REFRIGERANT CHARGE FOR THE SET:
EXAMPLE:
To install a CSH 030 + CIH 030 set, with 22m refrigerant line length between the outdoor and indoor units,
the refrigerant charge must be calculated as follows:
1
.
TABLE 1 (p. 20) shows that for 22m of line length between the indoor unit and outdoor units, the line sizes are:
liquid 5/8” and gas 1 1/8”.
2
.
TABLE 2 (p. 20) shows, for line sizes of 5/8”-1 1/8”, the charge per meter of line is: 177 g/m x 22m = 3894 g.
3
.
TABLE 3.1 shows charge of refrigerant for a set with 0m line length is: 6900 g.
4
.
To determine the charge of the set:
Add the charge in the refrigerant lines + the charge in the indoor unit and outdoor refrigerant units.
Total charge for the set: 3894 + 6900 = 10794 g
Note: If the outdoor unit includes the factory pre-charged kit, only the weight of refrigerant per meter of line in TABLE 2
is taken into account.
