Cold rooms need to use better construction and insulation methods to avoid adverse energy consumption.
Grahame Keeping, GR Scott business development manager, who is currently involved in an EU project on the subject, said: “We constantly come across poor installation after being called out to rectify the problems left through substandard installation and equipment.”
“The trouble is that in many instances, retailers are forcing companies to fit cheap boxes. A lot of the reason for this is based on cost, with the pressure to stay competitive forcing installers to cut corners and use cheaper product.”
Mr Keeping is currently a contributor to the LOT1 consultation group, which is part of a preparatory study on refrigerating and freezing equipment for the forthcoming EC Ecodesign Directive.
Ecodesign aims to establish a framework under which manufacturers of energy using products, will, at design stage, be obliged to reduce the energy consumption and other environmental impacts throughout a product’s lifecycle.
“It surprises me that supermarkets win all these awards for the smaller stuff, but don’t keep an eye on obvious elements of refrigeration such as cold rooms.”
“Some suppliers and engineers are also cutting out key elements of construction that make up an efficient cold room, scrimping on the quality of insulation thickness, finish and door construction/seal.”
“A poorly installed/finished cold room can be significantly less efficient, leading to a dramatic increase in energy consumption.”
According to a study published in LOT1 the presence of sufficient insulation can reduce energy consumption by up to 40 per cent, compared with equipment with a standard thickness of insulation.
