WebMar 1, 2024 · Earth-to-air heat exchangers (EAHE) use ground as a heat sink/source and consist of a single or multiple pipes buried in the ground, through which ambient or indoor air is circulated and heat is transferred from the air to the soil during the summer (cooling mode) or from the soil to the air during the winter (heating mode). WebJul 11, 2015 · where k is the thermal conductivity, ρ is the density, and ς is the specific heat of the soil. The amount of heat exchanged between the air and the surrounding soil depends upon various parameters, e. g., surface area of the pipes, length of the pipes, water contents of the inlet air and dampness of the earth, temperature of the earth, air …
Classification of earth−air tube heat exchanger.
WebEarth tube heat exchanger is an underground heat exchanger that can capture heat from and dissipate heat to the ground. They use the earth near constant subterranean temperature (undisturbed temperature) to warm or cool air or other fluids for residential, agricultural or industrial uses. WebMay 1, 2003 · Earth-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. fishtail maternity dress
