Abstract
A two-stage absorption refrigerating apparatus includes an integrated drum in which a low-pressure evaporator and a low-pressure absorber are arranged in an upper part and a high-pressure evaporator and a high-pressure absorber are arranged in a lower part. Uncondensed gas resulted in a high-temperature generator and elsewhere successively moves toward a low-pressure side along with a circulation of refrigerant and solution. The uncondensed gas deposited in the high-pressure absorber is extracted by bleeding device, and the uncondensed gas deposited in the low-pressure absorber is extracted by an ejector. The extracted uncondensed gas is stored into a gas storage tank via a gas-liquid separator. A valve is provided on the gas storage tank.
