APPARATUS AND METHOD FOR CONTROLLING THE FLOW OF POOR DISSOLUTION IN AMMONIA-WATER ABSORPTION CYCLES.

摘要

Ammonia-water absorption cooling and / or heating apparatus comprising: an absorber assembly (10), a generator set (11), a condenser (14), an evaporator (20), a cooling loop comprising pipes (41 , 42, 43, 44) to direct the refrigerant between said absorber assembly, generator set, condenser and evaporator, an absorption fluid loop to direct the absorption fluid between said absorber assembly and said generator assembly, including said fluid loop of absorbing a first pipe (46) to direct the ammonia rich absorption fluid from the absorber assembly towards the generator assembly and a second pipe (45, 47) to direct the ammonia poor absorption fluid from the generator assembly to the absorber assembly , and a valve assembly (60, 56) comprising one or more valves that act in a complementary manner with the second pipe to open and close to control the flow of the poor absorption fluid therein, the apparatus being characterized by a detecting device (62, 53) positioned to detect a condition of said ammonia-poor absorption fluid upstream of said one or more valves and operatively communicating with said a or more valves to open and / or close one or more valves in response to said detected condition, said condition being a temperature, concentration or property or correlated condition of the ammonia-poor absorption fluid to maintain the concentration of ammonia in the poor solution. within the desired range.
