摘要/Abstract

摘要： 冷藏陈列柜应用广泛,由于风幕的存在,导致了其较高的能耗。在运行过程中,冷藏陈列柜的性能会受到许多因素的影响。因此,利用验证的模型和响应面法（RSM）,充分讨论了工况参数（蒸发温度、风扇流量、环境温度和环境湿度）对热夹带因子（TEF）、能耗和温度均匀度的影响,并对其进行了多目标优化。结果表明：蒸发温度对TEF、能耗及温度均匀度都有较大的影响;风扇流量和蒸发温度的交互影响对三项性能指标均有较大的影响,而风扇流量和环境温度的交互影响仅对TEF有较大的影响。与基本条件相比,优化后的参数可使TEF降低22.07%,能耗降低37.06%,温度均匀度降低0.48℃。

Abstract: Refrigerated display cabinets are widely used. Due to the existence of wind curtains, their energy consumption is high. During operation, the performance of refrigerated display cabinets will be affected by many factors. Therefore, using the validated model and response surface method (RSM), fully discussed the influence of operating conditions parameters (evaporation temperature, flow rate, ambient temperature and ambient humidity) on thermal entrainment factor (TEF), energy consumption and temperature uniformity, and carried out multi-objective optimization. The results show that evaporation temperature has great influence on TEF, energy consumption and temperature uniformity; The interaction between flow rate and evaporation temperature has a significant impact on the three performance indicators, while the interaction between flow rate and ambient temperature only has a significant impact on TEF. Compared with the basic conditions, the optimized parameters can reduce TEF by 22.07%, energy consumption by 37.06%, and temperature uniformity by 0.48℃.
