3 CHAP PAGE ITRE 3 19 Test refrigerant for contamination Refrigerants can be tested for water/oil contamination and acidity with a test kit. With the change to alternative refrigerants, in many cases, has come need for new lubricants. Where retrofit procedures call for the removal of mineral-based oil and replacement with ester lubricants, it is necessary to reduce the mineral lubricant to a minimal level. These test kits provide simple methods of determining the level of residual mineral oil in an ester lubricant mixture. Test oil contamination It is possible to test the oil in some systems for acidity. Acid in the oil indicates that burnout or partial burnout has taken place, and/or that there is moisture in the system, which can cause a burnout. To carry out an oil test it is necessary to remove a sample of oil from the compressor without undue release of refrigerant. The procedure for this will vary depending on the arrangement of shutoff valves and access to the oil available on the unit. For many hermetic compressors there will be neither shut off valves nor access. This image shows an example of a refrigerant testing kit. Refrigerant testing kit The refrigeration oil acid test kit is one-bottle (one step) test, and is the fastest way of determining if compressor oil is safe or acidic. If the test result in the mixture remaining purple, the oil is safe, whereas if it turns yellow, it is acidic. The ultra-sensitive colour change guarantees an accurate test. Checking of refrigerant cylinders Decanting refrigerants into service cylinders is a hazardous practice. It should always be carried out using the method prescribed by the refrigerant manufacturer. Special care should be taken: • Not to overfill the cylinder • Not to mix grades of refrigerant or put one grade in a cylinder moisture etc. • Recovery cylinders should have a specific indication depending on the country in order not to be confused with virgin refrigerant container TEST KIT labelled for another CHAPITRE 3 • To use only clean cylinders, free from contamination by oil, acid, PAGE 20 Cylinder with separate liquid and gas valves • To visually check each cylinder before use and make sure all cylinders are regularly pressure tested • Cylinders should have separate liquid and gas valves and be fitted with a pressure relief device, as shown in the diagram: Cylinder with separate liquid and gas valves Vapor Liquid Yellow Cutaway view Grey 77 Refrigerant ManagementPDF Image | Manual for Refrigeration Servicing Technicians
