3. Calculate refrigerant concentration from the results of step 1 and 2.
Total amount of refrigerant in refrigerant
system
Unit: kg
≤
Refrigerant concentration (R410A)
Unit: kg/m
3
Capacity of smallest room where indoor unit
is installed
Unit: m

When the result of calculation exceeds the limiting concentration, perform the same calculation
by shifting to second smallest, and the third smallest rooms until the final result is below the
limiting concentration.
1-2. Checking concentration limit - (09-3) - 1. Refrigerant leakage caution
