9. Precautions on Refrigerant Leakage
This air conditioner (A/C) adopts innocuous and nonflammable refrigerant. The locating room of the A/C
should big enough that any refrigerant leakage is unable to reach critical thickness. So certain essential action
can be taken on time.
Refrigerant critical thickness: 0.44[kg/m] for R410A.
Confirm the critical thickness through follow steps, and take necessary actions.
1.
Calculate the sum of the charge volume (A[kg]) Total Refrigerant volume of 10HP=factory refrigerant
superaddition
2.
Calculate the indoor cubage (B[m]) (as the minimum cubage.
3.
Calculate the refrigerant thickness
Counter measure against over high thickness
1.
Install mechanical ventilator to reduce the refrigerant thickness under critical level. (ventilate regularly)
2.
Install leak alarm facility related to mechanical ventilator if you can not regularly ventilate.
NOTE
Please press “constraint cool” button to carry out refrigerant recycling process. Keep the low pressure above 0.2MPa; otherwise
compressor may be burnt out.
