10 ENVIRONMENT-FRIENDLY ALTERNATIVE REFRIGERANT R410A
ENGLISH
CAUTION
!
• The wall thickness of the piping should comply with the relevant local and national
regulations for the designed pressure 3.8 MPa
• Since R410A is a mixed refrigerant, the required additional refrigerant must be charged in
its liquid state.
If the refrigerant is charged in its gaseous state, its composition changes and the system
will not work properly.
• Do not place the refrigerant container under the direct rays of the sun to prevent it from
exploding.
• For high-pressure refrigerant, any unapproved pipe must not be used.
• Do not heat pipes more than necessary to prevent them from softening.
• Be careful not to install wrongly to minimize economic loss because it is expensive in
comparison with R22.
The refrigerant R410A has the property of higher operating pressure in comparison with R22.
Therefore, all materials have the characteristics of higher resisting pressure than R22 ones and
this characteristic should be also considered during the installation.
R410A is an azeotrope of R32 and R125 mixed at 50:50, so the ozone depletion potential (ODP)
of R410A is 0. These days the developed countries have approved it as the environment-friendly
refrigerant and encouraged to use it widely to prevent environment pollution.
