Free Cooling using air as a refrigerant in supermarket cabinets
Air is not usually considered a ‘secondary refrigerant’ yet it is hard to find an application where air is not the medium of heat exchange. By supplying tempered air from a central plant air handler, ‘free cooling’ technologies commonly found in air conditioning applications can be employed into display cases. The iAir system installed in a recent pilot project for a major supermarket retailer is the marriage of these principles.
The paper discusses the combined technologies developed and employed in this alternative approach to supermarket refrigeration and outline the advantages of this system as well as the technical challenges encountered in the design. It compares the actual field results from the case study against the system’s theoretical performance model and those of standard and optimised conventional DX refrigeration solutions.
