<p>A system including active heat balance device and fluid transmission pipelines provided inside a solid, liquid, or gaseous thermo carrier with comparatively reliable thermo reservation capacity in the nature to reclaim heat from the fluid flowing in opposite direction by releasing heat to the fluid of relatively lower temperature flowing through the pipelines, or to absorb the heat to cool the fluid of relatively higher temperature flowing through the pipelines in the opposite direction. <IMAGE></p> |
