T-Car Camp Aircon System 2018

April 2019


Design a cooling system for 6 Shiftpod tents, optimizing for:



This shows half of the system - one aircon and three shiftpods. The second half looks identical (the large ducts are connected to the second A/C box).

Note that the smaller ducts are not connected to the large ducts yet.

This shows the arrangement of shiftpods under our aluminet shade structure, ducting and the position of the A/C units (the box represents both A/C units).

Boxes for the a/c units

Hand-made using lumber, hardboard and thermal insulation.


I removed the face panel from A/C units, and disconnected control panels to allow them to be used from outside of the wooden box.

Self-sticking insulation tape was applied along the edge of the A/C unit (where it will be touching the box):

Boxes are simply screwed to the A/C units. Top:


Take-off vents connected to the box. To protect A/C units from the dust I’ve also installed some aircon filters inside of the box where vents are connected (not visible on the photo).

Big ducts are first connected to the take-off vents and attached using duct tape and zip ties (well, not yet attached on the photo below).

Then another layer of duct tape and zip tie over the insulation layer:

Smaller ducts don’t have separate insulation layer (they are pretty short and mostly indoors) and have a T-shaped connector (“Tee Saddle”) at the end that needs to be attached to the big duct:

I could not find a good way to attach t-shaped connectors to the big ducts, so ended up cutting holes in them, inserting connectors, and duct taping over it. Something like this (note this T-connector does not yet have a smaller duct attached to it):

Materials and cost

Was this worth it?

Overall, it was a fun project, but it if you can afford dual-vent aircon units for each shiftpod (and a much bigger generator), it will be much simpler and more effective.
