What can be used for leak detection with high-pressure refrigerants?

Using soap bubbles for leak detection with high-pressure refrigerants is an effective method because it enables technicians to visually identify leaks quickly. When soap bubbles are applied to potential leak points, the soap solution will form bubbles when gas escapes. This offers a clear and immediate visual indication of where a leak is present, which is especially important when working with high-pressure systems where the refrigerant can escape rapidly.

In the context of high-pressure refrigerants, other options might not provide the same level of visibility or reliability. While thermal imaging can indicate temperature changes around leaks, it does not directly show the presence of the refrigerant. Pressure gauges are useful for assessing system performance but do not pinpoint specific leak locations. Ultrasonic detectors can identify sound waves produced by leaks, but this method requires a higher level of expertise to interpret the sounds correctly. Thus, the simplicity and reliability of using soap bubbles make it a preferred choice for quickly detecting leaks in high-pressure refrigerant systems.
