Answer :
Final answer:
The fluorescent leak detection system is mainly used to detect refrigerant leaks in refrigeration systems. While it can be theoretically extended to other types of leaks, the primary application is in refrigeration. Therefore, the correct option would be A.
Explanation:
Fluorescent Leak Detection System
A fluorescent leak detection system is a tool mainly used in various industrial applications to identify leaks in systems that use gases or fluids. The system works by adding a fluorescent dye to the fluid or gas in the system, which can be illuminated with a UV light to reveal leaks.
Options Analysis
- A. detects refrigerant leaks in a refrigeration system. This is correct, as fluorescent dyes are commonly used in refrigeration to locate refrigerant leaks.
- B. detects water vapor leaks in a hot water boiler. This is generally not applicable, as water vapor does not typically require fluorescent leak detection. Standard methods such as pressure tests are used for boilers.
- C. detects nitrogen leaks at the pressure regulator. This is less common, as nitrogen is an inert gas and might not be detected effectively with fluorescent dyes.
Based on this analysis, option D. All of the above is incorrect. The most relevant application is detecting refrigerant leaks in refrigeration systems.
