Page 3: System Description
System description Principle of BWB-SS-DC heat pump BWB-SS-DC series heat pump can exploit the energy contained in natural heat sources. Or, to put it differently, the heat pump 'collects' heat energy from the heat source. The heat from the heat source (rock, soil, lake) is taken up via a closed collector system in which a mixture of water and antifreeze circulates;... -
