- If they are used responsibly, hydrocarbons can be employed in a variety of refrigeration and air conditioning applications. In order to ensure safety, hydrocarbon applications are governed by various international, regional and national standards and regulation.he refrigeration properties of hydrocarbons, such as pressures, pressure ratios and discharge temperatures, are quite similar to those of HCFCs or HFCs in many respects. The most commonly used hydrocarbons (propane and isobutane) are compatible with standard oils and materials used with HFCs.

Chlorofluorocarbon A chlorofluorocarbon (CFC) is an organic compound that contains only carbon, chlorine, and fluorine, produced as a volatile derivative of methane, ethane, and propane.They are also commonly known by the DuPont brand name Freon.The most common representative is dichlorodifluoromethane (R-12 or Freon-12).ecause CFCs contribute to ozone depletion in the upper atmosphere, the manufacture of such compounds has been phased out under the Montreal Protocol, and they are being replaced with other products such as hydrofluorocarbons (HFCs) (e.g., R-410A), hydrocarbons, and CO 2.

Freon Their product was dichlorodifluoromethane and is now designated Freon-12, R-12, or CFC-12. The number after the R is a refrigerant class number developed by DuPont to systematically identify single halogenated hydrocarbons, as well as other refrigerants besides halocarbons.

Hydrocarbons Aliphatic hydrocarbon solvents, petroleum hydrocarbon solvents. The aliphatic hydrocarbons may be of straight chain, branched or cyclic molecular structure. Aliphatic hydrocarbons such as alkanes, isoparaffins and alkenes are the major components of gasoline. Many solvents can contain a blend of different aliphatic types or aliphatic and aromatic hydrocarbons depending on the end use. Common aliphatic solvents are e.g. mineral spirits, petroleum naptha, petroleum distillate, cyclohexane, octane, pentane or isopentane, nonane.

HFC Refrigerants Used in Commercial Air Conditioning The most popular hydro-fluorocarbon (HFC) refrigerants for new commercial air conditioning systems include R-410A, R-407C and R-134a. As a facility manager or owner, it’s important that you understand these different refrigerants so that you can make informed decisions for your facility’s air conditioning system.

- The latent heat given up as the refrigerant changes from. vapor to liquid is carried away to the environment by a. cooling medium (air or water). Thus, there are two types. of condensers: air-cooled and water-cooled. • Air-cooled condensers resemble the “radiators” that cool. automobile engines.

HFCs HFCs. see chlorofluorocarbons chlorofluorocarbons(CFCs), organic compounds that contain carbon, chlorine, and fluorine atoms. CFCs are highly effective refrigerants that were developed in response to the pressing need to eliminate toxic and flammable substances, such as sulfur dioxide and ammonia, in.....

- Freon is a refrigerant used for most home heating, ventilating, and air conditioning (HVAC) units in America. While only a brand name of DuPont, the name “freon” often represents all HCFC refrigerants.The makeup of freon includes hydrogen, carbon, fluorine, and chlorine, or HCFC (hydro chlorofluorocarbons).CFC was created to take the place of a refrigerant containing carbon, fluorine, and chlorine, or CFC (chlorofluorocarbons). It was argued that HCFC was safer than CFC because HCFC is nonflammable, nontoxic, noncorrosive, and odorless.

What are the Different Types of Refrigerant Gas? Refrigerant gas is a chemical product used in refrigerators, freezers, air conditioners and heating, ventilating and air conditioning units (HVAC).These gases, which have very low evaporation points, are condensed under pressure to chill the air.efrigerant gas is a chemical product used in refrigerators, freezers, air conditioners and heating, ventilating and air conditioning units (HVAC).

- Therefore, alkanes, alkenes, and alkynes are all aliphatic hydrocarbons.) These types of compounds react in different ways, so it is possible to distinguish between them using experimental tests. Physical Properties Since hydrocarbons contain only carbon and hydrogen, all hydrocarbons are nonpolar.

- The Ring Carbons can be arranged in a ring, such as cyclobutane. Unsaturated Hydrocarbons A hydrocarbon that contains one or more double or triple bonds is an unsaturated hydrocarbon. There are three types of unsaturated hydrocarbons alkenes, alkynes, and aromatic hydrocarbons.Alkenes Many fruit bearing plants produce ethene, which controls the rate at which fruits ripening. Alkynes Alkynes are the most reactive hydrocarbon compounds.here are three types of unsaturated hydrocarbons alkenes, alkynes, and aromatic hydrocarbons.

Hydrocarbon Saturated hydrocarbons are the simplest of the hydrocarbon species. They are composed entirely of single bonds and are saturated with hydrogen. The formula for acyclic saturated hydrocarbons (i.e., alkanes) is C n H 2n+2. The most general form of saturated hydrocarbons is C n H 2n+2(1-r), where r is the number of rings. Those with exactly one ring are the cycloalkanes. Saturated hydrocarbons are the basis of petroleum fuels and are found as either linear or branched species.

- This type of refrigeration system takes advantage of the fact that the solubility of ammonia in water changes as the temperature of the system changes. This type of refrigeration is beyond the scope of Thermo-CD, but you should be aware of its existence.

What are the different types of hydrocarbons? Aliphatic hydrocarbons are compounds of hydrogen and carbon that do not contain benzene rings. We'll discuss compounds with benzene rings later in this lesson. Aliphatic hydrocarbons tend to be flammable. There are several types of aliphatic hydrocarbons: alkanes, alkenes, alkynes and alkenynes.

Hydrocarbon Toxicity Halogenated hydrocarbons are a subgroup of aromatic hydrocarbons, in which one of the hydrogen molecules is substituted by a halogen group. The most important halogenated hydrocarbons include carbon tetrachloride, trichloroethylene, tetrachloroethylene, trichloroethane, chloroform, and methylene chloride.ydrocarbon pneumonitis results from a direct toxic affect by the hydrocarbon on the lung parenchyma. The type II pneumocytes are most affected, resulting in decreased surfactant production. This decrease in surfactant, results in alveolar collapse, ventilation-perfusion mismatch, and hypoxemia.

Guide to Air Conditioning & Heat Pump Refrigerant Gases Refrigerant gas names, properties & uses Refrigerant gas controls & metering Devices Refrigerant Piping & Leak Detection Ammonia is the oldest-known refrigerant. (Ammonia can generate cooling by simple mechanical movement). Ammonia vapor can be flammable, explosive, and toxic. Ammonia is lighter than air (so less likely to accumulate at a dangerous level near the floor).
