This article analyzes the different brands Freon leaks from refrigeration unit medium and low productivity. Noted, that the main indicator of safety is destructive activity of the ozone layer. It should be noted that the degree of safety for the ozone layer, for example: R12 taken at 1.00, popular R22 has this coefficient 0.05, but new zeotrope R407C - 0,00. Also identifies the dangerous properties of freons, such as: a suffocating effect on humans (Freon can asphyxiating effect only when its content more than 30 % of the total volume of air and its accumulation in enclosed spaces, since it displaces the air, and the man begins to suffocate due to lack of oxygen); toxic effects by combustion (exposed to temperatures exceeding 400 В°C, a chemical reaction occurs with the formation of toxic phosgene and fluoride compounds and hydrogen chloride, which is irritating to the mucous membranes) [1]. The various ways and methods of detection Freon leak with simple and complex modern instruments are also considered. These include: the using of soap solutions, which are applied when an area of leakage is known with high degree of probability; method of immersing the object in the water that is used when the system is fairly compact; use halogen leak detectors, which are used only when working with chlorine containing refrigerants, electronic and ultrasonic leak detectors; dye penetration method, which stands on the site of a leak after a certain amount of time. The expediency and economic efficiency of the application and using various methods, techniques, and detection devices of different brands of CFCs in refrigeration plants is substantiated.
