The Leak Detection System of Air-Conditioning Pipeline Based on LabVIEW
Air conditioning refrigerant leakage is often in the course of one fault occurs, the event of leakage, in a very short period of time cooling system will be unable to function properly. In order to realize the reign of air pipelines leak detection, this article is brought forth new ideas that pipe leak detection of air conditioning is achieved by the stress wave technology and by programming in the development environment of LabVIEW. Experimental results show that this new method is quick, accurate and reliable to detect and to locate the leak source occurred, the system measures the absolute positioning error is less than 0.3% and the relative error is better than 1.5%.
