PURPOSE: To attain a high coefficient of performance without enhancing the pressure of a high-pressure side by using the heat of decomposition generated in a high-temperature AHC cycle as the drive source of an intermediate temperature GAX cycle, and using the heat of absorption generated in the high AHC cycle and the intermediate temperature GAX cycle as the drive source of a low temperature AHE cycle.
CONSTITUTION: The absorption type refrigerant comprises cycle passages X1, X2 and X3 for forming a high-temperature AHE cycle X2, an intermediate- temperature GAX cycle X2 and a low-temperature AHE cycle X3 for circulating refrigerant solution from the high temperature part 1A of a generator 1, refrigerant solution from the intermediate temperature part 2B of the generator 1 and refrigerant solution from the low temperature part 1C of the generator 1 to the high temperature part 1A of the generator 1, the intermediate part 1B of the generator 1 and the low temperature part 1C of the generator 1 via the high temperature part 4A of an absorber 4. The heat of decomposition of the high temperature generated in the cycle X1 is used as the drive source of the cycle X2, and the heat of absorption generated in the cycles X1 and X2 is used as the drive source of the cycle X3.
