【摘要】 卧式冷柜因其结构特征,一直采用直冷的制冷方式,内胆结霜后需要人工除霜,费时费力。本文设计了适用于卧式冷柜的顶部送风底部回风的立体射流风冷无霜技术,解决卧式冷柜结霜以及箱内温度均匀性差的技术难题。通过仿真发现,箱内温度呈上低下高的趋势,在43℃环境温度下,箱内最大温差为1.63K。基于此技术设计了280L卧式冷柜,经测试43℃箱内最大温差1.9K,与仿真结果仅差0.27K,且温度分布趋势与仿真结果一致。更多还原

【Abstract】 Because of the structure,chest freezer always uses direct-cooling refrigeration method. The liner will frost and need artificial defrost,which is wasting time and energy.The 3D jet-flow frost-free wind-cooling technology,whose wind is supplied from the top of freezer and returned at the bottom,is designed for chest freezer in this paper to solve the technical problem of frost and poor temperature uniformity. In the simulation,the inner temperature tends to be lower in the top and higher in the bottom,and the maximum temperature difference is 1.63 K at ambient temperature of 43℃. Based on this technology,we design a 280 L frost-free chest freezer. After the test,the maximum temperature difference is 1.9 K at ambient temperature of 43℃,which is only 0.27 K different from the simulation results,and the temperature distribution trend is similar to the simulation results.更多还原
