Abstract

Abstract: The demands and schemes for the moisture load disposal in cooling ceiling air-conditioning sys-tems by using fresh air were investigatedreaching the conclusion that adsorption dehumidification is better than cooling dehumidification．Experimental results of the moisture load removing by rotary de-humidifier and the feasibility of implementation schemes show thatin summerthe rotary dehumidifier can satisfy the system demands when the outdoor air temperature and humidity are respectively lower than30℃ and80％ besides office buildingsand thatin the high-temperature and high-humidity areasthe rotary dehumidifier can satisfy the demand for indoor humidity and the demand for low humidity by the head surface cooler preprocessing of the fresh air．Moreoverthe indoor relative humidity can be controlled by regulating the regeneration temperature and the fresh air flowrate of rotary dehumidifier．

Key words: rotary dehumidifier, cooling ceiling air-conditioning system, moisture load
