Caution For Refrigerant Leak

(3) With partition and without opening which serve as passage of air to adjoining room

Calculate refrigerant concentration

■ In case the concentration exceeds the limit

When the concentration exceeds the limit, change original plan or take one of the countermeasures

shown below:

• Countermeasure 1

Provide opening for ventilation.

Provide 0.15% or more opening to floor space both above and below door, or provide opening without

door.

• Countermeasure 2

Provide gas leak alarm linked with mechanical ventilator.

Reducing the outside refrigerant qty.

Pay a special attention to the place, such as a basement, etc. where refrigerant can stay, since refrigerant is

heavier than air.

In case the result of calculation exceeds

the limiting concentration, perform the

same calculations by shifting to the

second smallest, and the third smallest

rooms until at last the result is below the

limiting concentration.
