The commonly used energy in Iranian greenhouses is provided from gas or diesel fuel. As fossil fuels will be finished in the coming years, the utilization of renewable energies could be quite significant. In this research, the thermal potential of the soil profile was studied in Kouhsar, Alborz province, Iran, for utilizing the shallow geothermal energy in order to supply thermal demands of building like greenhouses. Therefore, the temperature sensors were set at the four depths of 30, 100, 200, and 300 cm as well as at the ground surface. The results showed that the greater the depth, the less fluctuation of the soil temperature as well as the greater the temperature difference of the soil profile against the ambient air temperature. These results suggest that the potential of the earth could be used to warm up or cool down in this location for an agricultural structure like greenhouse. The soil profile temperature behavior was modeled at different depths by two methods as heat transfer and empirical. The empirical model was simpler than the other one. As the possibility of using geothermal energy in this region has not been investigated. This research could be an effective step for using renewable energy for agricultural structures like greenhouses.

“…The experimental data published by Hatraf et al [58] have been obtained through an EAHX installed at the University of Biskra, Algeria (Longitude 5 ° 44'E, Latitude 34 ° 48 'N), a location characterized by a hot and dry summer, typical of the Saharan climate. The experimental facility consists of four horizontal ducts buried at a depth of 3 m; each duct is 60 m long with an inner diameter of 0.11 m. The external air at the inlet of the EAHX was at a temperature of 36 ° C with two different volumetric air flowrates (135 m 3 h -1 and 156 m 3 h -1 ).…”

Highlights Earth-to-Air Heat eXchanger uses geothermal energy for air conditioning systems. A 2D mathematical model of the EAHX is developed to obtain the system performance. A case study office building is analysed for eight worldwide localities. Air temperature variation along the EAHX and EAHX efficiency are calculated. Reduction of thermal capacity of the coils inside air handling unit is evaluated.

“…Also, the seasonal energy efficiency ratio (SEER) for ETAHE was 2 to 3. A study of the parameters influencing the performance of air-ground heat exchangers in arid regions was conducted by Hatraf et al [74], such as the nature of the soil, depth, diameter of the pipe depth and induced airflow.…”

Earth to Air Heat Exchanger ETAHE or Air Ground Heat Exchanger (AGHE) is a renewable technique based on geothermal source used for many centuries in arid and desert regions and considered as a principal element of vernacular and traditional architecture. Arid regions are characterized by a severe winter and summer weather conditions leads to a large thermal discomfort for the big part of the year. Many researchers studied the potentials of this technique to ensure thermal comfort inside buildings for summer and winter seasons. The present study is a review of numerical, experimental, parametric and economic studies of an earth to air heat exchanger with a focus on its application in semi-arid and arid regions. Using an air-to-ground heat exchanger for thermal comfort requires a deep understanding of geothermal deposits and these natural potentials and particularly in desert and arid regions.
