Variable operating conditions characteristics of circulating wheel dehumidification air conditioning system

Abstract For its efficient application of low-grade energy, the circulating wheel dehumidification air conditioning system has received a lot attention and research in response to shared challenges environmental protection, energy conservation, low carbon. Desiccant systems can recycle waste heat as desiccant regeneration source improve quality, which is expected achieve consumption high-efficiency dehumidification. The divided into treatment channel regenerative channel. Treated directly sent room after cooling, discharged outdoors completion regeneration. Therefore, new type recirculated established. In this paper, experimental study carried out. Dehumidification characteristics under variable working conditions are quantified studied. Compared with water cooling unit, rate improved effectively. effects different treated temperatures (28 °C–40 °C) relative humidity (50%–85%) obtained. experiment shows that proposed effectively compared conventional direct condensation seawater. Under same shunt coefficient, increases gradually increase temperature reclaimed air. an optimal value, corresponding circulation coefficient 50%–75%, decreases regenerated
