The primary purpose of the receiver/drier in an A/C system is to store and filter refrigerant. This component plays a crucial role in maintaining the efficiency and functionality of the air conditioning system.

In the process of function, the receiver/drier serves as a reservoir for the refrigerant after it has been condensed in the system. This allows for a steady supply of refrigerant to the expansion device. Additionally, the receiver/drier contains a desiccant material that absorbs moisture from the refrigerant. Moisture can cause significant damage to the A/C system by promoting corrosion and forming ice that can hinder the refrigerant flow. Therefore, the ability of the receiver/drier to filter out debris and absorb moisture is vital for the longevity and effectiveness of the air conditioning system.

Understanding this function helps in troubleshooting and maintaining A/C systems, as issues related to moisture or debris in the refrigerant can lead to system failures or reduced cooling performance.
