Diseño y construcción de un equipo de evaluación del proceso de condensación con R600a y aceite miscible hasta el 5% utilizando una bomba de engranajes

Abstract

The system was focused on the design and construction of an evaluation equipment for a condensation process with R600 and miscible oil up to 5% will using a gear pump. In this research, we will be using systematic processes, which are applied over the study of the, which will help to obtain the desired information. The qualitative method for carrying out the research is acquired, the same one that tries to investigate the appropriate components that are required for the correct construction of the machine. The thermodynamic behavior of the refrigerant through the condenser is established and the characteristics required for the improvement of the cooling cycle must be determined. This refrigerant will be used as an alternative to the Refrigerant R134a. The thermodynamic study has been based on the cooling cycle consisting of a gear pump, two series evaporators type alloyed tube with a performance capacity of 589 W and a condenser with the same characteristics, connected by k-type pipes with dimensions of 3/8 inches and 1/4 inches in the Ecuadorian market. The main function of the equipment is to charge the R600a refrigerant system in the liquid state at the entrance of the gear pump which is where it will reach the evaporator by changing to the superheated state and entering the two capacitors, which will ensure its arrival in liquid state to avoid damage. Changes in viscosities have been noticed in the equipment when increasing PAO oil to R600a refrigerant that should be considered so that the work of the gear pump does not affect the system.
