I don't believe that expansion Valve A/C are used on Explorers, not my in my Mazda Navajo at any rate. I've added it to this forum though because of a mistake I made in another thread. Having serviced EV systems in the Navy and Air Force there are some terms and assumptions that I carried into a discussion on an the Ford orifice system that unecessarily confused a participant.
I won't describe the system principles of operation but I'd like to point out the differences
1. The orifice system uses an accumulator, the EV system uses a receiver drier. These are somewhat similar in purpose and the terms are often used interchangeably.
2. The accumulator on an orifice system is on the low pressure side. In the EV system the receiver/drier is on the high pressure side. These are NOT interchangeable. It is common practice on an EV system to pour the refrigerant into the Receiver/Drier. It is NOT recommended to pour liquid refrigerant into the accumulator.
3. The orifice system uses an ... orifice, the expansion valve system uses an .... expansion valve. Again the terms are used interchangeably - the expansion valve system contains a few more components and is more versatile.
Generally speaking cross referencing terms is no harm, we generally know what people mean. But if anyone wonders why different terms are sometimes used, hopefully this reduces the confusion.
