Análise das perdas térmicas nas tubulações de um ar condicionado split

Abstract

In the later years the use of air conditioning system and refrigeration in residences ambient, commerce and industrial have been increasing. This causes a negative impact in the world energetic matrix, so the manufacturers of air conditioning and refrigeration system has sought to produce more efficient equipment, and consequently less energy consumption. However, the inappropriate use of these devices causes impact in its working. The present work has as goal to exhibit the impact of thermal losses causes in a Split bench air conditioning. It will be show through experiments done on the Split air conditioning, where its piping are thermal insulated. With help of thermometers and manometers, it was possible obtain the temperature and pressure in inlet and outlet from each component of the system. Done this, it was possible obtain values of specific enthalpy in each point, which allowed to compute the energy losses along piping, as well as obtain the coefficient of performance. What can be verified in this work it was the negative impact that the lack of thermal insulation caused in the performance of the bench air conditioning.
