Technical Information: AC Condenser Like the name says, it will condense the refrigerant that circulates through the condenser. At this point, this is where the refrigerant must release heat. Heat is removed from the condenser in many ways. First, when the A/C system is engaged an electric or engine driven cooling fan pulls fresh air through the condenser. Second, the front grill enables outside surrounding air to flow to the condenser. Some more aerodynamic vehicles have no front grill to let fresh air from the outside in. These vehicles use special air deflectors located under the front body to direct air flow when the fan is running or the vehicle is in motion. Last, the majority of vehicles have deflectors located between the condenser and the front grill to concentrate distribution of fresh air to the condenser. Presently four specific condenser models are available in the automotive industry. Condensers have specifically changed design to be able to cool better the refrigerant in a smaller square inch surface. The Parallel flow condenser is the most efficient of the four. The problem with the parallel flow is that the passages are very small and if the compressor fails the condenser will clog. This unit cannot be flushed. It is recommended to replace the unit if a catastrophic compressor failure occurs or the newly installed compressor will fail in a short period of time. When replacing a condenser, add the recommended amount and type of refrigerant oil and to ensure system dryness, replace the accumulator/drier. |
