Geothermal HVAC

In contrast to traditional HVAC systems that operate on natural gas, fuel oil, propane or electricity, geothermal provides two-in-one heating and cooling. The temperature of the earth below the surface is fairly constant throughout the year.

A geothermal system consists of a heat pump, underground loops and a distribution network (such as air ducts). Find out more about this energy-efficient system’s components:.

Ground Loop

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

When the system is in heating mode in the heating mode, the heat transfer fluid absorbs the heat from the earth and carries it to the heat pump in your home. The fluid is then transferred to the loop which then starts to circulate. In cooling mode, the system utilizes the reverse process to remove the heat surplus and return it to the loop, where it starts another cycle.

In a closed loop system the pipe is filled with a water-based product and placed in the ground. The solution is safe and non-toxic for the environment. It does not pollute underground water supplies. The system can also make use of a pond or lake to provide heat transfer fluid, making it more sustainable.

Open and closed systems can be horizontal or vertical, depending on the space you require. Vertical systems require less trenches and cause less disturbance to your landscaping than horizontal systems. It is often utilized in areas with shallow soil depths or where existing landscaping must be preserved.

It is important to select a reliable installer regardless of the type of system. Geothermal systems require large amounts of energy to run and it is vital to have an efficient and well-designed system in place. A well-designed installation will ensure the longevity of your geothermal system and saves you money on electric bills in the long term. It is also essential to flush the system frequently to eliminate any mineral buildup that could hinder the flow of heat transfer fluid and impede system efficiency.

Vertical Loop

Geothermal energy is the energy that comes from the Earth that is utilized to heat and cool buildings. The energy is harnessed using underground loops that absorb the thermal energy and then transfer it to your building. The most commonly used type of geothermal system is called a vertical ground loop. This kind of geothermal system is commonly used in commercial and residential applications. The system utilizes the heat pump to transfer energy 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 building is stored in a series of underground pipes. These pipes are an essential component of any geo thermal hvac system. The pipes are made of Polyethylene with high density and circulate water and propylene glycol which is food-grade antifreeze. The temperature of the water or soil stays relatively constant, even a few feet below the surface. This allows the closed-loop geothermal heat pump to work more efficiently than other heating systems like gas furnaces or boilers.

The loops can be installed in a trench horizontally or inserted in boreholes drilled from 100 to 400 feet deep. Horizontal trenches work best for large homes with lots of land, whereas vertical boreholes work well for homes and businesses with limited space. The installation process for a horizontal ground loop involves digging large trenches that take a lot of time and effort. The ground must be compacted to ensure that the loops remain attached to the soil.

A vertical loop system is much easier to install than a horizontal field. The service technician drills holes that are 4 inches in diameter and approximately 20 feet apart, and installs the piping to create an enclosed loop. The number of holes required will be determined by your building’s size and energy requirements.

It is essential to keep the loop fields in good condition to keep your geothermal system operating at its top efficiency. This includes cleaning the loop fields and performing periodic tests for bacteriology.

Horizontal Loop

Geothermal heat pump transfers energy between your home, the ground or a nearby body water instead of the air outside. This is because ground and water temperatures remain relatively stable, unlike the fluctuating temperature of outdoor air. The size and layout of your property will determine which loop you use. The type of loop you choose and the installation method used determine the effectiveness and efficiency of your geothermal heating system.

Horizontal geothermal heat pump systems utilize a series of pipes buried horizontally in trenches that are four to six feet deep. The trenches are designed to accommodate two to three pipe circuits. The pipe circuits are connected to a manifold which is the central control unit of geothermal heat pumps. The manifold is a conduit for heated or cooled water to your home’s cooling or heating ductwork.

Initially, these piping systems were placed in vertical trenches that required a larger area of land to cover them. As technology improved, it was discovered that laying a larger single pipe back-and-forth in varying depths within smaller trenches could reduce space requirements and cost without necessarily sacrificed performance. This was the beginning of the “slinky” method of installing horizontal geothermal loops.

A vertical ground loop system is a good alternative to horizontal geothermal heat pump system in cases where there is not enough land available. It’s also a good option for homes located in urban areas in areas where the topsoil layer is thin and there isn’t enough space for horizontal loops. A vertical loop system can also be the best solution when your property is located in an earthquake-prone area and is not able to support a horizontal system.

A geothermal pond or lake pump system can be the ideal option for your home in the event that you have access an abundance of water. This kind of system is similar to a horizontal or vertical ground loop geothermal heating system however, instead of using earth for cooling and heating it uses water to heat and cool. It is crucial to note that a geothermal system that uses lake loops or ponds will not work in the event of a power outage. A backup generator should be installed to supply a source of electricity during this time.

Desuperheater

Geothermal cooling and heating is a highly efficient alternative to conventional methods. But when it comes to making the switch, homeowners must balance the initial costs with total energy savings. There are a variety of aspects to consider such as the local climate and soil’s composition. One of the most important choices is whether or not to dig ground loops or to use an external tank for hot water. The latter option is cheaper, but it may not provide the same efficiency.

A desuperheater transfers heat from geothermal heating systems to your domestic hot water tank. It is designed to function in the winter when the system’s cooling cycle generates excess heat. The desuperheater removes 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 optimal design of a desuperheater is dependent on a variety of physical, geometric, and thermal variables. These variables include the temperature of the spray water, the angle of injection, as well as the design of the nozzle. These are all elements that can influence the performance and operation of the desuperheater.

During the summer months, a desuperheater can save up to 80 percent in a climate that is dominated by heating than the conventional hot water heater. This is because the desuperheater uses the energy that is emitted from the house in the cooling process and converts it into useful heat for the hot water generator. Geothermal systems can supply domestic hot water for 3 to 5 months per year at a fraction the cost of alternative energy sources.

The desuperheater can also be useful in the winter, when a geothermal heating 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 use the energy that is free and boosts the system’s heating capacity. The desuperheater is also an excellent way to cut down on the amount of time that geothermal heating systems are operating when it’s in a location that has a large demand for heating.
