Case Studies - Cooling Retail Premises at Decathlan
The Decathlon store at Stockport was refurbished in 2009. The existing refrigeration based air handlers provided only 100kW of cooling and in store temperatures reaching 40C were experienced during hot periods. An independent report commissioned by the store prior to refurbishment recommended at least 400kW of cooling. An analysis showed the comparison between EcoCooling and refrigeration.
| EcoCooling | Refrigeration | |
|---|---|---|
| CAPITAL | £20.00/m² | £62.50/m² |
| OPERATING | £0.20/m² | £3.00/m² |
| ELECTRICITY SUPPLY | 1x30A | 3x100A |
A total of 12 EcoCoolers together with extract fans were fitted to the store. The EcoCoolers and extract fans are thermostatically controlled in four zones. Down discharge EcoCoolers distribute air to 8 way plenum chambers positioned above the lighting level.
The performance of the cooling system was monitored during a warm period in July 2009. It can be seen from the graph below that the store temperature never exceed 24°C.
