Geothermal HVAC

In contrast to traditional HVAC systems that rely on natural gas, fuel oil propane, electricity or fuel oil geothermal offers two-in-one cooling and heating. The temperatures of the earth below the surface remain relatively consistent year-round.

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

Ground Loop

The Ground Loop is essential to the effectiveness and longevity of geothermal heating and cooling system. It is comprised of pipes that are trenched or drilled in the backyard and connected to your home’s heat pump. The piping is then filled with a water-based fluid that circulates to absorb or disperse heat based on the needs of your home. The temperature of the ground is relatively constant between four and six feet below the surface level, which makes it a great energy source for geothermal systems.

When the system is in heating mode the heat transfer fluid absorbs the earth’s heat and carries it to the heat pump inside your house. The fluid is then returned to the loop where it begins circulating again. In cooling mode, the system uses the opposite method to eliminate the excess heat and return it back to the loop where it starts 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 and not harmful to the environment, and doesn’t pollute the water supply in underground. The system can also make use of a pond or lake as a source of heat transfer fluid, making it more eco-friendly.

Open and closed systems can be vertical or horizontal according to the space you need. Vertical systems require less trenches and cause less disturbance to your landscaping than horizontal systems. It is often used in areas where soil depths are shallow or in areas where existing landscaping must be maintained.

Regardless of the type of ground loop system, it is crucial to select an experienced installer. It is important 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 can save your money on electricity costs in the long term. It is essential to flush the system regularly to get rid of any mineral deposits that can reduce the flow and effectiveness of the liquid used to transfer heat.

Vertical Loop

Geothermal energy is the energy derived from the Earth that is utilized to heat and cool buildings. This energy can be harnessed using underground loops which absorb thermal energy and then transfer it into your building. The most commonly used type of geothermal system can be known as vertical ground loop. This type of geothermal system is typically used in commercial and residential settings. The heat pump in this system captures the thermal energy from the ground and then transfers it to your office or home. In summer, it works in reverse to provide cooling.

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

The loops can be erected in a horizontal trench, or put into boreholes made to an average depth of 100 to 400 feet. Horizontal trenches are typically used for larger homes with lots of land available, while vertical boreholes are best suited for businesses or homes that have limited space. Installing a horizontal ground loop involves digging trenches, which could take a considerable amount of time and effort. The ground is also to be compacted in order to ensure that the loops are securely connected to the soil.

A vertical loop system is much more straightforward to install than a horizontal field. The service technician drills holes that are 4 inches in diameter and 20 feet apart, then installs the piping to form an enclosed loop. The number of holes you need will depend on the building’s size and the energy requirements.

To keep your geothermal cooling and heating system running at its peak It is essential to maintain the loop fields. This includes removing debris and conducting periodic bacteriological testing.

Horizontal Loop

Geothermal heat pumps transfer energy between your home, the ground, or a nearby body of water instead of the air outside. This is because ground and water temperatures remain relatively stable, unlike the fluctuating temperature of outdoor air. There are four main kinds of geothermal heating loops and which one you choose to use depends on your property size and layout. The type of loop that is used and the method used to install it determine the effectiveness and efficiency of your geothermal system.

Horizontal geothermal heat pump systems use 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 an amanifold that is the central control unit of geothermal heat pumps. The manifold then sends hot and cool water to your home’s cooling and heating ductwork.

Initially, these piping systems were installed in vertical trenches, which required a larger amount of land to cover them. As technology developed and technology improved, it was discovered that laying a larger single pipe back-and-forth at varying depths within shorter trenches decreased space requirements and cost without necessarily sacrificed performance. This led to the invention of the “slinky method” of installing horizontal geothermal circuits.

In cases where there isn’t enough space, a vertical ground loop system can be an option. It’s also a good alternative for homes in urban areas, where the topsoil is a bit thin and there isn’t enough space for horizontal loops. A vertical loop system could be the ideal solution for properties that are located in an earthquake-prone area and cannot be supported by a horizontal system.

If you have lots of water lakes or ponds can be a great alternative for your home. This type of system works similar to a vertical or horizontal ground loop geothermal heat pump, however, the water is used to heat and cooling, not the earth. Keep in mind that the geothermal loop system that is based on lakes or ponds will not function in the event of power failure. A backup generator should be installed to supply an electrical source during this period.

Desuperheater

Geothermal heating is a reliable alternative to conventional methods. But when making the switch, homeowners must balance the initial costs with total energy savings. There are many factors to consider including the soil’s composition and local climate. One of the most important choices is whether to put in ground loops or build an external hot water tank. The latter option may be less expensive, however it won’t provide as much efficiency.

A desuperheater is an equipment that transfers heat from a geothermal source into your hot water tank in your home. It is designed to operate in winter when the cooling process of the system generates excess heat. The desuperheater uses this waste heat to increase the efficiency of heating in your home. It reduces your energy usage by using pre-existing resources.

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

In a climate that is dominated by heating, a desuperheater will save you up to 80percent more than an ordinary water heater during the summer. The desuperheater converts the energy that is taken from the house through cooling into heat for the hot-water generator. This enables the geothermal system to create domestic hot water for 3-5 months of the year at a fraction of the cost of other energy sources.

The desuperheater is also able to help during winter, when a geothermal system is operating at its lowest capacity. The device adds the extra heat produced by the cooling system to the domestic hot water tank. This allows the hot water tank to utilize this energy free of charge and increase the system’s heating capacity. Desuperheaters are also a great way to reduce the amount of time that a geothermal heating system is in use when it’s in a climate that has a high demand for heating.
