By their nature some commercial refrigerators are just not that good for the size of your electricity bill but making a few sensible changes can lead to a 30% energy saving.
If you are looking to purchase new refrigeration consider what climate class your chiller or freezer is as this is an indication of how it will perform in differing ambient conditions. Also look at cabinet insulation thickness and whether a single, double or triple glazed display door.
For equipment already owned there are a number of practical steps that will help.
Location, location, location - for items such as sealed cabinets placing in direct sunlight or in the hottest part of a busy kitchen will mean the compressor having to work harder and use more energy.
Open fronted items such as display freezers if multidecks will be affected by this too but will also suffer from being placed in a drafty location.
Don't cram - most modern cabinet chillers and freezers require air circulation within the cabinet so overstocking can block this and affect the internal airflow causing the compressor to work too hard and may affect food temperatures and lead to waste.
Give me some air - as with internal air flow the chiller also need ventilation space to the sides and rear. If spacers are provided use them. Refrigerators need to radiate heat away from the condenser to operate correctly and be energy efficient.
Shut that door! - maybe obvious but the simplest and most often overlooked. Fit a nightblind to a multideck, a plastic curtain to cold rooms and other than when loading never prop open.
Service please - considering the inconvenience of a machine failure,which always happens at 7pm on a Friday, there are also the obvious health risks associated with incorrect food storage temperatures. A regular service by a competent engineer won't stop this but certainly reduces the chances of it happening.
Many customers will ignore this because their machine is still under warranty - your car may have a long warranty but receives a yearly service and an MOT as well so why not your expensive catering equipment?
