Next week is the big week

Events next week:

• The UN Climate Change Conference kicks off in Copenhagen (COP 15) and Leaders of the Commonwealth countries called Saturday for a legally binding international agreement on climate change and a global fund with billions of dollars to help poor countries meet its mandates. The 53-nation meeting was the largest gathering of international leaders before next month's global climate summit in Copenhagen.
  
• Barack Obama receives the Nobel Peace Prize in Oslo


• ....and an important step for us: the JAHUS project will finally be completed

Progress:

As mentioned above, they have promised to finish the JAHUS project this week. Tuesday next week we have agreed to meet here and they will formally hand over the project to us - and give us instructions on how to operate the new ventilation system (and the heatpump).

Until then, I'm afraid there will be very little to report from our project. (Nobody showed up today either - so I guess they're planning a busy end to this week).
















The attached picture shows one page from the Users Guide that follows our new ventilation aggregate. In the middle of the picture there is something standing up like a factory chimney with a mysterious thing at the end (marked 5). This is the discharge of extract ("used") air. I have pointed out that the discharge of extract air from our house is creating too much noice - and reminded them of the fact that there should be a silencer at the end (it's not here now).

The picture also shows noice-traps on the pipes coming in to- and when the air is leaving the aggregate (for distribution in the house). These noice traps are also missing, but I hope they will fix this before hand-over next Tuesday.

The most critical point except for the noice level, is the ventilation system's ability to both effectively capture the energy in the exhaust air - and to distribute the heat from the heatpump. In my last blog post I mentioned that I believe they have to alter the solution to make this work (adding the heated air AFTER the heat-exchanger in the aggregate). We'll see one week from now....
