2007 Wels energy saving + construction fair
Fair report from the construction and energy saving fair in Wels March 2007
Deep drill for heat of the earth
This 8 tons heavy drilling machine drills holes for the usage of the heat of the earth. In average, 30 litre Diesel per hour consumed and 20m deep drilled.
Heat pump with high COP
Higher COP and less energy usage by electronic injection of the coolant. This together with other measurements gives an unusual high COP.
Airing for buildings
Large airing systems for residential or office buildings with over 90% heat recovery for 800 to 15.000 m³ air exchange per hour.
Preheating for the air before the heat exchanger
The systems for using the heat of the earth are here combined with an airing system. The air from outside is warmed up before the heat exchanger by the heat of the earth.
