PROBLEM TO BE SOLVED: To provide a technology for making performance of a lithium-bromide absorption-refrigerator recover, when a spray nozzle is clogged and the performance is degraded. SOLUTION: From the refrigerator, a refrigerant spray pump (not shown) is demounted, which sucks and discharges liquid refrigerant (water) accumulated in the bottom of an evaporator 4 to a spray nozzle 15, and a cleaning liquid circulating tank 17 is temporarily placed. A cleaning liquid circulation pump 19 is connected to the tank 17 to suck and discharge the cleaning liquid of the tank. An inert gas (e.g., nitrogen gas) is injected in a high vacuum space of the refrigerant circulation system to inhibit inflow of air. The cleaning liquid is sent to the nozzle 15 and sprayed, and at the same time, the liquid refrigerant accumulated in the bottom of the evaporator 4 is conducted to the tank 17, and sucked by the pump 19 for circulation.
