<p>A falling-film evaporation-cooling absorption refrigeration unit comprises a generator (1), an evaporator (3), an absorber (4), a condenser (5), a throttling device and several cooling-water falling-film sprinkling devices (81). The outer walls or the inner walls of a plurality of heat exchanging tubes or plates (51) of the condenser (5) and the absorber (4) are in contact with the air. At least one cooling-water falling-film sprinkling device (81) is arranged on the upper portion of or above the heat exchanging tubes or plates (51) of the condenser (5) and the absorber (4), so that the cooling-water is sprinkled on the wall contacting the air of the heat exchanging tubes or plates (51) to form a liquid film (100). The liquid film (100) flows down the wall by virtue of the gravity and carries out evaporation-cooling through the convection of the air.</p> |
