What liquid is used for car AC?

Which coolant is best for AC?

The most common HFC used in air conditioners is R-410A. This refrigerant is better than R-22 in terms of “Ozone Depletion” potential and energy efficiency, but it still causes global warming. A few more HFCs that are commonly used are: R-32 in Air Conditioners and R-134A in refrigerators.

What chemical is used in car air conditioners?

The refrigerant R1234yf is being considered for use in air conditioning systems in cars. Chemists now show that, in the event of a fire, it releases the highly poisonous carbonyl fluoride, and urge that its safety be reassessed. The refrigerant R1234yf is being considered for use in air conditioning systems in cars.

What makes car AC colder?

The heart of any air conditioning system is a compressor whose job it is to compress the freon. When the freon later expands, it gets very cold. Air blown across metal filled with cold freon causes the air to cool quickly.
