To successfully reduce costs in the implementation of a CO2 system, either with the intention of replacing an HFC system or for new installations, it’s essential to start the project from a global approach before starting with the technical part and the specific conditions of the project.
The design of a transcritical CO2 system is a challenge even for a refrigeration expert. The correct implementation and quality of the equipment depends not only on the efficiency, but also on the safety and profitability of the production plant. When evaluating the feasibility of this system in a refrigeration project, it’s convenient to consider these 4 points.
Although the use of CO2 as refrigerant gas in industrial refrigeration systems is very old, lately we have witnessed an increase in its implementation due to current legislation to stop climate change. This has generated a large margin of opportunity in which the care of the environment goes hand in hand with the energy efficiency of companies, thanks to the use of natural refrigerants in the industry.
Trying to maintain the ideal temperature for your industrial processes will be very difficult, if not impossible, if you don’t consider adequate control of relative humidity. This relation is this simple: the amount of heat generated in an environment will be considerably affected by the amount of water present in the air.
For some years, natural refrigerants have been the medium used in large industrial refrigeration systems within the food and beverage industry for both production and storage. Due to growing concerns about the harmful effects that refrigerants can exert on the environment, natural refrigerants have undergone a new rebirth, especially the NH3 and CO2 used for industrial purposes with low temperatures.
