The thermal characteristics and performance of a ground heat exchanger for tropical climates

This paper presents the thermal characteristics and performance of ground heat exchanger (GHE) based on the mathematical model for tropical climate conditions. The case study is undertaken with the depth of ground, z of 2 m, air inlet temperature of 35 °C, air mass flow rate of 0.02–0.2 kg/s and dif...
