RESUMEN: El uso de los extractores axiales en invernaderos para el control de temperatura y renovación de volumen de aire permite la recuperación de la energía eólica residual, esto representa una fuente constante de producción de energía limpia, y reducción de los costos de producción al bajar los costos de consumo de energía. El objetivo de este trabajo fue diseñar, construir y evaluar un sistema de recuperación de energía eólica residual en los invernaderos. Este sistema consiste en una turbina eólica colocada a una distancia óptima, un cono en la descarga de aire y un mecanismo para modificar el ángulo de aspas de la turbina eólica. Se analizó el balance de energía del sistema, midiendo los principales parámetros de energía, tales como: voltaje, amperaje, velocidad del aire y velocidad angular de los rotores. Las pruebas con la turbina eólica se realizaron en el sistema extractor de aire de un invernadero, sin cono y con cono. La implementación del sistema propuesto permitió recuperar la energía eléctrica del motor. Con el cono instalado, la energía eléctrica recuperada se incrementó en comparación que con el sistema de recuperación sin cono.
ABSTRACT: The use of axial extractors in greenhouses for temperature control and air volume renewal allows the recovery of residual wind energy, this represents a constant source of clean energy production, and reduction of production costs by lowering energy consumption costs. The objective of this work was to design, build and evaluate a wind energy recovery system in greenhouses. This system consists of a wind turbine placed at an optimal distance, an air discharge cone and a mechanism to modify the angle of the wind turbine blades. The energy balance of the system was analyzed, measuring the main energy parameters, such as: voltage, amperage, air speed and angular velocity of the rotors. The tests with the wind turbine were carried out in the air extraction system of a greenhouse, without cone and with cone. The implementation of the proposed system allowed the recovery of electrical energy from the engine. With the cone installed, the electrical energy recovered was increased compared to the recovery system without cone.
