Industrial Refrigeration Service Ltd found Energy surveillance was the first step in assessing what energy savings could be made at one of our customer’s sites, with the ‘the Basement’ identified as the first area to be scrutinised.
IRS have developed a simple, yet comprehensive means of
measuring temperatures and electrical energy usage, which
clearly demonstrates what the current situation is and a
- Energy efficiency review of basement area
- Study highlighted many areas could be improved
- Utilisation of Fresh Air (Free Cooling)
- Ensure appropriate areas are insulated to conserve energy
- Thousands of pounds saved from day one
There are five main areas in the Basement including the Plantroom (15% of the area), Stockroom (70% of the area), Electrical switch/panel room (5% of the area), Sub station (5% of the area) and the stairwell (5% of area).
Although the initial review of energy efficiency was to focus on
the stockroom, which is currently controlled at 12.5°c by
means of two refrigeration systems, it was clear right from the
start that all areas could benefit from a detailed review.
It is estimated that total savings in the first year to be nearly £16,000 where investment is needed to
initiate energy efficiency, with annual total savings estimated to be nearly £28,000. This does not include
the potential saving on breakdown of refrigeration equipment due to the vastly reduced running hours.
To retrieve the current conditions, temperature and electrical current probes were attached to each refrigeration system and temperature probes within the store and on the outside wall. Surprisingly the survey revealed that the heat load and refrigeration capacity of one of the two systems appears completely matched within the period measured.
