Romanian Abstract: Optimizarea consumului de energie actual este unul din principalele preocupări ale specialiştilor din acest domeniu la nivel mondial. Începând cu anii ′70 a început să se realizeze importanţa şi necesitatea de a dezvolta o strategie de utilizare a energie electrice....

The exergetic model is superior to other methods of study of mining pneumatic networks thermal processes. It allows us to find out the energy losses and exergetic efficiency. Thus, we have more opportunities for increasing these installation performances

Most interesting appearance in under consideration exergetic concerning the helical screw compressor represents it the possibility identified the weakly point from the cycle of operation. The identification and then improvement weakly points will permit the utilization energies in superior...

In the present study explored the effects were obtained for two passive measures: improved thermal insulation and general tightness of the building. Were quantified comparative energy performance for building real reference building, energy efficient building and rehabilitation variants I and II.
