Geothermal Air Conditioning – Fan Coil Heating & Air Conditioning

Air as a medium of heat transfer is most commonly used because of its ability to provide comfortable heating and cooling. There is a perception that ducted systems are noisy, draughty and unhealthy. This is because many systems in Australia don’t meet engineering best practice. Geomaster engineers design ducted heating and air conditioning systems that are quiet and comfortable.

The facts are that most residential and commercial geothermal air conditioning systems use conventional ductwork to distribute hot or cold air and to provide humidity control. Some geothermal systems use water-to-water heat pumps with one or more fan-coil units, baseboard radiators, or under-floor circulating pipes. Ducting must be properly sized, constructed, and sealed to maintain system efficiency. Ducts must be well insulated and, whenever possible, located inside of the building’s conditioned space.

Air conditioning engineers broadly divide air conditioning applications into what they call comfort and process. Comfort applications aim to provide a building indoor environment that remains relatively constant despite changes in external weather conditions or in internal heat loads.

Air conditioning makes deep plan buildings feasible. Otherwise they would have to be built narrower or with light wells so that inner spaces receive sufficient outdoor air via natural ventilation. Air conditioning also allows buildings to be taller since wind speed increases significantly with altitude, making natural ventilation impractical for very tall buildings.

Comfort applications for various building types are quite different and may be categorized as:
