本文将CFD与冷却盘管子模型相结合，建立了多层中温陈列柜的模型。分布式方法用于开发冷却盘管模型，空气侧输入来自CFD模型的输出。因此，来自冷却盘管模型的空气侧输出用于更新CFD模型的边界条件。为了验证此柜模型，选择了一个带有次级制冷剂冷却盘管的多层中温展示柜作为原型，并安装在空调室中。在恒定的空间空气温度和不同的相对湿度下进行了广泛的试验。通过与流路不同位置的空气参数、制冷剂和食品温度等测试结果进行比较，对机柜模型进行了验证。因此，验证后的模型可用于探索和分析机柜在各种操作和设计条件下的性能和控制策略。
In this paper, the model for the multi-deck medium temperature display cabinets is developed with the integration of CFD and cooling coil sub-models. The distributed method is used to develop the cooling coil model with the airside inputs from the outputs of the CFD model. Inversely, the airside outputs from the cooling coil model are used to update the boundary conditions of the CFD model. To validate this cabinet model, a multi-deck medium temperature display cabinet refrigerated with a secondary refrigerant cooling coil was selected as a prototype and mounted in an air conditioned chamber. Extensive tests were conducted at constant space air temperature and varied relative humilities. The cabinet model has been validated by comparing with the test results for the parameters of air at different locations of the flow path, and temperatures of refrigerant and food product, etc. The validated model is therefore used to explore and analyse the cabinet performance and control strategies at various operating and design conditions.
