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 piping is interconnected, the smallest
room of course becomes the object. But when a 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.
