How a Geothermal System WorksCooling Mode

A geothermal system circulates a refrigerant vapour into the earth to absorb the heat in the naturally cooler, and stable, sub surface temperatures. With excess heat removed, the cooled refrigerant condenses into a liquid. This liquid expands through an expansion device, lowers the pressure, and causes the temperature to reduce even further.

Refrigerant is then circulated through the fan coil unit cooling your home, building or office, and absorbing the excessive heat from the interior air. This causes the refrigerant to expand back into a vapour. The cycle repeats.

Due to these much lower condensing temperatures, the heat pump achieves both an uplift in capacity as well as a reduction in energy consumption. This combination delivers excellent system efficiencies.

System Control

Our geothermal system can be controlled either by wall mounted thermostat or BMS interface.

Geothermal Heat Pump

Our geothermal heat pumps are Australian designed and manufactured. Small, compact and quiet, our geothermal heat pumps offer flexibility in design and location.

Geothermal Ground Loops

All loops are manufactured to ISO:9001 standards, and are delivered to site preassembled and to strict quality controls. Each loop is installed to a specified depth and encased in a special geothermal grout. Where multiple loops are installed, an 8m separation is required. Total number of loops is determined by the buildings air conditioning load.

Horizontal Lines

Where multiple loops are installed, connection to heat pumps is by way of refrigerant lines installed horizontally. Depth of lines is subject to site requirements and in ground service co-ordination.

Heating Mode

When operating in heating mode, cold refrigerant is circulated within the geothermal loop. This absorbs the heat naturally supplied by the earth.

This heated refrigerant vapour is compressed, and circulated through the fan coil unit, heating the space.

This removes the heat from the refrigerant, cooling it again.

The cycle repeats.

Geothermal systems rely on the constant temperatures of the ground that are typically equal to average ambient temperatures.

Conventional cooling and heating systems rely on air temperatures for heat transfer that vary on a daily basis whereas ground temperatures are a constant. Constant heat transfer provides both greater efficiencies and reliability in performance.

Internal Works

All internal works are conventional. No alternate design or installation methodology is required to accommodate a geothermal system. Our geothermal system uses Australian manufactured fan coil units.

The Geothermal Advantage

Renewable Energy Solution

Recognised internationally as a renewable energy solution, a geothermal system will contribute significantly and cost effectively in achieving sustainability objectives on any project.

Reduced Plant

Geothermal heat pumps are significantly smaller than conventional air conditioning units and do not require ventilation. This allows for flexibility in plant location.

Acoustic

The geothermal heat pumps operate at 51db (at 1m), significantly less than conventional outdoor air conditioning units, offering considerable value. Heat pumps do not require acoustic treatment as a conventional plant would.

Design

Geothermal heat pumps are significantly smaller than conventional air conditioning systems and offer greater flexibility in design locations.Safety screening and associated build works required with conventional air conditioning plants are not required.

Energy Efficency

Alinta Energy Geothermal heating and cooling system solutions deliver high levels of energy efficiency. When combined with the passive hot water production, the geothermal system can deliver real and tangible benefits for the life of any facility.

No Requirement for Gas Connection

Geothermal systems are reverse cycle thus, removing need for gas heating.

No Defrost Cycle

As geothermal systems utilise the constant temperatures of the ground; there is no requirement for defrost cycles that are necessary with conventional systems in colder climates. This is a significant benefit in both comfort and efficiency.

Reduced Maintenance

Geothermal systems have no external fans or condenser coils reducing ongoing maintenance requirements.

“The use of geothermal at Fairwater can reduce peak energy demand which translates into reduced household costs.

In an environment of increasing energy costs, we believed that this was a genuine advantage to our customers”

Paolo BevilacquaGeneral Manager, Real Utilities Frasers Property Australia

Fairwater achieved a 6-Star Green Star Communities Rating from the Green Building Council of Australia. All 850 homes will be connected to a geothermal heat pump, reducing household heating and cooling related energy costs.

Geothermal System ComponentsMaintenance-Free Geothermal Loop

The main feature of the geothermal system is the geothermal loop installed underground. Our geothermal system’s condenser loop is permanently buried and is fully encased with a specialised grout and requires no servicing or future maintenance.

Heat Pump

Australian designed and manufactured, the geothermal heat pump is developed for local conditions. Compact and quiet, the geothermalheat pump is easily integrated into any design.

Fan Coil Unit

Your design tasks are simplified by our geothermal system’s use of high-quality off-the-shelf fan coil units manufactured in Australia. The geothermal system requires no changes to conventional duct designs and layouts.

Internal Works

Everything you already know applies because installing a geothermal system is no different from conventional ducted systems. Provide your client with an advanced heating and cooling system without having to change how the building operates.

Controls

Whether it’s a simple wall mounted thermostat or a more complex BMS integration, a geothermal system will provide the right solution for your project needs. Alinta Energy Geothermal have partnered with one of the world’s leading providers of control systems, ensuring we always deliver high level outcomes for our customers.

Geothermal ApplicationsAir Conditioning

Geothermal systems offer more than standard reverse cycle air-conditioning. A geothermal system can be your standard ducted system, but we also offer options that remove the need for cooling towers and boilers. Your designs will benefit with the flexibility of choosing our geothermal configuration based on your project. We work with you to determine the most appropriate and cost effective configuration for your project.

Central Plant

A geothermal system can replace a conventional chiller with our central plant configuration. Modular in design, this system has high levels of flexibility in operation and efficiency. With automated controls integration, a central plant option is an excellent solution for medium to large projects.

Pool Heating

Heating swimming pools is easier and cheaper with a geothermal system. Through using either the primary heating or waste heat from an installed system, a geothermal system is a genuine pool heating solution regardless of project size and scale.

Water Heating & Cooling

A geothermal system can provide water heating and cooling for a variety of purposes. The system can be configured into a central plant primary heating for process or for potable water purposes.

Potable Hot Water

Using waste heat from a geothermal system, potable hot water can be generated at no additional operating cost. A geothermal system can also provide dedicated hot water plant where larger volumes are required.

The geothermal installation at Infinite Care’s new aged care facility in Brisbane consists of 360kW geothermal systems with heat recovery for passive potable hot water production.
