Geothermal HVAC

Contrary to traditional HVAC systems that run on fuel oil, natural gas propane or electricity geothermal offers two-in-one cooling and heating. The temperature of the earth beneath the surface is fairly constant throughout the year.

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

Ground Loop

The Ground Loop is essential to the efficiency and durability of a geothermal heating and cooling system. It consists of pipes that are trenched or drilled in the backyard and connected to the heat pump in your home. The piping is then filled with a water-based solution that circulates to absorb or disperse heat according to the needs 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 a geothermal system.

When the system is in heating mode, the heat transfer fluid absorbs Earth’s heat and carries it to the heat pump inside your house. The fluid is then pushed back into the loop where it begins circulating again. In cooling mode, the system utilizes the reverse process to remove the heat that is left and return it to the loop, where it starts the next cycle.

In closed loop systems, the pipe is filled with a water-based solution and is buried in the ground. The solution is safe and not harmful to the environment and does not affect the water supply in underground. The system can utilize a pond, lake or other body of water as a source of heat transfer fluid. This is even more environmentally friendly.

Depending on the available space depending on the space available, open and closed systems may be installed horizontally or vertically. 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 where existing landscaping needs to be preserved.

Whatever the kind of ground loop system, it is crucial to select an experienced installer. It is crucial to have a reliable and well-designed system as geothermal systems consume a lot of energy. A quality installation will ensure the long-term viability of your system and help you save energy costs in the long run. It is also crucial to have the system flushed frequently to eliminate any mineral buildup. This can reduce the flow of the heat transfer fluid and hinder system efficiency.

Vertical Loop

Geothermal energy is derived from the Earth and is used to heat or cool buildings. It is harnessed using a series of underground loops that absorb thermal energy and then transfer it to your building. Vertical ground loops are the most popular geothermal system. This kind of system is used most often in commercial and residential settings. The heat pump in this system takes the thermal energy from the ground and then transfers it to your office or home. In the summer it reverses to provide cooling.

The thermal energy transferred from the ground to your building is stored in a set of underground pipes. These pipes are an essential part of any geo-thermal hvac system. The pipes are made of Polyethylene with high density and circulate water and propylene glycol, a food-grade antifreeze. The temperature of the soil or water remains relatively constant, even only a few feet beneath the surface. This allows the closed-loop geothermal heat pump to be more efficient than other heating systems like gas furnaces and boilers.

These loops can be installed in a horizontal trench, or placed into boreholes that are drilled to the depth of 100- 400 feet. Horizontal trenches work best for large homes with lots of land vertical boreholes are suitable for businesses and homes with little space. The process of installing horizontal ground loops involves digging extensive trenches that can take a considerable amount of time and effort. The ground must also be compacted in order to ensure that the loops are firmly fixed to the soil.

A vertical loop system is more straightforward to install than a horizontal field. The technician makes holes of 4 inches in diameter, spaced about 20 feet apart. He then installs the pipe to form an enclosed circuit. The number of holes needed will depend on the dimensions of your building as well as 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 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 because ground and water temperatures remain relatively stable, unlike the fluctuating outdoor temperature. There are four main types of geothermal heating loops and which one your system uses depends on your property size and layout. The type of loop that is used and the installation method determine the effectiveness and efficiency of your geothermal system.

Horizontal geothermal systems employ series of horizontal pipes, which are that are buried in trenches ranging from four and six feet in depth. The trenches are constructed to accommodate two to three pipe circuits. The pipe circuits are connected into the manifold, which is the central control unit for geothermal heat pumps. The manifold sends heated or chilled water into your home’s heating or cooling ductwork.

In the beginning, these piping systems were placed in vertical trenches that required a larger area of land to encase them. As technology improved it was discovered that laying a single, longer pipe back and forth different depths in smaller trenches could reduce the amount of space needed and also costs without the loss of performance. This was the birth of the “slinky” method of installing horizontal geothermal loops.

In cases where there isn’t enough space, a vertical ground loop system can be a good alternative. It is also an option for homes situated in urban settings, in which the topsoil is scarce and there is little if any space for horizontal loops. Vertical loops can also be the best solution for properties that are located in an earthquake-prone area and cannot support an horizontal loop.

A pond or lake geothermal heat pump system can be the ideal option for your home in the event that you have access plenty of water. This type of system works the same as a horizontal or vertical ground loop geothermal heat pump, but the water is used for heating and cooling, not the earth. It is crucial to note that a geothermal system using lake loops or ponds will not work in the event of an electrical power failure. A backup generator needs to be installed to provide a source of electricity during this time.

Desuperheater

Geothermal heating and cooling is a very efficient alternative to conventional methods. When it comes to switching homeowners must balance the initial costs with the total savings on energy. There are a variety of variables that play into the equation, including the local climate and soil’s makeup. One of the most important choices is whether or not to bury ground loops, or use an external tank to store hot water. The latter is less expensive, but may not provide the same level of efficiency.

A desuperheater is a piece of equipment that transfers heat from a geothermal system into your hot water tank at home. It is designed to operate in the winter when the system’s cooling cycle produces heat that is not needed. The desuperheater takes this wasted heat and uses it to boost the efficiency of your heating system. It helps reduce your energy consumption by using pre-existing resources.

The ideal design for a desuperheater depends on several physical, geometric, and thermal variables. These include the temperature of the spray water, the angle of injection, as well as the design of the nozzle. These are all aspects that affect the performance and operation of the desuperheater.

In a climate dominated by heating, a desuperheater could save you as much as 80% more than a traditional water heater in the summer. This is due to the fact that the desuperheater utilizes the energy emitted by the home during the cooling process and converts it to useful heat for the hot water generator. This allows the geothermal system to create domestic hot water for three months of the year at less than the cost of other energy sources.

The desuperheater can also help during winter, when the geothermal system is operating at its smallest 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 the energy that is free and boosts the system’s heating capacity. Desuperheaters are also an excellent way to cut down on the amount of time that a geothermal heating system is in use when it’s in a location with a high heating demand.
