Geothermal HVAC

Geothermal is a dual-purpose system that provides heating and cooling. The temperature of the earth below the surface remains relatively constant throughout the year.

A geothermal system is made up of a heatpump, underground loops, and a distribution system. Learn more about this energy-efficient system’s components:.

Ground Loop

The Ground Loop is the most important element to a geothermal system’s effectiveness and durability. It is comprised of pipes that can be drilled or slit in the yard to connect with your home’s heat pumps. The pipes are then filled with a water-based solution that circulates to absorb or disperse heat according to the requirements of your home. The ground’s temperature is relatively constant between four and six feet below the surface, which makes it a natural source of energy for geothermal systems.

When the system is heating, the liquid used to transfer heat absorbs heat from the earth. It then carries that heat to the heating pump in your home. The fluid is then pushed back into the loop where it begins circulating again. In cooling mode, it uses the reverse process to remove the heat that is not needed. It returns it back to the loop in order to begin a new cycle.

In a closed loop system, the piping is filled with a solution made of water and buried underground. The solution is safe and non-toxic for the environment. It doesn’t pollute underground water sources. The system can utilize lakes, ponds or other body of water to provide heat transfer fluid. This is even more eco-friendly.

Depending on the space available, closed and open systems may be installed either vertically or horizontally. Vertical systems require fewer trenches and cause less disturbance to your landscaping than horizontal systems. It is ideal for areas in which soil depths are low or when existing landscaping needs to be maintained.

Regardless of the type of ground loop system you choose, it is crucial to select an experienced installer. It is important to have an efficient and well-designed system, as geothermal systems use a lot of energy. A well-designed installation will ensure the durability of your system and allow you to save energy costs in the long run. It is crucial to flush the system regularly to remove any minerals which could affect the flow and effectiveness of the heat transfer liquid.

Vertical Loop

Geothermal energy comes from the Earth and is utilized to cool or heat buildings. This energy can be harnessed by underground loops which absorb thermal energy and transfer it into your home. The most popular kind of geothermal system is called a vertical ground loop. This type of geothermal system is typically used in commercial and residential applications. The system utilizes the heat pump to transfer thermal energy from the earth to your home or office. In the summer, it operates in reverse to provide cooling.

The pipes that are buried store the thermal energy that is transferred from the earth to your house. These pipes are a key element in any geo thermal hvac system. The pipes are made from high-density polyethylene and circulate the mixture of water and propylene glycol which is a food-grade antifreeze, throughout the system. The temperature of the water or soil stays relatively constant for just a few feet below the surface. This allows the closed loop geothermal heat pump to be more efficient than other heating systems, like gas furnaces and boilers.

These loops can either be placed in an excavation horizontally or into boreholes that are drilled from 100 to 400 feet deep. Horizontal trenches are usually used for larger properties with lots of land available and vertical boreholes are best suited for homes or businesses that have limited space. Installation of a horizontal ground-loop involves digging trenches that can take a lot of time and effort. The ground must be compacted to ensure that the loops remain attached to the soil.

On the other hand the vertical loop system can be constructed much more quickly and easily than a horizontal loop field. The technician digs holes of 4 inches in diameter, separated by 20 feet. He then connects the pipe to form a closed circuit. The number of holes needed will depend on the building’s size and energy requirements.

It is essential to keep the loop fields in good condition in order to keep your geothermal system functioning at its best. This includes removing debris and conducting regular tests for bacteriological health.

Horizontal Loop

Geothermal heat pumps transfer energy between your home, the ground or a nearby body water instead of the air outside. This is due to the fact that ground and water temperatures remain relatively stable, in contrast to the fluctuating temperature of outdoor air. There are four primary types of geothermal heating loops and which one you choose to use depends on the size of your property as well as its layout. The type of loop you choose and the method of installation employed determine the efficiency and effectiveness of your geothermal heating system.

Horizontal geothermal heat pumps utilize a series of pipes that are buried horizontally in trenches that range from four to six feet deep. The trenches can hold up to three pipe circuits. The pipe circuits are connected to the manifold, which is the central control unit of geothermal heat pumps. The manifold pumps heated or chilled water into your home’s heating or cooling ductwork.

Originally these piping systems were installed in vertical trenches that required more land area to cover the pipes. As technology advanced it was discovered that laying a single, longer pipe back and forth at various depths in trenches that were smaller could decrease the amount of space needed and also costs without sacrificing performance. This led to the invention of the “slinky method” of installing horizontal geothermal circuits.

In situations where there isn’t enough space, a vertical ground loop system is an ideal alternative. It’s also a great option for homes located in urban areas in areas where the topsoil layer is thin, and there is not enough space for horizontal loops. If your property is located in an earthquake-prone zone and cannot support the horizontal loop, an alternative that is vertical could be the best choice.

A pond or lake geothermal heat pump is the ideal choice for your home when you have access to an abundance of water. This kind of system is similar to a horizontal or a vertical ground loop geothermal heating pump however instead of using the earth for heating and cooling, the water is used. It is important to keep in mind that a geothermal system that uses a pond or lake loop is not functional in the event of an electrical power failure. A backup generator must be installed to supply an electrical source during this time.

Desuperheater

Geothermal cooling and heating is a highly efficient alternative to conventional methods. But when switching to geothermal homeowners must consider balancing upfront costs against total savings on energy. There are many factors to consider including the soil’s composition and the local climate. One of the most important choices is whether or not to bury ground loops, or use an external tank to store hot water. The latter option is more affordable, but it might not offer the same efficiency.

A desuperheater is an equipment used to transfer heat from a geothermal source into your hot water tank at home. It is designed to work in the winter when the cooling process of the system generates excess heat. The desuperheater eliminates this waste heat and uses it to increase the efficiency of your heating system. It also reduces the energy use by using existing resources.

The optimum design for desuperheaters is determined by several physical, geometric, and thermal factors. These variables include the angle of injection, the temperature of the spray water, and the nozzle’s design. These are all aspects that can influence the performance and operation of the desuperheater.

During the summer months, desuperheaters can help save up to 80 percent more in a heating dominated climate than the conventional hot water heater. This is due to the fact that the desuperheater utilizes the energy that is emitted from the home during the cooling process and converts it to useful heat for the hot water generator. The geothermal system can provide hot water to homes for 3 to 5 months a year, at a fraction of the cost of alternative energy sources.

The desuperheater can also help in the winter when the geothermal system is operating at its lowest capacity. The device takes away the extra heat produced by the cooling system and transfers it to the domestic hot water tank. This allows the hot water tank to utilize this free energy and maximizes the heating capacity of the system. The desuperheater can even be used to cut down on the amount of time geothermal systems are in operation in a heating dominated climate.
