Abstract

The use of energies from renewable sources, as an alternative to those obtained from fossil fuels, represents a sustained concern in the world scientific environment, this action being a particularly important objective at present, especially in the context of increasingly acute manifestations of the effects of climate change. The recovery and use of thermal energy developed in the composting process of biodegradable and solar waste is a current concern of the research environment in the field. In this paper we want to present some research on the recovery of thermal energy from the two renewable energy sources mentioned in order to use thermal energy for the production of the agent that can be used in the current activity of individual agricultural and livestock farms as well as in households, for the preparation of domestic hot water and heating of living spaces, greenhouses, and solariums. The paper presents the current state of research, some theoretical considerations regarding the thermodynamic phenomena that occur in the thermal energy recovery process, a modulated system for the recovery of thermal energy from the composting process and solar energy, experimentation in real operating conditions, the results and their interpretation and related conclusions.

Abstract in Romanian

Utilizarea energiilor din surse regenerabile, ca alternativă la cele obținute din combustibili fosili, reprezinta una din preocuparile sustinute ale mediului stiintific mondial, această actiune fiind un obiectiv deosebit de important la ora actuala, mai ales in contextul manifestarii tot mai acute a efectelor schimbarilor climatice. Recuperarea si utilizarea energiei termice dezvoltata in procesul de compostare a deseurilor biodegradabile si a celei solare, reprezinta una din preocuparile actuale ale mediului de cercetare din domeniu. În această lucrare ne propunem să prezentăm câteva cercetări privind reacuperarea energiei termice din cele doua surse de energie regenerabila menționate ȋn vederea utilizarii acesteia pentru producerea de agent termic care poate fi utilizat în activitatea curentă a fermelor agricole si zootehnice precum si in gospodariile individuale, pentru prepararea apei calde menajere si a incalzirii spatiilor de locuit, sere, solarii. In lucrare se prezinta stadiul actual al cercatarilor, cateva considerente teoretice privind fenomenele termodinamice ce se manifesta ȋn procesul recuperarii energiei termice, un sistem modulat de recuperare a energiilor termice din procesul de compostare si a celei solare, experimentarea acesteia in conditii reale de functionare, inregistrarea rezultatelor, interpretarea acestora si concluziile aferente.
