Selection method of refrigerant pipe
Refrigerant pipe of outdoor unit is same as (Table 1)
1+1.25+2+0.8+0.8=5.08 (Table 2)
2+1.25+1+0.8+0.8=5.85 (Table 2)
1.25+1+0.8+0.8=3.85 (Table 2)
1+0.8+0.8=2.6 (Table 2)
0.8+0.8=1.6 (Table 2)
0.8+0.8=1.6 (Table 2)
Refrigerant pipe of indoor unit is same as (Table 3)
