The ammonia absorption type refigerating plant which utilizes the remaining heat of the exhaust

摘要

An ammonia absorption type refrigerating apparatus utilizing waste heat of exhaust, which consists of an ammonia solution circulation loop and an ammonia circulation loop, includes a waste heat generator (1), a finestiller (5), a regenerator (3), a solution throttle valve (4), ammonia throttle valves (11, 13), an evaporator (15), a solution pump (9), an absorber (8), a condenser (10), a generation-absorption heat exchanger (7) and an over cooler (12). In the ammonia solution circulation loop, an electric switch valve of the ammonia solution circulation loop (6) is connected in series in the pipeline between the outlet of the regenerator (3) and the top inlet of the generation-absorption heat exchanger (7); in the ammonia circulation loop, an electric switch valve of the ammonia circulation loop (14) is connected in series in the pipeline between the outlet of the condenser (10) and the inlet of the evaporator (15).
