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.</p>liquid ammoniacoolersthermocompressorheat exchangersevaporation chamberжидкий аммиакохладителитермопрессортеплообменникииспарительная камера
