Документ Влияние эффективности регенератора на энергетические показатели холодильных машин и тепловых насосов(НТУ "ХПИ", 2009) Братута, Эдуард Георгиевич; Харлампиди, Дионис Харлампиевич; Шерстюк, А. В.A genaralized performances for complex estimate of the influence of thermalphysics properties of working fluids on the energy effectivenes of refrigeration plants and heat pump installations have been found. The calculation investigation of the influence of suction-line/liquid-line heat exchanger in the refrigaration cycle on the energy effectiveness of refrigeration plant and in the wide range of change of the evaporation and condenser temperatures for different refgarants have been taken into account.Документ Термодинамическое тестирование сверхкритических циклов холодильных машин и тепловых насосов(НТУ "ХПИ", 2011) Шерстюк, А. В.; Харлампиди, Д. Х.; Братута, Эдуард ГеоргиевичThe analysis of regime paramaters influence on energy and exergy efficiency of refrigerating mashines and heat pumps that works by overcritical cycle with R744 as refrigerating medium has bee carried out. The methos of thermodynamic analysis of overcritical cycles has been worked out. The influence of saturation pressure for overcritical cycle on exergy losses distribution in refrigerating mashines and heat pumps has been studied out.
