Which of the following cannot be used as a desiccant in a refrigerating system?

• A. Soda lime
• B. Silica gel
• C. Calcium chloride
• D. Zeolite

Answer: (D)

In the context of refrigerating systems, desiccants are substances that absorb moisture from the refrigerant, preventing the formation of ice and improving system efficiency. While soda lime, silica gel, and calcium chloride are all effective desiccants used in various applications, zeolite is not traditionally employed for this purpose in refrigerating systems. Zeolite is a naturally occurring mineral with a porous structure primarily used for ion exchange, gas adsorption, and as a catalyst in some chemical reactions. While it can absorb moisture, its primary function is not as a desiccant to dry out refrigerating systems efficiently. Therefore, utilizing zeolite as a desiccant would not yield the same effectiveness as the other listed substances, which are primarily designed for moisture absorption in cooling applications. Understanding the properties and intended uses of these materials is crucial in selecting the appropriate desiccant for a refrigerating system, ensuring optimal performance and longevity.
