Geothermal Cooling

A geothermal heating and cooling system works on a simple premise: The earth below is at a constant temperature all year round. The earth's temperature changes in response to weather changes, but there is less change at greater depths.

Heat can be taken from within a building and transferred into the ground, cooling the building.

Loops of piping are buried in the ground, either vertically or horizontally and are connected to a circulating pump. The pump circulates a mixture of water and biodegradable antifreeze through the buried pipe loops, and the liquid mixture transports the heat absorbed in the building into the ground and deposits it there as it flows through the loop.

How about lower energy bills?

Depositing heat into the ground is free, and the only energy needed is for moving that heat between the building and the ground. In the ground the heat is transported away, thus using the ground as heat sink is naturally renewable and friendly to the environment.

In large commercial buildings, such as schools and office buildings, the use of geothermal systems means extraordinary savings.

The life-cycle cost of the cooling system is an important economic consideration. Schools, for example, must plan for long-term efficiency to maximize their resources. Geothermal systems have been shown to have competitive initial investment costs, lower operating and maintenance costs, as well as the lowest life-cycle costs compared to other systems. These savings make geothermal cooling ideal for schools of all sizes and locations.

Geothermal components can be added to existing cooling equipment for those wishing to have a dual-fuel system.

A geothermal cooling system is very efficient in combination with Thermo-active building components (TABS)!

More benefits:

• The key economic advantage of a geothermal cooling system is its energy efficiency.
• Straightforward use of a renewable energy source
• Reduction in the energy requirement
• Minimisation of CO2-emissions
• Cost reduction through the use of natural resources
• Design flexibility: Geothermal systems can be easily and inexpensively subdivided or expanded to fit building remodeling or additions.
• Safety: No dangers of gas leaks or carbon monoxide poisoning.
• Lower operating and maintenance costs.
• A geothermal system can cut utility bills significantly compared to conventional cooling systems.

Soil and rock

No single factor is more important to the successful operation of a ground-coupled cooling system than the efficiency of the heat transfer between the ground loop and the surrounding soil. Soil properties and the thermal performance of rocks vary widely. These variations indicate the importance of an accurate estimate before any geothermal loop design can be finalized. A detailed layer-by-layer description of the soil, along with any rock content, density, soil types and available water capacity, is needed.

Since geothermal systems are constructed of components from the radiant heating and air conditioning and the plumbing industries, components are widely available, but engineers experienced in geothermal systems design are not. GPI engineers have many years of experience in installing these systems.
