ALTERNATIVE OPTIONS FOR PLUG-IN, SMALL COMMERCIAL CABINETS IN HIGH AMBIENT AREAS… SOUTHERN AFRICAN REGION by Roy Singh
SELF CONTAINED REFRIGERATED CABINETS… These products are produced in low volumes - high refrigerant usage. 1.Integral condensing unit 2.HCFC to R600a/R290/R744 3.Charge < 150g for HC 4.Twin circuit for larger cabinets “ Plug & Play “
Challenges… Product Mostly Independent companies -System redesign – Insufficient technical know how, no partner collaboration as in large multinational companies. Local R&D engineering team. Compact design (cassette) – Electrical components and refrigerant in close proximity. SOI - Leak simulation test critical – Expensive test equipment. Tested at production facility. Testing – IEC & CE - Limited locally equipped test house
Production machinery & Product Support High cost of safety/ventilation/charging equipment – less complex machines for lower volume batch production.( < 48kg HC ) Availability of Refrigerant,Spares & Components for replacement in remote areas. Training &Technician Certification. Not same as domestic refrigeration techs which were trained- totally different cluster.
