TL;DR: In this paper, the thermal performance of a Z-shaped enthalpy heat exchanger utilizing 45gsm Kraft paper as the heat and moisture transfer surface for heating, ventilation, and air conditioning (HVAC) energy recovery is investigated through temperature and moisture content measurements.
Abstract: The thermal performance of a Z-shaped enthalpy heat exchanger utilizing 45-gsm Kraft paper as the heat and moisture transfer surface for heating, ventilation, and air conditioning (HVAC) energy recovery is experimentally investigated through temperature and moisture content measurements. A mathematical model is developed and validated against the experimental results using the effectiveness-NTU method. In this model the paper moisture transfer resistance is determined by paper moisture permeability measurements. Results showed that the paper moisture transfer resistance is not constant and varies with moisture gradient across the paper. Furthermore, the model is used to predict the heat exchanger performance for different heat exchanger flow configurations. The results showed that higher effectiveness values are achieved when the heat exchanger flow path width is reduced. Temperature and moisture distribution in the heat exchanger is also studied using a computational fluid dynamics package (FLUENT). To m...

Abstract: This article reviews literature on using membranes in heating, ventilation, and air conditioning (HVAC) applications. Membranes enable the separation of one species from another, and membranes allowing the selective permeation of water vapor can be used to condition air in buildings, potentially more efficiently than conventional HVAC equipment. After a brief background on membrane technology, this review focuses on the following processes: vacuum membrane dehumidification; membrane energy recovery ventilation; liquid desiccant dehumidification; liquid desiccant regeneration; evaporative cooling; and humidification. It highlights the design, modeling, and experimental research on these topics, and suggests areas for further research.
