개요
This study was carried out to file up using effect and requirement of energy for environmental design data of Pleurotus eryngii growing houses. Heating and cooling Degree-Hour (D-H) were calculated and compared for some Pleurotus eryngii growing houses of sandwich-panel (perrnanent) or arch-roofed (simple) type structures modified and suggested through field survey and analysis. Also therrnal resistance(R-value) was calculated for the heat insulating and covering materials of the perrnanent and simple-type, which were made of p이yurethane or p이ystyrene panel and 7~8 layers heat conservation cover wall. The variations of heating and cooling D-H simulated for Jinju area was nearly linearly proportional to the setting inside temperatures. The variations of cooling D-H was much more sensitive than those of heating D-H.
Therefore, it was expected that the variations of required energy in accordance with setting temperature or
actual temperature maintained inside of the cultivation housε could be estimated and also the estimated
results of heating and cooling D-H could be effectively used for the verification of environmental simulation
as well as for the calculation of required energy amounts. When the cultivation floor areas are all equal,
panel type houses to be constructed by various combinations of materials were found to by far more effective than simple type pipe house in the aspect of energy conservation maintenance except some additional cost invested initially. And also the energy effectiveness of multi-span house compared to single span together with the prediction of energy rεquirement depending on the level insulated for the wall and roof area could be estimated. Additionally, structural as well as environmental optimizations are expected to be possible by calculating periodical and/or seasonal energy requirements for those various combinations of insulation level and different climate conditions, etc.
