PROBLEM TO BE SOLVED: To prevent thermal loss by preventing the self-flash of the rare absorption liquid flowing into a low heat source regenerator even when the heat source is not supplied to the low heat source regenerator. SOLUTION: A second rare absorption liquid pump P2 is mounted on the side of a low heat source regenerator 9 of a rare absorption liquid pipe 15 connecting an absorber 2 and the low heat source regenerator 9 through a first rare absorption liquid pump P1 and the like; and the upstream side of the second rare absorption liquid pump P2 and the upstream side of an intermediate absorption liquid pump P3 of an intermediate absorption liquid pipe 16 connecting the low heat source regenerator 9 and a high-temperature regenerator 5 through the intermediate absorption liquid pump P3 are communicated with each other through a bypass pipe 17. In the low heat source regenerator 9 with an intermediate absorption liquid pipe 16 connected to its bottom, a heat transfer pipe 9B is mounted under a sprayer 9A. The start/stop of the second rare absorption liquid pump P2 is controlled on the basis of a temperature of the heat source flowing into the low heat source regenerator 9 or discharged from the low heat source regenerator 9, and a temperature of the brine flowing into an evaporator 1 or discharged from the evaporator 1, and a rotating speed of the second rare absorption liquid pump P2 is controlled on the basis of the temperature of the brine.
