WebEarth-air heat exchangers, also called ground tube heat exchangers, are an interesting technique to reduce energy consumption in a building. They can cool or heat the ventilation air, using cold or heat accumulated in the soil. Several papers have been published in which a design method is described. Most of them are based on a discretisation ... WebGround-air heat exchangers offer an innovative method of heating and cooling a building. Ventilation air is simply drawn through underground pipes at approx 1.5m, where the soil temperature is a constant 8-12°C. The soil temperature will pre-cool the air in the summer and pre-heat the air in winter.
WebMar 1, 2024 · Vertical earth-air heat exchanger. A thermal response test (TRT) on the boreholes is essential to understand the thermal properties. A quantified heat load is usually applied into the holes for the thermal response test in which the changes in resulting temperatures are evaluated for the circulating fluid.
