To provide an integrated heat exchanger capable of being miniaturized and reducing the cost by integrating a low-temperature regenerator and a condenser in a double-utility absorption refrigerator.
In this double-utility absorption refrigerator utilizing high-temperature refrigerant vapor generated in a high-temperature regenerator for heating the low-temperature regenerator, the integrated heat exchanger 1 composed of the low-temperature regenerator and the condenser is used, elements 2c, 3c are formed by overlapping two plates of which both surfaces are made uneven, to each other, a plurality of elements 2c, 3c are overlapped to constitute a low-temperature regenerator core 2 and a condenser core 3, the low-temperature regenerator core 2 and the condenser core 3 are accommodated in one casing 5 in parallel with each other, and a space excluding an upper space of the casing 5 is partitioned into a low-temperature regenerator side and a condenser side by a partitioning plate 4.
