Heating and Cooling

One of the things we have been developing while we have been trying to stay under the radar, is a super eco heating cooling solution.

The idea came from the Romans who were pretty smart cookies and didnt like to rely on split air conditioners. By channelling air under / in to the earth's crust, we have stable temperatures which we can utilise for our houses.

All of this is based around negative pressure and thermal dynamics. Check out an experiment we did (which when you see it, looks super obvious and simple). But this is pretty cool. An opening in a PVC plumbing pipe at the bottom, a heat lamp heating the air, then that hot air rising which draws in fresh cold air below while driving the air out the top. Its a ventilation / cooling / heating system using no mechanical parts at all or power (assuming the heat comes from natural sources).

As a result of this knowledge we created a working system for our houses and facilities.

Atomic 6 are working on all kinds of sustainable and cool features, but everything starts with a super thermal house which requires very little heating or cooling. The rest is then more about small variations of heat.

Another reason why Atomic 6 houses are revolutionary, is that we bond everything with 100% adhesion joints. This means that the houses are pretty much completely air tight with the window and door openings being the only way to allow air to enter or exit. If you seal up the windows and doors, eventually you will die :)

So the system we have developed works for a few reasons:

  • to create negative pressure, we have an extraction vent at the top of a room and the bottom of the room. If the room is too warm, the top extraction vent will draw out the hotter air (heat rises). As the heat is extracted, it creates negative pressure and draws cooler air from under the door (the cool air is at the bottom)

  • the negative pressure then sucks air from the floor vent which channels the air under the earth crust via a device we call 'Geothermal Transfer Box'. The pipes allow for greater surface area to help cool or heat the air as it passes.

  • this creates fresh air inside the house also

The vent to the left enters the house. The vent to the left (missing the filter in the pic) sits under the subfloor of the house.

The subfloor of the house is already reasonably stable temperature, as the freezing temps or the heat of summer is sheltered.

The pic above is a little hard to see, but towards the back is the Geothermal transfer box installed under the ground. This area is quite stable in terms of heat and cold.

Typical in mid to lower Australia, the earths crust at around 2m deep is 16degC to 18degC. For the sake of this exercise, we will call it 17degC. So when the air is 42degC, under the soil its 17degC. When it is 0degC, it is 17degC. So all through the year we get a stable temp.

It works better for cooling than heat. We are working on some new ways to heat quick (lots of surface area) while keeping power amps low. We are around 1 week away from a solution I hope. Worse case, we have low watt carbon panel heaters at around 300watts which will heat the houses fantastically. But we are trying for even more efficiency.

NEXT - we have developed already mark 2 of this Geothermal Transfer Box, now a cylinder / probe. This design is only 275mm in diameter, which means we can drop 2.4m deep into the soil the same way / same time as we excavate for footings. This will be more efficient, slightly cheaper and looks cool.

There are 24 pipes down, 24 pipes up. Each providing as much surface area as possible to cool or heat the air as it passes. This will be placed into the soil, then backfilled with fines to fully surround the pipes and create a thermal connection.

At the top is a carbon fibre heating filament which also has heaps of surface area. The testing we have done on this is really impressive, we will try to share some pics of this also.

At the inlet to the house is a dual filter of HEPA filter and activated carbon. This is to clean and filter air / mould etc into the house.

We can update with pics soon when the first prototype arrives. Stay tuned.
