Today we finished off re-installing an air duct to drive fresh air into our temporary living quarters. We needed more air pressure to serve the four extra living spaces attached on the side of the garage. We ran a 150mm aluminium laminated foil tube along the ceiling just under the light channel down the Garden Room, and then down to the existing air duct that runs off into the temporary living quarters.
The chimney is to transfer the “air” from the cupboard at floor level, pass the cooking section and up to the ceiling, and trying to minimise destructions of our work surfaces.
We have learnt a valuable lesson regarding air ducting and how sensitive the performance of the delivery of “air” is in the real world!
