The objective of this study is to analyze and simulate the behavior of R134a refrigerant
in a capacitor located in a water storage tank, using the method of computational fluid
dynamics CFD. The following experimental data obtained in an experimental
laboratory was considered; temperatures after entering and leaving the condenser,
which are 39.85 and 14.85 °C respectively; the work input pressures which are 913
kPa, with a pressure drop of 861 kPa at the condenser outlet due to the condensing
effect of the R134a refrigerant and its technical characteristics.
The refrigerant placed inside the condenser is a limiting factor in order to maintain a
proper follow up during the phase change of the fluid; from the simulation we can
obtain clear images of the condensation patterns occurring around the tenth coil, which
reach a temperature of about 22 °C, and a pressure of 875 kPa; these values can be
observed in the color scale on the figures in Chapter 3. Volumetric flow data ranges
from 2 1.557 10 to 1 9.91 10 % for the refrigerant vapor phase, while for the liquid
phase it ranges from a similar value of 0.00 to 1 9.754 10 % which allows us to
understand the great amount of steam at the capacitor input and the completely
condensed coolant outlet.
Once the simulation parameters are set, ANSYS FLUENT software is used to
experimentally evaluate the actual behavior of the refrigerant, where we conclude that
the capacitor is the element which delivers a heat flux of 7.29 W. Due to the phase
change, speeds inside the capacitor range from 0.00 to 2 m s-1, as this values are
reached in the center of the fluid. |
