| Summary: | 碩士 === 國立中央大學 === 能源工程研究所 === 98 === The main purpose of this research is to design a compact adsorber with high performance, which will be applied to a solid adsorption cooling system. A test system is build up in order to measure the adsorption and desorption performance of the test section.
Micro-heat exchanger concept is applied to design the adsorber heat exchanger. The smaller tube size is chosen to replace the bigger tube which is widely used in the former research. Meanwhile, a thin-layer coating technique
is used to develop a adsorber—adsorbent is directly coated on the heat exchanger surface.This thin-layer coated adsorber will accelerate the response time including heat transfer and mass transfer. So this micro-heat exchanger design with a thin-layer coated adsorber is expected to reduce the whole system volume and enhance the performance to decrease the cost of adsorption cooling
system.
The test results show that adsorption/desorption temperature has significant effect on performance. When adsorption time is 1 minute, the adsorber has the maximum adsorption rate— 0.567 g/s. When desorption time is 4 minute, the adsorber has maximum desorption rate— 0.109 g/s.
