摘要

基于鼠笼式丝管冷凝器周围空气温度场的实验研究结果

为优化空气侧流场和强化换热

对冷凝器结构进行改进

即在冷凝器下游增设了外绕泡沫挡圈以增加通过径向可有效换热的空气流量

同时在其上游最内圈设置泡沫堵芯以减少通过轴向基本不参与换热的空气流量。结构改进前后的实验结果表明:通过对冷凝器结构的改进

冷凝器出口温度降低约0.7 ℃

开机工作系数减小了2.02%

冰箱耗电量降低了2.37%。实验数据还表明

外绕挡圈和泡沫堵芯能有效减少停机时从压缩机仓和冷凝器下游向冷凝器出口所在的上游扩散的热空气量

有利于下次开机后冷凝器快速散热和降温。

Abstract

The air temperature filed around a spiral wire-on-tube condenser of a no-frost refrigerator was investigated experimentally

and then the condenser was optimized accordingly to enhance air-side heat transfer. A wind-broken foam ring was wrapped around downstream part of the condenser to increase airflow in the radial direction

and a wind-broken foam block was set in upstream part of the condenser centerline to reduce airflow in the axial direction

which nearly does not transfer heat. The results show that the condenser outlet temperature decreases by about 0.7 ℃

the compressor operation time ratio drops by 2.02%

and the refrigerator's electricity consumption descends by 2.37% after the optimization. Moreover

both the wind-broken ring and the wind-broken block effectively prevent high-temperature air around the compressor and downstream part of the condenser from flowing to upstream part of the condenser during the outage of compressor

which benefits the heat transfer of the condenser in next operation.
