Geothermal HVAC

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

Geothermal systems are made up of a heatpump, underground loops, and a distribution system. Learn more about the various components of 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 slit in the yard to connect to your home’s heat pumps. The piping is then filled with a solution containing water that circulates to absorb or disperse heat according to the needs of your home. The temperature of the ground is relatively constant between four and six feet below surface level, making 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 in your house. The fluid is then pushed back to the loop where it begins circulating again. In cooling mode, it utilizes the reverse process to remove the heat that is not needed. It returns it back to the loop in order to begin a new cycle.

In closed loop systems, the pipe is filled with a water-based solution and placed in the ground. The solution is safe and non-toxic for the environment. It is not a pollutant to underground water supplies. The system can also make use of lakes or ponds as a source of heat transfer fluid, which is more environmentally friendly.

Open and closed systems can be horizontal or vertical depending on the space you require. Vertical systems require less trenches than horizontal systems and minimizes disturbance to your landscaping. It is typically used in areas with shallow soil depths, or where existing landscaping needs to be maintained.

No matter what type of ground loop system you choose, it is essential to select a reliable installer. It is important to have an efficient and well-designed system as geothermal systems use a lot of energy. A quality installation ensures the longevity of your geothermal system and saves you money on electricity bills in the long run. It is also crucial to have the system flushed frequently to eliminate any mineral buildup, which could hinder the flow of the heat transfer fluid and reduce the efficiency of the system.

Vertical Loop

Geothermal energy originates from the Earth and is used to heat or cool buildings. It is a source of energy that can be harnessed by underground loops that absorb thermal energy and transfer it to your building. The most common type of geothermal system can be known as vertical ground loop. This type of system is most commonly utilized in commercial and residential applications. The heat pump in this system captures the heat energy from the ground and transfers it to your home or office. In the summer it reverses to provide cooling.

The heat energy that is transferred from the ground to your building is stored in a network of underground pipes. These pipes are a crucial element of any geo thermal hvac system. The tubes are made of high-density polyethylene and circulate an emulsion of propylene glycol and water, which is a food-grade antifreeze, through the system. The temperature of soil or water stays fairly constant for only 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 and boilers.

The loops can be inserted into an excavation horizontally or into boreholes that are drilled from 100 to 400 feet deep. Horizontal trenches are ideal for large properties with lots of land, while vertical boreholes are ideal for businesses and homes with small spaces. Installing a horizontal ground loop involves digging trenches, which can take a lot of time and effort. The ground must also be compacted to ensure that the loops are securely connected to the soil.

On the other the other hand vertical loop systems can be constructed quicker and with less effort than a horizontal loop field. The service technician digs holes that are 4 inches in diameter and about 20 feet apart, and then installs the piping to create a closed loop. The number of holes required will be determined by your building’s dimensions and energy requirements.

To keep your geothermal cooling and heating system at peak performance, it is important to maintain the loop fields. This includes cleaning up debris and conducting regular bacteriological testing.

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 ground and water temperatures remain relatively stable, compared to the fluctuating temperature of outdoor air. The size and layout of your property will determine the type of loop you make use of. The type of loop that is used and the method of installation determine the efficiency and effectiveness your geothermal system.

Horizontal geothermal systems make use of series of horizontal pipes, which are placed in trenches that are between four and six feet in depth. The trenches are designed to accommodate three to four pipe circuits. The pipe circuits are connected to a manifold which is the central control unit. The manifold pumps heated or chilled water into your home’s cooling or heating ductwork.

Originally these pipes were installed in vertical trenches, which required more land space to surround the pipes. As technology developed, it was discovered that layering a single pipe back-and-forth in varying depths within shorter trenches reduced space requirements and cost without necessarily losing performance. This is the reason for the “slinky” method of installing horizontal geothermal loops.

In situations where there’s not enough space, a vertical ground loop system can be an option. It’s also a great alternative for homes in urban areas, in areas where the topsoil layer is thin and there isn’t enough space for horizontal loops. If your property is located in an earthquake-prone zone and cannot support an horizontal loop system, the vertical loop may be the best option.

A geothermal lake or pond heat pump system can be the ideal option for your home when you have access to plenty of water. This kind of system operates similar to vertical or horizontal ground loop geothermal heat pumps, but the water is used to heat and cooling, instead of the earth. Keep in mind that a geothermal loop system that utilizes lakes 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 consider balancing upfront costs against total savings on energy. There are many factors to consider, including the soil composition and local climate. But one of the biggest decisions is whether to bury ground loops or use an external hot water tank. The latter option may be cheaper, but it might not offer the same efficiency.

A desuperheater is a piece of equipment used to transfer heat from a geothermal source into your hot water tank in your home. It is designed to function in winter when the cooling cycle of the system produces excess heat. The desuperheater uses this waste heat to improve the efficiency of heating in your home. It lowers your energy use by using existing resources.

The optimal design of a desuperheater is dependent on a variety of physical, geometric, and thermal variables. These include the injection angle, the temperature of the water spray, and the nozzle’s design. These are all crucial aspects that affect the performance and operation of the desuperheater.

In a climate that is dominated by heating, a desuperheater could save you as much as 80percent more than a traditional water heater in the summer. This is because the desuperheater uses the energy that is emitted from the house during the cooling process and converts it into useful heat for the hot water generator. This allows the geothermal system to make domestic hot water for three months of the year, at a fraction of the cost of other energy sources.

The desuperheater also comes in handy in the winter, when the geothermal heating system is operating at its lowest 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 this free energy and maximizes the heating capacity of the system. The desuperheater can even be used to cut down on the length of time geothermal systems are in operation in a heating dominated climate.
