Abstract
The thermal systems have their operation based on the variables, such as temperature and pressure, of their working fluids or refrigerants, in addition to their operational characteristics and properties. This work aims to develop a measurement tool, monitoring and diagnostics of temperature and pressure of thermal systems. First, using for example, generating diesel units (GDU) with diesel engines, as well as implementation in a HVAC system environment, specifically a split air conditioner in a test bench in Climatization and Thermal Comfort Laboratory – ClimatConT, from the Federal University of Pará – UFPA. The main goal of this work is the implement of a set of instruments and controllers that will form the Monitoring System for Temperature and Pressure Measurement, called SMTP, working with data acquisition, monitoring, measurement and analysis of operational parameters of thermal systems in operation. With SMTP is possible to perform monitoring and comparison of real-time operating conditions with the specific technical standards for the tests, in addition to identification of performance loss and possible failures, the tool should increase the availability and reliability of the system. In this first moment as a case study the SMTP was installed in internal combustion engines of diesel thermoelectric power plants – TPPs, aiming to reduce the operational and maintenance costs, besides providing the application of predictive maintenance techniques in power generation systems, furthermore, with the adaptations, the tool could work in other types of thermal systems as well.
