Implementación de un módulo térmico para mejorar las condiciones de confort del laboratorio de diagnóstico técnico y eficiencia energética de la Facultad de Mecánica

Abstract

The objective of this research work was to implement a thermal module to improve comfort conditions in the Technical Diagnosis and Energy Efficiency Laboratory at Mechanics Faculty. It was proposed to strengthen knowledge about the operation of a refrigeration system. The development of the work included the calculation of the thermal load through the use of software, the selection of elements and equipment based on the cooling and heating load. They allowed the operation of the equipment as an air conditioner and the construction of the thermal module under the principle of operation of an ideal vapor compression refrigeration cycle. The laboratory guides for the thermal module, the operation manual and the maintenance plan were elaborated. By means of control elements, the performance tests were carried out where the thermal module works as a cooling or heating system, thus allowing a temperature variation in cooling mode of -3.4ºC in a time period of 24 minutes, obtaining thus, an ambient temperature in the laboratory of 20ºC. In the same way the operating tests were carried out in heating mode, obtaining a temperature variation of 4.3ºC in 20 minutes, achieving an ambient temperature in the laboratory of 28, 3ºC. It is concluded that the built thermal module maintains an ambient temperature in the laboratory of 20ºC in cooling mode and a temperature of 28.3ºC in heating mode. Using the laboratory guides the understanding of a basic refrigeration system was helped, knowing its main components, its principle of operation and what are its possible failures and breakdowns. For greater module efficiency, greater thermal insulation is recommended to prevent the entry of external temperatures of laboratory.
