Sorry about my posting from 1 March.   I listed the Yahoo site twice.
You can get the entire TEXT on this Google site:

http://groups.google.com/group/Energy-Conservation-in-Housing

However, the Yahooo site includes diagrams as well as the text, but it
requires a more complicated sign-in process to access the files.

Re-do of earlier message:

I made a homemade HRV in 1988, and used it in my house from 1988
through 2005 (when I moved).  The HRV got about 71% heat recovery, by
my measurements.

(The inside house / exhaust temperate was 68 F; the outside
temperature was +8 F.  The incoming air is pre-heated to 51 F.
Inside to outside: 68-8 = 60 T; intake air pre-he=
at: 51 - 8
= 43 T; 43  60 = 71.6% recovery)

The description of this HRV can be found on my Google site:
http://groups.google.com/group/Energy-Conservation-in-Housing

Or To get the complete documents (with diagrams) you can get it on a
Yahoo site, but you have to go through a sign-in process to access
the Files and photo information:
http://groups.yahoo.com/group/EnergyConservationHousing

I hope this is useful to you.

As well as data on HRVs, the below link has a 150-page book, Energy
Conservation in Housing, which was published in 1990 and 1992.  This
electronic version has some recent updates.  The Google site has the
text only.  The Yahoo site has the entire book text and diagrams as a
PDF document, and can be downloaded / copied.  It is about 1.5MB in
size.  (The Google site has links to the Yahoo site.  See the
"files" and "photos" on the Yahoo site.)
    The book, Energy Conservation in Housing, demonstrates in layman's
terms the principles of energy-efficient housing.  As well as
descriptions of insulation methods, it also includes data on Heat
Recovery Ventilators, including homemade versions of HRVs.
