Are open refrigerated cases costing you more than you think?
Open Refrigerated Display Case
✗ Poor energy efficiency
✗ Can conflict with store heating/AC Cold isles impact customer comfort
✗ Higher capital cost for plant
✓ Lower case capital cost
✗ Higher running costs
Refrigerated Display Case with doors
✓ ~ 60% energy efficiency improvement
✓ Improved customer comfort
✓ Extends produce shelf life
✗ Reduced plant cost (smaller size) Higher case capital cost
✓ Eligible for State rebate schemes
Buying new high efficiency refrigerated cases with doors or retrofitting doors on to existing cases can substantially reduce electricity costs. But both options require an initial capital outlay.
Help is at Hand – State Government energy efficiency rebates
CASE STUDY: Ritchies IGA refrigeration upgrade project
14 stores upgraded to deliver a 20.2% saving on total store electricity usage with an average payback on the investment of 18 months (VEU rebate inclusive).
Throughout 2019 -2021, RitchiesStores conducted a series of upgrades to the refrigeration in their VIC stores. This included enhancements to their medium temperature refrigerated display cases including:
✓ Door retrofit
✓ Fluorescent tube replacement with LED tubes
✓ Case fans upgraded to more efficient EC fans
✓ Controls upgrade to manage reduced refrigeration load. This included VSD on the lead compressor and unloaders on the lag compressors.
The energy savings were calculated via the Measurement & Verification method and the
rebate claimed through the VEU program
