Performance evaluation of a low-temperature waste heat driven multi-bed adsorption chiller

Experimental Investigation of a Three-Bed Adsorption Refrigeration Chiller Employing an Advanced Mass Recovery Cycle

“…Khan et al [13] proposed and numerically evaluated a three-bed mass recovery cycle. They reported that the cycle performance is better than that of the three-bed single stage proposed by Saha et al [14]. Uyun et al [15] proposed and investigated numerically the advanced three-bed adsorption cycle employing heat and mass recovery cycle.…”

Experimental research on dynamic operating characteristics of a novel silica gel-water adsorption chiller

“…This efficiency will obviously be higher when the chiller designed in this experiment is applied to the air conditioning system with low dehumidification load or the industrial cooling water system with a large cyclic flowrate. The influence of the temperatures of the heat source and the chilled water on the dynamic operating characteristics of the chiller is identical to the other chillers [1][2][3][4]9]: the high temperatures of the heat source and the chilled water will cause higher cooling power; the lower chilled water temperature will causes lower COP; but there exists an optimal COP at a certain heat source temperature. For the chiller designed in this experiment, the optimal COP will be obtained when the heat source temperature is in the range of 75-85°C.…”

“…Zeolite-water adsorption systems, such as locomotive cab air conditioners [1,2], have already been studied. Studies on adsorption refrigeration started earlier in Japan, and great success has been achieved in the commercialization of the silica gel-water adsorption chiller [3]. The commercial adsorption chiller is composed of two absorbers, an evaporator and a condenser.…”

Heat-exchanger design and switching-frequency effects on the performance of a continuous type solar adsorption chiller

“…Saha et al [12,13] have proposed a novel multi-bed non-regenerative cycle scheme without mass recovery. The employed working pair is silica gel/water.…”
