2. The standards for minimum room volume are as follows.
(1) No partition (shaded portion)
(2) When there is an effective opening with the adjacent room
for ventilation of leaking refrigerant gas (opening without
a door, or an opening 0.15% or larger than the respective
floor spaces at the top or bottom of the door).
(3) If an indoor unit is installed in each partitioned room and
the refrigerant tubing is interconnected, the smallest room
of course becomes the object. But when mechanical
ventilation is installed interlocked with a gas leakage
detector in the smallest room where the density limit is
exceeded, the volume of the next smallest room becomes
the object.

The minimum indoor floor space compared with the
amount of refrigerant is roughly as follows: (When the
ceiling is 2.7 m high)

Check of Density Limit
The room in which the air conditioner is to be installed
requires a design that in the event of refrigerant gas
leaking out, its density will not exceed a set limit.
The refrigerant (R410A), which is used in the air conditioner,
is safe, without the toxicity or combustibility of ammonia, and
is not restricted by laws imposed to protect the ozone layer.
However, since it contains more than air, it poses the risk of
suffocation if its density should rise excessively. Suffocation
from leakage of refrigerant is almost non-existent. With the
recent increase in the number of high density buildings,
however, the installation of multi air conditioner systems is
on the increase because of the need for effective use of floor
space, individual control, and energy conservation by curtailing
heat and carrying power, etc.
Most importantly, the multi air conditioner system is able
to replenish a large amount of refrigerant compared to
conventional individual air conditioners. If a single unit of the
multi air conditioner system is to be installed in a small room,
select a suitable model and installation procedure so that if the
refrigerant accidentally leaks out, its density does not reach the
limit (and in the event of an emergency, measures can be made
before injury can occur).
In a room where the density may exceed the limit, create an
opening with adjacent rooms, or install mechanical ventilation
combined with a gas leak detection device. The density is as
given below.
Total amount of refrigerant (k
g
)
Min. volume of the indoor unit installed room (m

)

/m

)
The density limit of refrigerant which is used in multi air
conditioners is 0.3 k
g
/m
3
(ISO 5149).
NOTE
1.
If there are 2 or more refrigerating systems in a single
refrigerating device, the amount of refrigerant should be as
charged in each independent device.
For the amount of charge in this example:
The possible amount of leaked refrigerant gas in rooms A,
B and C is 10 k
g
.
The possible amount of leaked refrigerant gas in rooms D,
E and F is 15 k
g
.
