1 Solar collector with Germany ultrasonic welding 2 black chrome coating 3 Low iron tempered glass 4High density polyurethane 1.The Introduction of Flat Panel Solar Collector pressurized type
a.A flat panel solar collector consists of an absorber, a transparent cover, a frame, and insulation.
b. The transparent cover of flat panel solar collector prevents wind and breezes from carrying the collected heat away (convection).
c.The insulation on the back of the absorber and on the side walls lessens the heat loss through conduction. Insulation is usually of polyurethane foam or mineral wool.
d.Easy and convenient to realize standalone, roof-integrated, roof-mounted solutions and facade-integrated
2.Features compare to vacuum tube collector
(1) More energy output from a unit area, less roof occupied;(2) Plate-grid structure, fluid heated in the copper pipe with faster heat transfer; (3) Working with pressure, better stagnation performance;(4) Graceful outline, well matched to the building;
3. Advantages of DAILY flat plate solar thermal panel
(1)Blue titanium coating, with high absorptivity 95±2% and low emissivity 4±2%, stable performance, life span 50years;(2)Special design structure, 360°heat transfer, excellent thermal conductivity;(3)Optical low iron tempered glass cover, light transmit up to 92%, reflection and refraction make the “greenhouse effect” shaped in the cavity, reduce heat loss
