Geothermal HVAC

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

A geothermal system is made of a heatpump, underground loops, and a distribution system. Find out more about this energy-efficient system’s components:.

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 then connected to your home’s heat pump. The pipes are then filled with a water-based solution that circulates to absorb or disperse heat according to the needs of your home. The temperature of the ground is constant between four and six feet below the surface level, making it an ideal energy source for geothermal systems.

When the system is in heating mode, the heat transfer fluid absorbs the Earth’s heat and then transfers it to the heat pump in your home. The fluid is then pushed back into the loop, where it starts circulating again. In cooling mode, it employs the reverse process to remove the excess heat. It then returns to the loop to start another cycle.

In a closed loop system the piping is filled with a water-based product and placed in the ground. 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 as the source of heat transfer fluid, making it more eco-friendly.

Open and closed systems can be vertical or horizontal depending on your space requirements. Vertical systems require less trenches and cause less disturbance to your landscaping than horizontal systems. It is often employed in areas with low soil depths or where existing landscaping needs to be maintained.

Regardless of the type of ground loop system, it is important to choose an experienced installer. Geothermal systems require substantial amounts of energy to operate, and it is crucial to have a well-designed and efficient system in place. A well-designed installation will ensure the durability of your system, and will help you save money on electricity in the long-term. It is crucial to flush the system frequently to eliminate any minerals that could reduce the efficiency and flow of the heat transfer liquid.

Vertical Loop

Geothermal energy originates from the Earth and is utilized to cool or heat buildings. It is a source of energy that can be harnessed using underground loops that absorb thermal energy and then transfer it into your building. The most commonly used type of geothermal system can be called vertical ground loop. This kind of system is commonly used in residential and commercial applications. This system uses an energy pump to transfer heat from the earth to your home or office. In the summer, it operates in reverse to provide cooling.

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

These loops can either be installed in the horizontal direction of a trench or placed in boreholes drilled from 100 to 400 feet deep. Horizontal trenches are usually used for larger properties with a lot of available land, while vertical boreholes are ideal for businesses or homes that have small spaces. The process of installing horizontal ground loops entails digging extensive trenches that can require considerable time and effort. Additionally, the ground must be compacted to ensure the loops have a strong hold on the soil.

On the other the other hand vertical loop systems can be constructed much more quickly and easily than a horizontal loop field. The service technician digs holes that are 4 inches in diameter and about 20 feet apart, then installs the piping to create an enclosed loop. The number of holes needed will depend on the size of your building and the energy demands.

It is vital to keep the loop fields in good condition to keep your geothermal system operating at its peak. This includes removing debris and conducting regular bacteriological testing.

Horizontal Loop

Geothermal heat pumps transfer energy between your home and ground or the nearby body of water, instead of taking energy from the outside air. This is due to the fact that ground and water temperatures remain relatively stable, unlike the fluctuating outdoor temperature. There are four main kinds of geothermal heating loops, and which one you use will depend on the size of your property as well as its layout. The type of loop used and the installation method used determine the efficiency and effectiveness of your geothermal heating system.

Horizontal geothermal systems employ series horizontal pipes placed in trenches that are between four and six feet in depth. The trenches are designed to hold two to three pipe circuits. The pipe circuits are connected to a manifold which is the geothermal heat pump’s central control unit. The manifold is then able to send chilled and heated water to your home’s cooling and heating ductwork.

In the beginning the pipes were installed in vertical trenches which required a larger space to surround the pipes. As technology advanced, it was discovered that layering a single pipe back-and-forth in varying depths within smaller trenches could reduce space requirements and cost without sacrificed performance. This led to the invention of the “slinky method” of installing horizontal geothermal circuits.

In cases where there isn’t enough land available, a vertical loop system is an ideal alternative. It can also be an option for homes located in urban settings, in which the topsoil is scarce and there isn’t any space for horizontal loops. A vertical loop system could be a good option for properties that are located in an earthquake-prone area and cannot support an horizontal loop.

If you have plenty of water lakes or ponds can be the ideal alternative for your home. This kind of system is similar to a horizontal or vertical ground loop geothermal heating system however instead of using earth to heat and cool, the water is used. Be aware that a geothermal loop system using lakes or ponds cannot function in the event of a power failure. Installing a backup generator can supply electricity during this time.

Desuperheater

Geothermal heating is a cost-effective alternative to conventional methods. When it comes to making the switch homeowners must consider balancing upfront costs and energy savings in the long run. There are a myriad of aspects to consider including the local climate and soil makeup. One of the most important decisions is whether or not to put in ground loops or to use an external tank to store hot water. The latter option may be less expensive, however it won’t provide as much efficiency.

A desuperheater is a device that transfers heat from a geothermal heating system to your domestic hot water tank. It is designed to work in the winter when the system’s cooling cycle produces heat that is not needed. The desuperheater uses this waste heat to increase the efficiency of heating in your home. It helps reduce your energy consumption by using pre-existing resources.

The optimum design for a desuperheater depends on several physical, thermal, and geometric variables. These include the injection angle, temperature of the spray water, and the nozzle design. These are all important aspects that affect the operation and performance of the desuperheater.

In a climate that is dominated by heating, a desuperheater can save you as much as 80% more than an ordinary water heater during the summer. The desuperheater converts the energy that is removed from the home through cooling into heat for the hot-water generator. Geothermal systems can provide hot water to homes for 3 to 5 months a year for a fraction of the cost of other energy sources.

The desuperheater also helps in winter when geothermal systems are operating at its lowest capacity. The device eliminates the excess heat produced by the cooling system and adds it to the domestic hot water tank. This allows the hot water tank to utilize this energy free of charge and increase the heating capacity of the system. The desuperheater could be used to cut down on the length of time geothermal systems are in operation in a heating dominated climate.
