Traditional Medical Refrigerator 

Traditional cooling technology has been used in laboratory and blood bank refrigerators for many years. This approach relies on fixed capacity compressors and hydrofluorocarbon (HFC) refrigerants to achieve the required temperature range. While these systems achieve acceptable results, this type of design consumes more energy than newer approaches.

The refrigerants that have traditionally been used have higher global warming potential and heat rejection than alternative coolants. Innovations in refrigeration technology have now been developed that make it possible to maintain tight temperature ranges while at the same time minimizing energy consumption, heat output, and global warming potential.
