The economic analysis on solid-adsorption desiccant technology used in the central air-conditioning system of civil buildings

According to the high energy consumption of traditional dehumidification mode,the technology of solid-adsorption desiccant is proposed to be used in the central air-conditioning system of civil buildings,and the economic analysis of an example using dry fan coil units plus fresh air system with solid-adsorption desiccant and traditional fan-coil unit plus fresh air system separately is given.The results showed,compared with traditional fan-coil unit plus fresh air system,the dry fan coil units plus fresh air system with solid-adsorption desiccant can save 14W/m2 in the summer per day and it decrease the building energy consumption.
