常见液体除湿剂池内核态沸腾换热特性
Pool nucleate boiling heat transfer of conventional desiccant solutions
摘要
Abstract
Boiling regeneration of liquid desiccant solution can reduce the dependence of desiccant air-conditioning on the outdoor environment. The study on boiling characteristics of solution is significant for the design of boiling regenerators. In this study, the pool nucleate boiling characteristics of three conventional desiccant solutions and one formula desiccant agent were investigated experimentally. For the three desiccant solutions, the boiling temperature increases with the increase of concentration; their heat transfer coefficients are lower than that of water and decrease with as concentration increases, but when the concentration increases to a limit so that small particles precipitate, the heat transfer coefficient increases. For similar mass transfer capacity, the boiling heat transfer performance of lithium bromide solution and calcium chloride solution is superior to that of lithium chloride solution. With the addition of a certain amount of calcium chloride solution, the boiling heat transfer performance of lithium chloride solution can be optimized.关键词
