Album: Cooling


Cooling consists of:
  • Two Carrier A/C units
  • A Fan-Tastic Vent. Model 7000 (110V, motorized lid, rain sensor, wall thermostat)

Because the guy who sold me the bus is an incompetent con artist, the original holes for the A/C units were in the wrong location and the roof hatches were blocked.

I finally moved the front A/C unit so it wouldn't block the vent, and put a Fan-Tastic Vent in it's place. The Fan-Tastic Vent does a really great job of cooling the bus when it's become a greenhouse (i.e., when the inside of the bus gets hotter than the outside because of solar energy). The vent opens and closes automatically, which is great, but it works best if it has a window open in the bus. I might figure out some way to automate a screened window to open.

Eventually, as far as automation goes, I'll need to have a multi-stage thermostat of some sort, or else computer control (someday), because I might want to control these steps.

The A/C unit removed
and the fan ready to drop in. ( comments)
I cut two corners
on the new A/C location, and sawzall the lines. ( comments)
The new fan
and A/C dropped in to check spacing. ( comments)
I frame the inside of the roof
to help support the A/C weight using some simple 1.5" wood ( comments)
