What is the climate class of a refrigerator and how does it affect its efficiency?

Commercial coolers and freezers are designed to operate under certain environmental (climatic) conditions. The climate category or class of a professional cooler or freezer, indicates the minimum and maximum limits of temperature and humidity, within which the device is made to be able to function properly.

Let’s look at a simple example why it is so important to choose a cooler with the right climate class?

Not all refrigerator appliances are suitable for all ambient temperatures range.

If a refrigerator operates under conditions for which it was not manufactured, it will consume much more energy to reach the required indoor temperature. Also the compressor, which is responsible for cooling the refrigerator will not be able to function properly, which will lead to a reduction in its service life.

It is clear that if we place a professional refrigerator that is made for an ambient temperature range of + 10 ° C to + 30 ° C in an area that has temperatures higher than 30 ° C or place it in a place where it is exposed to the sun it will not be able to render properly, will consume more energy and will not preserve food properly.

The following tables show the correlation between climate zones and temperature range for different categories of commercial coolers and freezers.
