Final answer:
Different refrigerants must be recovered into separate cylinders to avoid contamination, ensure proper disposal or recycling, and maintain safety standards.
Step-by-step explanation:
When dealing with the recovery of refrigerants from small systems, such as those in refrigerators or air conditioners, it is important to ensure that different refrigerants are not mixed in the same cylinder. Each type of refrigerant must be recovered into its own separate cylinder. This practice prevents contamination and ensures that the refrigerant can be recycled or disposed of properly. Mixing different refrigerants can also create safety hazards and may affect the performance of recovery equipment.
In a refrigeration system, multiple refrigerants should not be recovered in the same cylinder. This is because refrigerants have different properties and using different refrigerants in the same cylinder can lead to contamination and affect the performance of the system.
Each refrigeration system is designed to work with a specific refrigerant, and it is important to use only that refrigerant to ensure proper functioning and efficiency.
