低温驱动沸石-水吸附式制冷机的性能研究

Experimental Investigation on a Zeolite-water Adsorption Chiller Driven by Low Heat Source

本文研究的合成沸石-水吸附式制冷机采用FAMZ01沸石作为吸附剂,吸附床选择翅片涂抹式吸附床,通过实验研究该制冷机的制冷功率、制冷性能系数(COP)随热源温度、冷冻水进口温度的变化规律。结果表明,该吸附式制冷机在55℃的热源下就可以稳定输出制冷量,并在驱动热源为65℃左右展现其较佳的性能。

A novel type of adsorption chiller with synthetic zeolite-water was proposed, in which the zeolite FAMZ01 was chosen as the ad- sorbent and coated adsorber with fin as adsorber. The effects of heat source temperature and chilled water inlet temperature on cooling power and coefficient of performance （COP） were obtained experimentally. The results showed that the adsorption chiller can supply the chilled water steadily at driven heat source temperature of 55℃, and is with better performance at the driving heat source temperature about 65℃.
