Annual evaluation of energy, environmental and economic performances of a membrane liquid desiccant air conditioning system with/without ERV
Abdel-Salam, Ahmed H.; Simonson, Carey J. - In: Applied Energy 116 (2014) C, pp. 134-148
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...
