Geothermal HVAC

Geothermal is a dual-purpose system that can provide both cooling and heating. The temperature of the earth below the surface is 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 different parts that make up this energy-efficient system.

Ground Loop

The Ground Loop is crucial to the efficiency and durability of geothermal heating and cooling system. It is made up of pipes that can be drilled or trenched in the yard to connect with your home’s heat pumps. The pipes are then filled with a water-based fluid that circulates to absorb or disperse heat in accordance with the needs of your home. The temperature of the ground is relatively constant between four and six feet below surface level, which makes it a great energy source for geothermal systems.

When the system is heating, the liquid used to transfer heat absorbs heat from the earth. It then carries the heat to the heat pump inside your home. The fluid is then pushed back into the loop, where it starts to circulate again. In cooling mode, the system employs the opposite method to eliminate the heat that is left and return it back to the loop, where it begins another cycle.

In a closed-loop system the piping is filled with a product based on water and then buried beneath. The solution is safe for the environment. It is not a pollutant to underground water supplies. The system can also use a pond or lake to provide heat transfer fluid, which is even more eco-friendly.

Depending on the available space depending on the space available, open and closed systems can be set up either vertically or horizontally. The vertical system requires fewer trenches than horizontal systems and reduces disturbance to your landscaping. It is typically employed in areas with low soil depths or in areas where existing landscaping needs to be preserved.

It is essential to choose a reliable installer regardless of the type of system. It is essential to have an efficient and well-designed system, since geothermal systems use a lot of energy. A quality installation will ensure the durability of your system and help you save money on electricity in the long-term. It is essential to flush the system regularly to remove any minerals which could affect the efficiency and flow of the liquid used to transfer heat.

Vertical Loop

Geothermal energy comes from the Earth and is used to heat or cool buildings. It is harnessed using a series of underground loops which absorb the thermal energy and transfer it to the building. The most commonly used type of geothermal system is called vertical ground loop. This type of geothermal system is used most often in commercial and residential settings. The heat pump in this system takes the thermal energy from the ground and carries it to your office or home. In the summer it reverses to provide cooling.

The pipes that are buried store the thermal energy that flows from the earth to your building. These pipes are a crucial element in any geo-thermal hvac system. The pipes are made of high-density polyethylene and circulate an emulsion of water and propylene glycol, which is a food-grade antifreeze, through the system. The temperature of soil or water is almost constant just only a few feet below the surface. The closed-loop geothermal system is more efficient than other heating methods, such as gas boilers and furnaces.

The loops can be erected in a horizontal trench or placed into boreholes that are made to a depth of 100 to 400 feet. Horizontal trenches are generally used for larger homes with a lot of available land, while vertical boreholes are best suited for businesses or homes that have small spaces. The process of installing horizontal ground loops entails digging extensive trenches that can take a considerable amount of time and effort. The ground must also be compacted in order to ensure that the loops are firmly connected to the soil.

A vertical loop system is much easier to install than a horizontal field. The technician digs holes of 4 inches in diameter, separated by 20 feet. He then connects the pipe to form an enclosed circuit. The number of holes needed will depend on the size of your structure and the energy demands.

To keep your geothermal cooling and heating system operating at peak performance, it is important to properly maintain the loop fields. This means cleaning the loop fields as well as performing 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. This is due to the fact that temperatures in the ground and in the water remain relatively stable, in contrast to the fluctuating outdoor air temperature. There are four primary types of geothermal heating loops, and which one you use will depend on the size of your property and layout. The type of loop and the method of installation used 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 are four to six feet deep. The trenches can accommodate up to three pipe circuits. The pipe circuits are connected to an amanifold that is the central control unit of geothermal heat pumps. The manifold sends heated or cooled water to your home’s heating or cooling ductwork.

Initially, these piping systems were placed in vertical trenches that required a larger amount of land to encase them. As technology improved it was realized that laying a larger single pipe back and forth at different depths within shorter trenches reduced costs and space requirements without losing performance. This led to the development of the “slinky method” of installing horizontal geothermal circuits.

In cases where there isn’t enough space, a vertical ground loop system is an ideal alternative. It can also be an option for homes located in urban settings, where the topsoil is a bit thin and there is little if any space for horizontal loops. Vertical loops can be a good option when your property is located in an earthquake-prone region and is not able to support the horizontal loops.

A geothermal pond or lake pump is the best option for your home if you have access to plenty of water. This kind of system functions similar to vertical or horizontal ground loop geothermal heat pumps, except the water is used to heat and cooling, not the earth. It’s important to remember that a system that utilizes lake loops or ponds will not function in the event of a power failure. Installing a backup generator will provide electricity during this period.

Desuperheater

Geothermal heating and cooling is a highly efficient alternative to traditional methods. However, when making the switch homeowners must weigh upfront costs against the total savings on energy. Many factors are involved including the soil’s composition and local climate. One of the most important choices is whether or not to put in ground loops, or install an external tank to store hot water. The latter is less expensive, but it might not offer as much efficiency.

A desuperheater is an equipment used to transfer heat from a geothermal system to your domestic hot water tank. It is designed to function in the winter when the cooling process of the system produces excess heat. The desuperheater uses this waste heat to boost the heating efficiency of your home. It also reduces the energy use by using existing sources.

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

During the summer, desuperheaters can save up to 80 percent in a climate that is dominated by heating than traditional hot water heaters. The desuperheater converts the energy removed from the house during the cooling process into heat for the hot-water generator. This enables the geothermal system to produce domestic hot water for 3 to 5 months of the year, at only a fraction of the cost of other energy sources.

The desuperheater also helps in winter when a geothermal system is operating at its smallest capacity. The device removes the extra heat generated by the cooling system and adds it to the domestic hot water tank. This enables the domestic hot water tank to use the energy that is free, and increases the heating capacity of the system. The desuperheater may also be used to decrease the time that the geothermal system is in operation in a heating dominated climate.
