Checking procedure of limiting concentration
Check limiting concentration along following steps and take appropri-
ate measure depending on the situation.
Calculate amount of all the replenished refrigerant (kg) per each refrig-
erant system.
Calculate minimum room capacity
Calculate room capacity by regarding a portion as one room or the
smaller room.
- With partition and with opening
which serve as passage of air to
adjoining room
- Without partition
Limiting concentration is the limit of Freon gas concentration
where immediate measures can be taken without hurting human
body when refrigerant leaks in the air. The limiting concentration
shall be described in the unit of kg/m
3
(Freon gas weight per unit
air volume) for facilitating calculation.
Limiting concentration: 0.44kg/m

The installer and system specialist shall secure safety against leakage
according to local regulations or standards.
The following standards may be applicable if local regulations are not
available.
Introduction
Though the R410A refrigerant is harmless and incombustible itself ,
the room to equip the air conditioner should be large to such an extent
that the refrigerant gas will not exceed the limiting concentration even
if the refrigerant gas leaks in the room.
