Definitions

  • an outlet 2 C is provided from which a poor ammonia solution is directed, via a sixth line 19 provided with at least one lamination valve 30 , to a poor solution inlet 10 A provided in the absorber 10 , after yielding heat to the fluids present in the generator in a central portion 2 D thereof.
  • This introduction point is particularly advantageous when located in a point of the circuit 16 A, 16 B in which the solution present therein has a temperature close to that of the temperature resulting from mixing the two flows, i.e. the refrigerant flow and the solution flow.
  • adiabatic mixing of two liquid flows [for example 44% NH 3 in the solution, 99% NH 3 in the refrigerant] results in a flow at a temperature greater than the two inlet temperatures.
