The space considered shall be any space
which contains refrigerant-containing parts or
into which refrigerant could be released.
The room area (A) of the smallest, enclosed,
occupied space shall be used in the
determination of the refrigerant quantity limits.
The maximum refrigerant charge is related to
types of the indoor units, which have different
installation heights
.
The lowest maximum allowable charge of all
rooms shall be used.
1.3.1.4 Refrigerant charge and room area
limitations (strategy 2)
The system also has a maximum design
refrigerant charge limit of 12 kg, which cannot
be exceeded under any circumstances.
The maximum refrigerant limit described above
applies to unventilated areas. For adding
additional measures, such as areas with
mechanical ventilation, please refer to
applicable legislation for the maximum
refrigerant limit.
Determine the charge limit for the refrigerating system
as the smaller of:
1) The maximum refrigerant charge (Mmax) in the
system from
the above room area limitations
.
2) The maximum refrigerant charge (Mmax) with
additional measures, such as areas with mechanical
ventilation.
3) 12 kg from the limit of the application.
Table 1-1
In IEC 60335-2-40, R32 refrigerant is classified as
class A2L, which is mildly flammable. And the system
meets the requirements of enhanced tightness
refrigerating systems. Therefore, R32 refrigerant is
suitable for systems needing additional refrigerant
charge and which will limit room area strategy.
Similarly, the total amount of refrigerant in the system
shall be less than or equal to the maximum refrigerant
charge. The maximum refrigerant charge depends on
the space of the rooms being served by the system.
As shown above:
1) Curve (a) is refrigerant charge limitation for the indoor
unit installation height between 1.8 m and 2.2 m.
2) Curve (b) is refrigerant charge limitation for the indoor
unit installation height not less than 2.2 m.
