Geothermal HVAC
Geothermal HVAC has been around for a long time. Unfortunately there has been little promotion of the concept in the past. Builders of new houses and HVAC professionals tended to stay away from this type of heating and cooling. Why? That is a good question. Possibly it is the cost of installation. It is not a secret that a Geothermal HVAC system will cost more to install. It is not because using Geothermal HVAC to heat and cool your home is not good. To the contrary. With a Geothermal HVAC system you will use less energy. There are no gas emissions to destroy the atmosphere. There is no worry about carbon monoxide poisoning There are more benefits to these systems. Over time, the system will pay for itself. Year after year you will enjoy savings due to this system. Especially as the price of gas (Natural and Propane) goes up.
A better understanding of Geothermal HVAC
In a nutshell, Geothermal HVAC takes the heat out of the earth in the winter, heat mode, and puts the heat in the earth in summer during cooling mode. We are not going to get into a lesson on Geothermal HVAC here, but there are some basics that you should know. The ground loop for Geothermal HVAC can be in many forms. Your loop can be an open loop, closed loop, pond or lake loop, coiled loop, etc.
The ground loop of a Geothermal HVAC system acts as the fins on an air conditioner compressor. As the solution is circulated through the loop during the winter heat is transfered from the earth to the solution. During the summer, heat is transfered to the earth from the solution. Depending on the system, in the winter heat from the ground loop is then transferred in the Heat Pump from the ground loop solution to a freon loop. This freon is then sent to the Air Handler which then transfers the heat or cold to the air. During the summer, the process is the opposite. The heat from the freon in the Air Handler is transferred to the ground loop solution.
Why thegeoconnection
This site was developed to assist people in the research and installation of Geothermal HVAC systems. The main purpose of this site is to promote the installation of Geothermal HVAC systems in smaller residences, less than 10,000 square feet. The bulk of the information on proposed and installed systems on the internet seem to be in larger building, government facilities, schools and other institutions. The homes which we can find information on seem to be larger in the range of greater than 10,000 square feet. Geothermal HVAC systems are great for smaller installations also.
