Geothermal HVAC

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

Geothermal systems are made up of a heatpump, underground loops and the distribution system. Learn more about this efficient system’s components:.

Ground Loop

The Ground Loop is crucial to the durability and efficiency of geothermal cooling and heating system. It is made up of pipes that are either placed in the backyard, and then connected to the heat pump in your home. The piping is filled with a water-based fluid and circulated to absorb or distribute heat based on the needs of your home. The temperature of the ground stays constant four to six feet below the surface, making it an ideal energy source for a geothermal system.

When the system is heating up, the liquid that transfers heat absorbs heat from the earth. It then carries that heat to the heat pump inside your home. The fluid is then returned to the loop, where it starts circulating again. In cooling mode, the system uses the opposite process to eliminate the heat that is left and return it back to the loop, where it begins the next cycle.

In a closed loop system the pipe is filled with a water-based solution, and then is buried in the ground. The solution is safe and non-toxic to the environment, and does not affect the water supply in underground. The system can also use a pond or lake as the source of heat transfer fluid, which is even more eco-friendly.

Both closed and open systems can be horizontal or vertical depending on your space requirements. Vertical systems require less trenches than horizontal systems and minimizes disturbance to your landscaping. It is used in areas in which soil depths are low or in areas where existing landscaping must be maintained.

It is crucial to choose a reliable installer regardless of the type of system. Geothermal systems require a lot of energy to run and it is vital to have an efficient and well-designed system in place. A well-designed installation will ensure the durability of your system and help you save money on electricity over the long term. It is important to flush the system on a regular basis to remove any minerals that could reduce the flow and effectiveness of the heat transfer liquid.

Vertical Loop

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

The thermal energy transferred from the ground to your building is stored in a set of underground pipes. These pipes are a crucial element in any geo thermal HVAC system. The pipes are made from high-density polyethylene. They circulate an emulsion of propylene glycol and water which is a food-grade antifreeze, throughout the system. The temperature of the soil or water stays relatively constant for only a few feet beneath 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 an excavation horizontally or in boreholes drilled from 100 to 400 feet deep. Horizontal trenches are typically utilized for larger properties that have a lot of available land and vertical boreholes are best suited for businesses or homes that have small spaces. Installing a horizontal ground loop involves digging trenches, which can require a lot of time and effort. In addition the ground has to be compacted to ensure the loops have a strong grip on the soil.

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

To ensure that your geothermal cooling and heating system operating at peak performance, it is important to properly maintain the loop fields. This includes cleaning up debris and conducting regular tests for bacteriological issues.

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

Horizontal geothermal heat pump systems utilize a series of pipes buried horizontally in trenches that are about four to six feet deep. 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 is then able to send hot and cool water to your home’s heating and cooling ductwork.

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

In situations where there isn’t enough land, a vertical ground loop system can be a good alternative. It can also be an option for homes in urban areas in which the topsoil is scarce and there is little if any room for horizontal loops. If your home is in an earthquake-prone region and is not able to support an horizontal loop system, the vertical loop may be the best option.

If you have lots of water, ponds or lakes can be a great alternative for your home. This type of system works exactly like a horizontal or vertical ground loop geothermal heat pumps, however, the water is used for heating and cooling instead of the earth. Keep in mind that a geothermal loop system that utilizes a lake or pond is not functional in the event of power failure. Installing a backup generator will provide power during this time.

Desuperheater

Geothermal cooling and heating is a highly efficient alternative to traditional methods. When it comes to making the switch, homeowners have to balance upfront costs with total energy savings. There are a variety of aspects to consider including the local climate and soil’s composition. But one of the biggest choices is whether to put in ground loops or install an external hot water tank. The latter is cheaper, but it may not provide as much efficiency.

A desuperheater transfer heat from geothermal heating systems to your hot water tank. It is designed to operate during winter, when the cooling cycle of the system generates excessive heat. The desuperheater eliminates this waste heat and uses it to boost the efficiency of your heating system. It also reduces the energy use by utilizing existing resources.

The optimum design for a desuperheater depends on several physical, geometric, and thermal variables. These include the spray temperature and the angle of the injection, as well as the design of the nozzle. These are all factors that can influence the performance and operation of the desuperheater.

In a climate dominated by heating, a desuperheater can save you as much as 80% more than a conventional water heater during the summer. The desuperheater transforms the energy removed from the house during cooling into heat for the hot-water generator. This enables the geothermal system to produce domestic hot water for 3 to 5 months of the year at less than the cost of other energy sources.

The desuperheater also comes in handy in the winter, when the geothermal heating system is 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 hot water tank to utilize this free energy and maximizes the system’s heating capacity. The desuperheater is an excellent way to cut down on the amount of time that geothermal heating systems are operating when it’s in a place that has a high demand for heating.
