Geothermal HVAC

Geothermal is a dual-purpose system that can provide both cooling and heating. The temperatures of the earth below the surface stay fairly constant throughout the year.

Geothermal systems consist of a heatpump, underground loops and a distribution system. Learn more about the various parts that make up this energy-efficient system:.

Ground Loop

The Ground Loop is vital to the efficiency and durability of geothermal heating and cooling system. It is comprised of pipes that can be drilled or slit in the backyard to connect with your home’s heat pumps. The piping is then filled with a water-based solution that circulates to absorb or disperse heat according to your home’s needs. The temperature of the ground is constant from four to six feet below the surface, making it a natural source of energy for geothermal systems.

When the system is in heating mode, the heat transfer fluid absorbs the Earth’s heat and then carries it to the heat pump inside your house. The fluid is then returned to the loop, where it starts to circulate again. In cooling mode, the system employs the opposite method to eliminate the excess heat and return it back to the loop, where it begins another cycle.

In closed loop systems, the piping is filled with a water-based solution, and then is buried in the ground. The solution is non-toxic and safe for the environment. It is not a pollutant to underground water supplies. The system can be used to use lakes, ponds or other body of water as a source of heat transfer fluid. This is even more green.

Both closed and open systems can be horizontal or vertical according to the space you need. Vertical systems require fewer trenches than horizontal systems and is less disruptive to your landscaping. It is used in areas in which soil depths are low or where existing landscaping needs to be maintained.

Regardless of the type of ground loop system you choose, it is essential to select an experienced installer. It is essential to have an efficient and well-designed system, since geothermal systems use a significant amount of energy. A well-designed installation will ensure the longevity of your geothermal system, and will save you money on electricity bills in the long run. It is also critical to flush the system frequently to eliminate any mineral buildup that can reduce the flow of heat transfer fluid and impede the efficiency of the system.

Vertical Loop

Geothermal energy is the energy derived from the Earth that is used to heat and cool buildings. It can be harnessed through underground loops that absorb thermal energy and transfer it into your building. Vertical ground loops are the most popular geothermal system. This type of geothermal system is used most often in commercial and residential applications. This system makes use of an energy pump to transfer heat from the earth into your home or office. In the summer, it reverses to provide cooling.

The thermal energy transferred from the ground to your building is stored in a network of buried pipes. These pipes are a crucial part of any geo-thermal hvac system. The tubes are made from Polyethylene with high density and circulate water as well as propylene glycol which is food-grade antifreeze. The temperature of the soil or water remains almost constant just a few feet beneath the surface. The closed loop geothermal system is more efficient than other heating methods such as gas boilers and furnaces.

The loops can be placed in a trench horizontally or inserted in boreholes drilled from 100 to 400 feet deep. Horizontal trenches are ideal for large homes with lots of land, whereas vertical boreholes work well for businesses and homes with little space. The process of installing horizontal ground loops entails digging a long trench that may take a lot of time and effort. Additionally the ground has to be compacted to ensure the loops are able to hold a solid hold on the soil.

A vertical loop system is much simpler to set up than a horizontal field. The technician digging holes that are 4 inches in diameter and 20 feet apart, and installs the piping in order to create a closed loop. The number of holes required will depend on the size of your structure and the energy needs.

To keep your geothermal cooling and heating system running at its peak, it is important to properly maintain the loop fields. This involves cleaning the loop fields and conducting periodic tests for bacteriology.

Horizontal Loop

Geothermal heat pumps transfer energy between your home and the ground or the nearby body of water, instead of being able to draw energy from 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. There are four major types of geothermal heating loops, and the one you use will depend on your property size and layout. The type of loop you choose and the method of installation used determine the effectiveness and efficiency of your geothermal heating system.

Horizontal geothermal systems employ series of horizontal pipes, which are buried in trenches between four and six feet deep. The trenches can hold up to three pipe circuits. The pipe circuits are connected to a manifold which is the central control unit for geothermal heat pumps. The manifold sends heated or chilled water into your home’s heating or cooling ductwork.

Initially the piping systems were installed in vertical trenches, which required more land area to encase the pipes. As technology improved, it was found that laying a single, longer pipe back and forth different depths in smaller trenches could reduce space requirements and costs without losing 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 for situations in which there isn’t enough land space available. It is also a good option for homes located in urban areas where the topsoil is a bit thin and there isn’t much space for horizontal loops. Vertical loops can be the ideal solution when your property is located in an earthquake-prone region and cannot be supported by a horizontal system.

A geothermal pond or lake pump is the best option for your home in the event that you have access plenty of water. This kind of system is similar to a horizontal or a vertical ground loop geothermal heating system however instead of using earth to heat and cool the water is used. It is important to keep in mind that a geothermal system that uses lakes 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 heating and cooling is a highly efficient alternative to traditional methods. However, when switching to geothermal, homeowners must balance the initial costs with total energy savings. There are many factors to consider, including the soil composition and local climate. One of the most important decisions is whether or not to dig ground loops, or install an external tank to store hot water. The latter option is more affordable, but it may not provide the same level of efficiency.

A desuperheater transfers heat from a geothermal heating system to your home hot water tank. It is designed to operate during winter, when the cooling process of the system produces excess heat. The desuperheater utilizes this wasted heat to increase the heating efficiency of your home. It reduces your energy usage by using resources already in use.

The optimal design of a desuperheater depends on several physical, thermal, and geometric variables. These factors include the angle of injection, the temperature of the spray water, and the nozzle’s design. These are all factors that can affect the performance and efficiency of the desuperheater.

During the summer months, desuperheaters can save up to 80 percent more in a climate with a high degree of heating than the conventional hot water heater. The desuperheater converts the energy removed from the home during cooling into heat for the hot water generator. This enables the geothermal system to produce domestic hot water for 3-5 months of the year, at a fraction of the cost of other energy sources.

The desuperheater can also be useful in winter, when the geothermal heating system is at its lowest capacity. The device takes away the extra 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. Desuperheaters are also an excellent way to cut down on the amount of time geothermal heating systems are in use when it’s in a location with a high heating demand.
