Geothermal HVAC

Geothermal is a two-in-one system that provides cooling and heating. The temperature of the earth beneath the surface is relatively constant throughout the year.

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

Ground Loop

The Ground Loop is essential to the efficiency and durability of geothermal cooling and heating system. It is made up of pipes that can be drilled or trenched in the backyard to connect to your home’s heat pumps. The piping is filled with a water-based solution and circulated to absorb or distribute heat depending on the requirements of your home. The temperature of the ground is constant four to six feet below the surface, which makes it a natural source of energy for geothermal systems.

When the system is heating up, the liquid used to transfer heat absorbs heat from the earth. It then transmits that heat to the heat pump inside your home. The fluid is then pushed into the loop, where it starts circulating again. In cooling mode, it utilizes the opposite process to remove the heat surplus. It then returns to the loop to begin a new cycle.

In a closed loop system, the piping is filled with a water-based solution and buried in the ground. The solution is safe and non-toxic for the environment. It doesn’t pollute underground water sources. The system can also utilize lakes or ponds as the source of heat transfer fluid, making it more eco-friendly.

Depending on the space available, closed and open systems may be installed horizontally or vertically. Vertical systems require fewer trenches and cause less disturbance to your landscaping than horizontal systems. It is often used in areas with shallow soil depths, or where existing landscaping needs to be maintained.

It is essential to choose a reliable installer regardless of the kind of system. It is crucial to have a well-functioning and well-designed system, since geothermal systems use a lot of energy. A quality installation will ensure the longevity of your system and allow you to save energy costs over the long term. It is also essential to have the system flushed regularly to remove any mineral buildup. This can hinder the flow of heat transfer fluid and reduce the efficiency of the system.

Vertical Loop

Geothermal energy is the energy that comes from the Earth that is utilized to heat and cool buildings. This energy can be harnessed using underground loops which absorb thermal energy and transfer it to your building. Vertical ground loops are the most commonly used geothermal system. This kind of system is most commonly employed in commercial and residential applications. The system utilizes the heat pump to transfer heat from the earth to your home or office. In the summer it reverses to provide cooling.

The thermal energy that is transferred from the ground to your house is stored in a network of underground pipes. These pipes are a crucial part of any geo-thermal HVAC system. The tubes are made of high-density polyethylene. They circulate an emulsion of propylene glycol and water which is a food grade antifreeze, through the system. The temperature of the soil or water remains fairly 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 or boilers.

The loops can be erected in a horizontal trench, or placed into boreholes that are dug to the depth of 100- 400 feet. Horizontal trenches are usually used for larger homes with plenty of land, while vertical boreholes are ideal for homes or businesses that have limited space. The process of installing a horizontal ground loop involves digging extensive trenches that can require considerable time and effort. The ground must be compacted in order to ensure that the loops are securely connected to the soil.

A vertical loop is more straightforward to install than a horizontal field. The service technician digs holes that are 4 inches in diameter and about 20 feet apart, and installs the piping in order to create a closed loop. The number of holes you need will depend on your building’s size and energy requirements.

It is essential to maintain the loop fields to keep your geothermal system functioning at its best. This means cleaning the loop fields and performing periodic bacteriological tests.

Horizontal Loop

Geothermal heat pumps transfer energy between your house and the ground or a nearby body of water, rather than being able to draw energy from the air outside. The reason for this is that the temperatures of the ground and water is generally constant, in contrast to outdoor air temperatures which fluctuate. The dimensions and layout of your property will determine which loop to use. The type of loop used and the method of installation used determine the efficiency and effectiveness of your geothermal heating system.

Horizontal geothermal systems use a series of horizontal pipes that are buried in trenches between four and six feet in depth. The trenches can accommodate 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 is then able to send heated and cooled water to your home’s cooling and heating ductwork.

Initially, these piping systems were installed in vertical trenches, which required a larger area of land to encase them. As technology improved and technology improved, it was discovered that layering a longer single pipe back and forth at different depths within smaller trenches could reduce costs and space requirements without sacrificed performance. This was the birth of the “slinky” method of installing horizontal geothermal loops.

A vertical ground loop system is an excellent alternative to horizontal geothermal heat pump system in cases where there is not enough land available. It’s also a good alternative for homes situated in urban areas, where the topsoil is thin, and there is not much space for horizontal loops. If your property is located in an earthquake-prone region and is not able to support a horizontal loop system, a vertical loop system could be the best choice.

If you have lots of water in your home lakes, ponds or ponds could be an excellent alternative for your home. This type of system works exactly like a horizontal or vertical ground loop geothermal heat pumps, however, the water is used for heating and cooling instead of the earth. Be aware that a geothermal loop system that utilizes the pond or lake will not function in the event of power failure. Installing a backup generator can provide electricity during this period.

Desuperheater

Geothermal cooling and heating is a very efficient alternative to conventional methods. But when it comes to making the switch, homeowners must balance the initial costs with total savings on energy. Many factors are involved such as the soil’s composition and climate of the area. But one of the biggest choices is whether to put in ground loops or build an external hot water tank. The latter option is less expensive, but may not provide the same level of efficiency.

A desuperheater transfer heat from a geothermal heating system to your hot water tank. It is designed to work in the winter months when the cooling process of the system produces excess heat. The desuperheater utilizes this heat to improve the heating performance of your home. It also reduces the energy use by utilizing 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 design. These are all aspects that affect the performance and operation of the desuperheater.

In a climate dominated by heating, a desuperheater could save you up to 20% more than a traditional water heater in the summer. 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 create 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 the winter when geothermal systems are operating at its smallest capacity. The device eliminates the excess heat generated by the cooling system and transfers it to the domestic hot water tank. This allows the hot water tank to use the energy that is free and boosts the system’s heating capacity. The desuperheater may also be used to cut down on the amount of time the geothermal system is in operation in a heating dominated climate.
