The article presents the methodology for calculating the maximum refrigerant charge in refrigeration installations
depending on refrigerants flammability and toxicity. The methodology is taken from ISO 817: 2014 and EN 378-1:
2016. Examples of calculations and examples of technical solutions are also shown, thanks to which it is possible to
solve problems related to the design of multi-evaporator refrigeration installations by following the standards and
engineering practice.
