Residential Geothermal Air Conditioning

How Do They Work?
Remember, a geothermal heat pump doesn’t create heat by burning fuel, like a furnace does. Instead, in winter it collects the Earth’s natural heat through a series of pipes, called a loop, installed below the surface of the ground or submersed in a pond or lake. Fluid circulates through the loop and carries the heat to the house. There, an electrically driven compressor and a heat exchanger concentrate the Earth’s energy and release it inside the home at a higher temperature. Ductwork distributes the heat to different rooms.
In summer, the process is reversed.

The underground loop draws excess heat from the house and allows it to be absorbed by the Earth. The system cools your home in the same way that a refrigerator keeps your food cool – by drawing heat from the interior, not by blowing in cold air.

The geothermal loop that is buried underground is typically made of high-density polyethylene, a tough plastic that is extraordinarily durable but which allows heat to pass through efficiently. When installers connect sections of pipe, they heat fuse the joints, making the connections stronger than the pipe itself. The fluid in the loop is water or an environmentally safe antifreeze solution that circulates through the pipes in a closed system.

Another type of geothermal system uses a loop of copper piping placed underground. When refrigerant is pumped through the loop, heat is transferred directly through the copper to the earth.

As with any heat pump, geothermal and water-source heat pumps are able to heat, cool, and, if so equipped, supply the house with hot water. Some models of geothermal systems are available with two-speed compressors and variable fans for more comfort and energy savings. Relative to air-source heat pumps, they are quieter, last longer, need little maintenance, and do not depend on the temperature of the outside air.

Egg Geothermal Heating and Cooling uses the Earth’s constant temperature to achieve EER’s (Energy Efficiency Ratings) in the 30’s.  The heating COP (Coefficient of Performance) is approaching 5.  A 5 COP indicates that the Egg Geothermal Systems are producing 5 units of energy for every unit of electricity consumed.  The other 4 come from the Earth.  That’s why this technology is called “renewable”.

Not only gas prices are soaring nowadays; electricity bills are, too. In some countries, a lot of people have started utilizing electricity sources that bring about more savings. The most common are the so called solar panels, which are able to make use of solar power to produce electricity. Electricity that comes out of solar panels is more popularly known as residential solar energy that can help you save on electricity bills. How the said type of energy is produced is something that needs to be answered.

Panels that bring about solar power actually work in a simple manner: their job is to ensure that the sun’s light is transformed into usable energy that will give their users the electricity they need. This is done through silicon atoms that bond with each other in order to facilitate electron-sharing and therefore help in giving off electricity.

Part of the process of producing electricity through panels that produce solar power is combining silicon atoms with the photons that are produced by the sunlight. Once silicon atoms, their electrons, and the photons are mixed together, electricity is generated. Take note however that for a big amount of electricity to be produced, a lot of solar energy is also needed, which equates to the fact that more solar cells are also needed.

Some people may think that solar power producing panels may be hard to obtain, let alone placed in their homes. The truth, however, is that there are now various manufacturers that offer solar panel kits that come with easy installation and are definitely easy to use. The said kits also come with tools, better known as inverters that enable the production of power for home use.

If you have the desire to purchase solar panel kits, keep in mind that to get maximum benefits and to ensure that the output works properly, have those kits installed by the experts. Though it may be true that those kits are extremely easy to install, there are still some factors that may affect the performance of your finished product such as the roof angle of your residence, the directions the solar panel’s trackers face, and many more.

Finding out everything about how solar energy may be produced and how solar panels may be utilized are usually some ways of motivating people to consider the use of solar power in their homes, offices, shops, etc. Electricity produced from panels that emit usable energy may also be used in street lights, lighthouses, and even in traffic signs. Through the use of solar power, the process of energy conservation is practiced. Take note too that the electricity a user gets from solar panels may be described as reliable and very simple to maintain.

In our world that is bombarded with the rising prices of utilities, specifically high electricity bills, the only way to save a significant amount of money is to look for other sources of energy. Residential solar energy has a lot of benefits that we can enjoy for as long as we learn the right ways to obtain it.

Product Description
Interest in residential geothermal systems has grown as more people realize they can replace their fossil-fuel heating system with one that is three to five times more efficient and doesn’t require a chimney to exhaust noxious fumes. These newer, safer systems provide heating as well as cooling simply by transferring heat between the home and the ground or a nearby body of water. Since this is a relatively new technology, the number of experienced installers is limited but growing. Therefore,there is a burden on homeowners interested in installing one of these systems to absorb as much information about residential geothermal systems as possible. This book was written specifically to meet that need.

Readers will learn how heat pumps are able to extract heat from relatively low temperature water circulating in ground loops and raise it to a temperature high enough to heat a home. They will also learn how to estimate the size of the heat pump required and the ground loop size as well for straight 2-pipe, 4-pipe, 6-pipe and Slinky loop configurations. This is important in order to verify that the installer correctly sizes the system. Both horizontal and vertical loop systems, for GX and DX, are covered.

Some of the technical issues that are addressed include: Loop water flow rates and Reynolds Number, heat of extraction/rejection, heating capacity, desuperheater setup, open-loop/closed-loop, SCW, pond loops, DX, Manual-J, COP. The final chapter consists of a set of flowcharts guiding the homeowner to ask the pertinent questions needed for a successful installation.

Residential solar systems are crucial if you are planning on reducing the energy costs in your home. In a time when the prices of petroleum and coal are increasing, it is only but wise to start using renewable power sources such as solar energy to help power up our homes. Besides, it is the responsibility of every citizen of the world to help in the preservation of the environment for future generations. It is a known fact that climate change brought about by the drastic increase in greenhouse gas emissions from coal-run power plants is already affecting the world. Although installing solar power systems in your home is effective in bringing down energy costs and helping the environment, there are several ways in which you can further reduce home energy expenses in your home, particularly if you are not living 100% off grid.

But even if you can rely on residential solar systems to power your lights, heaters and other electronics at home, you probably still need to use traditional electricity resources. One way for you to minimize your electricity bills every month is by changing some of your wasteful habits. You should encourage your whole family to follow your lead. Some of the things that you should remember include turning off all appliances, lights and anything that is powered by electricity when not in use. If you are just leaving your computer or television for short periods, you can just leave it on sleep mode.  It is also very important that you keep your cooling and heating units clean at all times so that they will function efficiently.

Even if you are using residential solar systems to provide electricity for your home, it is still wise to carefully choose the electrical equipment or appliance that you are using. Some appliances are not energy efficient and can rack up your energy costs or waste the energy generated from your solar power system. When you are buying refrigerators, televisions, air conditioning units, and other appliances, you should make sure that you look for energy efficient ones. Although they may be a little bit more expensive, at least in the long run, you will be saving a lot more on electrical costs. Aside from appliances, you should also start changing your light bulbs from incandescent light to energy-saving light bulbs. Not only are these more efficient in providing you with adequate lighting, they also consume less electricity.

Sometimes, the reason why you are spending a lot on electricity is due to structural problems in your home. For example, substandard insulation in attics can contribute to higher cooling costs during the summer. If you have solar attic fans, your utility expenses as a result of using cooling appliances will be reduced significantly. Air leakage is also a problem. So, start looking for holes and gaps in windows and doors before the summer and winter months arrive.
