To provide an absorption type refrigerating device capable of increasing heating capacity of a high-temperature regenerator and simplifying starting motion at low costs.
The plurality of high-temperature regenerators 1w, 1 are disposed, and connected in series with a constitution that absorbing liquid 1aw, 1cw and refrigerant vapor 1bw of the high-temperature regenerator 1w of a former stage are applied to the high-temperature regenerator of a next stage, to increase a heating capacity, and a head H is given between liquid levels of the absorbing liquid law, 1cw of the high-temperature regenerator 1w and liquid levels of the absorbing liquid 1a, 1c of the high-temperature regenerator 1. In a first starting motion, heating of the regenerator of former stage 1w and the regenerator of next stage 1 are simultaneously started, then the heating of the regenerator 1 of next stage is reduced by a prescribed amount when the liquid level of the regenerator 1w of former stage is over a prescribed level ex, the prescribed reduction is released after the continuation of a first prescribed time τx, and the starting is completed when the heating is continued for a second prescribed time τy. In a second starting motion, the heating is continued for the second prescribed time τy, when the liquid level of the high-temperature regenerator 1w of the former stage is lower than the prescribed value after starting, and then the starting is completed.
