Co-generation system is one of the effective methods to solve the global warming and energy problem. Effective utilization of heat energy plays an essential roll to introduce electricity-heat cogeneration systems. The authors have proposed to use the low-temperature heat energy in the desiccant air-conditioning system. In particular, in summer season, the excess heat energy can be used for the purpose of dehumidification in green houses by using the desiccant air-conditioning system. On the other hand, the development of the environmental improvement technology in greenhouses are demanded in agricultural sectors. It is expected that desiccant air conditioning system can solve these problems. In this paper, two operation methods of desiccant conditioning system were carried out to set for optimum temperature and optimum relative humidity of various vegetables in the greenhouse. First experiment is "ventilation sysytem", second one is "hybrid sysytem". Experimemtal conditions were large temperature difference and absolute humidity difference between inside and outside the greenhouse. As the result, using the ventilation system, temperature and relative humidity in the greenhouse can not be controlled to optimum conditions. Using the hybrid system, relative humidity in the greenhouse can be controlled to optimum condition. It is confirmed that performance of hybrid system is better than that of ventilation system. However, in hybrid system, further decreasing of absolute humidity is required. In the furture, in this experimental conditions, decreasing of temperature and absolute humidity in the greenhouse are required.
