Let’s study the
technical specifications of a Saunier-Duval HR 2.02 solar collector.
Referring to the indicated technical specifications of the above Saunier-DuvalHR 2.02 solar collector, complete the diagram below by adding the missing dimensions.
Referring to the indicated technical specifications of the Saunier-DuvalHR 2.02 solar collector, complete the table below and specify the units.
The manufacturer refers to the optical efficiency as “solar efficiency”.
This should not be confused with the global efficiency which can be calculated according to given operating conditions.
The optical efficiency should not be confused with the following coefficients:
- α : coefficient of absorption
- ε : coefficient of emission
These coefficients specify the qualities of the absorber inside the collector.
Thus, the collector in question has:
- An optical efficiency of 85%
- An emission coefficient of 5%
- An absorption coefficient of 95%
To what does it refer and what is the use of the information on lines 5, 9, 10, and 13 of the technical specifications shown for the Saunier-Duval H2.02 solar collector?
