<cfAbstr cfLangCode='RU' cfTrans='o'>Проведен анализ эффективности использования вихревой трубы в тепловом
насосе на диоксиде углерода. Тепловой насос предназначен для одновременной
выработки теплоты на одном температурном уровне и холода на двух температурных
уровнях. Предлагаемая гидравлическая схема сравнивается с известными тепловыми
насосами, использующими эжекторы. На конкретном примере показано, что схема с
вихревой трубой имеет больший коэффициент тепловой эффективности.</cfAbstr>
<cfAbstr cfLangCode='RO' cfTrans='o'>Este efectuată analiza eficacităţii de utilizare a tubului de vârtejuri în pompa de căldură cu dioxid de
carbon în calitate de agent frigorific. Pompa de căldură este destinată spre producerea simultană a căldurii la un
nivel de temperatură şi frigului pe două nivele de temperatură. Schema propusă este comparată cu pompa de
căldură, care utilizează ejectori. La un exemplu concret este demonstrată, că schema cu tub de vârtejuri are
coeficientul de performanţă termică mai mare decît cea cu ejectoare.</cfAbstr>
<cfAbstr cfLangCode='EN' cfTrans='o'>It is performed analisys of the use of efficiency of the use of vortex tube in heat pump with carbon
dioxide as the refrigerant. Heat pump is desinated for parallel production of of heat on one temperature level and
cold on two temperature levels. Scheme is compared with heat pump in which ejectors are used. It is demonstrated
on the exemple that scheme with the vortex tube has COP increased comparitive with those with ejectors.</cfAbstr>
