    Go Sun Solutions - Make Your Own Air Conditioner

    Source: Renewable Energy UK
    20% of all electricity in the USA is used by air conditioning units. The power consumption of air conditioners renders them incompatible with all but the largest domestic renewable energy systems, and so people living off-grid typically have to do without. In this article we will look at how a very cheap and simple room cooler can be put together, powered by a 12 Volt battery or directly from a PV Solar Panel.


    DIY Groundsource Heat Pump Cool Fan

    Once you dig more than a few feet down, the temperature of the ground is pretty much constant throughout the year. This is the key to Geothermal (Groundsource) Heat Pumps - systems which keep buildings cool in the summer and warm in the winter with great efficiency. Using this fact it is possible to put together a simple room cooler using nothing more than thin plastic tubing, a small circulation pump, a fan, and a few fittings.

    A coil of plastic tubing is buried 1+ metres below ground level where it will find consistent temperatures of around 11-12 degrees Celcius year-round. It is connected through a hole drilled in the wall (or through a window / ventilation brick) to the fan via a closed loop. The hose, or ideally copper tubing is wound around in a spiral at the back of the fan, so the air drawn into the fan is pre-cooled to below the ambient summer air temperature.

    The tubing can be attached to the grille of the fan very easily using cable ties.

    Anti-freeze or heavily salted water is ideal to act as the coolant pumped around the system since it will not freeze when the system lies dormant in the winter. Since the air in the room is hotter than the air in the ground, the coolant takes heat from the air before it is blown out from the fan and then deposits it in the ground. This set up is a basic heat exchanger.

    Any small circulation pump can be used to move the coolant around the system. 12V aquarium pumps can be perfect, as can the pumps typically used in solar water heating systems, and in ornamental garden water fountains. All of these pumps have very low power consumption, and can be powered with a 12V battery.


    Super Cooling Homemade Air Conditioner

    If more rapid cooling is required, and energy efficiency is not such an issue, then an alternative to using the ground as a source of cool is to use an insulated container filled with icy salt water. Using a copper coil in the icy water, a copper coil at the front AND rear of the fan, and flexible tubing to complete the loop (via the pump), a hot room can be cooled to a comportable level in 10-20 minutes.

    The earth absorbs almost 50% of all solar energy and remains a nearly constant temperature of 50°F to 70°F depending on geographic location. Working with an underground loop system, a ClimateMaster geothermal unit utilizes this constant temperature to exchange energy between your home and the earth as needed for heating and cooling.

    Click here to watch a video about how geothermal systems work.

    In winter, water circulating inside a sealed loop absorbs heat from the earth and carries it to the unit. Here it is compressed to a higher temperature and sent as warm air to your indoor system for distribution throughout your home.

    In the summer, the system reverses and expels heat from your home to the cooler earth via the loop system. This heat exchange process is not only natural, but is a truly ingenious and highly efficient way to create a comfortable climate in your home.

    Looks like a glorified swamp cooler.

    Nice drawing, nice theory, I dont buy it but I wont try and tear it apart. I imagine if it really worked we would see these things everywhere. Pumping of fluid would be the biggest concern, pumping fluid takes a tremendous amount of energy.

    Anyhow, let me know when you get it hooked up, I would love to see if it works. I will be the last one to buy one.

    One thing though, if we built Nuclear power plants there would be no need for this. Problem is power companies want huge profits which green energy gives them, massive subsidies and tax breaks. Many power companies are owned by corporations that supply the materials to make the fiberglass to make windmills, so the corporations are getting rich selling the materials to build windmills in which they than get a tax break and subsidy to install, they also get permission to raise electrical rates to cover the cost fo the windmill. Of course at best they will get 1% of the power from expensive windmills the rest will come from the same old cheap sources of power, but marked up in price justified by windmills.

    Green energy is nothing but a giant scam

    Real dumbass thing to say. I heat my swimming pool with a solar array. On the north side of the house LOL. And the cost of the pumping of the water is an infintismal fraction of what it would cost me to heat it with electricity.

    In the 50s and early 60s, the statements were made that nuclear would be too cheap to meter, and was completely failsafe.

    Then came the bills and Three Mile Island.

    Nobody is buying that shit anymore. Nuclear is clean, but expensive and not foolproof.

    Old Crock, you keeping track of the amount of times you dont back up anything you say, I will have to make a thread just to keep track of every one of your giant gaffs.

    Check this out for instance, in this thread you are so wrong, lets see you address this, so far you have ran away and hid from everything. As far as your swimming pool is concerned, everything I have challenged you on you have failed to support your position so based on your performance defending your threads I would say you are full of shit in regards to all of your claims.

    So how much energy and what types does it take to produce a ton of fiberglass. Old Crock has no idea about this or anything else when challenged.

    Just take a look at this thread:

    I think you are at a point that you will only believe whatever you want to believe, rather than what great advances technology has made that might actually be sustainable.If I wanted to invest 20 grand, I could do that, and have a nice new car out in the driveway...
    I don't own my home, though, so right now its not an option. I have several years before that happens. =(

    It's a clever idea, but a single fan would only cool off a small apartment, at best. This might be practical in 3rd-world countries, but here in the US, people would rather have central AC hooked up to some solar cells.

    Is that as far as you guys got? The picture of the do it yourself project???

    Besides.. there is a reason why the fan is connected to the ducts under the floorboards..

    Did anyone see the massive copper piping below? That one is not do it yourself, and many people in the UK have this kind of system, and it powers their whole house.

    How do you repair damage to the underground coil? This could prove very problematic to areas prone to earthquakes, or animals that burrow. And any heating system will eventually need maintenance over time...how deep of a hole would you need to dig to access the "professional" geothermal system?

    Not to mention it would be dangerous in cities built near sea level (New Orleans).
