Title:

IMPACTS OF SUBSTITUTION OF EQUIPMENT IN ENERGY CONSERVATION

Summary :

ABSTRACT. IN DAIRY PLANTS, DUE TO ITS ENERGETIC BEHAVIOR, THE COMPRESSORS FOR REFRIGERATION SYSTEM HAVE A SIGNIFICANT PARTICIPATION. FROM THIS OBSERVATION, IT BECOMES INTERESTING TO EVALUATE THE POTENTIAL OF SAVE ENERGY OF THESE MACHINES CAN OFFER. THIS WORK IS BASED ON THERMODYNAMIC THROUGH THE FIRST AND SECOND LAW, IN WHICH THE ANALYSIS TAKE ON THE QUANTITATIVE AND QUALITATIVE ASPECTS, RESPECTIVELY, ASSOCIATED WITH CONCEPTS OF ELECTRICAL MACHINES TO THE STUDY OF CIRCUITS AND DEVICES INVOLVED. WITH THE INFORMATION OBTAINED, LIKE TEMPERATURE AND PRESSURE, OTHER PROPERTIES WILL BE OBTAINED, LIKE ENTHALPY AND ENTROPY, THAT TOGETHER WITH OTHER PHYSICS MAGNITUDE, WILL PARTICIPATE IN ENERGETIC AND EXERGETIC BALANCE. FROM THESE ANALYSIS, THE PRESENT CONDITIONS OF EQUIPMENT INVOLVED WILL BE EVALUATED, AND USING THE SAME CONCEPTS, IT WILL BE VERIFIED THE EQUIPMENT AND AVAILABLE ACCESSORIES IN THE MARKET, POSSESSING RECENT TECHNOLOGY. ONCE THE RESULTS TECHNICALLY COMPARED, APPEARING MORE THAN ONE OPTION, THE SELECTION WILL BE BASED ON CONCEPTS OF ECONOMIC ENGINEERING; THE REMUNERATION OF EACH INVESTMENT WILL BE VERIFIED, TAKING INTO ACCOUNT THE INTEREST TAXES, COSTS AND PAY BACK. KEYWORDS: ENERGY CONSERVATION, RATIONAL USE OF ENERGY, ENERGY GENERATION TECHNOLOGIES, ENERGY PERFORMANCE IMPROVEMENT
