W artykule przedstawiono przegląd aktualnego stanu wiedzy w zakresie właściwości nanopłynów chłodniczych. Analiza dotyczy zarówno wpływu nanocząstek na właściwości termodynamiczne nanopłynów chłodniczych, jak i na intensywność wymiany ciepła. Na podstawie wyników badań rożnych autorów stwierdzono, że wzrost stężenia nanocząstek zawieszonych w cieczy bazowej - czynniku chłodniczym - wpływa znacząco na wzrost wymiany ciepła. Podane przykłady wskazują na wzrost wartości współczynnika przejmowania (wnikania) ciepła nanopłynów chłodniczych w warunkach ich wrzenia w objętości jak i w przepływie. Podkreślono konieczność prowadzenia dalszych intensywnych badań eksperymentalnych i teoretycznych z nanopłynami chłodniczymi.

An overview of the current state of knowledge on nanorefrigerant properties in this article is presented. The analysis applies the impact of nanoparticles on the thermodynamic properties of nanorefrigerant and their influence on heat transfer intensity. Based on the results of various authors it was found that the increase in the concentration of nanoparticles suspended in a base liquid - refrigerant - increase significantly the heat transfer. Presented examples pointed the increase of the nanorefrigerant heat transfer coefficient under their pool boiling and flow boiling. The need for further intensive experimental and theoretical research on nanorefrigerants properties is stressed.
