Airedale International has recently helped frozen food retailer Iceland reduce its building energy costs by £6,000 per store each year through the introduction of its ACIS control system.
Initially introduced in 50 stores undergoing a major upgrade programme, Iceland took the decision to roll out ACIS across all 800+ of its stores after claimed significant savings.
In the stores where the ACIS controls system was installed, but no changes to plant were made, Iceland was able to compare and evidence energy draw before and after installation.
As a result of the implementation which is said allows the retailer tighter, more intelligent levels of control, coupled with free-cooling and part-load efficiencies during off-peak and non-trading hours, Iceland has reduced its energy costs by 10 per cent, with an expected pay-back period on the investment of two years or fewer.
Iceland required a standardised control system that could be integrated into all of the retailer’s stores for both new and existing cooling plant from Airedale and for retrofitting to other manufacturers’ equipment.
The system allows Iceland to intelligently manage heating, ventilation, air conditioning and refrigeration (HVACR) and other building services across multiple sites through a single central system and also makes managing spares and service simpler.
The sophisticated software links the programmable controller to key components within the cooling system, allowing units to be optimised for increased energy efficiency.
The controller had to be pre-programmable for a standard store and configurable on site, with selectable install parameters, saving significant installation costs.
Graham Ireland, Project Manager, Iceland said: “Airedale’s ACIS system is flexible ensuring, as individual store criteria vary, Airedale accommodates this by adapting the software. We can add in multiple time functions and know instantly, by checking the easy-to-read display, exactly what the controller is doing.
As the controller is standardised and uses one type of software, the system enables information to be centralised, which allows functionality to be easily monitored and evaluated. This streamlines the management process and simplifies the procedure for service contractors.”
