“…The reduction of greenhouse gas emissions is a result of energy-saving implementation [23][24][25]. GHE for thermal comfort can reduce energy consumption [26]. Ground temperature has been investigated in the past few decades [19,27], and has been used for passive space cooling in many countries [26,28,29].…”

“…Other design parameters of the GHE are shown in Table 1. The thermal and energy performances of a GHE system are influenced by several factors such as pipe specification, pipe material, circulating fan, soil thermal properties and moisture content [26,29]. Previously, [61] reported that the most costeffective combination of pipes for cooling capacity in the Jodhpur (India) climate was 1920 kWh/m 2 with 5 cm radius, 12.5 m length, 2400 m 3 /h of volume flowrate and 16 pipes.…”

The ground heat exchanger (GHE) is one of the energy sources that has been identified since the 1970s which is able to produce sustainable energy for cooling which is in passive side. GHEs are widely implemented around the world, especially in European countries and a few Asian countries. In Malaysia, application of GHE is still considered as a new passive cooling approach in building energy reduction. Therefore, this paper reviews several important ways of implementing GHE in order to supply passive cooling for any application. The review covers general implementation of the GHE for thermal comfort and agricultural greenhouse cooling. The ground temperature variation used in different researches is also reviewed in this paper as an important part of identifying potential GHE implementations. Design and performance aspects of the GHE are also reviewed. Finally, this paper summarizes the potential and benefit of GHE implementation in the Malaysian climate for cooling applications to reduce the energy used in buildings and greenhouse gas emission.

“…Clara Peretti et al [16] and Bisnoyia et al [17] gave an extensive literature review covering design, characteristics of EAHE, modelling adopted by several researchers etc. When the earth air heat exchanger was integrated by solar chimney which utilizes both the geothermal energy as well as the solar energy, the energy savings were greater compared to uncoupled system [18].…”

Abstract:In the present work the ground temperature has been validated for climatic condition of Sriperumbudur near Chennai, India to evaluate thermal conductivity and diffusivity of the soil. For the evaluated thermal conductivity of the soil, an EAHE has been designed for a given dimension of room with optimized values of number of air changes, length of pipe, radius of pipe and depth at which heat exchanger to be installed below the surface of the earth. It has been observed that there is a decrease of 5 -6 0 C in the outlet air temperature in summer for a number of 5 air changes with 0.10 m and 21 m optimized diameter and length of pipe respectively.
