N°7 – Study of solar collector technical documentation training (A to HND level)

Solar thermal energy and collectors for housing N°7 – Study of solar collector technical documentation training (A to HND level)

Let’s study the technical specifications of a Saunier-Duval HR 2.02 solar collector.
 

Technical data:

Question  

Referring to the indicated technical specifications of the above Saunier-DuvalHR 2.02 solar collector, complete the diagram below by adding the missing dimensions.

Question  

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.

Note:
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%

Question  

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?
