Tarifas exergéticas para irrigação.

Abstract

Presently with rare exceptions, the energetic analysis are performed based on the First Principle of Thermodynamics, that considers the energy balance. On the other hand, the energetic analysis based on the Second Principle of Thermodynamics deals with the energy degradation, i. e. , the quality of the energy. This article recommends that the efficiency as a system planning parameter be considered by the view of the Second Principle of Thermodynamics. It is recommended that the electric rate in particular as well as the other energetic sources in general be priced as a direct function of the inverse of the exergetic efficiency. It is given particular attention to the simulation of the use of exergetic rates to the irrigation activity in contrast to the other economic sectors. It is shown here, that the implementation of exergetic rates will prize the activity irrigation, followed by the industrial sector as opposed to residential and commercial sectors.
