Progress - in Copenhagen and in our JAHUS

Event 1: Video clip
As world leaders arrived in Copenhagen yesterday, a nice videoclip was released to further highlight the need for serious committments from both developed- and developing countries. Watch the video clip here:

Event 2: Back to work
United Nations talks on fighting climate change finally turned to the details of how to combat global warming on Thursday after 36 hours of wrangling over procedural issues. Officials expressed relief that the procedural row had ended at last, but warned that the dispute had wasted precious time just a day away from the end of the conference.

"I would say: hold tight and mind the doors, the cable-car is moving again," the UN's chief climate negotiator, Yvo de Boer, told journalists in Copenhagen.

Progress:
Today they finally installed the connection between the pipe with heated air from the heatpump (the pipe in the lower right side of the picture) and the pipe that blows fresh air from the aggregate to the distribution network in the house (the pipe in the upper left corner of the picture). The new setup is exactly what I asked for in an earlier blog post (and in discussions with the subcontractor). The design is also illustrated in my technical sketch which is attached below.

As shown in the picture above, the new setup includes a fan (the lump on the connection between the two pipes) - and because the electrician hasn't connected the fan to the electrical grid in the house, the functionality can not yet be verified. I hope that we can test it for the first time tomorrow and publish some results during the weekend.

Tomorrow the carpenter has promised to move/adjust the "doghouse" that was built around the heatpump (outside). We believe the current construction is causing more noice than normal from the heatpump - because the "doghouse" is attached to the outside wall and probably transmits vibrations to the house.

It is -10C in Kolbotn now and the exhaust air is therefore below zero (C). As I expected, there is condensated water building on the un-isolated pipe as shown in the next picture. I have forwarded this picture to the ventilation experts and told them that I believe that this particular pipe should be isolated. The last picture was included to illustrate how cold one of the valves is under such conditions.
