Abstract: A system for detecting a gas leak in a generator includes a source of carbon dioxide gas, and a subsystem for introducing the carbon dioxide gas into the generator. An infrared imaging device is adapted to communicate with a notification device to display an image of at least a portion of the generator and the carbon dioxide gas. The infrared imaging device is a cooled detector and a filter with a spectral response between about 3 μm and about 5 μm. At least one of the detector and the filter is cooled to between about −80° C. and about −200° C. The gas leak will be indicated on the notification device.

Abstract: Compositions and related methods for detecting leaks in HVAC/R components such as furnaces, portable gas heaters, swimming pool heaters, air conditioners, heat pumps, refrigerators, freezers, and other closed loop vapor compression systems, as well as heat exchangers. These compositions provide more sensitive detection of leaks in inaccessible areas of furnaces using low ODP and non-flammable compounds classified as hydrofluorochloro-ethers (HFCE's), hydrobromochlorofluoro-alkenes (HBCFA's) hydrofluoro-ethers (HFE's), and halogenated compounds which are either alkanes, alcohols, diones, acetates, ketones (e.g., butanones, pentanones), esters (e.g., propanoates), anhydrides, cycloalkanes (cycloparaffins), cycloalkenes (cycloolefins), heterocyclics (e.g., furans), and aromatics.

Abstract: Disclosed herein are detectable refrigerant compositions, comprising from about 0.001 to about 5 weight percent tracer compositions, which are useful to identify leaking in a vapor compression refrigeration and/or air conditioning system. The presence of the tracers make the refrigerant compositions detectable by chemo/electro-active array, corona discharge, heated diode, electrochemical, photoionization, infrared, ultrasonic and electron capture detectors.
