Laboratory vs. operation in real store environment According to the ISO 23953-2 standard Appendix B, there are significant different operation conditions between lab and store operation, especially for remote cabinets. The following section describes and explains the difference to the application in the field. Difference between laboratory and store data for remote cabinets The conditions of a remote a in the store differ greatly from the lab conditions. Usually, the cabinets in a store are multiplexed, located against a wall and the ambient conditions are lower. Using direct lab data for remote cabinets would lead to oversizing of piping and compressor racks. Based on this, CCR provides for E6 remote cabinets in the technical data sheets rack sizing data for the standard configuration at store condition 25°C / 60% rel. H. and 22°C / 55% rel. h. This data is available and optimized for each investment and life cycle. Based on CCR’s leading expertise in refrigerant system design, our general recommendation is: Rack design data 25/60 application: Stores in warm climates, stores with difficult climate situations, cabinet in a non-ideal place (high humidity, high temperature, close to a door, etc.) Rack design data 22/55 application: Store in middle and north Europe, stores with moderate climate (with air conditions, remote multiplexing cabinets) Technical data for plug-in cabinets To have comparable energy consumption within the CCR range, we specify the energy consumption for the standard configuration of plug-in cabinets, according to ISO 23953 and climate class 3 conditions. This makes the data comparable; however, the real energy consumption in a store is usually lower. Influence of the cabinet installation on the performance The installation can have significant effects on the energy and temperature performance. There are some requirements which need to be kept to ensure that the cabinets are working properly. Do not install the cabinet outside or next to heating radiators or other heat sources Keep a distance from the wall as indicated in the operating manual Avoid direct sunlight radiation impact Keep free the air intake and outlet area (only plug-in)
CCR internal testing To ensure a long lifetime and proper operation, CCR has defined internal standards for robustness and stress tests of a cabinet as well as components. Static robustness test To test the cabinet and shelf strength, all shelves are loaded with a certain weight for several days. The deflection of brackets and shelves is checked under load and after unloading the cabinet. Only if the cabinet deflection and deformation stay within the small tolerances defined by the CCR quality department, the cabinet will be released to the market. With high requirements on cabinet stability and strength, CCR ensures a high-quality product, safe and stable for years of operation. Dynamic testing of doors and lids The door opening test makes it possible to simulate several years of usage that our doors, hinges, and handles are likely to experience within just a few weeks. During the test, the system is continuously monitored and checked in terms of abrasion, break / damage and deformation. The system will only pass the internal qualification if it can resist several simulated years in the tough life of a supermarket. For double glass doors, CCR requires additional tests to ensure that the sealing works properly, and the doors do not get condensation between the glasses after some years. Packaging and shipping test Before each serial launch, CCR conducts a special packaging and transportation test. This happens with one or several cabinets in a truck going on a defined road with various road conditions. After the transport, the cabinet and the packaging are checked visually. This ensures that the cabinets will arrive to our customers in the same condition as they were packaged in the factory. CE (Conformité Européenne) certification The CCR cabinets are compliant with the relevant standards or parts of the standards, as confirmed with the CE declaration of conformity: ISO 23953-1 (Refrigerated display cabinets, general) ISO 23953-2 (Refrigerated display cabinets, requirement) EN 60335-1 (Household and similar electrical appliances. Safety. General requirements) EN 60335-2-89 (safety requirement for households and similar electrical appliances, particularly for commercial refrigerating appliances) To ensure maximum safety, all plug-in cabinets with flammable refrigerant are additionally CE certified by an independent body. Factory certifications All CCR cabinet factories have a certified quality management and environmental management systems • EN ISO 9001 (General quality management system) • EN ISO 14001 (Environmental management systems)
