Refrigerants 2007-08-20 16:42:00 Regardless of the type, all air conditioning systems function according to a basic law of physics that states ‘a fluid absorbs heat as it changes from a liquid to a gas, and a vapor releases heat as it changes from a gas to a liquid.’ In an A/C system, refrigerant is the transfer medium used to absorb the heat inside the passenger compartment and release it to the outside air. Refrigerant is a tasteless, odorless gas with an ability to change state rapidly within a specific temperature range. It is also oil soluble and non-corrosive. While there are scores of refrigerants on the market, there are only two types approved by vehicle manufacturers: R-12 and R-134a. R-12, commonly referred to as Freon, has long been used as the refrigerant in all automotive A/C systems. However, R-12 contains chlorine, which is the primary cause of ozone layer damage. Consequently, legislation was passed calling for a halt in R-12 production by 1996. Long before the phase-out of R-12 began however, the
A/C Recharging Method 2007-08-20 16:42:00 Push-Button Dispensing With Measure & Charge (MAC-134) and EZ Charge (SD-134), dispensing refrigerant is as simple as pressing a button. You just connect the hose to the low-pressure port, press the button on the can to fill (to "charge") and release to stop. With Measure & Charge, releasing the button will automatically give you a pressure measurement on the in-line gauge (which is re-usable). Both let you store unused refrigerant for later. Both contain the appropriate proportions of refrigerant and oil, as well as System-Safe leak sealer. See full instructions on this site or on the can. Trigger Dispensing With the Quick Charge charging gun (QC-1CS and QCK-2CS), you simply connect the hose to the low-pressure port, screw a can of refrigerant into the Quick Charge, squeeze the trigger to dispense and release to stop. Quick Charge will automatically give you a pressure reading on the built-in gauge. Quick Charge is completely re-usable. See full instructions on this site or on t
