Operation Characteristics of Desiccant Air Conditioning System

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.departmental bulletin pape

Observation of Wind Conditions at Nishimera Village, Miyazaki

The energy consumption of Japan is increasing, because the energy is used in the large field of daily life. This energy consumption is supported by fossil fuel imported from foreign like the oil and coal. On other hand, the hilly and mountainous areas of Miyazaki Prefecture has focused on natural energy like the wind power energy. Nishimera village of Miyazaki has interest to combined power generation system that combined the some kind power generation methods like the wind power, solar power and hydro power. If the combined power generation system can stable supply of energy, the system will be supply the electricity to agricultural building of Nishimera village. In this study, authors are sat the wind observing system, because they measurement wind speed and wind direction in the Nishimera village. The measurement result was used for calculate of generation power energy. In addition, authors visited to farmer of Nishimera village. Then, the consumed electrical energy and environment of agricultural building of Nishimera village was research. As a result, the authors found that the wind come from the east in many cases, and the wind speed gradually increased between summer and fall. Concomitantly, the expected generating power also began to increase. And, authors expected from calculation result that the six wind generators of maximum output 3kW need.departmental bulletin pape
