HEAT EXPLOITATION AND RECOVERY FROM SECONDARY ENERGY SOURCES WITH HEAT DOWN POTENTIAL
The reduction of energy consumption or the heat recovery from different sources is an increasingly important activity both at EU. Facilities commonly used for heat recovery are heat exchangers, and heat pump. Starting from this paper, it was considered appropriate to approach a research on the heat recovery using heat exchanger form wastewater. The potential of wastewater, types of heat exchangers and their applications is discussed. In this study, is presented a reiew of heat exchangers are classified in detail based on multiple features, including utilization and construction, methodology.
Keywords: wastewater, heat recovery, energy, heat exchanger
Cuvinte cheie: apă uzată, recuperare căldură, energie, schimbător de căldură

THE FACTORS THAT INFLUENCE THE SOUND ABSORPTION COEFFICIENT OF MATERIALS
Starting from the premise that the sound absorbing materials are used in almost all domains of activity, we analysed the factors that influence the properties of sound absorbing materials: density, porosity, resistance to airflow, tortuosity, thickness and the placement of material.
Keywords: density, Sound wave absorption, the material structure
Cuvinte cheie: densitatea, absorbţia undei sonoare, structura materialului
