What is the function of a cold refrigerant in refrigeration systems?

The function of a cold refrigerant in refrigeration systems is to extract heat and moisture from the environment. This process is essential for maintaining low temperatures within the refrigerator or air conditioning unit. When the refrigerant circulates through the system, it absorbs heat from the interior, thereby cooling the air or the items stored within the refrigerator. As the refrigerant absorbs heat, it changes from a liquid state to a gas, allowing for continuous heat exchange within the system.

Furthermore, during this process, the refrigerant also plays a role in removing moisture from the air, contributing to a drier and more effective cooling environment. This is crucial for preventing ice buildup and maintaining food quality in refrigeration applications. The overall cycle of absorption and release of heat is what enables refrigeration systems to keep spaces cool and preserve perishables effectively.
