Which of the following refrigerants is likely to be included in a closed-cycle compression refrigeration system?

In a closed-cycle compression refrigeration system, refrigerants are necessary to absorb heat from an area, thereby cooling it, and then release that heat elsewhere during the refrigeration cycle.

Water is sometimes used as a refrigerant in certain applications, particularly in absorption systems, although it's less common for compression refrigeration cycles due to its high boiling point and low efficiency in those systems. However, its properties can sometimes make it suitable for specific scenarios, especially when large cooling capacities or low temperatures are not required.

Ammonia is a traditional refrigerant used in many industrial applications. It has excellent thermodynamic properties, such as a high latent heat of vaporization and low energy consumption, making it ideal for closed-cycle compression refrigeration systems. It is particularly effective in large, centralized cooling systems.

Freon, which is a brand name for a series of halocarbon refrigerants, is also a common choice in many household and commercial refrigeration systems. It's known for its low toxicity and excellent thermodynamic characteristics, making it widely used in closed-cycle systems.

Considering these options, it is accurate to state that all three—water, ammonia, and Freon—can have roles in refrigeration systems, depending on the specific design and application requirements. Thus, the inclusion of all of
