Can refrigerants be mixed in recovery cylinders?

Refrigerants should not be mixed in recovery cylinders because mixing different types of refrigerants can create a number of issues that compromise safety and efficiency. Each refrigerant has specific properties, including pressure, temperature ranges, and chemical composition. When refrigerants are mixed, these properties can change unpredictably, leading to inaccurate readings and the potential for hazardous situations.

Additionally, if a mixed refrigerant needs to be disposed of or reclaimed, the process becomes complicated since recovery facilities often require specific types of refrigerants to be collected separately. This makes the recycling and reclamation processes more difficult and can lead to non-compliance with environmental regulations.

Proper handling and adherence to regulations are crucial in HVAC practices, and ensuring that only one type of refrigerant is used in a recovery cylinder guarantees compliance with the EPA’s guidelines and promotes safer operational practices within the industry.
