碩士 / 國立勤益科技大學 / 冷凍空調系 / 105 / In face of the problem of global warming, energy conservation and emission reduction has become an important topic at present. In recent years, great attention has been paid to indoor environmental quality affected by climate changes in Taiwan. This research applied solid dehumidification to replace the traditional dehumidification to improve the environmental humidity. In addition to the reduction of energy consumption, the regeneration performance of solid dehumidification materials can also be used to achieve the goal of environmental protection.
According to the research findings, the series combination of bump type heat exchanger has the better absorption/desorption effect than the traditional flat-plate heat exchanger, and its instantaneous maximum absorption rate has improved by about 10.2%~38.6% compared with series combination of flat-plate heat exchanger. On the other hand, the use of waste heat for desorption can significantly improve the efficiency. At the desorption temperature of 60℃, the efficiency of 3 different series combinations of heat exchangers has been respectively increased by 117.5% and 115.1% when the waste heat (90℃ and 120℃ waste heat) is used. In particular, when the waste heat is used at the low air speed of desorption side, its desorption capacity is higher than that of higher air speed. Moreover, simulation software was applied to conduct Velocity Flow Field Analysis and it is found that by-pass type heat exchanger has the more uniform velocity flow field distribution than that of high air speed
