<p>The heat exchange circuit is between two gas flows in opposition. It includes heat absorbing and transferring parts, each of a number of heat exchange circuits, in series, and near each other. The first gas flow sweeps the evaporators of these circuits in succession. The second gas flow sweeps the condensers of the various circuits. Circulation of cooling transfer fluid is done between evaporators and condensers independently by liquid and vapour pipework. These form one or more heat pump circuits, their evaporators downstream and near the other evaporators and their condensers similarly placed.</p> |
