Check Of Density Limit - Panasonic Inverter R32 Series Technical Data & Service Manual

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
The minimum indoor floor space compared with the amount of refrigerant is roughly as follows:
