Aircell system claims 50% better energy than conventional openfront multidecks

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


Refrigeration innovator, Adande has published independent evidence that its patented Aircell air flow management system, designed for open front multidecks, delivers 50 per cent energy savings compared with conventional refrigerated cases.

Adande commissioned research firm RD&T to conduct tests under BS EN ISO 23953 comparing the performance of a 2500 mm open-front remote multi deck cabinet, commercially available within the 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 saving of over 50 per cent.

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 deg C, whilst the temperature of the packs in Aircell cabinet was within a band of just 3.2 deg C.

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

The RD&T data bears out previous independent tests carried out by another research lab, ECH Engineering Ltd, 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 deg C in the baseline cabinet and a band of 3.1 deg C in the Aircell cabinet.

  • Let me tell you a fairy tale:
    Once upon a time, a man lived in a house that had no door. Everyone laughed at him. But he he didn't care, because it was easier to walk in and out of the house with no door so in his mind, he saved time and money.
    In the winter, though the house became very cold because it had no door. So he turned the heating up full to keep the house warm. He consumed vast amounts of electrical energy and polluted the planet. Everyone complained, but he didn't care. He could do what he wants with his money
    But the complaints grew so loud, that the government paid a shed load of money to experts to see what they could do to reduce the pollution from the vast amount of energy the man was wasting. After year's of research, the clever experts invented an 'air curtain' for the door. This way he could still walk in and out as he liked with wasting time with a door, and it would reduce the energy he was using. Every one clapped. What a great idea. Then the experts said lets see just how much energy we have saved with this idea. So the government paid them another shed load of money to investigate. After much research time, and funding, they were delighted to announce that the man could save 50% of his energy cost if he used these air curtains. What fantastic news every one cried, the man is happy, the experts are happy, the government are happy, and the pollution was reduced.
    The man who lived across the house was left scratching his head in wonder. His house had a door. His house had always had a door and his energy bills were much much lower. But no one was praising him, or giving him loads of money. So, he took his door off too, and the pollution from the extra energy he was using grew and grew. So the problem was worse, but everyone said it was better.
    Of course, this is a silly fairy tale and would never happen in real life. We only tell tales like this to make people laugh and learn a lesson, not to follow exactly.
