Heat exchanger designed so that in outer boiler cavity a direct transfer of heat takes place via preferably condensing refrigerant vapour in cavity of double pipe coil to throughflowing water in annular cavity of double pipe coil

摘要

The heat exchanger is designed so that in the outer boiler cavity (19.1) a direct transfer of heat takes place via a medium, which is preferably condensing refrigerant vapour in the cavity of the double pipe coil (17), to a throughflowing medium, which is preferably fresh water in the annular cavity of the double pipe coil, and heating of the heat transfer medium in the inner boiler cavity (18.1) via a medium which is preferably condensing refrigerant vapour in the cavity of the single pipe coil (16).
