What is a chiller primarily used for in F-Gas systems?

A chiller is primarily used for cooling in F-Gas systems. It operates by removing heat from a fluid, typically water or a mixture of water and antifreeze, and transferring it elsewhere, which lowers the temperature of that fluid. This cooled fluid can then be circulated to an area that requires temperature regulation, such as a building or industrial process.

Chillers are integral to air conditioning systems and industrial processes that require a controlled environment, making them essential in various applications like food preservation, pharmaceuticals, and comfort cooling in buildings.

The other options do not align with the primary function of a chiller. For instance, the role of heating is typically served by heaters or boilers, while the storage unit for refrigerants suggests a different kind of equipment entirely, like a refrigerant cylinder or tank. Electrical control systems are crucial for managing operations of chillers but do not define the chiller's primary purpose. Thus, the correct answer reflects the fundamental operation of a chiller in cooling applications.
