Abstract
Taiwan, geographically located at West
Pacific subtropical monsoon-climate area is
in hot weather condition and the
bio-production in structure greenhouse needs
tremendous mechanical equipments for
adjusting their living temperature. Therefore,
designing a productive building which in
compliance with the criteria of security,
economic, and indoor climate environmental
control, may uplift farmer’s efficiency of
conducting a relative creatures business.
This research adopts〝STAAD-III〞structural
analysis software to simulate double layers
structure. In the premise of structural security,
we implement the economic design to reach
the cost orientation purpose. To constructing
an single greenhouse, the most economic
structure is the design of physical stress
contribution : outer skeleton 3/4’’ , inner
skeleton 1’’, the steel consuming quantity per
unit measure is 5.14kg/ m³, the unit volume
cost is NT＄240/ m³. In the aspect of heat
flux,〝Fluent〞computational fluid dynamics
model software to probe into double-layers
shed cover greenhouse inner heat circulation
and heat radiation status. By using such
method to imitate monocline greenhouse
model , the exploration of heat loss rate and
maintaining the in-house temperature. In
summer, Double-layers shed cover
greenhouse, when an air vent was shut, the
hot air flows out through both side outlets is
the best way to drain out hot air. Thus, the
most energy-saving optimization module in
the summer is using outer wall PE film
100-150cm high , inner wall 100-150cm high,
and outlet-off module. In winter, when an air
vent was fully opened ,it offers better in
house air quality and ventilation. Thus, the
best module of energy-saving optimization in
the winter is utilizing outer-wall PE film off ,
inner-wall film 150-200cm high and
Outlet-On.
