Each separate piece of equipment will have its own equipment charge. It used to be the number of kilograms of gas in the system that was important for deciding the actions required for servicing and maintenance of a refrigeration or air conditioning system.
This has changed and it is now a measure of the effect the F-gases in the system could have on the atmosphere that is important. This is calculated by working out the quantity of CO2 that would have to be released to have the same warming effect on the atmosphere as the contents of the system.
This is known as the CO2 equivalent of the F-gas.
Different F-gases have different global warming potential. This relates to its ability to absorb energy and add to the warming of the atmosphere. Two pieces of refrigeration equipment that have a similar capacity for refrigerant can contain different F-gases. If released, the impact on the atmosphere could be significantly different.
The charge is calculated by multiplying the number of kilograms of F-gas by the global warming potential of the specific gas in the system.
