Summary

This study aims to propose a liquid desiccant ventilation system and investigate the energy benefits of this system in comparison with a conventional variable air volume system. The proposed system is operated to achieve ventilation, dehumidification, and water heating. An energy simulation is performed via a series using TRNSYS 18 and the Engineering Equation Solver program. The simulation results demonstrate that the proposed system can save 27% of the primary energy in comparison with the reference system. The use of tap water for solution cooling instead of a cooling device is the main reason behind the significant energy savings. The heat exchanger used to provide hot water for the building with the aid of the scavenger air also reduces the overall operating energy of the proposed system.
