Answer:
filter drier
Explanation:
Any refrigeration or air conditioning system needs filter driers as a crucial part. In a refrigeration or air conditioning system, a filter drier serves two crucial purposes: first, it adsorbs system impurities like water, which can produce acids, and second, it provides physical filtering. To guarantee optimal and cost-effective dryer design, each component must be evaluated. The most crucial role of a dryer is to be able to drain water from a refrigeration system. Water can originate from a variety of places, including motor windings, equipment leaks, retained air from poor drainage, and others.
