Devices for injecting liquid ammonia into thermopressor coolers

The survey of works, which were carried out in thermal engineering, and related to characteristics of mixing contact heat exchangers is given, the condition to calculate nozzle diameter to inject liquid ammonia into evaporating chamber of thermopressor type intermediate cooler is shown. The properties of devices for liquid atomizing are considered, Laval nozzle has been grounded on the principle of discrete pulse energy input and transformation for injection and atomizing of adiabatically boiled up ammonia flow. The description of experimental layout is shown, also results, comparisons and conclusions are presented, calculated diameters presented in the table.
