ETFL 60 = Elevated Temperature Flame Limit @ 60 Â°C. HOC = Heat Of Combustion. Compounds used as refrigerants may be described using either the appropriate prefix above or with the prefixes R- or Refrigerant.. Thus, CFC-12 may also be written as R-12 or Refrigerant 12.An alkene, olefin, or olefine is an unsaturated chemical compound containing at least one carbon-to-carbon double bond.hemical refrigerants are assigned an R number which is determined systematically according to molecular structure.
The energy stored in a capacitor is almost entirely in the electric field produced between the plates. It takes energy from a battery or some other power source to move electrons to one of the plates and away from the other. This makes one plate positively charged and the other negatively charged.
Once the car is started, the alternator is the sole source of electrical energy for anything that needs it. -basically the capacitor will store a charge coming from your alternator to ensure no damage to your alternator or to other electric devices occurs. yes, the cap holds a charge for a few seconds, and discharges very quickly.
