Advances in standalone and hybrid earth-air heat exchanger (EAHE) systems for buildings: A review
2021, Energy and BuildingsCitation Excerpt :Depending on the climate under consideration, the design of EAHE can be done in terms of seasonal or daily operation, which implies a differentiated set-up [9]. Several applications of this technology can be found, namely in residential buildings [10–17,18], guest houses [19], eco-resort houses [20,21], passive houses [22–24] and near zero energy buildings (NZEB) [25,26], schools [16,27], college [28] and university buildings [29,30], libraries [31], hospitals [32,33], gymnasiums [34], cafeteria buildings [35], office [36–41,42] and commercial buildings [43], welfare institutes [44], as well as in farmhouses [45], livestock houses [46–48], and greenhouses [49–72]. Some studies have also been conducted to assess the feasibility of EAHE for industrial applications, such as: precooling of air for air cooled condensers and air compressors [6]; dry-cooling thermal power plants [73]; super-critical Rankine cycle based power generation units with an EAHE for condenser cooling [74,75]; gas turbine power plants enhanced with EAHE cooling [76,77]; underground diesel generator rooms cooled with EAHE [78], etc.
Effects of buried pipes configuration on the performance of an underground passive cooling system in a desert city of Iran
2021, Journal of Building EngineeringCitation Excerpt :Earth-air-heat exchangers is used to cool the fluid that flows through the buried pipes at the depth of ground where the temperature is lower. The technique of using earth-air-heat exchanger for cooling buildings and greenhouses has been used for decades [5–10]. Ahmed et al. [11] studied the effects of different parameters such as diameter, depth and material of the pipes on the cooling performance of a vertical earth-air-heat exchanger.
Improving the thermal performance of ground air heat exchanger system using sand-bentonite (in dry and wet condition) as backfilling material
2020, Renewable EnergyCitation Excerpt :The temperature of the earth's surface varies with time (diurnal and seasonal) and depth. In some studies, it was observed that diurnal variation of earth surface temperature does not penetrate more than 0.5 m depth and annual variation not more than 4.0 m depth [6–9]. At a certain depth below the ground (3–4 m), the soil temperature remains almost constant throughout the year, and it is equal to the mean annual ambient temperature of that location [10–12].
A review on effect of geometrical, flow and soil properties on the performance of Earth air tunnel heat exchanger
2018, Energy and BuildingsCitation Excerpt :Undisturbed ground temperature (UGT) is usually obtained at a depth of 2–4 m, but it may be more than 4 m at some latitudes. In some studies it was observed that diurnal variation of earth surface temperature not penetrate more than 0.5 m depth and annual variation not more than 4.0 m depth [16,17,126,127]. Popiel et al. [128] measured ground temperature at different depths with bare surface and short grass covered surface and found that the short-period temperature variations were observed up to depth of 1 m only.
