摘要： PURPOSE:To improve the efficiency of the whole of a waste heat utilizing system, in which a hot-water heating absorption refrigerating machine and a heat exchanger for supplying hot-water are interposed in the waste heat line of a co-generation system in series. CONSTITUTION:Upon controlling the waste heat line L1 of a system, in which a hot-water heating absorption refrigerating machine 2 and a heat exchanger 3 for supplying hot-water are interposed in the wasteheat line L1 of a co- generation system 1 in series, the temperature TH of hot waste water, which flows through a part at the downstream side of the heat exchanger 3 for supplying hot-water of the waste heat line L1, is detected by a temperature detecting means 9 arranged near the outlet port of the heat exchanger 3 for supplying hot-water, which is interposed at the downstream side of the waste heat line L1. The flow rate F1 of the hot waste water, supplied to the hot-water heating absorption refrigerating machine 2 interposed in the upstream side of the waste heat line L1, is determined the detected temperature TH of the hot waste water while the flow rate F1 of the hot waste water, supplied to the hot-water heating absorption refrigerating machine 2, is regulated on the basis of the determined flow rate F1.

摘要： PURPOSE:To provide a novel absorption refrigerator for a double effect cycle, which requires neither a high-temperature heat source nor high-pressure vapor such as those required for a conventional absorption refrigerator for a double effect cycle and which has been improved so as to have a more excellent result coefficient than that in a single effect cycle. CONSTITUTION:An absorption refrigerator no comprises a condenser 26, an evaporator 12, an absorber 14, a low-temperature regenerator 20, a high- temperature regenerator 14, a high-temperature heat exchanger 22 and a low- temperature heat exchanger 18. In this absorption refrigerator 10, a second absorber 32 and a third regenerator 28 are provided between the condenser 26 and the low-temperature regenerator 20 and between the condenser 26 and the high-temperature regenerator 24, respectively, and a third heat exchanger 30 is provided between the second absorber 32 and the third regenerator 28.
