This idea is for places where the weather is hot for part of the day and cold for part of the day, such as some deserts.

This idea is partly already in use in some contexts.


Have a storage of bricks or water to hold heat. Two units, one for hot and one for cold, stored outside with insulation.

A fan blows air over the bricks from outside, heating them up or cooling them down depending on the outside air temperature.

At night when it is cold, a fan blows over the warm bricks and into the house to warm it up.

During the day, a fan can blow over the cold bricks that were cooled during the night to push cold air into the house to cool it.


Advantages

Quite cheap to purchase and install as there are few components. Very low ongoing electricity costs.

If the brick storage is large, there is almost unlimited amount of heating and cooling available.

Very quiet operation.

Very simple to manufacture.

Suitable for combining with solar heat panels or solar electric panels.


Disadvantages

Not suitable for environments that are hot during the entire 24 hour cycle, or cold during the entire 24 hours.

Would probably need some electical heater/cooling as backup depending on weather conditions.
 
Would take up more space outside than a conventional heater/cooler.
