AMMONIA WATER ABSORPTION REFRIGERATING DEVICE UTILIZING EXHAUST HEAT OF TAIL GAS

摘要

An ammonia water absorption refrigerating device utilizing exhaust heat of tail gas, comprises an ammonia water solution circulation loop and an ammonia circulation loop. In the cycle for ammonia water solution, before a cooled ammonia water strong solution from a solution pump (18) is heated by an exhaust heat generator (11), the strong sulution is preheated by a superheater (13), a rectifier (15), a generation-absorption heat exchanger (16) and a combination of a stripper (12) and the superheater (13). Cooling capacity of low temperature ammonia vapor from an evaporator (24) is withdrawn by liquid ammonia from a condenser (19) in a supercooler (20).
