What is the primary role of refrigerant in HVAC systems related to heat?

• A. Regulating airflow
• B. Managing humidity levels
• C. Carrying heat away through phase changes
• D. Maintaining a constant temperature

Answer: (C)

The primary role of refrigerant in HVAC systems related to heat is to carry heat away through phase changes. Refrigerants operate by absorbing heat from the indoor environment as they evaporate (phase change from liquid to gas) and releasing that heat outdoors as they condense (phase change from gas back to liquid). This continuous cycle of phase changes enables the HVAC system to effectively cool indoor spaces by transferring heat away from them. By using refrigerants efficiently, the system can maintain comfortable temperature levels while also playing a crucial role in the overall thermal management of the environment. Each phase change is associated with significant energy exchange, making refrigerants vital for the heat exchange processes that are central to HVAC function.
