Résumé

Supermarket refrigeration systems typically consist of a number of display cabinets. These display cabinets interact thermally with the room in which they are located. This thermal interaction is generally described as a refrigerant load acting on the display cabinets. A mathematical description of the refrigeration load can be used for multiple purposes. It is an integral part of dynamic models of display cabinets, but can also be used for fault detection, benchmarking or systems optimization. If laboratory measurements are not available to identify the necessary parameters, the parameters of the refrigeration load model must be identified from monitoring data. This paper demonstrates how to identify refrigeration load parameters from monitoring data, using data from a Danish supermarket. The paper also highlights some of the main challenges with the dataset. The prediction accuracy achieved is satisfactory, although some inherent challenges remain.
