Sediment method: Single target magnertron sputtering plating C. Specific absorption: 0.90~0.93(AM1.5) D. Emission ratio: 0.05~0.075(80ºC± 5ºC ) 4. Idle sunning property parameters: Y=220~260m². ºC/KW 5. Solar irradiation for obtaining a preset water temperature H=4.14.4MJ/m²(¦µ58) H=3.13.4MJ/m²( ¦µ47 ) 6. Average heat loss coefficient: 0.6~0.7W/(m². ºC) 7. Usage life: 15 years Adding one more complete glass tube in the normal tube, raising the heating efficiency by decreasing the water content, not the heating area. The heating efficiency can improve 30%by this way. |
