Energy reduction

A client with over 800 stores within their estate was keen to explore what ways they could reduce energy consumption amongst their integral refrigeration fleet. Alongside this, they wanted to better understand their energy usage and what they could do to start reducing it. Drinks refrigeration were targeted for this study, but HVAC, Bakeries, and Lighting are all business-critical functions that require substantial energy usage and can be analysed in further studies with LoweConex.

The Solution

The team at LoweConex implemented two energy consumption countermeasures on a PureCold 60 open fronted cabinet loaded with bottles of water.

Product probes were also used to record the temperature of the water throughout and this information is available upon request.

Countermeasure 1

Increase Drinks Cabinet Set-Point to an Industry Standard.

The below table shows the current drink cabinet temperature as recorded by LoweConex and a recommended adjustment in that set-point in-line with industry standard.
Using certified energy measurement equipment, LoweConex can accurately predict the below saving in energy consumption and costs.

LoweConex IoT Two-Way communication can be used to remotely apply this set-
point change automatically & estate wide.

Countermeasure 2

Combined Set-point Change & Overnight Shut Off

A combination of countermeasure 1 and a 12-hour compressor shut-down (8pm-8am) will generate an additional reduction of £79.57 in energy cost per cabinet per year.

LoweConex IoT Two-way communication can be used to remote apply this set- point change and timed shutdown automatically.

The Outcome

The study has shown that if this retailer applied both countermeasures to their BWS/Drinks cabinets estate-wide a 24hr energy reduction of 4.6kw and a yearly cost saving of £266.45 per cabinet can easily be achieved with no effect on product.
