16. 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:
1.22 3.501.80 3.88
