硅胶-水吸附式制冷机组变热源下制冷性能（Refrigeration Performance of a Silica Gel-Water Adsorption Chiller Driven by Variable Heat Source）
吸附式制冷 低温储粮 变热源
2009/9/25
根据吸附式制冷在使用过程中存在的变热源问题，对燃气内燃机余热驱动的吸附式制冷机组进行了实验研究。机组采用硅胶-水作为吸附工质对，由2个解吸/吸附真空腔和1个蒸发器热管工作腔组成。实验结果表明，变热源温度65℃时吸附式制冷机组的制冷功率能够达到变热源温度90℃时的63%，制冷系数变化较小。机组瞬时制冷性能具有很好的可重复性和稳定性。证实了吸附式制冷机组变热源运行时可靠性高，低温性能良好。将吸附式制冷...
