The role of a filter drier in a refrigeration system includes which of the following?

The function of a filter drier in a refrigeration system is primarily focused on maintaining the integrity and efficiency of the refrigerant throughout the system. Specifically, it is crucial for removing contaminants such as particles, moisture, and acids that can compromise the refrigeration cycle.

Moisture is particularly detrimental as it can lead to the formation of ice, which can block refrigerant flow and cause system inefficiencies or even mechanical failure. Additionally, moisture can react with acids in the system or with refrigerants, leading to corrosion and further system degradation. By removing these unwanted elements, the filter drier helps to ensure that the refrigeration system operates smoothly and effectively.

While other components play roles in regulating pressure, controlling flow rates, and stabilizing temperatures within the system, these are not the primary functions of the filter drier itself. Its main purpose is to safeguard the system by ensuring a clean and dry refrigerant environment.
