Geothermal HVAC

Geothermal is a system that provides heating and cooling. The temperature of the earth beneath the surface is fairly constant throughout the year.

Geothermal systems consist of an underground heat pump, loops and a distribution system (such as air ducts). Learn more about the various parts that make up this energy-efficient system:.

Ground Loop

The Ground Loop is essential to the effectiveness and longevity of geothermal heating and cooling system. It is comprised of pipes that are placed in the yard and connect to the heat pump in your home. The piping will be filled with a water-based fluid and circulated to absorb or distribute heat depending on the requirements of your home. The temperature of the ground stays constant four to six feet below the surface, which makes it a natural source of energy for geothermal systems.

When the system is heating, the liquid used to transfer heat absorbs heat from the earth. It then carries that heat to the heat pump inside your home. The fluid is then pushed back to the loop, where it starts the process of circulating. In cooling mode, it utilizes the opposite method to eliminate the heat that is not needed. It returns it to the loop to start a new cycle.

In a closed loop system, the pipe is filled with a water-based solution and placed in the ground. The solution is safe and non-toxic for the environment. It doesn’t pollute the water supply in underground. The system can also make use of a pond or lake as the source of heat transfer fluid, which is even more environmentally friendly.

Based on the space available depending on the space available, open and closed systems may be installed vertically or horizontally. Vertical systems require fewer trenches than a horizontal one and minimizes disturbance to your landscaping. It is used in areas where soil depths are shallow or in areas where existing landscaping must be maintained.

It is important to select a reliable installer regardless of the type of system. It is crucial to have a well-functioning and well-designed system as geothermal systems consume a lot of energy. A properly installed system will ensure the long-term viability of your system and help you save money on electricity in the long-term. It is crucial to flush the system on a regular basis to get rid of any mineral deposits that could reduce the flow and effectiveness of the heat transfer liquid.

Vertical Loop

Geothermal energy is the energy derived from the Earth that is utilized to heat and cool buildings. This energy can be harnessed by underground loops which absorb thermal energy and transfer it into your building. Vertical ground loops are the most common geothermal system. This kind of system is most commonly used in residential and commercial applications. The heat pump in this system captures the heat energy from the ground and then transfers it to your home or office. In the summer it reverses to provide cooling.

The thermal energy transferred from the ground to your building is stored in a series of buried pipes. These pipes are an essential component of any geo-thermal hvac system. The pipes are made of high-density Polyethylene and circulate water and propylene glycol which is food-grade antifreeze. The temperature of soil or water is 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 inserted into an excavation horizontally or in boreholes that are drilled from to 400 feet deep. Horizontal trenches work best for large properties with lots of land, whereas vertical boreholes work well for businesses and homes with little space. The process of installing horizontal ground loops entails digging extensive trenches that can take a considerable amount of time and effort. In addition the ground has to be compacted to ensure that the loops have a firm 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 of 4 inches in diameter spaced 20 feet apart. He then connects the pipe to create an enclosed circuit. The number of holes required will depend on the size of your structure and the energy requirements.

It is essential to maintain the loop fields to keep your geothermal system running at its peak. This involves cleaning the loop fields and conducting periodic tests for bacteriology.

Horizontal Loop

Geothermal heat pumps transfer 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, unlike the fluctuating outdoor temperature. There are four primary kinds of geothermal heating loops and the one you use will depend on your property size and layout. The type of loop and the installation method used determine the effectiveness and efficiency of your geothermal heating system.

Horizontal geothermal heat pumps make use of a set of pipes buried horizontally in trenches that range from 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 geothermal heat pump’s central control unit. The manifold is then able to send chilled and heated water to your home’s cooling and heating ductwork.

Originally the pipes were buried in vertical trenches, which required more land space to surround the pipes. As technology advanced it was realized that layering a longer single pipe back-and-forth in varying depths within shorter trenches decreased the space required and cost, without losing performance. This was the beginning of the “slinky” method of constructing horizontal geothermal loops.

A vertical ground loop system is an excellent alternative to a horizontal geothermal heat pump system in cases where there isn’t enough land available. It is also a good alternative for homes in urban areas, in areas where the topsoil layer is thin and there isn’t much space for horizontal loops. If your property is located in an earthquake-prone zone and cannot support the horizontal loop, the vertical loop could be the best choice.

If you have plenty of water in your home, ponds or lakes can be an excellent alternative for your home. This type of system is similar to a horizontal or vertical ground loop geothermal heating pump, but instead of using the earth for cooling and heating it uses water to heat and cool. It is important to keep in mind that a system that utilizes a pond or lake loop will not function in the event of an electrical power failure. Installing a backup generator will provide power during this time.

Desuperheater

Geothermal heating and cooling is a very efficient alternative to traditional methods. However, when switching to geothermal homeowners must weigh the initial costs with total savings on energy. There are a myriad of factors that come into play including the local climate and soil’s makeup. But one of the biggest choices is whether to plant ground loops or install an external hot water tank. The latter option may be cheaper, but it won’t provide the same efficiency.

A desuperheater can be described as a piece of equipment used to transfer heat from a geothermal source 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 utilizes this heat to improve the heating performance of your home. It also reduces your energy consumption by utilizing pre-existing sources.

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

During the summer months, desuperheaters can save up to 80 percent in a climate that is dominated by heating than a conventional hot water heater. The desuperheater transforms the energy removed from the house during the cooling process into heat for the hot water generator. Geothermal systems 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 is also useful in the winter, when the geothermal heating system is at its lowest capacity. The device eliminates the excess heat produced by the cooling system and adds it to the domestic hot water tank. This enables the domestic hot water tank to utilize this energy for free and also increases the heating capacity of the system. The desuperheater could be used to reduce the amount of time a geothermal system is active in a climate with a high degree of heating.
