Geothermal HVAC

Geothermal is a system that can provide cooling and heating. The temperature of the earth beneath the surface is relatively constant throughout the year.

Geothermal systems consist up of a heatpump, underground loops and a distribution system. Find out more about this energy-efficient system’s components:.

Ground Loop

The Ground Loop is crucial to the efficiency and durability of geothermal heating and cooling system. It consists of pipes that are either placed in the backyard and connected to the heat pump in your home. The pipes will be filled with a water-based solution and then circulated to absorb or distribute heat depending on the needs 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 up, the liquid used to transfer heat absorbs heat from the earth. It then transmits that heat to the heat pump inside your home. The fluid is then moved into the loop which is then able to circulate again. In cooling mode, it employs the opposite process to remove the heat that is not needed. It returns it to the loop to start a new cycle.

In closed loop systems, the piping is filled with a water-based solution and buried in the ground. The solution is safe and non-toxic to the environment, and it does not affect the water supply of underground. The system can use lakes, ponds or other body of water as a source for heat transfer fluid. This is even more eco-friendly.

Open and closed systems can be vertical or horizontal, depending on the space you require. Vertical systems require fewer trenches and cause less disturbance to your landscaping than horizontal systems. It is commonly used in areas with shallow soil depths or where existing landscaping needs to be maintained.

It is important to select an experienced installer regardless of the kind of system. Geothermal systems require substantial amounts of energy to operate, and it is crucial to have a well-designed and efficient system in place. A quality installation ensures the longevity of your geothermal system, and saves you money on electric bills in the long term. It is also essential to have the system flushed frequently to eliminate any mineral buildup, which can hinder the flow of the heat transfer fluid and hinder the efficiency of the system.

Vertical Loop

Geothermal energy originates from the Earth and is utilized to cool or heat buildings. The energy is harnessed using a series of underground loops that absorb thermal energy and transfer it to your building. The most popular type of geothermal system is known as a vertical ground loop. This type of geothermal system is typically used in commercial and residential applications. This system makes use of the heat pump to transfer energy from the earth into your home or office. In the summer, it reverses to provide cooling.

The pipes that are buried store the thermal energy that flows from the earth to your building. These pipes are an essential element of any geo thermal HVAC system. The tubes are made of high-density polyethylene and circulate the mixture of propylene glycol and water which is a food grade antifreeze, throughout the system. The temperature of the water or soil stays relatively constant for 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 be placed in a horizontal trench, or placed into boreholes that are made to a depth of 100 to 400 feet. Horizontal trenches are best suited for large estates with lots of land, vertical boreholes are suitable for businesses and homes with limited space. The process of installing horizontal ground loops entails digging large trenches that require considerable time and effort. Additionally the ground needs to be compacted so that the loops have a firm hold on the soil.

On the other the other hand the vertical loop system can be constructed quicker and with less effort than a horizontal loop field. The service technician digs holes that are 4 inches in diameter and about 20 feet apart, and installs the piping to form an enclosed loop. The number of holes you need will depend on the building’s dimensions and energy requirements.

It is vital to maintain the loop fields to keep your geothermal system functioning at its peak. This involves cleaning the loop fields as well as performing periodic testing for bacteriological issues.

Horizontal Loop

Geothermal heat pumps transfer energy between your home and ground or nearby bodies of water, and not from the outdoor air. The reason for this is that the temperatures of the ground and water are relatively constant, unlike outdoor air temperatures, which fluctuate. There are four primary kinds of geothermal heating loops, and which one you use will depend on your property size and layout. The type of loop used and the installation method used determine the efficiency and effectiveness of your geothermal heating system.

Horizontal geothermal systems use a series horizontal pipes buried in trenches between four and six feet in depth. The trenches can hold up to three pipe circuits. The pipe circuits are connected to a manifold which is the central control unit. The manifold is a conduit for heated or chilled water into your home’s heating or cooling ductwork.

Initially, these piping systems were placed in vertical trenches that required a larger expanse of land to surround them. As technology improved it was discovered that laying a single, longer pipe back and forth different depths in smaller trenches could help reduce the space required and cost without sacrificing performance. This was the beginning of the “slinky” method of installing horizontal geothermal loops.

In situations where there isn’t enough land available, a vertical loop system is an ideal alternative. It can also be an option for homes located in urban areas in which the topsoil is scarce and there is little if any space for horizontal loops. A vertical loop system could also be the best solution for properties that are located in an earthquake-prone zone and cannot support an horizontal loop.

If you have plenty of water available, ponds or lakes can be an excellent option for your home. This kind of system is similar to a horizontal or vertical ground loop geothermal heating pump however instead of using the earth to heat and cool, the water is used. It is crucial to note that a geothermal system using a pond or lake loop 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 cooling and heating is a highly efficient alternative to conventional methods. When it comes to switching homeowners must consider balancing the initial costs with the total energy savings. 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 less expensive but may not provide the same level of efficiency.

A desuperheater transfer heat from a geothermal heating system to your home hot water tank. It is designed to operate during winter, when the cooling cycle of the system produces excess heat. The desuperheater removes this waste heat and utilizes it to improve the efficiency of your home’s heating. It can also cut down on your energy usage by using existing resources.

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

In the summer, a desuperheater can save up to 80 percent more in a climate with a high degree of heating than the conventional hot water heater. The desuperheater transforms the energy removed from the home during the cooling process into heat for the hot water generator. Geothermal systems can supply domestic hot water for 3 to 5 months a year, at a fraction of the cost of other energy sources.

The desuperheater also helps in winter when geothermal systems are operating at its smallest capacity. The device eliminates the excess heat produced by the cooling system and transfers it to the domestic hot water tank. This allows the domestic hot water tank to utilize the energy that is free, and also increases the heating capacity of the system. The desuperheater is an effective way to reduce the amount of time that a geothermal heating system is operating when it’s in a location that has a high demand for heating.
