Abstract

A liquid desiccant-assisted dedicated outdoor air system (LDADOAS) with organic Rankine cycle (ORC) was proposed as a centralized ventilation system applicable to high-rise apartment buildings. The LDADOAS consists of a liquid desiccant dehumidifier and an indirect evaporative cooler for conditioning the minimum required outdoor air ventilation. The ORC considered in this research is a combined heat and power system to accommodate common electricity demand of the apartment building. The heat released from the ORC is used for regeneration of the desiccant solution in the proposed system. Energy performance of the proposed system was compared with existing dedicated outdoor air systems via detailed energy simulation. The result showed that the LDADOAS consumed 48% less primary energy consumption compared with conventional dedicated outdoor air system considered in this work because most of regeneration heat required for the proposed system was supplied by the waste heat recovered from the ORC.
