CHECK OF DENSITY LIMIT
The refrigerant (R32), which is used in the air conditioner, is a flammable refrigerant. So the requirements for installation space of
appliance are determined according to the refrigerant charge amount [m
c
] used in the appliance.
The minimum indoor floor space compared with the amount of refrigerant is roughly as follows:
0.0
2.0
4.0
6.0
8.0
10.0
12.0
14.0
16.0
18.0
20.0
