Carbon Trust launches refrigeration efficiency guide

The Carbon Trust’s new refrigeration guide claims to cut energy bills by 20 per cent with little or no investment

A new Carbon Trust guide, launched sets out easy, no or low cost steps that businesses can take to cut their refrigeration energy bills by up to 20 per cent.

The guide, Refrigeration Systems, includes a range of useful tips and advice including:

  • Refrigerated display cabinets: Buy high-efficiency cabinets which are listed under the Enhanced Capital Allowance (ECA) scheme - these can use 30 per cent less energy than a non-listed cabinet.
  • Cold rooms: Open doors can cost you £6 per hour for freezers - use an air-tight store with good door management, lighting and defrost control. 
  • Heat recovery: Recovering the heat emitted by refrigeration equipment can help to reduce boiler energy consumption by up to 30% - fit your new refrigeration system with an energy saving ‘desuperheater’.
  • Chillers: Use a chiller engineered for UK temperatures, with good part-load capacity and efficiency and you could save as much as £25,000 a year for a typical 800kW process chiller.

Richard Rugg, Director of Delivery Services at the Carbon Trust, said: “Any business seeking to cut its costs should be looking at its energy bills and for many companies refrigeration accounts for a large part of those energy costs.  Savings of up to 20 per cent are possible with simple no and low cost steps.  If your business uses refrigeration, it’s an opportunity that’s too good to miss.”

By investing £4,700 in a new condenser, County Antrim Dairy saved £3,200 in annual energy costs meaning that the costs were regained in less than 18 months.  When Evron Foods, a cold store operator in Craigavon, reviewed its refrigeration control systems it discovered that upgrading to defrost-on-demand technology would save £15,000 per year in energy costs and payback would take just one year.

Carbon Trust is calling on businesses to cut their energy bills by checking their refrigeration systems and is running a free webinar to help on 20 July. To take part and to view the guide, go to: www.carbontrust.co.uk/expertinenergy.
