What is the primary purpose of the receiver-dryer in a vapor-cycle cooling system?

The primary purpose of the receiver-dryer in a vapor-cycle cooling system is to remove moisture and contaminants from the refrigerant. This component plays a crucial role in ensuring the efficient operation of the cooling system. Moisture in the refrigerant can lead to the formation of ice within the system, which can block refrigerant flow and reduce the overall efficiency of the cooling process. Additionally, contaminants can cause wear and damage to various system components.

By effectively eliminating moisture and impurities, the receiver-dryer helps maintain the reliability and longevity of the vapor-cycle system, ensuring optimal performance over time. This function is critical in preserving the integrity of the refrigerant and protecting the components of the air conditioning system from damage.
