Promotion of energy efficient display cabinets.

Author(s) : AXELL M., FAHLÉN P. O.

Summary

To promote energy efficient commercial refrigeration, NUTEK of Sweden has staged a competition for indirectly cooled vertical display cabinets. The primary target was to decrease the use of electricity. The winner achieved 1745 kWh/m, 50% less than the best screening result. The direct electric input to this cabinet, i.e. to fans, lighting and frame heating, was down to less than half the screening level. Nevertheless, it still had the highest value of illumination. The new designs have much improved night coverage (air infiltration). Furthermore, attention to coils and air curtains permit operation with a warmer brine, reducing temperature gradients as well as defrosting and total energy input.
