The present invention relates to a triple-effect absorption chilling apparatus adopting a structure of an anti-parallel cycle in which an absorber and a first regenerator are connected in series, a second regenerator and a third regenerator are connected in parallel with the first regenerator, and the solution through the second regenerator and the third regenerator is returned to the absorber. Therefore, according to the present invention, it is possible to improve efficiency by acquiring a higher coefficient of performance than conventional absorption refrigerators, and to reduce energy consumption.
