What is the primary purpose of a filter drier in a refrigeration system?

The primary purpose of a filter drier in a refrigeration system is to remove moisture and contaminants. Moisture can significantly affect the efficiency and longevity of refrigeration systems, as it can lead to the formation of ice, which can block the flow of refrigerant and cause system malfunctions. Additionally, contaminants like dirt and debris can clog components, causing wear and reducing efficiency. The filter drier plays a crucial role in maintaining the purity of the refrigerant circulated within the system, ensuring that it operates reliably and effectively. By absorbing moisture and filtering out impurities, the filter drier helps to enhance the overall performance and durability of the refrigeration system.
