Pagina afdrukkenPrecautions for using R32 refrigerant
The basic installation work procedures are the same as the conventional refrigerant
(R22 or R410A). However, pay attention to the following points:
1. Transport of equipment containing flammable refrigerants
Compliance with the transport regulations
2. Marking of equipment using signs
Compliance with local regulations
3. Disposal of equipment using flammable refrigerants
Compliance with national regulations
4. Storage of equipment/appliances
The storage of equipment should be in accordance with the manufacturer's
instructions.
5. Storage of packed (unsold) equipment
Storage package protection should be constructed such that mechanical damage
to the equipment inside the package will not cause a leak of the refrigerant charge.
The maximum number of pieces of equipment permitted to be stored together
will be determined by local regulations.
6. Information on servicing
6-1 Checks to the area
Prior to beginning work on systems containing flammable refrigerants, safety checks
are necessary to ensure that the risk of ignition is minimized. For repair
to the refrigerating system, the following precautions shall be complied with prior
to conducting work on the system.
6-2 Work procedure
Work shall be undertaken under a controlled procedure to minimize the risk
of flammable gas or vapor being present while the work is being performed.
6-3 General work area
All maintenance staff and others working in the local area shall be instructed
on the nature of work being carried out. Work in confined spaces shall be avoided.
The area around the workspace shall be sectioned off. Ensure that the conditions
within the area have been made safe by control of flammable material.
6-4 Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to and during
work, to ensure the technician is aware of potentially flammable atmospheres.
Ensure that the leak detection equipment being used is suitable for use
with flammable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.
