W pracy przedstawiono wyniki badań eksperymentalnych wymiany ciepła oraz spadku ciśnienia podczas skraplania mieszanin zeotropowych R407C i R410A w minikanałach rurowych o średnicy wewnętrznej d = 0,31 ÷ 3,30 mm. Wyznaczono wartości lokalne i średnie współczynnika przejmowania ciepła a i oporów przepływu (Δp/L) w całym zakresie zmiany stopnia suchości (x = 1÷ 0). Na podstawie uzyskanych wyników badań...
In this paper a short literature review on the solar collectors has been presented. A classification has been made according to application areas: heating in industrial processes (i.e. drying of agricultural products, biomass drying) or in civil engineering (i.e. air conditioning, space heating). Solar collectors have been classified in regard to their design: cover material, direction and type of...
