When using a halide torch detector, under what condition will it detect system leaks?

• A. Only if the refrigerant contains chlorine.
• B. When the system temperature is above freezing.
• C. If it is tested during the day.
• D. When used alongside other leak-detection methods.

Answer: (A)

A halide torch detector is designed to identify the presence of halogenated refrigerants, which typically contain chlorine, bromine, or fluorine. When the halide torch comes into contact with these halogenated substances, it will produce a color change, indicating the presence of a leak. Thus, the detector is specifically sensitive to refrigerants that contain chlorine or other halogens, meaning that for effective leak detection, the refrigerant must contain these elements. The other conditions mentioned do not necessarily influence the performance of a halide torch detector. For instance, while the system temperature being above freezing may allow for liquid refrigerant to be present, it isn't a requirement for the halide torch to function. Similarly, daylight conditions or the use of other leak-detection methods do not directly enhance the sensitivity or operation of the halide torch detector itself; it is designed to detect the presence of halogens regardless of external conditions. Therefore, the presence of chlorine in the refrigerant is the crucial factor for the effective detection of system leaks using a halide torch.
