Geothermal HVAC

Unlike traditional HVAC systems that rely on fuel oil, natural gas, propane or electricity geothermal offers two-in-one cooling and heating. The temperatures of the earth below the surface remain pretty constant all year.

Geothermal systems consist up of a heatpump, underground loops and a distribution system. Learn more about this energy-efficient system’s components:.

Ground Loop

The Ground Loop is the most important element to a geothermal system’s efficiency and longevity. It is made up of pipes that can be drilled or trenched in the backyard to connect with your home’s heat pumps. The piping will be filled with water-based solution and circulated to absorb or distribute heat based on 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 the heat transfer fluid absorbs the heat from the earth and then carries it to the heat pump inside your home. The fluid is then moved into the loop which then starts to circulate. In cooling mode, it utilizes the reverse process to remove the heat surplus. It then returns it back to the loop in order to begin another cycle.

In a closed loop system, the pipes are filled with a water-based product and is buried in the ground. The solution is safe and not harmful to the environment, and it does not affect the water supply of underground. The system can also utilize a pond or lake to provide heat transfer fluid, making it more eco-friendly.

Open and closed systems can be vertical or horizontal, according to the space you need. Vertical systems require fewer trenches than a horizontal one and minimizes disturbance to your landscaping. It is typically utilized in areas with shallow soil depths, or where existing landscaping needs to be maintained.

It is important to select a reliable installer regardless of the kind of system. It is essential to have a well-functioning and well-designed system, as geothermal systems use a lot of energy. A quality installation ensures the longevity of your geothermal system, and can save you money on electric bills in the long term. It is crucial to flush the system regularly to eliminate any minerals which could affect the flow and efficiency of the liquid used to transfer heat.

Vertical Loop

Geothermal energy is derived from the Earth and is used to heat or cool buildings. It is a source of energy that can be harnessed using underground loops which absorb thermal energy and transfer it into your building. Vertical ground loops are the most popular geothermal system. This type of system is commonly utilized in commercial and residential applications. The heat pump in this system absorbs the heat energy from the ground and then transfers it to your office or home. In the summer, it works in reverse to provide cooling.

The heat energy that is transferred from the ground to your home is stored in a set of underground pipes. These pipes are a crucial part of any geo-thermal hvac system. The tubes are made from high-density Polyethylene and circulate water and propylene glycol, a food-grade antifreeze. The temperature of the water or soil remains relatively constant, even a few feet below the surface. The closed-loop geothermal system can be more efficient than other heating methods, such as gas boilers and furnaces.

The loops can be installed in a trench horizontally or inserted in boreholes that are drilled from to 400 feet deep. Horizontal trenches are best suited for large properties with lots of land whereas vertical boreholes work well for homes and businesses with small spaces. Installing a horizontal ground loop involves digging trenches, which can take a considerable amount of time and effort. In addition the ground has to be compacted so that the loops are able to hold a solid hold on the soil.

On the other hand, a vertical loop system can be constructed much more quickly and easily than a horizontal loop field. The technician makes holes that are 4 inches in diameter spaced 20 feet apart. He then installs the pipe to form an enclosed circuit. The number of holes you need will depend on the building’s size and the energy requirements.

To ensure that your geothermal cooling and heating system operating at peak performance it is crucial to maintain the loop fields. This involves cleaning the loop fields and conducting periodic testing for bacteriological issues.

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 because temperatures in the ground and in the water remain relatively stable, compared to the fluctuating outdoor air temperature. There are four major types of geothermal heating loops, and the one you choose to use depends on the size of your property as well as its layout. The type of loop that is used and the method of installation determine the effectiveness and efficiency of your geothermal system.

Horizontal geothermal heat pump systems make use of a set of pipes buried horizontally in trenches that are about four to six feet deep. The trenches are constructed to accommodate three to four pipe circuits. The pipe circuits are connected into an amanifold that is the central control unit of the geothermal heat pumps. The manifold pumps 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 amount of land to cover them. As technology improved it was discovered that layering a single pipe back and forth at various depths in trenches that were smaller could reduce the amount of space needed and also costs without losing performance. This is the reason for the “slinky” method of installing horizontal geothermal loops.

In cases where there isn’t enough land, a vertical ground loop system can be an ideal alternative. It is also an option for homes situated in urban areas in which the topsoil is scarce and there isn’t any room for horizontal loops. If your property is in an earthquake-prone zone and is not able to support the horizontal loop, a vertical loop system might be the best option.

A geothermal lake or pond heat pump system can be the best option for your home when you have access to an ample amount of water. This type of system works the same as a horizontal or vertical ground loop geothermal heat pump however, the water is used to heat and cooling, instead of the earth. Remember that a geothermal loop system that utilizes a lake or pond cannot function in the event of power outage. Installing a backup generator can provide electricity during this period.

Desuperheater

Geothermal heating is a cost-effective alternative to conventional methods. However, when switching to geothermal homeowners must weigh upfront costs against total energy savings. There are many factors to consider, including the soil composition and the local climate. One of the most important choices is whether or not to bury ground loops, or use an external tank for hot water. The latter option may be less expensive, however it might not offer as much efficiency.

A desuperheater is a device that transfers heat from a geothermal heating system to your hot water tank. It is designed to operate during winter, when the cooling cycle of the system produces excess heat. The desuperheater uses this waste heat to boost the heating performance of your home. It lowers your energy use by using pre-existing resources.

The optimal design of desuperheaters is determined by several physical, geometric, and thermal factors. These include the injection angle, temperature of the water spray, and the nozzle design. These are all crucial factors that affect the performance and operation of the desuperheater.

In the summer, desuperheaters can save up to 80 percent more in a heating dominated climate than the conventional hot water heater. This is because the desuperheater makes use of the energy that is emitted from the home during the cooling process and converts it to useful heat for the hot water generator. Geothermal systems can supply domestic hot water for 3 to 5 months of the year for a fraction of the cost of other energy sources.

The desuperheater also comes in handy in the winter months, when a geothermal heating system is operating at its lowest capacity. The device eliminates the excess heat generated by the cooling system and then adds it to the domestic hot water tank. This allows the domestic hot water tank to make use of this free energy, and increases the heating capacity of the system. The desuperheater may also be used to reduce the time that the geothermal system is in operation in a climate with a high degree of heating.
