Geothermal HVAC

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

Geothermal systems consist up of a heatpump underground loops, and the 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 efficiency and long-lasting. 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 according to the requirements of your home. The temperature of the ground is constant between four and six feet below the surface level, which makes it an ideal energy source for geothermal systems.

When the system is in heating mode in the heating mode, the heat transfer fluid absorbs heat from the earth and 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, the system uses the opposite process to eliminate the excess heat and return it to the loop, where it begins a new cycle.

In a closed-loop system the piping will be filled with a solution made of water and buried underground. The solution is safe and not harmful to the environment, and does not pollute the water supply in underground. The system can also utilize lakes or ponds to provide heat transfer fluid, which is even more sustainable.

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

It is essential to choose an experienced installer, regardless of the type of system. Geothermal systems require large amounts of energy to run, and it is crucial to have an efficient and well-designed system in place. A quality installation ensures the longevity of your geothermal system and saves your money on electricity costs in the long term. It is also critical to flush the system regularly to remove any mineral buildup, which could hinder the flow of the heat transfer fluid and hinder the efficiency of the system.

Vertical Loop

Geothermal energy is the energy from the Earth that is utilized to heat and cool buildings. This energy is harnessed by using a series of underground loops that absorb thermal energy and transmit it to your building. Vertical ground loops are the most commonly used geothermal system. This kind of geothermal system is 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 operates in reverse to provide cooling.

The thermal energy that is transferred from the ground to your house is stored in a set of underground pipes. These pipes are a key element of any geo thermal HVAC system. The tubes are made from Polyethylene with high density and circulate water as well as propylene glycol, a food-grade antifreeze. The temperature of the water or soil remains relatively constant at 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 erected in a horizontal trench or put into boreholes drilled to a depth of 100 to 400 feet. Horizontal trenches are typically used for larger homes with a lot of available land and vertical boreholes are ideally suited for businesses or homes that have small spaces. The process of installing horizontal ground loops entails digging extensive trenches that can take a lot of time and effort. Additionally, the ground must be compacted to ensure that the loops have a strong grip on the soil.

A vertical loop system is more straightforward to install than a horizontal field. The technician makes holes of 4 inches in diameter, separated by 20 feet. He then installs the pipe to form a closed circuit. The number of holes needed will depend on your building’s size and energy requirements.

It is vital to maintain the loop fields to keep your geothermal system running at its best. This means cleaning the loop fields and performing periodic tests for bacteriology.

Horizontal Loop

Geothermal heat pumps transfer energy between your home and the ground or a nearby body of water, instead of from the outdoor air. The reason for this is that the temperature of the ground and the water is relatively constant, unlike outdoor air temperatures that fluctuate. There are four major types of geothermal heating loops and the one your system uses depends on the size of your property as well as its layout. The type of loop used and the installation method used determine the efficiency and effectiveness of your geothermal heating system.

Horizontal geothermal heat pumps utilize a series of pipes buried horizontally within trenches that are four to six feet deep. The trenches are constructed to accommodate three to four pipe circuits. The pipe circuits are connected to a manifold, which is the central control unit. The manifold then delivers heated and cooled water to your home’s cooling and heating ductwork.

Initially the pipes were buried in vertical trenches which required a larger area to cover the pipes. As technology improved and technology improved, it was discovered that layering a single longer pipe back and forth at varying depths in shorter trenches could decrease space requirements and costs without the loss of performance. This was the birth of the “slinky” method of constructing horizontal geothermal loops.

In cases where there isn’t enough land available, a vertical loop system is an ideal alternative. It is also a good alternative for homes in urban areas where the topsoil is a bit thin, and there is not much space for horizontal loops. If your property is located in an earthquake-prone region and cannot support an horizontal loop system, a vertical loop system might be the best option.

A geothermal lake or pond heat pump system can be the ideal option for your home when you have access to an abundance of water. This kind of system is similar to a horizontal or a vertical ground loop geothermal heating pump, but instead of using the earth for heating and cooling, the water is used. Keep in mind that a geothermal loop system using lakes or ponds cannot function in the event of a power outage. Installing a backup generator will supply electricity during this time.

Desuperheater

Geothermal cooling and heating is a highly efficient alternative to traditional methods. But when switching to geothermal homeowners must consider balancing upfront costs against the total savings on energy. There are many variables that play into the equation, including the local climate and soil’s makeup. One of the most important choices is whether to put in ground loops or use an external hot water tank. The latter is more affordable, but it might not offer the same level of efficiency.

A desuperheater is an equipment that transfers heat from a geothermal system into your hot water tank at home. It is designed to work in winter, when the cooling process of the system produces excess heat. The desuperheater removes this waste heat and utilizes it to improve the efficiency of your heating system. It reduces your energy usage by using existing resources.

The optimal design of a desuperheater is dependent on a variety of physical, geometric, and thermal variables. These include the spray water temperature, the angle of injection, as well as the design of the nozzle. These are all elements that can affect the performance and efficiency of the desuperheater.

In a climate dominated by heating, a desuperheater will save you as much as 20% more than a traditional water heater in the summer. The desuperheater converts the energy that is removed from the house during cooling into heat for the hot-water generator. The geothermal system can provide hot water to homes for 3 to 5 months of the year for a fraction of the cost of other energy sources.

The desuperheater is also useful in winter, when the geothermal heating system is at its lowest capacity. The device can add the additional heat produced 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 could be used to cut down on the time that a geothermal system is active in a heating dominated climate.
