Geothermal HVAC

In contrast to traditional HVAC systems that run on natural gas, fuel oil propane or electricity, geothermal provides two-in-one heating and cooling. The temperatures of the earth below the surface are fairly constant throughout the year.

A geothermal system is made up of a heatpump, underground loops, and an distribution system. Find out more about the various components that make up this energy-efficient system:.

Ground Loop

The Ground Loop is the most important element to a geothermal system’s effectiveness and long-lasting. It is made up of pipes that can be drilled, or even truncated in the backyard to connect with your home’s heat pumps. The piping will be filled with a water-based fluid and then circulated to absorb or distribute heat based on the requirements of your home. The ground’s temperature is relatively constant from four to 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 earth’s heat and carries it to the heat pump in your house. The fluid is then moved into the loop which then starts to circulate. In cooling mode, it uses the reverse process to remove the heat that is not needed. It then returns it to the loop to begin 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 pollute the water supply in underground. The system can also use a pond or lake as a source of heat transfer fluid, which is more sustainable.

Open and closed systems can be vertical or horizontal depending on the space you require. Vertical systems require less trenches and cause less disturbance to your landscaping than horizontal systems. It is used in areas in which soil depths are low or in areas where existing landscaping must be preserved.

Regardless of the type of ground loop system, it is crucial to select an experienced installer. It is essential to have a well-functioning and well-designed system, as geothermal systems consume a lot of energy. A properly installed system will ensure the longevity of your geothermal system, and can save you money on electric bills in the long run. It is also essential to have the system flushed frequently to eliminate any mineral buildup, which can hinder the flow of heat transfer fluid and hinder system efficiency.

Vertical Loop

Geothermal energy originates from the Earth and is used to heat or cool buildings. This energy can be harnessed by underground loops which absorb thermal energy and then transfer it into your building. The most popular type of geothermal system is known as vertical ground loop. This type of system is most commonly used in residential and commercial applications. The heat pump in this system absorbs the thermal energy from the ground and transfers it to your home or office. In the summer, it works in reverse to provide cooling.

The pipes that are buried store thermal energy that is transferred from the earth to your house. These pipes are an essential element in any geo thermal HVAC system. The pipes are made of high-density polyethylene and circulate a mixture of propylene glycol and water which is a food grade antifreeze, through the system. The temperature of soil or water stays fairly constant for a few feet beneath the surface. This enables the closed-loop geothermal heat pump to be more efficient than other heating systems, like gas furnaces and boilers.

These loops can either be placed in the horizontal direction of a trench or placed into boreholes that are drilled from 100 to 400 feet deep. Horizontal trenches are usually utilized for larger properties that have a lot of available land and vertical boreholes are best suited for homes or businesses that have small spaces. The installation process for a horizontal ground loop involves digging large trenches that take a lot of time and effort. In addition, the ground must be compacted to ensure that the loops are able to hold a solid grip on the soil.

On the other side vertical loop systems can be constructed much faster and more easily than a horizontal loop field. The technician digging holes that are 4 inches in diameter and approximately 20 feet apart, and installs the piping to form an enclosed loop. The number of holes you need will depend on the dimensions of your building as well as the energy needs.

It is crucial to maintain the loop fields to keep your geothermal system running at its best. 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 water instead of the air outside. This is because ground and water temperatures remain relatively stable, unlike the fluctuating outdoor air temperature. The dimensions and layout of your property will determine the type of loop you use. The type of loop you choose to use and the installation method determine the effectiveness and efficiency of your geothermal system.

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

Originally, these piping system were placed in vertical trenches that required a larger expanse of land to cover them. As technology advanced and technology improved, it was discovered that layering a single longer pipe back and forth different depths in smaller trenches could decrease the amount of space needed and also costs without the loss of performance. This is the reason for the “slinky” method of constructing horizontal geothermal loops.

In cases where there isn’t enough land available, a vertical loop system can be an option. It’s also a great alternative for homes in urban areas in areas where the topsoil layer is thin and there isn’t much space for horizontal loops. A vertical loop system can be a good option when your property is located in an earthquake-prone region and is not able to support the horizontal loops.

If you have a lot of water in your home lakes, ponds or ponds could be a great option for your home. This kind of system is similar to a horizontal or a vertical ground loop geothermal heating system however, instead of using the earth to heat and cool the water is used. It is crucial to note that a geothermal system that uses lake loops or ponds is not functional in the event of a power failure. A backup generator should be installed to provide an electric source during this period.

Desuperheater

Geothermal heating and cooling is a highly efficient alternative to conventional methods. When it comes to switching homeowners must balance the initial costs with the energy savings in the long run. There are many factors to consider, including the soil composition and local climate. But one of the biggest choices is whether to put in ground loops or build an external hot water tank. The latter option may be cheaper, but it may not provide as much efficiency.

A desuperheater can be described as a piece of equipment that transfers heat from a geothermal system into your hot water tank at home. It is designed to operate in winter, when the cooling process of the system generates excess heat. The desuperheater uses this waste heat to boost the heating efficiency of your home. It reduces your energy usage by using resources already in use.

The best design of a desuperheater is dependent on several physical geometric, thermal, and variables. These factors include the injection angle, temperature of the water spray, and the nozzle’s design. These are all crucial factors that affect the desuperheater’s operation and performance.

In the summer, a desuperheater can save up to 80 percent more in a climate with a high degree of heating than a conventional hot water heater. The desuperheater converts the energy taken from the house during the cooling process into heat for the hot water generator. This allows 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 the winter months, when a geothermal heating system is at its lowest capacity. The device eliminates the excess heat produced by the cooling system and then adds it 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 could be used to cut down on the time that geothermal systems are in operation in a heating dominated climate.
