Descriere<br />

RO<br />

Micro-hydropower station provides kinetic energy conversion of<br />

river water into mechanical or electrical energy without building<br />

barrages. Increased efficiency is provided by blades aerodynamic<br />

profile and their optimum position for efficient conversion of water<br />

kinetic energy.<br />

Microhidrocentrala este destinată pentru conversia energiei cinetice<br />

a apei curgătoare a râului fără construirea barajelor. Eficienţa înaltă<br />

de conversie este asigurată de profilul hidrodinamic al palelor şi de<br />

reglarea lor în poziţii optime din punct de vedere al conversiei<br />

energiei cinetice a apei.<br />

Descriere<br />

RO<br />

Small wind speeds which are characteristic for the Republic<br />

of Moldova do not allow efficient utilization of the classical<br />

wind working elements. To increase the conversion<br />

efficiency of wind energy at speeds a new wind working<br />

element has been designed, based on combined effect of the<br />

Darrieus and Helical rotors. It has the shape of Darreus<br />

turbine with aerodynamic profile of blades in normal section.<br />

Vitezele mici ale vântului, caracteristice pentru Republica<br />

Moldova, nu asigură eficienţă înaltă de conversie a energiei<br />

eoliene cu organe de lucru clasice. Pentru a mări eficienţa de<br />

conversie a energiei eoliene la viteze V=2...5 m/s a fost<br />

elaborat un organ de lucru nou bazat pe acţiunea combinată<br />

a turbinelor Darreus şi elicoidală. Palele turbinei Darreus are<br />

profil aerodinamic în secţiune normală.<br />
