1. To investigate the feasibility of cooling at summer by cold river water, a case study was made concerning Nagasaka open channel, which flows down irrigating the southern district of Kanazawa. (1) The water temperature and flow were measured twice during 3 days at 5 points scattered in the distance of 3 km. It was disclosed that the water temperature at the upper stream was kept at 20<plus-minus>1ﾟC, whereas the atmospheric temperature fluctuated around 28ﾟC.A mathematical model based on heat transfer theory was constructed to explain the measured temperature of water. (2) As a case study, a specificplace was chosen to concretely estimate costs for cooling. A fan-coil unit cooler (FCU) was assumed in present study. The pumped-up water in radiator coil was cool-ed with an electrical fan. It was found that cooling by FCU costs 15 yen less per an hour than by an ordinary electrical coole2. The heat equivalent to 8ﾟC water at Uchikawa dam lake in winter was extracted with a heat pipe and used for snow melting for 3 months. The occurrence of snow melting was verified through mathematical analysis.3. Temperatures of sewage and treated water were measured in winter of 1996 at a sewage control center. The difference between the water and atmospheric temperatures in winter was 10ﾟC, which value is sufficient for snow melting.4. To evaluate the cooling effect of sprinkling grounds with water, a baseball ground was sprinkled with the treated sewage water in summer of 1995. It was found that the drop in atmospheric temperature was about 4ﾟC.

1。为了调查夏季冷河水在夏季进行冷却的可行性，对长崎开放河口进行了一个案例研究，该通道流向灌溉金泽南区。 （1）在3天内，在散布在3 km的距离的5点下，在3天内测量了水温和流量。据披露，上流流的水温保持在20 <plus-minus> 1 c c，而大气温度在28°C左右波动。基于传热理论的数学模型被构建为解释水的测得的温度。 （2）作为一个案例研究，选择了一个特定的地方来估算冷却成本。在本研究中假设了风扇线圈单元冷却器（FCU）。散热器线圈中的抽水用电风扇冷却。发现FCU冷却的价格比普通电动Coole2少15日元。在冬季，冬季湖湖湖的8 c水等效的热量是用热管提取的，用于雪熔化3个月。通过数学分析验证了雪熔化的发生。3。污水和处理水的温度在1996年冬季在污水控制中心测量。冬季的水和大气温度之间的差异为10°C，这足以进行雪融化。4。为了评估用水洒水地面的冷却效果，1995年夏天，撒上处理的污水水洒了一个棒球场。发现大气温度的下降约为4°C。
