2.2.1 Limits to the use – Minimum area of the conditioned space and maximum
refrigerant charge
Clause GG.9 of Annex GG within the standard IEC 60335-2-40:2018 (Household and similar electrical appliances -
Safety - Part 2-40: Particular requirements for electrical heat pumps, air-conditioners and dehumidiers) denes the
charge limits based on the total conditioned space area and the ventilation requirements for ducted appliances using
A2L refrigerants. For full details refer to the standard IEC 60335-2-40:2018.
The minimum total conditioned room area "TA

No zoning dampers shall be installed in the rooms considered to determine the minimum room area
unless these zoning dampers can be fully opened by the control signal of the rooftop in case of a leak
If the refrigerant charge is adjusted on the eld, the minimum area must be re-evaluated in order to be always above
the result obtained through the following formula:
where
- m
added
is the refrigerant charge added on the eld in kg.
The sum “m
c
+m
added
" must be lower than 79,8 kg for each circuit.
