| 简介 |
It is an objective of the present invention to improve the response performance of absorption refrigeration machine to changes in air-conditioning load by reducing irregularity in solution concentration. A spreader 34 is provided with openings 34a having a constant diameter, and these openings are positioned or aligned in such a manner that the concentration of the openings 34a is rare on one side of the spreader but dense on the other side. The side having the rare concentration of the openings 34a is placed to the lateral wall 1a of a vessel 1 in which a solution outlet 16 is provided. The side having the dense concentration is placed to the other lateral wall 1b of the vessel 1. The spreader 34 is placed at the position where it is slightly away from the solution outlet 16 toward a front wall 1c in a vapor portion of an evaporation-separative region 19, with the bottom plate of the spreader being horizontal. The spreader 34 is provided with supply means 35, which extends parallel to and equidistant from the lateral walls 1a and 1b of the vessel 1. With this supply means, the solution which has absorbed a refrigerant at an absorber is supplied to the longitudinally central portion of the spreader. |
