OK I understand that efficiency includes an element related to the energy required/gained to change the Relative Humidity but in terms of comparison that isn't important - just as well as I am never going to have the time to get to grips with that!!! So, should I run a mile from the HR200V?]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10859&Focus=179334#Comment_179334 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10859&Focus=179334#Comment_179334 Sun, 07 Jul 2013 12:47:04 +0100 Gotanewlife
"The unit should retain up to 70% of the temperature differential of out going air" this appears to be Vent Axia way of avoiding the question!! This on the VA Integra - and on Max is extracts 49l/s but used 182 watts giving a SFP of 3.7! Crikey!]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10859&Focus=179376#Comment_179376 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10859&Focus=179376#Comment_179376 Mon, 08 Jul 2013 09:30:22 +0100 jms452
'Thermal Efficiency' is like assuming the air is dry and is fair enough for most purposes. You can tell it is not a real efficiency as you will find graphs of thermal efficiency going up to 100% when the air inside is at high RH and its cold outside.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10859&Focus=179433#Comment_179433 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10859&Focus=179433#Comment_179433 Mon, 08 Jul 2013 15:47:56 +0100 SteamyTea http://www.engineeringtoolbox.com/overall-heat-transfer-coefficient-d_434.html]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10859&Focus=179462#Comment_179462 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10859&Focus=179462#Comment_179462 Mon, 08 Jul 2013 18:36:46 +0100 piersadler http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10859&Focus=179469#Comment_179469 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10859&Focus=179469#Comment_179469 Mon, 08 Jul 2013 19:04:51 +0100 Gotanewlife Posted By: piersadlermakes the Vent Axia system look better than it is
Well I couldn't work out why but for sure something smelled fishy, so I ran my mile and bought something else

Now I have found:
Thermal energy recuperating efficiency up to 68%

Which I think is not a fudge just poor translation from Ukraine but also the same unit is described as:

Moisture recuperating efficiency: Up to 65%

It didn't bother me and I bought it!]]>
