Aircell System Claims 50% Energy Savings for Open Refrigerated Cases

Adande publishes research that it says proves significant energy benefit and temperature control

Refrigeration company Adande has published independent evidence that its patented Aircell air flow management system, designed for open-front multi-decks, delivers 50 percent energy savings compared with conventional open refrigerated cases.

Adande commissioned research firm RD&T to conduct tests under BS EN ISO 23953 comparing the performance of a 2,500 mm open-front remote multi-deck cabinet, commercially available within the United Kingdom (UK), with an identical model modified with the Aircell system.

After stable state running for 24 hours, the energy usage of each case was monitored over a further 24 hour cycle. Results for the baseline cabinet showed a refrigeration electrical energy consumption (REC) of 57.61 kWh/24h, compared with a REC of 27.41 kWh/24h for the cabinet modified with Aircell — an energy savings of over 50 percent.

The tests also monitored the temperature of Tylose ‘m’ packs loaded within the cabinets. The temperature of the packs in the baseline cabinet varied by 7.7°C, while the temperature of the packs in Aircell cabinet was within a band of just 3.2°C, demonstrating much tighter temperature control.

Adande’s managing director, Ian Wood, stated, “We believe that the results for the cabinet incorporating Aircell demonstrate the lowest energy consumption figures and the tightest temperature control seen on an open-front refrigerated multi-deck cabinet of this type.”

The RD&T data bears out previous independent tests carried out by another research lab, ECH Engineering Ltd., which established a REC of 48.00 kWh/24h for the baseline cabinet, compared with a REC of 29.72 kWh/24h for the Aircell model. In terms of operating temperature variation, ECH Engineering measured a range of pack temperatures of 9.5°C in the baseline cabinet and a band of 3.1°C in the Aircell cabinet.
