DEVELOPMENT OF ENERGY SAVING SYSTEMS FOR GREENHOUSES IN COLD AND LOW INSOLATION REGIONS -PERFORMANCE AND EVALUATIONOF THE FOUR ENERGY SAVING SYSTEMS BY MEANS OF DYNAMIC SIMULATION-

概要 （図表や脚注は「報告書全文」に掲載しております）

地中熱交換温室・ペレット温室・トレンチ温室の北陸地方への適用性について，非定常シミュレーションモデルを作成し検討を行った。また，この結果を基に，地中熱交換温室にペレット温室の保温機能を付加したシステムを考え，モデルによる検討を行った。地中熱，ペレット，トレンチの各温室とも北陸の気象条件下では十分な性能が得られない。しかし，地中熱交換温室にペレット温室の機能を付加したシステムは北陸の気象条件下でも適用が可能であると認められた。

概要 （英文）

UNDERGROUND HEAT EXCHANGE GREENHOUSE,PLLET GREENHOUSE AND SEMI-UNDERGROUND GREENHOUSE HAVE BEEN DEVELOPED ORIGINALLY FOR THE CLIMATE OF THE PACIFIC OCEAN COAST AND WERE RELATIVELY POPULAR ENERGY SAVING SYSTEMS. TO DEVELOP THE ENERGY SAVING TECHNOLOGY FOR GREENHOUSES FITTED FOR THE CLIMATE OF THE HOKURIKU REGION,MATHEMATICAL MODELS OF THESE ENERGY SAVING SYSTEMS WERE DERIVED AND ADAPTATION OF THESE SYSTEMS TO THE HOKURIKU WAS STUDIED BY MEANS OF DYNAMIC SIMULATION.FURTHERMORE,THE NEW ENERGY SAVING SYSTEM BASED ON THE RESULTS OF THE SIMULATIONS WAS DESIGNED AND ITS PERFORMANCE WAS EXAMINED BY THE MATHEMATICAL MODEL. ACCORDING TO THE DATA FOR THE LAST FIVE YEARS,CHARACTERISTICSOF THE CLIMATE OF THE HOKURIKU,AS COMPARED WITH THAT OF THE KANTO REGION,WERE LOW INSOLATION,HIGH HUMIDITY AND COLD.IT WAS SUPPOSED THAT THESE METEOROLOGICAL CONDITIONS WERE SEVERE ON DEVELOPING THE ENERGY SAVINGTECHNOLOGY FOR GREENHOUSES. THE TEMPERATURE REGIMES OF THE THREE SYSTEMS ORIGINALLY FOR THE CLIMATE OF THE PACIFIC OCEAN COAST WERE SIMULATEDBY MEASURED DATA OF THE AMBIENT AIR TEMPERATURES AND INSOLATIONS AT TOYAMA.THE AIR TEMPERATURES INSIDE THE GREENHOUSES OF THESE SYSTEMS WERE AT LOW LEVEL AND LITTLE DIFFERENT EACH OTHER.IT WAS RECOGNIZED THAT THESE SYSTEMS FACILITATED ENOUGH TO SAVE THE ENERGY FOR THE GREENHOUSES. THE NEW SYSTEM,WHICH WAS ADDED THE HIGH INSULATION ABILITY TO THE UNDER GROUND HEAT EXCHANGE SYSTEM, WAS SIMULATED UNDER THE WEATHER CONDITIONSOF ONE FINE DAY AND NEXT TWO SNOWY DAYS.THIS SYSTEM WAS ABLE TO MAINTAIN THE MINIMUM AIR TEMPERATURE INSIDE THE GREENHOUSE 5.5 CENTI DEGREE HIGHER THAN THE AMBIENT AIR TEMPERATURE.THEREFORE,IT WAS ASSUMED THAT THIS NEW SYSTEM WAS MORE SUITABLE THAN THE OTHER THREE SYSTEMS FOR THE CLIMATE OF THE HOKURIKU.
