The air temperature inside the refrigerator and the optimization of the flow field
Accurate, so after a study, the experimental program. Experiments Engineering, University of Karlsruhe, Germany, Thermodynamics and Refrigeration Institute standard testing room for the refrigerator. Table 2 lists the different spacing,tory burch uk, the inside temperature difference between the experimental values. Meanwhile,tory burch uk, inside the experimental test conditions for air cooling of 26 * 1 / 1998 of a circle sDe 20, DI-l0 Ju degree field when the gas was simulated with the corresponding results are listed in the table can be from the table be seen, the spacing for the temperature field does have a greater impact, in quantitative theoretical calculations to reflect on the impact the better. Huan weight between 2 long-term operating conditions for the poor shaggy ring box Ju De (mm) 001016Dl (mm) 0666DT (K) (experimental value) 2.42.84.96.1DT (K) (calculated value) 2 .32.64.8 & 2 V, the impact of thermal conductivity within the shelf within the shelf to improve the thermal conductivity,christian louboutin shoes, in theory, benefit the top and bottom shelf air heat exchange, thus facilitating a more uniform temperature inside. But in fact, this effect be? Within our shelves by changing the thermal conductivity, making it from zero value (mean adiabatic) change to correspond to the higher thermal conductivity of copper the value of thermal conductivity coefficients in each , then a OO000000OOO port 000D))) Elimination of the high flap flap Zhen Lin Gu I. . One by one. One. . . . . . :. . . . . . Rubidium-type ll: ll:: llllll: ll simulate different thermal loading conditions of the flow field. It was found that only when the heat load very hour (far less than the actual load),ropa ed hardy, not the same shelf thermal conductivity between the flow field only the more obvious differences. In general conditions, this difference is very limited, therefore, work in a normal refrigerator, the thermal conductivity of that shelf inside the refrigerator temperature field and flow field has no effect. VI Conclusion The structure of the traditional wire refrigerator shelf, the surface of the evaporator heat transfer coefficient is high and helps to reduce the size of the evaporator, but inside the large temperature difference between the upper and lower positions, and the overall temperature and flow inside placed inside the food market more vulnerable to the impact, so not suitable for large volume inside the refrigerator. Used to prevent air directly through the flat shelf,ed hardy tøj, generally, can help reduce the inside temperature difference between the upper and lower positions, but must be accompanied by a larger evaporator area. In this structure, the evaporator and the door shelf and the spacing between the temperature and flow field for a significant impact. When the distance is small, the air will be mainly in the flow between the adjacent shelf, the air and the evaporator heat transfer coefficient of the surface of small temperature difference is smaller box. When the distance increases, the flow field will be strengthened, the air is mainly along the evaporator surface and surface flow cabinets, air and surface heat transfer coefficient of the evaporator increases, the temperature difference between inside will also increase. Normal operating conditions for the refrigerator, the shelf for the thermal conductivity of the air flow field is negligible.
