Within this closed and pressurized system, calibrated amounts of the proper lubricant are added and mixed with the refrigerant. Pressure to temperature relations are very important, but more on this later. The refrigerant charge level is imperative, as over or undercharging will lead to poor system performance. One cycle of the refrigeration process is now complete. The compressor accepts the low-pressure vapor, compresses it, then discharges the now compressed high-pressure vapor into the condenser. The low-pressure vapor is suctioned, or drawn, from the evaporator, then through the accumulator and back to the compressor. Then the liquid flows into the evaporator where the refrigerant boils to a vapor as it absorbs heat from the air blowing past the fins. This reduces its pressure to approximately 30 psi. Next the high-pressure liquid is forced through either an expansion valve or a fixed orifice tube, which restricts the flow of the liquid. There it condenses and changes physical state to a high-pressure liquid. The refrigerant pressure will be raised by the compressor and discharged as a hot, high-pressure vapor into the condenser. Principle of OperationĪlthough plumbing and component locations vary slightly from generation to generation among of our trucks, the concept is the same.

The blue lines are the suction/low side psi system operating pressures. Typical A/C components – Dodge Turbo Diesels (HFC 134 A) The red lines are discharge/high psi system operating pressures. How it works: Turbo Diesels have the following components: see diagram below.

Always practice safety by wearing safety glasses and protecting skin from refrigerant and refrigerant oils! If the principles of automotive air conditioning are unfamiliar, you might wish to look at the glossary of terms below for a better understanding.

If you are concerned about complying with EPA rules (those applying to professional technicians) governing the release of refrigerant into the atmosphere, add a recovery or recovery/recycling machine to your tool kit. Charging can be accomplished with the old standby 12-ounce cans, but a 30-pound cylinder and a charging scale are needed to prevent over- or under- charging the system. At a minimum, a good vacuum pump, manifold gauge set, charging stand and an accurate thermometer are necessary. A DIY repair can end up costing substantially more than a professional repair because you can’t avoid introducing moisture into the A/C system. Instead of covering “how to change a part,” let’s discuss the theory of the system’s operation and some real world technical tips not found in your factory service manual.īefore becoming a do-it-yourself A/C expert, recognize the reason your local shop charges so much: many expensive service tools are necessary to properly repair the A/C system.

And you’ll find some of the A/C parts for the DIY-er at Geno’s Garage. The pages of many prior issues of the Turbo Diesel Register magazines have been devoted to the removal of the instrument panel to replace a leaky air conditioning evaporator core (‘98-‘02), leaking heater core, flimsy blend air doors (‘03-current), etc.

Are the summer months in your truck spent with the old-school “2-60” air conditioning (two windows down at 60mph)? A properly operating HVAC system provides comfort and safety.
