There are two types:
High-grade geothermal energy is the heat of the earth’s pressure that turns water into stream. Old Faithful at Yellowstone National Park is an excellent example. Low-grade geothermal energy is the heat within the earth’s crust. This heat is actually stored solar energy. ECONAR taps into this low grade geothermal energy and delivers big energy savings when heating, cooling and making hot water.
A heat pump is a mechanical device used for heating and cooling which operates on
the principle that heat can be moved from a warmer temperature to a cooler temperature. A geothermal heat pump uses the earth to warm us in the winter and cool us in the summer. You already have a heat pump in your home – your refrigerator. If you put your hand behind it you’ll feel the heat that has been removed from the food inside the refrigerator. This is the same principle that ECONAR uses to move heat to and from the home and earth.
Remember that the heat pump moves heat from a low temperature source to a high temperature source. The process of elevating low temperature heat to over 100°F and transferring it indoors involves a cycle of evaporation, compression, condensation and expansion. A refrigerant is used as the heat transfer medium which circulates within the heat pump. The cycle starts as the cold liquid refrigerant passes through a heat exchanger (evaporator) and absorbs heat from the low temperature source (liquid from the ground loop). The refrigerant evaporates into a gas as heat is absorbed. The gaseous refrigerant then passes through a compressor where the refrigerant is pressurized, raising its temperature to over 160º F. The hot gas then circulates through a refrigerant-to-air heat exchanger where heat is removed and pumped into the home at about 100º F. When it loses heat, the refrigerant changes back to a liquid. The liquid is cooled as it passes through an expansion valve and begins the process again. To air condition, the flow is reversed.
Most solar energy customers don't realize, until they have the system installed, that one of the main benefits of a solar power installation is the independence gained by creating one's own energy. They also become much more aware of the energy they use because their solar panel installation includes a monitor to track their use.
Solar panels are remarkably tough. Most solar panel installations from the 1970's (solar's last heyday) are still in use and producing 80-85% of their original output. NASA has been using solar panels on satellites for more than 50 years. The only maintenance required of your solar panel installation is an occasional cleaning, and is part of your solar installer routine maintenance duties.
Commercial solar panel installation is a very exact discipline. The process begins with a conversation between the commercial building owner and the solar installer about the objectives of the installation. Objectives for commercial installs can vary from helping to offset the everyday energy requirements of a business, to a for-profit commercial solar farm covering many acres of land. The design of a commercial solar installation is the most important element dictating the overall efficiency and output of a given project. If the installation is destined for a commercial rooftop in a metropolitan area, it is essential that the solar installer take precise measurements of roof area, obstructions, and potential shading. While most business owners are driven to embrace solar energy because they want to utilize clean energy sources, they are often surprised to find out that commercial solar power installations can be extremely good business too.
