• For intermediate
H
values, the value that corresponds to the lower
H
value from the table considered.
Example:
For
H
=
1.25 m, the value that corresponds to “
H
=
1.20 m” is considered
.
• For intermediate
m
c
values, the value that corresponds to the higher
m
c
value from the table is considered.
Example:
If
m
c
= 1.85 kg, the value that corresponds to “
m
c
= 1.86 kg” is
considered.
• Systems with total refrigerant charge lower than 1.84 kg are not
subjected to any room area requirements.
• Charges above 2.30 kg are not allowed in the unit.
