Flat Plate Solar Water Heater
ONOSI flat type collector, basically using well combining 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 93%.
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 15 using life span.
2. No freezing resistance, it is appropriate to be used at Guangdong, Fujian, Yunnan, Guangxi, Hainan and other districts where no ice to be formed in the winter. It's reasonable at price and excellent at performance.
3. Specification: 1×2 square meters, 55? hot water yield in sunny days is 75?140kg/square meters
4. High absorb efficiency: αs≥92?, low emissive rate ?εh≤10?, day average heat efficiencyηd≥55?
Central hot water system of solar energy is a heatcollection and water supply system that is organically composed by heat collector,heat preservation water tank,control system, automatically water feeding control tank,circulating pump, pipeline fittings and so on. It is turned into heat energy by the collector through collecting solarirradiation and turns cold water into hot water.
Automatically full of water is carried out by automaticallywater feeding tank and achieves:thermo circulation--theimprovement of heat collection efficiency;pipelinecirculation-the coming of hot water by opening the waterfaucet.
Size: 150L, 200L, 250L, 300L, 400L, 500L with single coil or double coils inside tank.
