Geothermal energy is one type of renewable source of energy that can be used as shallow geothermal system for the use of cooling and heating of residential and commercial buildings. In this paper, an intense review is carried out on geothermal heating and cooling for air conditioning with a focus on Earth-Air Heat Exchanger (EAHE) and Ground Source Heat Pump (GSHP) systems. The study is carried out to understand the factors which have a significant effect on the performance of the EAHE and GSHP systems. This paper also focuses on the hybrid work of geothermal heating and cooling system with other forms of energy and provides benefits for designing efficient GSHP and EAHE systems. This study indicates that the important parameters for EAHE and GSHP systems are the thermal conductivity of soil, the water content present in the ground will significantly improve the performance of the systems, and further benefits are discussed in this study.
地热能是一种可再生能源，可作为浅层地热系统用于住宅和商业建筑的制冷和供暖。本文对用于空调的地热供暖和制冷进行了深入综述，重点关注地-气热交换器（EAHE）和地源热泵（GSHP）系统。开展这项研究是为了了解对地-气热交换器和地源热泵系统性能有重大影响的因素。本文还关注地热供暖和制冷系统与其他能源形式的混合工作，并为设计高效的地源热泵和地-气热交换器系统提供了益处。这项研究表明，地-气热交换器和地源热泵系统的重要参数是土壤的导热率，地下存在的水分将显著提高系统的性能，本研究还讨论了进一步的益处。
