Diseño de un sistema de calefacción solar para la cámara de secado en la empresa de curtiembre el AL-CE.

Abstract

Design of a solar heating system by the use of a flat plate solar collector under the Ecuadorian Construction Standard (NEC-10, 1996). It started from the conventional process that used liquefied petroleum gas (GLP) burning, in order to obtain the variables of temperature, time and humidity that define its process and replace them with another means of heat generation without losing the physical and chemical characteristics that dry leather requires. The solar model was coupled in the current installations where it has stopped working a heating system with steam generation, which made use of a cauldron. Its implementation started with the construction of the solar collector with materials of low cost and easy construction, a piping system that transports the transporting fluid, a storage tank where the generated heat and a system of internal pipes that are inside the drying chamber are stored. The heat transfer efficiency of the system was measured obtaining a value of 22º C for the drying process using solar energy, being less than. The 30º C required by the conventional system turning it into a process of slow drying. Using a fluid, the dry leather characterization was measured, where moisture after the drying process reaches 8.89%, obtaining a humidity reduction of 43.87% compared to the conventional system, which is 52.75%. It concluded that replacing the solar energy by the energy with which the drying system worked previously produces a product that retains its physical and chemical characteristics. It is recommended to coat the drying chamber with insulation in both walls and roof of the same to make the system more efficient and life is not affected by weather conditions or malfunction.
