So, the industry has been working on new, eco-friendly versions like HCFCs. In the HVAC industry, “Freon” is often used as a general term for refrigerant or cooling agent. While typically stable and non-flammable, these refrigerants can be mildly toxic and have a characteristic odour simil...
The three common car refrigerants are R-12, R-134a, and R-1234yf. Different refrigerant types require different charging hoses, so check which one your vehicle is it in earlier models. R-12: R-12 is the original chlorofluorocarbon (CFC) Freon used in car A/C systems until t...
You also need to retire or retro-lift a unit if it exceeds its acceptable leak rate for two consecutive quarters. The acceptable leak rate will vary based on the type of refrigeration system and refrigerant used. If you need to install new equipment, the new unit must have an automatic ...
Chemically speaking, a hydrocarbon [HC] is an elemental compound of hydrogen and carbon that occurs naturally and is found in high concentrations in crude oil. Used as a modern refrigerant, non-toxic hydrocarbons are an environmentally friendly alternative to CFC/HCFC/HFC fluorocarbons linked to oz...
Today automobiles use either R-134a (which is being phased out) or R-1234yf refrigerants. Refrigerant has a very, very low boiling point. Air conditioning refrigerant is used to remove heat from the car’s cabin to outside the vehicle through the properties of evaporation. Throughout the ...
