Air-to-air heat/energy exchangers are often used with heating or cooling systems in buildings, to transfer heat and moisture from an airstream at a high temperature or humidity to an airstream at a low temperature or humidity. Frosting inside heat/energy exchangers is common in cold regions such...

In this study, a membrane liquid desiccant air conditioning (M-LDAC) system is modeled using the TRNSYS building energy simulation software. Liquid-to-air membrane energy exchangers (LAMEEs) are used as a dehumidifier and regenerator in the proposed M-LDAC system to eliminate the carryover of...

A review of the literature on liquid desiccant-to-air permeable-membrane energy exchangers will indicate opportunities for future research and application of this new technology in HVAC systems. HVAC systems are responsible for a large fraction of energy consumption and some airborne emissions...

Buildings are responsible for a significant portion of the global energy consumption. In particular, heating, ventilation, and air-conditioning (HVAC) systems in buildings consume significant amounts of energy. Liquid desiccant dehumidification and energy recovery are effective energy...

A liquid-to-air membrane energy exchanger (LAMEE) is an energy exchange device that transfers heat and moisture between air and salt solution streams through a semi-permeable membrane which is permeable for water vapor but impermeable for liquid water. LAMEEs have been used as a...

Energy recovery from exhaust air to condition or partly condition outdoor ventilation air has been proved to be an effective method for building energy conservation and is now required in many building Codes and ASHRAE Standards for most commercial buildings. Nonetheless, existing energy...
