What occurs when refrigerant condenses?

When refrigerant condenses, it releases heat. This process occurs when the refrigerant vapor passes through the condenser coil; as it loses thermal energy and transitions from a gas to a liquid state, it expels heat into the surrounding environment. The release of heat is crucial in the refrigeration cycle because it helps maintain the flow of refrigerant, allowing it to circulate and continue cooling in various segments of the system.

The significance of this heat exchange is that it is integral to the efficiency and effectiveness of HVAC systems, enabling them to regulate indoor temperatures effectively. This phase change is also associated with an increase in pressure, which is a necessary component for maintaining the cycle of refrigeration. Understanding this concept is fundamental for HVAC technicians, as it impacts system performance and troubleshooting.
