Geothermal HVAC

Geothermal is a two-in-one system that can provide heating and cooling. The temperatures of the earth below the surface stay fairly constant throughout the year.

A geothermal system is comprised of an underground heat pump, loops and a distribution system (such as air ducts). Learn more about the various components that make up this energy-efficient system.

Ground Loop

The Ground Loop is the main element to a geothermal system’s efficiency and longevity. It consists of pipes that are trenched or drilled in the backyard and connected to the heat pump in your home. The piping is then filled with a water-based fluid that circulates to absorb or disperse heat according to the needs 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 a geothermal system.

When the system is in heating mode the heat transfer fluid absorbs Earth’s heat and then carries it to the heat pump inside your home. The fluid is then moved into the loop where it starts circulating again. In cooling mode, it employs the opposite method to eliminate the heat that is not needed. It returns it to the loop to begin a new cycle.

In a closed loop system the piping is filled with a water-based solution and placed in the ground. The solution is safe for the environment. It is not a pollutant to underground water sources. The system can utilize a pond, lake or other body of water as a source for heat transfer fluid. This is even more eco-friendly.

Both closed and open systems can be vertical or horizontal depending on your space requirements. Vertical systems require less trenches than a horizontal system and reduces disturbance to your landscaping. It is commonly utilized in areas with shallow soil depths, or where existing landscaping must be preserved.

Regardless of the type of ground loop system you choose, it is important to choose a reliable installer. It is essential to have a well-functioning and well-designed system, as geothermal systems use a significant amount of energy. A well-designed installation will ensure the longevity of your geothermal system and will save you money on electricity bills in the long run. It is crucial to flush the system frequently to remove any minerals which could affect the flow and effectiveness of the liquid used to transfer heat.

Vertical Loop

Geothermal energy is the energy from the Earth that is utilized to heat and cool buildings. This energy can be harnessed by underground loops that absorb heat and then transfer it to your building. The most common kind of geothermal system is called vertical ground loop. This kind of system is typically utilized in commercial and residential applications. The heat pump in this system captures the heat energy from the ground and transfers it to your office or home. In summer, it operates in reverse to provide cooling.

The heat energy that is transferred from the ground to your home is stored in a series of buried pipes. These pipes are an essential part of any geo-thermal hvac system. The pipes are made of high-density polyethylene. They circulate a mixture of water and propylene glycol, which is a food-grade antifreeze through the system. The temperature of soil or water stays fairly constant for within a few feet of the surface. The closed-loop geothermal system is more efficient than other heating methods, such as gas boilers and furnaces.

These loops can be placed in a horizontal trench or inserted into boreholes that are dug to a depth of 100 to 400 feet. Horizontal trenches work best for large estates with lots of land vertical boreholes are suitable for homes and businesses with limited space. Installation of a horizontal ground-loop involves digging trenches, which can take a considerable amount of time and effort. The ground must be compacted in order to ensure that the loops are securely connected to the soil.

A vertical loop system is simpler to set up than a horizontal field. The technician digs holes of 4 inches in diameter, spaced about 20 feet apart. He then connects the pipe to form an enclosed circuit. The number of holes required will be determined by your building’s dimensions and energy requirements.

It is vital to maintain the loop fields in order to keep your geothermal system running at its top efficiency. This involves cleaning the loop fields and conducting periodic testing for bacteriological issues.

Horizontal Loop

Geothermal heat pump transfers energy between your home, the ground, or a nearby body of water instead of the air outside. The reason for this is that the temperatures of the ground and water is relatively constant, unlike outdoor air temperatures which fluctuate. There are four main kinds of geothermal heating loops and the one your system uses depends on the size of your property and layout. The type of loop used and the method used to install it determine the efficiency and effectiveness of your geothermal system.

Horizontal geothermal systems use a series horizontal pipes buried in trenches between four and six feet deep. The trenches are designed to hold two to three pipe circuits. The pipe circuits are connected to a manifold, which is the central control unit. The manifold is a conduit for heated or cooled water to your home’s heating or cooling ductwork.

Initially the piping systems were installed in vertical trenches which required a larger area to cover the pipes. As technology advanced and technology improved, it was discovered that layering a single longer pipe back and forth different depths in smaller trenches could reduce space requirements and costs without the loss of performance. This led to the development of the “slinky method” of installing horizontal geothermal circuits.

In situations where there’s not enough space, a vertical ground loop can be an ideal alternative. It is also an option for homes situated in urban areas, where topsoil is thin and there is little if any space for horizontal loops. If your home is in an earthquake-prone region and cannot support the horizontal loop, a vertical loop system might be the best option.

If you have lots of water in your home lakes, ponds or ponds could be an excellent alternative for your home. 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 using a pond or lake loop will not function in the event of a power outage. Installing a backup generator will supply electricity during this time.

Desuperheater

Geothermal heating and cooling is a highly efficient alternative to traditional methods. When it comes to making the switch homeowners must consider balancing upfront costs and total savings on energy. There are many factors to consider, including the soil composition and local climate. But one of the biggest choices is whether to put in ground loops or use an external hot water tank. The latter option is more affordable, but it may not offer the same efficiency.

A desuperheater transfers heat from geothermal heating systems to your domestic hot water tank. It is designed to operate in the winter when the system’s cooling cycle produces excess heat. The desuperheater eliminates this waste heat and utilizes it to improve the efficiency of your heating system. It lowers your energy use by using pre-existing resources.

The best design of a desuperheater is dependent on a variety of physical geometric, thermal, and factors. These include the temperature of the spray water, the angle of injection, as well as the design of the nozzle. These are all important elements that impact the operation and performance of the desuperheater.

In the summer months, desuperheaters can help save up to 80 percent more in a climate with a high degree of heating than traditional hot water heaters. This is because the desuperheater makes use of the energy removed from the house in the cooling process and converts it into useful heat for the hot water generator. This allows the geothermal system to produce domestic hot water for 3 to 5 months of the year at a fraction of the cost of other energy sources.

The desuperheater also helps in winter when the geothermal system is running at its lowest capacity. The device can add the additional heat generated by the cooling system to the domestic hot-water tank. This enables the domestic hot water tank to utilize this energy for free and increases the heating capacity of the system. The desuperheater could be used to decrease the time that the geothermal system is in operation in a climate with a high degree of heating.
