PROBLEM TO BE SOLVED: To improve absorption performance by cooling a dense absorbent from a regenerator by a supercooling device and then supplying the absorbent to an absorber, and causing the dense absorbent from the regenerator to efficiently absorb a refrigerant. SOLUTION: A dense absorbent spray nozzle 23 is provided on the upper part of an absorber body 20, and a diluted absorbent spray nozzle 25 is provided below it. The diluted absorbent spray nozzle 25 and the lower part of the absorber 5 are connected to each other through an absorbent circulating pipeline 28 in which a circulating pump 26 and the supercooling device 27 are interposed. A diluted absorbent supply pipe 29 is connected extending from a portion between the circulating pump 26 of the absorbent circulating pipeline 28 and the supercooling device 27 to the upside of the regenerator 1. A dense absorbent supply pipe 30 is connected to the lower part of the regenerator 1, a dense absorbent supercooling device 31 is interposed in the thick absorbent supply pipe 30, and the dense absorbent supply pipe 30 and the dense absorbent spray nozzle 23 are connected to each other. The dense absorbent is cooled by the dense absorbent supercooling device 31 without being mixed with the diluted absorbent and supplied to the absorber 5. COPYRIGHT: (C)2009,JPO&INPIT
