Hydrocarbons
Utilities are compounds that consist mainly of carbon and hydrogen. Utilities are methane, ethane, propane, CYCLOPROPANE, Bhutan, and cyclopentane. Although housing is highly flammable, they may offer benefits, as alternative refrigerants because they are inexpensive to produce and have zero ozone depletion potential (ODP)and very low global warming potential (GWP)and low toxicity. There are several types of HC families such as the following:
- Hydrobromofluorocarbons (HBFCs) compounds, which are composed of hydrogen and bromine, fluorine, and carbon.
- HCFCs are compounds that are composed of hydrogen, chlorine, fluorine, and carbon. On HCFCs are a class of chemicals used to replace CFCs. They contain chlorine and thereby destroy the stratospheric ozone, but to a much lesser extent than CFCs. HCFCs have ODPs in the range from 0.01 to 0.1. HCFC high ODPs will be made in stages, in the first place, followed by other HCFCs.
- Hydrofluorocarbons (HFCs) compounds, which are composed of hydrogen, fluorine and carbon.
They are considered class replacements for CFCs, due to the fact that they contain no chlorine or bromine and do not Deplete the ozone layer. All HFC ODP-0. Some HFCs with a high GWP. HFCs are numbered according to the standard scheme.
- Methyl bromide (CH3Br) is a compound composed of carbon, hydrogen and bromine. It is an effective pesticides and used for soil fumigation and many agricultural products. Because it contains bromine, it depletes stratospheric ozone depletion potential ODP of 0.6. Its products are banned in several countries, for example, in the United States since the end of December 2000.
- Methyl chloroform (CH3CCl3) is a compound composed of carbon, hydrogen and chlorine. It is used as an industrial solvent. Its ODP 0.11.
For refrigeration applications, the number of health facilities, such as methane (R-50), ethane (R-170), propane (R-290), n-butane (R-600)and isobutane (R-600a), which are suitable as refrigerants can be used.
