Total
estimation |
Large amount of wastes for 3 times cutting in process.
Short life for
Sandwitch frame structure.
Slow temperature rise/fall.
Low(No) reliability
Coefficient of Performance did
not increase more than 20 years. |
Only 1 time cutting in process,
very few wastes.
Long life for
center frame structure
Fast temperature rise/fall.
High reliability
Coefficient of Performance increased 25 %. |
| Future vision |
No reliability makes the market smaller. Too much wastes are not state
of the art. |
Very few wastes is tender to the earth, and high reliability gets customers
repeated order. |
