Experimental study of a stand-alone earth to air heat exchanger for heating and cooling in arid regions

Öz:

Earth to air heat exchanger EAHE is a renewable technique based on a geothermal source.Arid regions are characterised by hard winter and summer weather conditions, which lead to alarge thermal discomfort for the big part of the year. In this paper, we study by experiments theperformance of stand-alone earth-to-air heat exchanger without external devices (fans, etc.),but only with the local climatic conditions of the region of Bechar (located in the Southwest ofAlgeria). The EAHE contains a PVC pipe with 66 meters of length and 110 mm of diameter,and it is buried at a depth of 1.5 m in an agriculture zone, where the annual undisturbed subsoil at 1.5 m is 28°C. The stand-alone EAHE has the capacity to raise the air temperature by10°C in the heating regime and reduce it by 11.9°C in the cooling regime. Furthermore, therelative humidity is raised by19% in the humidification regime and reduced by 27% in thedehumidification regime. The daily working regime was: 62.5% of heating (from 00h to 08hand from 18h to 23h) and 37.5% of cooling (from 09h to 17h) for the thermal regime, 62.5% ofdehumidification (from 00h to 09h and from 18h to 23h) and 37.5% of humidification (from10h to 17h) for the hygrometric regime. The stand-alone EAHE technique presents a greatpotential for the pre-heating, pre-cooling, and natural ventilation of dwellings and buildingsin arid regions.
