What is the primary purpose of refrigerant in a refrigeration system?

The primary purpose of refrigerant in a refrigeration system is to absorb and release heat. This process is crucial for the operation of the refrigeration cycle, which involves the refrigerant evaporating in the evaporator, absorbing heat from the environment, and then condensing in the condenser, where it releases that heat to the outside. This cycle effectively lowers the temperature inside the refrigerated space or process by continuously removing heat and maintaining desired temperature levels.

Understanding the refrigerant's role in heat transfer is essential because it enables the refrigeration system to cool effectively, ensuring that the desired temperatures are achieved and maintained.
