Heat from solar pond has been successfully extracted from lower convective zone (LCZ). An attempt to extract the absorbed heat in non-convective zone (NCZ) using external heat exchanger is introduced with aim to enhance the overall efficiency of solar pond. A sets of external heat exchanger system are installed to extract heat at different level in NCZ by withdraw the hot brine and re-injecting it back at the same level. Cold brine from upper convective zone (UCZ) is used to collect the extracted heat from each of heat exchanger. The result shows by extracting heat from NCZ, the thermal efficiency of solar pond could be increased by up to 50% compared to the common heat extraction solely from LCZ and reducing the upward heat lost to surrounding. © Published under licence by IOP Publishing Ltd.
