The main component of a geothermal HVAC system is the heat pump, which is a type of thermal exchange system. These systems use a loop that exchanges the thermal energy to provide your HVAC system with thermal energy for both heating and cooling. Geothermal systems are great for year-round energy savings, but you will want to choose the type of loop that is right for your home. Here are some of the different choices for a geothermal heat pump to make your HVAC system more efficient:
1. Closed Loop Systems for A Complete Commercial Geothermal System
The common commercial solution for geothermal energy is a closed loop system. This is a system that has a circuit of pipes that are sealed and filled with an antifreeze solution. The solutions exchange thermal energy below the ground and is circulated back through the refrigerant in an AC or other thermal exchange processes with heating and other mechanical systems. This is an ideal solution for larger systems that may use geothermal designs for refrigeration, heating or other mechanical uses, such as in boilers.
2. Cost-Effective Solutions in Ponds or Lakes to Provide Effective Energy Efficiency
Large bodies of water provide a cost-effective solution for geothermal systems. With a pond or lake, the geothermal loop is sunk to the bottom of the body of water, where the lines are protected from extreme temperatures and the water is a consistent temperature. There are requirements for the depth and size of body of water for these types of systems to work properly.
3. Wells and Open-Loop Systems Where They Are a Practical Geothermal Solution
An open loop system is where fresh water is circulated through the system to provide the thermal exchange. These systems are ideal for well systems where space is limited for the installation of conventional vertical loop systems. There are some restrictions that may prohibited the use of a conventional open-loop system, such as regulations prohibiting the use of an open-loop system or poor water quality. If you are in an area with frequent droughts and dry weather, then an open-loop may not be an ideal system.
These are some of the choices of heat pump loops that help make HVAC systems more energy efficient. If you are ready to install an energy efficient heating and cooling system for your home, contact an air conditioning contractor and talk with them about one of these systems for your home.
