Possible Schemes and Effects in Improving Temperature Uniformity in Indirect Cooling Wine Cabinet
The development of a high-quality wine cabinet requires a method to make the temperature distribution in the cabinet as uniform as possible. In this study
basic ideas for achieving a uniform temperature in a wine cabinet are presented
including a uniform transport of cold air
avoiding the sinking of cold air
reducing door heat leakage
and enhancing the air turbulence. In addition
preliminary schemes are illustrated accordingly
including the arrangement of the air outlet
the division of space
the air curtain on top of the cabinet
and the transverse direction of the air outlet. An optimized scheme was obtained through a comparison and analysis of the simulation performance of each scheme. The results show that the combination of four preliminary schemes can achieve the best temperature uniformity in a wine cabinet. A performance test of a 389 L wine cabinet under a set temperature of 8 ℃ shows that the maximum temperature difference can be reduced from 12.6 ℃ to 2.0 ℃ through the optimized scheme at an ambient temperature of 32 ℃. It was verified that the optimized scheme is able to improve the temperature uniformity in a wine cabinet effectively.
