A new prototype of an absorption cooling system using NH₃/LiNO₃ was developed.

Falling films shell and tubes heat exchangers were used as absorber and generator.

Evaporator temperatures as low as 4 °C were achieved.

The COP varied between 0.27 and 0.62 depending on the system temperatures.

A flow recirculation in the absorber was implemented showing an increase in COP.
