Guidance for End Users


Guidance for users of refrigerating equipment in the food and drink manufacturing industries

A series of guidance notes have been produced as the result of a Carbon Trust Funded project led by the Food and Drink Federation and partners including the Cold Storage and Distribution Federation, British Beer and Pub Association, Diary UK and the Institute of Refrigeration.

The notes below are all available as free downloads and were written by refrigeration and energy specialists based on site inspections carried out in 2006 and 2007.

  • Appointing and Managing Refrigeration Contractors (T1) - Are you responsible for appointing contractors to carry out the service and maintenance of your refrigeration equipment?  This guide will help you to maximise plant efficiency (and save money on electricity costs) and reduce costly equipment failure. It outlines different types of maintenance contract as well as giving advice on how to select the right contractor for you.


  • Purchase of Efficient Refrigeration Plant  (T2) - Are you considering replacing existing equipment or investing in new plant? This guide will help you to select new equipment that leads to reduced energy costs, minimised environmental impact, increased reliability and reduced maintenance costs.  The greatest opportunity to maximise refrigerant plant operational efficiency is at the specification and purchasing point. 


  • Operational Efficiency Improvements for Refrigeration Systems (T3) - Do you want to minimise your energy spend by operating plant more efficiently?  This guide will help you to check the performance of refrigerating systems so that you can make savings by operating it more efficiency as well as correcting energy wasting faults


  • R22 Phase Out and F Gas Regulations - Are you concerned about legal restrictions on the refrigerants used in existing and new systems?  This guide will help you to comply with the operators' obligations under EU regulations on ozone depleting HCFC refrigerants such as R22 and global warming refrigerants such as HFC R134a or R404a.


  • Results of Site Investigations - This guide will help you improve the performance of your refrigeration equipment based on investigations carried out at 30 sites.  Make savings by reducing heat loads and by carrying out cooling at the appropriate temperature.  Making savings by improving the condenser system and, in particular, by reducing head pressure.  Making savings by improving part load performance.  Making savings by reducing power consumed by auxiliary pumps and fans.

The Institute of Refrigeration hasdeveloped a System Efficiency Index to help evaluate the relative efficiency of different system options and designs. This free tool was developed with support of the Carbon Trust and you can download a copy here.
