Geothermal HVAC

In contrast to 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 remain pretty constant all year.

A geothermal system is comprised of an underground heat pump, 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 vital to the effectiveness and longevity of geothermal cooling and heating system. It is comprised of pipes that are either placed in the backyard and connected to the heat pump in your home. The pipes are then filled with a water-based fluid that circulates to absorb or disperse heat based on your home’s needs. The temperature of the ground stays constant between four and six feet below the surface, making it an ideal 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 then transfers it to the heat pump within your house. The fluid is then pushed into the loop, where it starts circulating again. In cooling mode, the system utilizes the reverse process to remove the excess heat and return it back to the loop, where it begins another cycle.

In a closed-loop system, the piping is filled with a solution made of water, and then buried underground. The solution is safe and not harmful to the environment, and it does not pollute the water supply in underground. The system can also utilize the pond or lake as a source of heat transfer fluid, which is more eco-friendly.

Based on the space available, closed and open systems can be installed either vertically or horizontally. The vertical system requires fewer trenches than a horizontal one and minimizes disturbance to your landscaping. It is ideal for areas where soil depths are low or in areas where existing landscaping must be maintained.

It is crucial to choose an experienced installer regardless of the kind of system. Geothermal systems require large 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 long-term viability of your system and help you save money on electricity over the long term. It is also essential to flush the system regularly to remove any mineral buildup that could hinder the flow of the heat transfer fluid and reduce the efficiency of the system.

Vertical Loop

Geothermal energy is the energy derived from the Earth that is used to cool and heat buildings. The energy is harnessed using a series of underground loops which absorb the thermal energy and transmit it to your building. Vertical ground loops are the most common geothermal system. This type of system is most commonly employed in commercial and residential applications. The heat pump in this system takes the heat energy from the ground and transfers it 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 series of underground pipes. These pipes are an essential part of any geo-thermal HVAC system. The pipes are made of high-density Polyethylene and circulate water as well as propylene glycol, which is food-grade antifreeze. The temperature of the soil or water stays relatively constant at only a few feet beneath the surface. This enables the closed-loop geothermal heat pump to work more efficiently than other heating systems, like gas furnaces and boilers.

The loops can be placed in a trench horizontally or inserted in boreholes that are drilled from to 400 feet deep. Horizontal trenches work best for large properties with lots of land vertical boreholes are suitable for homes and businesses with limited space. The process of installing horizontal ground loops entails digging a long trench that may take a considerable amount of time and effort. Additionally the ground has to be compacted to ensure that the loops have a strong grip on the soil.

On the other side vertical loop systems can be constructed much more quickly and easily than a horizontal loop field. The technician drills holes of 4 inches in diameter spaced 20 feet apart. He then installs the pipe to create a closed circuit. The number of holes needed will depend on the size of your structure and the energy requirements.

To keep your geothermal cooling and heating system at peak performance, it is important to maintain the loop fields. This means removing any debris and conducting regular tests for bacteriological health.

Horizontal Loop

Geothermal heat pumps transfer energy between your home and ground or a nearby body of water, rather than being able to draw energy from the air outside. This is due to the fact that ground and water temperatures remain relatively stable, unlike the fluctuating outdoor air temperature. The dimensions and layout of your property will determine which loop to use. The type of loop used and the method of installation employed determine the efficiency and effectiveness of your geothermal heating system.

Horizontal geothermal systems employ series of horizontal pipes that are placed in trenches that are between four and six feet in depth. The trenches can house up to three pipe circuits. The pipe circuits are connected into the manifold, which is the central control unit of the geothermal heat pumps. The manifold then delivers chilled and heated water to your home’s heating and cooling ductwork.

In the beginning, these piping systems were installed in vertical trenches, which required a larger amount of land to cover them. As technology improved, it was found that laying a single, longer pipe back and forth at different depths in smaller trenches could decrease the amount of space needed and also costs without sacrificing performance. This was the birth of the “slinky” method of constructing horizontal geothermal loops.

A vertical ground loop system is a good alternative to horizontal geothermal heat pump system in situations where there isn’t enough land available. It is also an option for homes in urban settings, where topsoil is thin and there isn’t any room for horizontal loops. A vertical loop system could also be the best solution when your property is located in an earthquake-prone area and cannot be supported by a horizontal system.

A geothermal lake or pond heat pump system can be the ideal option for your home if you have access to plenty of water. This kind of system operates exactly like a vertical or horizontal ground loop geothermal heat pump, but the water is used to heat and cooling instead of the earth. Keep in mind that the geothermal loop system that is based on a lake or pond will not function in the event of a 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. When it comes time to switch homeowners must consider balancing the initial costs with the total savings on energy. Many factors are involved such as the soil’s composition and local climate. One of the most important decisions is whether or not to put in ground loops, or install an external tank for hot water. The latter is less expensive, but may not offer the same efficiency.

A desuperheater can be described as a piece of equipment used to transfer 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 utilizes this wasted heat to boost the heating performance of your home. It can also cut down on your energy usage by utilizing existing resources.

The ideal design of a desuperheater dependent on a variety of physical geometric, thermal, and variables. These variables include the spray water temperature as well as the angle of injection, as well as the design of the nozzle. These are all important factors that affect the desuperheater’s operation and performance.

During the summer, desuperheaters can save up to 80 percent in a climate that is dominated by heating than a conventional hot water heater. This is because the desuperheater makes use of the energy emitted by the house during the cooling process and converts it into useful heat for the hot water generator. The geothermal system can provide domestic hot water for 3 to 5 months of the year at a fraction the cost of alternative energy sources.

The desuperheater also helps in winter when geothermal systems are running at its lowest capacity. The device can add the additional heat produced by the cooling system to the domestic hot water tank. This allows the hot water tank to utilize the energy that is free and boosts the heating capacity of the system. The desuperheater could be used to cut down on the amount of time a geothermal system is active in a climate with a high degree of heating.
