Abstract
A rotary absorption heat pump assembly. The assembly comprises a generator (2), condenser (3), evaporator (4), absorbent cooler (5), and absorber (1), all operatively associated to function as components of an absorption-type heat pump of high efficiency and superior operating characteristics. The heat pump is characterized by the presence of a tapered cylindrical absorber (1) which receives and processes, in the form of a very thin peripheral film ("d"), a predetermined amount of absorbent solution. The absorber (1) is arranged in abutting end-to-end relationship to the generator (2), with which it communicates. The condenser (3) and evaporator (4) are arranged end-to-end outside of the absorber (1) and absorbent cooler (5), concentrically therewith and radially spaced therefrom.
Claims17
A rotary absorption heat pump assembly comprising a generator (2), condenser (3), evaporator (4), absorbent cooler (5), and absorber (1) having infeed and outfeed ends, and means operatively associating the same to function as components of an absorption type heat pump, and
- mounting means for mounting the heat pump components for rotation as a unit,
- the absorber (1) comprising a hollow frustum of a right circular cone, outwardly tapering in the downstream direction and adapted to receive and process an absorbent solution in the form of a very thin film ("d") of substantially uniform thickness,
- the absorber (1), absorbent cooler (5), and generator (2) being arranged centrally end-to-end and the condenser (3) and evaporator (4) being arranged end-to-end peripherally outside of the absorber and absorbent cooler, substantially concentric therewith.
The heat pump assembly of claim wherein the absorber (1) and generator (2) are arranged in end-to-end abutting relationship and wherein the infeed end of the absorber is closed with a first isolation/insulation barrier and its outfeed end with a second isolation/insulation barrier,
- there being provided in the first isolation/insulation barrier a plurality of peripheral openings (33) in juxtaposition to the interior wall (7) of the absorber for feeding absorbent solution to said interior wall in filmforming relation,
- and wherein a downstream second isolation/insulation barrier is provided with a plurality of peripheral openings (54) arranged to deliver absorbent solution in the form of a thin film to the interior peripheral surface of the generator (2).
