Energy savings tips for cold rooms How to ensure energy efficiency in the daily use
1 INITIAL PLANNING OF THE COLD ROOM ACCORDING TO USAGE
NEEDS
During the planning phase of a cold room it is important to adapt wall
thickness, floor characteristics, choice of materials as wel as the layout
to the application and needs for daily use. A well-fitting refrigeration
unit and technology create perfect conditions for energy savings
during operation.

ENSURE PROPER CLOSING OF THE COLD ROOM DOORS
Do not keep doors open for a long time and do not wedge them to stay
open while picking of the goods. A well structured storage system can
help to minimise the stay inside the cold room and increase energy efficiency. A strip curtain can help to save energy during longer opening
of the door.
3 DO NOT STORE HOT GOODS
Cool down warm goods as much as possible before storing them in
the cold room. Warm goods influence the energy efficiency of the
storage room as they have a big impact on refrigeration temperature
inside.
4 REMEMBER STACKING HEIGHTS
When stacking goods in the cold room always remember to ensure a
undisturbed circulation of cold air for perfect cooling of in all corners
and height levels of the cold room. There are maximum stacking
heights to respect.
5 CORRECT STORAGE TEMPERATURES
Set storage temperatures according to the goods you are storing.
Required temperatures for various products you can find in relevant
directives and regulations. For different goods in one and the same
room, always choose the lowest temperature requirement of a product
category you store.
6 TEMPERATURE SETTINGS FOR COLD OR FREEZER ROOMS NOT
IN USE
Increase the temperature for a temporarily empty freezer room to
-5°C. Keeping the room temperature even for an empty freezer room
slightly under 0°C, you can save up to 35% of energy.
If a cold room will be empty in the medium or long-term you can turn
off the refrigeration supply to save energy.
7 ENERGY EFFICIENT LIGHTING OF A COLD ROOM
Use LED lights and turn off lights after leaving the cold room. LED
lights have the advantage of a high light supply and high energy efficiency and therefore a low heat emission at the same time. Consult
your Viessmann qualified supplier if a motion detector with time delay
could be useful according to your needs.
