Testing data of pressure solar water heater
The vacuum tube of our solar water heater has high absortion rate and low emission rate
1. Abosortion rate: 0.90-0.93(AM1.5)
2. Emission rate: 0.05-0.075
3. Vacuum tightness: P≤ 5.0*0.0001PA
4. Stagnation tightness: 200
5. Average heat loss coefficient: Ult0.8W(. )
6. Heat preservation: 72 hours
7. Hail resistance: 20-30mm
8. Idle sunning property paramerers: Y=220-260. /KW
9. Avetage heat loss coefficient: Ult=0.6-0.7W(. )
It means the temperature in the water tank is arange from 50 to 95 degree.
It resists 25mm hail and the using life can last 15 years, temperature when exposed to sun without water
