How to build an Inexpensive Geothermal Solar Air Conditioning System to Cool your Garage using an Old Car Radiator ,Solar Panel.

Pin

This project goes over the build of a cheap Geothermal Solar air conditioner that can cool your home with the Earths natural cool temperature.

A few feet underground, the temperature remains between 55 and 60 degrees Fahrenheit. This is true regardless of the weather above ground.The geothermal unit siphons heat from inside and vents it into the water or refrigerant in the loop. The cool temperature underground then lowers the temperature of the liquid back to 55 degrees.

In my case when I draw the water well, the static water level is 2 feet above the ground and and what that means that there is a free flowing well that runs down the hill.

This is connected to a 55 gallon drum buried in the ground to keep it cool. A circulator pump is used to pump the water to the radiator.

The water well is about 85 feet.We drop a 10 foot pipe in there and get a cheap pump from a car and probably some check valves valves and maybe start a natural siphon and run out of solar.

You will need an old car radiator for this project. The Radiator used here is from an old Volvo Car. This is used to circulate air using a solar panel.

The water coming in is connected to the radiator and the water coming out the is attached to a PVC drain pipe . The radiator is hooked to a motor connected to a solar panel.

A Temperature sensor is attached to the radiator fan to detect the indoor temperature. The pump is out of the same Volvo car from which I got the radiator. A Coolant temperature sensor can be added to measure the temperature difference from the inlet versus the outlet and just see how much heat get pulled into the water .

The system works on Solar.You will need a Charge controller,DC to DC Convertor and 12 or 24V batteries.
