non pressure flat plate solar water heater

タイトルまたは説明

Characteristics
ONOSI flat type collector,basically using well combing multi-assemble way,such as roll extrusion or rolling way and so on,in which the thermo resistance between water tube and heat absorber plate almost can be neglected.The main factors that affect flat type collector board core performance are as follows: one is construction design,second is the surface absorber coating.Well designed collector's board core heat efficiency should above *3%
1.Flat type solar energy collector is metallic conduit type construction;it has high heat efficiency,large quantity hot water yield,pressure bearable,and sunburned resistance.Water is heated in the copper tube,the quality is sustainable and reliable,free of maintenance as well as *5 using life span.
2.No freezing resistance,it is appropriate to be used at warm place where no ice to be formed in the winter.It's reasonable at price and excellent at performance.
3.Specification: 1*2 square meters,hot water yield in sunny days is *****0kg/square meters
4.High absorb efficiency:Þs>*5%,low emisive rate:£h<2%,day average heat efficiency µd>*5%

Material:
1.Inner tank:SUS****2B,0.4mm
2.Outer tank:drawbench silver steel,0.4mm
3.Frame:aluminium alloy,2.0mm
