In-ground cooling system componentsThis cooling system will use the cooling effect of the lower ground temperature to reduce the temperature indoors. The In-Ground Cooling System enables you to cool your house or office by drawing fresh cooled air in through a series of pipes burried up to a metre undergroud.  Ideally the air intake should be in a cool, shaded area outside, and the pipes installed in slightly damp ground e.g. where a garden is watered, as the evaporation of any moisture helps the performance of the cooling sytem. The In-Ground cooling sytem has proved very effective in Australian conditions, not only helping you to keep cool, but also ensuring good ventilation throughout summer.
