The Effect of Flowrate and Effectiveness on Theoretical Design and Thermal Characteristic of a GHE

Ground heat exchanger is an exciting technique to reduce energy consumption in building especially in hot climate countries. Implementation of GHE for commercial unit in Malaysia is almost none in record. Thus, performance study of the GHE in Malaysia is crucial to be conducted either experimentally...
