Abstract

Abstract:

Traditionally, heat and mass transfer on adsorptive heat exchanger (AHE) is believed to be coupled, the concept of which makes it is hard to design and control the AHE optimally. Here, a novel concept of weak coupled heat and mass transfer is proposed to explain the dynamic behaviors of heat exchanging and moisture removal on AHE, which is based on a lumped parameter method and confirmed by experiments. In this way, heat exchanging and moisture removal can be view as two distinct processes that show great helpful to flexible design of the heat pump with AHE.

Key words: heat and mass transfer, temperature and humidity independent control, unitary adsorptive heat pump

摘要：

传统上，湿空气流经除湿换热器的热质传递过程被认为是耦合过程，这使得研究该过程的热质传递规律及除湿换热器的优化设计变得十分困难。为此，在对实验结果分析的基础上，通过少量的近似处理，提出了一种的对该热质传递过程进行解耦分析的处理方法，从理论上揭示了该类型的单元式固体吸附除湿空调具备天然的温湿度独立处理能力，为后续的空调系统性能分析及除湿换热器的优化设计提供了一个简单有效的分析方法。
