Refrigerant properties would be composed of substances which are needed in the cooling and refrigeration processes. There are more than 100 types of refrigerants which are used in numerous types of industries, including the harmful refrigerants in the form of HCFCs and CFCs. As these substances are very efficient in cooling, we dont want them in the atmosphere due to its adverse impacts.



There are four refrigerant properties that are considered in the design of a refrigeration, cooling, or air conditioning system. Cost effectiveness and operational efficiency are high on the list, along with low toxicity and flammability. Energy standards and tests which documents safety and efficiency levels are available for industry use.



Refrigerant properties are of particular concern to environmental government agencies worldwide because some of the chemical substances used in certain types of refrigerants lead to ozone depletion or have a high global warming potential. Clean Air Act, the Montreal Protocol and the Kyoto Treaty are the major global treaties regulating emissions from systems that use refrigerant gases.



Some of the ref where to buy michael kors purses rigerant properties which cause harmful effects to the environment include chlorofluorocarbons and hydrochlorofluorocarbons. The gases remain in the atmosphere for hundreds of years, thus depleting the ozone layer that protects the earth from the suns harmful rays. The greenhouse gases are also contributing to global warming, which will cause an adverse climate change if no action is taken.



There are various classes of refrigerant properties. Refrigerants with toxicity levels below 400ppm are Class B, while those without toxicity levels below or equal to 400ppm in volume are Class A. In addition, numerical designations, ranging from Class 1 to Class 3, indicate flame propagation, with Class 3 being refrigerants that are highly flammable.



Among the refrigerant properties being considered to replace chemicals that are harmful to the environment include ammonia, carbon dioxide, propane and HFC32. However, these alternatives bring additional conc where to buy michael kors purses erns. Ammonia is considered the preferred refrigerant because there are no global warming concerns. Since it is toxic and combustible, its use is best for certain controlled applications, such as commercial or large facility use.



While carbon dioxide has no safety concerns, the need to use more electricity would negate any global warming reduction. Propane, under consideration as an alternative in refrigerators, is risky because it is very combustible. HFC32 is a hydrochlorofluorocarbon that is efficient and has no global warming impact. However, due to the combustible characteristics of these refrigerant properties, safety measures are much needed.



Tracking where to buy michael kors purses and reporting of refrigerant properties are required under global government treaties to gain a better understanding of how extensive the use of harmful refrigerants are and to measure the amount of dangerous substances released into the air during a refrigerant leak. This will enable scientists to better formulate the extent and impact of global warming and ozone depletion in coming years and devise additional prevention methods.
