What is the function of drier in AC system?

The function of a receiver drier

The receiver drier is a filtering unit located on the high-pressure side of the AC loop between the condenser and the expansion valve. The receiver driers’ primary function is to receive and store some liquid refrigerant from the condenser.

What is a common symptom of a severely restricted filter drier?

A starved evaporator from the liquid line (filter drier) restriction will cause high superheats. High compression ratios from the low evaporator pressure will cause high heat of compression, thus high discharge temperatures. This is assuming there’s still some mass flow rate of refrigerant through the system.

How do I know if my liquid line filter drier is clogged?

How can you tell if you have a clogged liquid line filter drier? If there is a noticeable temperature drop from one side of the filter drier to the other, this means that there is a pressure drop. Remember that temperature follows pressure and temperature is something that we can measure on the outside of the tubing.

Do you need to replace dryer when replacing AC condenser?

The simple answer is this: the AC dryer should be replaced any time your AC system is opened for service. … If the AC system is worked on and open to the atmosphere, the desiccant can quickly become saturated from the humidity in the air.

What is an A C evaporator?

The air-conditioning evaporator is a small radiator inside the dashboard that provides cold air for the air-conditioning system. … Unlike a ruptured heater core, which can leak engine coolant into the foot wells, a leak in the evaporator releases only refrigerant vapor.
