by locating at least one sensor within 30 horizontal feet of each potential leak source (one sensor located between 2 evaporators could cover them both if they are 60 feet apart). In large, open cold storage warehouse rooms where this results in more than 3 sensors in a room, distances can reasonably be relaxed to 50 horizontal feet from a potential leak source, with a minimum of 3 sensors ...

Leakage detection - detecting CO2 leakage into ammonia

Leakage detection - detecting CO2 leakage into ammonia Two different sensors are available for detecting leakage in CO2/ammonia cascade systems and they both react on the formation of ammonia carbamate which is a very corrosive salt that blocks the pipes and compressor. The sensor Detects a leakage quickly because the conductivity increases significantly when ammonia carbamate is formed. …

This paper presents a technique for the CO 2 leakage detection and location identification through acoustic sensing. The technique uses a pa ir of acoustic sensors, which are installed on two points of apipeline. When a CO 2 leakage occurs from the pipeline, the pressure at the leaking point will drop suddenly and the leakage source can produce fierce vortex flow with acoustic emission. The ...
