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. |
