Procedures of Charging Refrigerants

Scrap and Recovery

As a supplement to the general procedure, the following requirements need to be added:

- Make sure that there is no contamination among different refrigerants when using a refrigerant charging device.

The pipeline for charging refrigerants should be as short as possible to reduce the residual of refrigerants in it.

- Storage tanks should remain vertically up.

- Make sure the grounding solutions are already taken before the refrigeration system is charged with refrigerants.

1.Be familiar with the equipment and operation.

2.Disconnect power supply.

3.Before carrying out this process, you have to make sure:

• If necessary, mechanical equipment operation should facilitate the operation of the refrigerant tank.

• All personal protective equipment is effective and can be used correctly.

• The whole recovery process should be carried out under the guidance of qualified personnel.

•The recovering of equipment and storage tank should comply with the relevant national standards.

4. lf possible, the refrigerating system should be vacuumized.

5. If the vacuum state can’t be reached, you should extract the refrigerant in each part of the system from many

places.

11. The recovered refrigerants are not allowed to be injected into another system before being purified and tested.

Note: The identification should be made after the appliance is scrapped and refrigerants are evacuated. The

identification should contain the date and endorsement. Make sure the identification on the appliance can reflect

the flammable refrigerants contained in this appliance.

Recovery:

1. The clearance of refrigerants in the system is required when repairing or scrapping the appliance. It is

recommended to completely remove the refrigerant.

2. Only a special refrigerant tank can be used when loading the refrigerant into the storage tank. Make sure the

capacity of the tank is appropriate to the refrigerant injection quantity in the entire system. All tanks intended to

be used for the recovery of refrigerants should have a refrigerant identification (i.e. refrigerant recovery tank).

equipment, check if it is in a good condition and if it gets perfect maintenance. Check if II electrical components

are sealed to prevent the leakage of the refrigerant and the fire caused by it. If you have any question, please

consult the manufacturer.

4. Through blowing process, the system is charged into the anaerobic nitrogen to reach the working pressure

under the vacuum state, then the oxygen free nitrogen is emitted to the atmosphere, and in the end, vacuumize

the system. Repeat this process until all refrigerants in the system is cleared. After the final charging of the

anaerobic nitrogen, discharge the gas into the atmosphere pressure, and then the system can be welded. This

operation is necessary for welding the pipeline.
