Volkswagen Polo Service & Repair Manual: Evaporator

  Caution
Non-approved tools or materials such as leak sealing additives can cause damage or malfunctions in the system.
Only use tools and materials approved by the manufacturer.
The warranty is voided if non-approved tools or materials are used.
All components of the refrigerant circuit submitted for quality observation are always to be sealed (use original sealing caps of original part).
Replace damaged or leaking components of refrigerant circuit. Refer to → Chapter „Components, Replacing“.
To date, the original parts (compressor, reservoir, receiver/dryer, evaporator and condenser) have been filled with nitrogen gas. This charge is being gradually discontinued. There is little or no pressure equalization when removing the sealing plugs from the original part.
   
The fluid refrigerant evaporates in the evaporator pipe coils. The heat required for this is extracted from the air flowing on the evaporator ribbing. The air cools off. Refrigerant evaporates and is extracted with the absorbed heat by the A/C compressor.
A defined amount of refrigerant is supplied to the evaporator by a restrictor or expansion valve. In systems with expansion valve, the throughput is regulated so that only gaseous refrigerant escapes the evaporator outlet.
