The purpose of the present work was to develop a greenhouse growing system with a night cooling facility using geothermal energy to grow fall and winter vegetables during high summer temperatures. In this paper, the authors first designed and constructed a greenhouse cooling facility using geothermal water for the driving energy, and then conducted a cooling performance test and growth experiment in the growing of vegetables. As a result of the investigation, first, the facility showed the cooling performance as designed, since the air in the greenhouse was cooled to the desired temperature of 15 C. Second, in the open division, almost all the spinach, lettuce, and Kinusaya peas died back during growing and there was therefore no yield. However, in the cooling division, all the vegetables grew normally and their yields were large. From the results mentioned above, the authors concluded that it is possible to grow vegetables during the high-temperature summer season in greenhouse cooled only at night.
