Abstract
Control of the temperature and relative humidity in greenhouses is very important in the agricultural sector. This study proposed a combined heat pump and desiccant air conditioning system to control temperature and relative humidity in greenhouses. The performance of dehumidification in the desiccant and the influence of regeneration temperature were verified by experiment. It was found that the dehumidification performance improved when the regeneration temperature was high. It was found that desorption and adsorption ratio 2:1, achieved the largest dehumidification rate.
