested in detail. The experimental results show that the refrigerating capacity (RC) and COP of the chiller are 7.15 and 0.38 kW, respectively, when the hot water temperature is 84.8 degrees C, the cooling water temperature is 30.6 degrees C, and the chilled water outlet temperature is 11.7 degrees C. The RC will reach 6 kW under the condition of 65 degrees C hot water temperature, 30.5 degrees C cooling water temperature and 17.6 degrees C chilled water temperature. The results confirm that this kind of adsorption chiller is an effective refrigerating machine though its performance is not as fine as the prediction results. Also it is well effectively driven by a low-grade heat source. Therefore, its applications to the low-grade heat source are much attractive. (c) 2005 Elsevier Ltd and IIR. All rights reserved.
