A disposable cylinder may be used to recover refrigerant when the refrigerant type is non-flammable, non-toxic, and the cylinder is specifically approved for refrigerant recovery. Additionally, the cylinder must be empty, and the recovery process should comply with local regulations and environmental guidelines. It's important to ensure the cylinder is properly labeled and that the recovery is performed by a certified technician to avoid safety hazards.
Use a vacuum pump that pulls it into a tank.
Refrigerant pressure in a graduated cylinder is maintained by adjusting the flow of the refrigerant entering the cylinder. A valve connected to the cylinder regulates the flow of refrigerant, allowing the pressure inside the cylinder to be controlled. Monitoring and adjusting the valve ensures that the desired pressure level is maintained during the experiment.
It is maintained through the use of a compressor in a graduated cylinder
No, disposable tanks are not suitable for storing recycled refrigerant. They are designed for single use and lack the necessary safety features and pressure ratings for long-term storage of refrigerants. Recycled refrigerant should be stored in proper refillable cylinders that comply with safety regulations. Using appropriate equipment ensures safe handling and prevents potential hazards.
Use R-134
R134a

Because it's the only way to recover it. You recover from the high pressure side, and charge it on the low pressure side.
When filling a charging cylinder, the vented refrigerant at the top should be managed carefully to avoid releasing it into the atmosphere, as this can be harmful and is often illegal. It's important to ensure the cylinder is upright to allow any excess refrigerant to escape through the vapor vent. Additionally, you can use a recovery machine to capture any vented refrigerant, ensuring compliance with environmental regulations. Always follow proper safety protocols and guidelines during this process.
The safest method to warm a refrigerant cylinder is to use warm water. Submerging the cylinder in a tub of warm (not hot) water helps increase the pressure inside the cylinder without risking damage or release of refrigerant. Avoid using direct heat sources like open flames or heating pads, as these can cause rapid pressure changes or create safety hazards. Always ensure proper ventilation and follow safety guidelines when handling refrigerants.
