Date Mar. 7, 1996A method of introducing a leak detection dye into a closed refrigeration system through circulation of the refrigerant. A predetermined amount of the leak detection dye, which is soluble in the refrigerant and the system lubricant, is installed in a component of the refrigeration system, such as in a desiccant bag placed in a dehydrator. The leak detection dye may come in various forms including as a leak detection additive having the leak detection dye implanted on and absorbed into a host swatch of a substrate material, as a powder, as a solid pellet of powdered dye concentrate and inert ingredients, or as a slurry. The refrigeration system is assembled, charged and operated, by which the refrigerant and system lubricant flowing through the component, such as a desiccant bag in the dehydrator, and mixes the dye with the refrigerant and system lubricant.
