How To Make A Simple Solar Powered Geothermal Air Conditioning Unit
A geothermal heat pump or ground source heat pump (GSHP) is a central heating and/or cooling system that transfers heat to or from the ground. It uses the earth as aheat source (in the winter) or a heat sink (in the summer).
Although many parts of the country experience seasonal temperature extremes — from scorching heat in the summer to sub-zero cold in the winter—a few feet below the earth’s surface the ground remains at a relatively constant temperature. Depending on latitude, ground temperatures range from 45°F (7°C) to 75°F (21°C). Like a cave, this ground temperature is warmer than the air above it during the winter and cooler than the air in the summer. The GHP takes advantage of this by exchanging heat with the earth through a ground heat exchanger.
You can make your own (simplified) geothermal air conditioning unit from an old radiator from a car. This can be used to cool your home, cabin or shed, even a root cellar. The great thing about this project is that it is ran off solar. So this would be a great off the grid cooling system to have.
Before you see how to make one for yourself, check out how a geothermal system works, this will give you a better idea of what this is all about and hopefully blow you mind a little…
