Technician A says that a refrigerant identifier is used to identify the amount of impurities in a sample of refrigerant. Technician B says that a refrigerant identifier will determine whether a sample of refrigerant is R-134a or R-12 and is better than 98% pure. Which technician is correct?<\/p>\n\n\n\n
A. Technician A is correct.<\/p>\n\n\n\n
B. Technician B is correct.<\/p>\n\n\n\n
C. Both technicians A and B are correct.<\/p>\n\n\n\n
D. Neither technician A nor B is correct.<\/p>\n\n\n\n
The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n The correct answer is C. Both technicians A and B are correct.<\/strong><\/p>\n\n\n\n Explanation:<\/strong><\/p>\n\n\n\n A refrigerant identifier is a crucial tool in HVAC (Heating, Ventilation, and Air Conditioning) systems for determining the type and purity of refrigerant present in a system.<\/p>\n\n\n\n Technician A’s Statement:<\/strong><\/p>\n\n\n\n Technician A asserts that a refrigerant identifier is used to identify the amount of impurities in a sample of refrigerant. This is accurate. Refrigerant identifiers analyze the refrigerant sample to detect contaminants such as moisture, oil, and non-condensable gases. This analysis ensures that the refrigerant meets the required purity standards for optimal system performance. For instance, SAE J2099 specifies that recycled R-134a refrigerant should not exceed 50 parts per million (ppm) of moisture, 500 ppm of lubricant, and 150 ppm of non-condensable gases by weight.<\/p>\n\n\n\n Technician B’s Statement:<\/strong><\/p>\n\n\n\n Technician B claims that a refrigerant identifier will determine whether a sample of refrigerant is R-134a or R-12 and is better than 98% pure. This is also correct. Refrigerant identifiers can distinguish between different types of refrigerants, such as R-134a and R-12, by analyzing the chemical composition of the sample. Additionally, these devices can assess the purity level of the refrigerant. A refrigerant with a purity level above 98% is generally considered suitable for reuse in HVAC systems, as higher purity levels contribute to better system efficiency and longevity.<\/p>\n\n\n\n In summary, refrigerant identifiers serve dual purposes: they identify the type of refrigerant present and assess its purity by detecting impurities. Both Technician A and Technician B provide accurate descriptions of the functions of a refrigerant identifier.<\/p>\n","protected":false},"excerpt":{"rendered":" Technician A says that a refrigerant identifier is used to identify the amount of impurities in a sample of refrigerant.
