Co-generation system has become an effective method to solve the global warming and energy problem.The system can achieve high efficiency both by using electric generation and by exhaust heat recovery. On the other hand, the development of the environmental improvement technology in a greenhouse is demanded agricultural sector. It is thought that a desiccant air conditioning system can solve these problems. In this paper, experiments aimed at establishing system operation methods according to absolute humidity of outside air were conducted. Firstly, the experiment was conducted with air volume of both blowers on dehumidification side and regeneration side set to 640 m3/h. As the result, it was confirmed that temperature and relative humidity inside the greenhouse could be controlled to target ranges of inside the greenhouse when absolute humidity of outside air is less than 17 g/kg. Secondly, the experiment was conducted when absolute humidity of outside air was very high.In this case, air volume of both blowers on dehumidification side and regeneration side were set to two different conditions. First condition of the blowers is 640 m3/h and another one is 740 m3/h. At the result, it was confirmed that setting the air volume of the blowers to 740 m3/h is better when absolute humidity of outside air is high.
