When the A/C button is pushed on the center console, the air compressor is activated by an electro-magnetic clutch. This enacts the pressurization of refrigerant for the condenser before it’s ultimately sent to the evaporator. Temperatures within the evaporator are gauged and regulated by the ...
The selection of refrigerant for an application is a balance of competing properties and it can be difficult andrnconfusing to choose between two alternatives that have very different properties. The introduction of HFOs,rnparticularly lower flammability refrigerants, has made this comparison even more ...
R-1234yf (HFO-1234yf): To replace the phased-out R-134a, manufacturers created R-1234yf (also called HFO-1234yf), a hydrofluoric-olefin refrigerant. R-1234yf is an even more environmentally friendly refrigerant. It should be in cars manufactured after 2021, though you may find i...

Retrofits from R-22/mineral oil to HFC/ polyolester (POE) oil are known to cause contamination deposits to dislodge and move through the system, so this is a very important step in any retrofit of an R-22 system. Part Three: High-Glide Refrigerant Blends & System Retrofits Included are...
In 2013, however, the auto industry initiated another change, this time to HFO-1234yf, which is believed to be the most environmentally sound refrigerant yet conceived. With this latest development, cars pose a smaller environmental threat in cases where the refrigerant leaks. What Are the ...
