고성능 제습-증발냉각 공조시스템의 운전모드 제안

Abstract

A desiccant-enhanced (DEVap) air conditioner is recently introduced as an alternative vapor compression HVAC system. The main components of the DEVap are a liquid desiccant dehumidifier and a regenerative indirect evaporative cooler (IEC). The liquid desiccant and IEC reduce the latent and sensible load of the building respectively. The purpose of this research is to propose and evaluate the operation sequence of the DEVap. Based on the load of the building and the condition of the outdoor air, there are four different mode of operation. The simulation is conducted by using TRNSYS 17 program and commercial equation solver (EES) for an arbitrary office building in seoul, Korea.
