| 講演要旨(和文) | | 比較的低温の温泉廃湯を冬季ハウス栽培の熱源として利用するための実験を試みた．システムの特徴として，廃湯を熱源とする．その熱源と熱交換して昇温した水道水をヒートポンプの蒸発器に流入させ冷媒と熱交換する．ヒートポンプの圧縮機で高温された冷媒は凝縮器で，水と熱交換して適切な温水にする．その水を放熱管に流入し，土壌加温，室内加温に用いる．放熱管を地表下60cmに設置して，主として土壌加温の効果と伝熱挙動について実験した．実験用に4種類の作物を用いた．なお本研究は男鹿市「緑の分権改革」推進事業の一環として行われた． |

| | 講演要旨(英文) | | An experiment on greenhouse cultivation in winter season was conducted using remaining heat after bath use as heat source. The heat source is thermally exchanged with the circulatory normal water, which is increased by temperature, then flowed to the evaporator in order to transmit heat to the refrigerant. Next, the refrigerant heated by the compressor is thermally exchanged in the condenser with the circulatory water, which is heated up to the proper temperature. The warmed water flows in the radiator tube to heat in the soil and the green-house. In this experiment, the radiator tube is horizontally installed 60 centimeters below soil surface and examined the effect of soil heating and the behavior of heat transmission, with planting four kinds of crops. This research is co-operatively done for an Oga-city project of Ministry of Internals and Communications. |
