Implementación de un módulo didáctico de un sistema de aire acondicionado tipo split de refrigerante r290 : sistema de monitoreo con arduino mega.

Abstract

The present degree project was developed using industrial instrumentation's regulations and concepts, for the construction of an embedded monitoring system to be implemented together with the other components of the didactic module of a Split system with R290. According to the split-type air conditioning equipment data sheet, it was determined that a 230 (VAC) power supply with a consumption of 6.7 (AAC) is necessary. The sensors were selected to measure voltage between 0 to 250 (VAC), current between 0 to 30 (A) and temperature between 0 to 1024 (°C), as well as a set of screens that allow visualizing the operating characteristics of the didactic module. Once the elements had been selected and a prototype designed, a panel with dimensions of 30 * 20 * 8 (cm) was manufactured containing all the elements of the system and, subsequently, it was installed in the module. in the performance tests, it was verified that the different sensors and screens communicated correctly. Also it was verified that the sensor's values had a relative measurment error less than 5.00%, comparing them with theoretical values and those measured with additional instruments. Subsequently, user's guiede and maintenance manual were done for each componentof the didactic module. Finally, it is concluded that with the desing and algorithm implemented, the monitoring system meets the objective of monitoring temperatures in the refrigeration cycle, in addition to the electrical parameters of the condensing unit of the Split equipment.
