What are the advantages of plug-in refrigeration Vs conventional CO2?
At the heart of the plug-in approach is the flexibility offered by mobilisation of the furniture, providing retailers with the superior advantage to adapt their stores and department layouts according to changing assortments. This benefits both the consumer in terms of addressing their changing needs, but also the retailer, who saves money and energy efficiency over the long term due to the savings associated with part-renovations through the lifecycle of the store. With the trend toward smaller stores, the implementation of plug-in furniture for the whole store or single new department renovations is the easiest and smartest option available right now.
Long-term energy efficiency.
With typical CO2 systems, the plant is designed to supply optimum cooling according to the refrigeration needs of the store. However, when the retailer changes or adds more refrigeration, which has been the case for most retailers over recent years, the plant is no longer optimised for the increased supply requirement. Long runs of CO2 copper pipes are also fundamentally inefficient, which has a huge effect over its lifetime. With integrated cooling, the proximity guarantees efficiency of the unit and is consistently efficient throughout its entire life.
The Waterloop system.
Schweitzer has invested heavily into plug-in furniture in combination with waterloop systems, which make the use of plug-in furniture a genuine alternative for larger footprints. The waterloop requires no plant, just a small unit that cools the water before running through flexible pipes, then through each piece to cool the integrated unit within the furniture. By carrying away the heat they generate from the store, the waterloop helps to alleviate AC systems in the summer, while providing the option to use the generated hot water for heating in the winter. It’s a win-win regardless of the climatic conditions of the store locale. The pipes are easy to install, move & maintain, adding a huge amount of flexibility to the installation.
Long-term cost saving.
Unlike conventional CO2 systems, plug-in furniture requires no copper pipes from the floor, in-fact, all the services such as data and electrics is serviced from a flexible grid in the ceiling, including waste, which is pumped up and away from the retail area. If you take a typical store with a 10-year lifecycle, you can be sure that there’ll be countless alterations to the layout, each time resulting in the need to bring in specialist plumbers at great expense & material cost. Plug-in systems can be moved or maintained by non-engineers, resulting in no damage to floor surfaces and with layout changes managed in a far quicker timeframe.
