CO2 COLD ROOMS

At Bernad Refrigeración we carry out projects of cooling rooms with ecological refrigerants such as carbon dioxide. We have wide experience in the design, installation and maintenance of all types of cooling installations. That is why we can guarantee our customers the maximum reliability.

 

Although it may seem like something new in the field of industrial cooling, it has been implemented since the mid-nineteenth century, acquiring in recent years greater notoriety in the refrigeration sector due to the increase in the rates of fluorinated gases and its status as a natural refrigerant.

The CO2 refrigerant, also known as R744 gas is a natural refrigerant that you can find in the natural environment as a gas and can modify its state by varying its pressure and temperature. It is not flammable, nor toxic and can work under very high gas pressures.
CO2 cooling is therefore an excellent alternative as a secondary refrigerant and in cascade installations too. It also does not damage the ozone layer and reduces the climate impact.
The CO2 refrigerant is used in small and medium freezing installations and in refrigeration facilities such as:

fishmongers, butchers, supermarkets, …

Carbon dioxide can be used in industrial facilities as a refrigerant gas in two phases: subcritical and transcritical.

subcrítica y transcrítica.

SUBCRITICAL PHASE

In the subcritical phase the CO2 evaporates and absorbs heat, then it get compressed and condensed and goes into a liquid state when it loses the heat. It works in a similar way to other refrigerant gases.

TRANSCRITICAL PHASE

In the transcritical phase, which is the most common in industrial cooling, CO2 does not condense and therefore does not change its gaseous state, that is, very high pressures are produced.

If you want a refrigeration installation with CO2 do not hesitate to contact us.
