Question 139Refrigeration/AC - QMED70% to pass
Standard filter/driers used in many commercial type refrigeration units may contain what type of substance?
AI Explanation
The correct answer is C) activated alumina or silica gel desiccant beads.
Standard filter/driers used in many commercial refrigeration units typically contain activated alumina or silica gel desiccant beads. These materials are effective at absorbing and removing moisture from the refrigerant system, which helps prevent ice buildup and damage to the compressor and other components. Activated charcoal (option A) and alcohol-based liquid drying agents (option B) are not commonly used in these types of filter/driers.
