Catching moments of collecting cool air after sunset

After we had finished installing roof collection panels, air path pipes, air handing unit, system sensors and other related hardware and plumbing parts, we test run the system on daily basis. In the beginning we had problems to run the system in summer night cool air intake mode. After adjusting the system settings and the exterior temperature sensor location, we have successfully run the set C system in the mode.

Beside the blue color on the bottom left corner of the display panel, the true indicator showing the system is working in summer night cool air intake mode is this: the temperature inside the collection panels are LOWER than both the exterior and interior temperatures as a result of the collection panels’ capability of releasing heat further as the cool air is being collected. See two photos of set C’s display on two August 16 and 22: Continue reading “Catching moments of collecting cool air after sunset”

After finishing installing heat collector panels for both set A and set C (see two pictures for each finished set), one of our installation team could attend the Solar Canada 2018 expo in Calgary – this expo typically hold in Toronto and this year 2018 is the fist time in Calgary and next year 2019 also in Calgary.

Today is the drywall day. Because the second floor will be turned into three legal suites, a lot of fire rated drywalls need to be installed. In fact, this whole week can be called the drywall week!

More framing for the garage floor – well, now the floor for a kitchen. Originally it was planned to level off this former garage floor with concrete. It turned out that a lot of concrete is needed just for this purpose. So now we have changed to frame the whole floor with 2×8 wood, then plywood on top of it, and lastly hardwood floor.
