Optimización De Equipos Térmicos Y Termodinámicos Con Enfoque Mecatrónico

Abstract

This paper is focused on providing optimization tools through a mechatronic approach for heat pump systems with domestic applications; the particular case presented in the work is the provision of domestic hot water by means of a heat pump with a capacity of 5 kW. Fundamentally, the work starts with a bibliographic review where a greater emphasis is placed on the thermodynamic process of the system to be studied, and then continues with the methodology, which is subdivided into a quasi-static analysis of the system and a dynamic analysis of the same. The proposed methodology considers the application of the computational software MATLAB for the optimization of the system, considering that the system is applied to thermophysical conditions of Quito; in the optimization process variables such as the absence or presence of solar assistance in the evaporator, the type of insulation of the water heater containing the sanitary water and the size of the insulation thickness are considered. Finally, the results were obtained by performing a sensitivity analysis considering a variation of the variables mentioned above, where the heat pump system with solar assistance, insulation in the water heater made of expanded polyurethane material with a thickness of 14 [cm] presented a considerable improvement of 50% of the operating performance factors in relation to the preliminary data yielded by the initial conditions that were considered for the heat pump system
