About Air-Cond Expansion Valve
The expansion valve’s place in the system is at the cooling coil (evaporator) inlet. Its job is to control flow; the amount of refrigerant entering the cooling coil (evaporator). Depends on car cabin cooling demand, it is able to adjust the amount of refrigerant entering the cooling coil (evaporator).
If it was allowed too much refrigerant to enter the evaporator, it would get too cold, and the moisture collected on it could freeze. This would not allow the hot interior air to pass through its fins, and the refrigerant flowing inside the evaporator would not be able to absorb the heat from the air. This would eventually bring cooling to a halt.
If it was allowed too little refrigerant to enter the evaporator, there may not be enough to properly absorb the interior heat, which would also result in inadequate, or no cooling. This process of varying refrigerant flow based on system cooling demand is referred to as “metering” the refrigerant into the evaporator.
Things that can go wrong with Expansion Valve
Expansion valves may fail in these three ways, could cause the wrong amount of refrigerant to be metered into the evaporator, and lead to improper system operation:
