Diseño y construcción de un prototipo de expansor compresor de aire como base para el desarrollo futuro de máquinas triatérmicas

Abstract

The requirement to make a prototype of a compressor expander was born with the need to evaluate possible elements that allow the generation of energy on a small scale and the future use within other machines or systems that allow to take advantage of the residual energy emitted to the environment. Prior to the construction of this prototype, a design that meets the requirements to take advantage of the waste gases emitted by other thermal machines on a micro scale was initially evaluated through the use of CAD software. A double chamber piston expander with a maximum output power of 100 W was built. The prototype together with the necessary instrumentation to obtain the indicated pressure in the cylinders was built and tested in the faculty's laboratory. Measurements of indicates pressure and piston position were made for a combination of rotational speeds and inlet pressures. After data post- processing, experimental yields were obtained in the range of 50 percent to 70 percent, according to the data provided by JF Oudkerk, R Dickes, O Dumont y V Lemort, in other studies for other types of expanders.
