When heating, pass into cryogenic media in the second heat exchanger pipe bundle, make the cryogen water of outer surface evaporate, vaporize, the water vapor of generation is absorbed by the solution that cloth is sprinkled upon the first heat exchanger pipe bundle outer surface, releasing absorbs heat makes the medium in the first tube bank be heated, heat up.
