Geothermal HVAC

Contrary to traditional HVAC systems that operate on natural gas, fuel oil propane or electricity geothermal can provide two-in-one heating and cooling. The temperatures of the earth below the surface remain relatively consistent year-round.

A geothermal system is comprised of a heat pump, underground loops and a distribution network (such as air ducts). Learn more about this efficient system’s components:.

Ground Loop

The Ground Loop is vital to the durability and efficiency of geothermal heating and cooling system. It is made up of pipes that can be drilled, or even truncated in the yard to connect to your home’s heat pumps. The pipes are then filled with a water-based solution 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, which makes it an ideal energy source for geothermal systems.

When the system is heating, the heat transfer liquid absorbs heat from the earth. It then transmits that heat to the heating pump in your home. The fluid is then returned to the loop, where it starts the process of circulating. In cooling mode, the system utilizes the reverse process to remove the heat that is left and return it back to the loop, where it starts the next cycle.

In a closed-loop system the piping is filled with a solution based on water and then buried beneath. The solution is safe and not harmful to the environment, and does not pollute the water supply in underground. The system can utilize a pond, lake or other body of water as a source for heat transfer fluid. This is even more eco-friendly.

Based on the space available Open and closed systems can be installed vertically or horizontally. Vertical systems require fewer trenches than a horizontal system and is less disruptive to your landscaping. It is used in areas where soil depths are shallow or when existing landscaping needs to be maintained.

It is important to select a reliable installer regardless of the type of system. It is essential to have a well-functioning and well-designed system, since geothermal systems use a lot of energy. A well-designed installation will ensure the long-term viability of your system, and will help you save energy costs in the long-term. It is also essential to have the system flushed frequently to eliminate any mineral buildup that can hinder the flow of the heat transfer fluid and hinder the efficiency of the system.

Vertical Loop

Geothermal energy is the energy that comes from the Earth that is used to heat and cool buildings. It is a source of energy that can be harnessed using underground loops that absorb heat and then transfer it to your building. Vertical ground loops are the most popular geothermal system. This kind of system is typically employed in commercial and residential applications. This system uses an energy pump to transfer thermal energy from the earth to your office or home. In summer, it reverses to provide cooling.

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

These loops can either be installed in the horizontal direction of a trench or placed into boreholes that are drilled from 100 to 400 feet deep. Horizontal trenches are best suited for large properties with lots of land, while vertical boreholes are ideal for homes and businesses with small spaces. Installing a horizontal ground loop involves digging trenches, which could take a lot of time and effort. Additionally the ground needs to be compacted so that the loops are able to hold a solid grip on the soil.

On the other side the vertical loop system can be installed quicker and with less effort than a horizontal loop field. The technician digs holes that are 4 inches in diameter spaced 20 feet apart. Then, he installs the pipe to create a closed circuit. The number of holes required will depend on your building’s size and the energy requirements.

To ensure that your geothermal heating and cooling system operating at peak performance, it is important to properly maintain the loop fields. This means 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, rather than being able to draw energy from the air outside. The reason is that the temperature of the ground and water is generally constant, in contrast to outdoor air temperatures which fluctuate. 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 method of installation used determine the efficiency and effectiveness of your geothermal heating system.

Horizontal geothermal systems use a series of horizontal pipes, which are buried in trenches between four and six feet deep. The trenches can house up 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 heating and cooling ductwork.

Originally, these piping system were placed in vertical trenches that required a larger amount of land to cover them. As technology improved, it was found that layering a single pipe back and forth varying depths in shorter trenches could help reduce the amount of space needed and also costs without the loss of performance. This led to the development of the “slinky method” of installing horizontal geothermal circuits.

A vertical ground loop system can be a great alternative to a horizontal geothermal heating system in cases where there isn’t enough land area available. It can also be an option for homes situated in urban areas in which the topsoil is scarce and there is little if any space for horizontal loops. Vertical loops can also be the best solution if your property is in an earthquake-prone area and is not able to support an horizontal loop.

If you have lots of water available lakes or ponds can be the ideal option for your home. This kind of system operates exactly like a vertical or horizontal ground loop geothermal heat pump, except the water is used for heating and cooling, not the earth. Keep in mind that a geothermal loop system using a lake or pond is not functional in the event of power outage. A backup generator must be installed to provide an electric source during this period.

Desuperheater

Geothermal cooling and heating is a highly efficient alternative to traditional methods. When it comes to making the switch homeowners must consider balancing upfront costs and total savings on energy. There are a myriad of factors that come into play, including the local climate and soil makeup. One of the most important decisions is whether or not to bury ground loops, or use an external tank to store hot water. The latter option is more affordable, but it may not offer the same level of efficiency.

A desuperheater is a piece of equipment that transfers heat from a geothermal system to your hot water tank in your home. It is designed to operate in winter when the cooling process of the system generates excessive heat. The desuperheater eliminates this waste heat and uses it to increase the efficiency of your home’s heating. It reduces your energy usage by using pre-existing resources.

The ideal design for a desuperheater is determined by a variety of physical, geometric, and thermal factors. These factors include the spray temperature, the angle of injection, and the shape of the nozzle. These are all elements that influence the performance and operation of the desuperheater.

In a climate that is dominated by heating, a desuperheater could save you up to 80% more than a traditional water heater in the summer. This is because the desuperheater makes use of the energy removed from the house during the cooling process and converts it to useful heat for the hot water generator. The geothermal system can provide domestic hot water for 3 to 5 months of the year for a fraction of the cost of alternative energy sources.

The desuperheater also helps in the winter when geothermal systems are running at its lowest capacity. The device is able to add the extra heat generated by the cooling system to the domestic hot water tank. This allows the domestic hot water tank to use this free energy, and also increases the heating capacity of the system. The desuperheater is an excellent way to cut down on the time that a geothermal heating system is operating when it’s in a place that has a high demand for heating.
