Abbey Foods
The project included the installation of a fridge monitoring and control system to
enable a higher level of temperature control of a bank of display refrigeration units
installed in the Abbey Food Centre.
The existing refrigeration unit controls ensure the refrigerators operate within set temperature bands but these bands are usually wider than required under food safety regulations in order to ensure safe operation. The Food Centre with 40 refrigerators, installed this new control system which overrides the existing individual controls systems and thus maintains the fridge operation within a narrower band and this reduces the cycling and energy load and hence energy use by the refrigerators.
The average daily consumption was 378.2 kWh/day over this baseline monitoring period. With Smart Energy Controls, the average consumption over this monitoring period was 306.27kWh /day. The savings per day was 71.93kWh and this would equate to 26254 kWh of delivered electrical energy savings over one year.
Each of the 40 fridges have new controls enabled and the system fully complies with the HACCP (Hazard Analysis & Critical Control Point) which covers the procedures companies must put in place to ensure the food they sell/produce is properly stored and hence safe for human consumption.
These procedures make up the food safety management system based on the principles of HACCP and include fridge temperature measurements take at least twice daily, this system provide real time monitoring and therefore satisfies the HACCP standard.
