What role does the condenser coil play in the HVAC system?

The condenser coil plays a critical role in the HVAC system by releasing heat from the refrigerant to the outside air. During the refrigeration cycle, the refrigerant absorbs heat from the indoor air as it moves through the evaporator coil. Once it has absorbed this heat and turned into a gas, it travels to the condenser coil.

In the condenser, the refrigerant gas is expelled into the coil, which is typically located outside the building. Here, it is cooled down by the outside air being blown over the coils, allowing the refrigerant to release the heat it absorbed indoors. As the refrigerant loses heat, it condenses back into a liquid form, ready to flow back into the evaporator coil to complete the cycle. This process of releasing heat is vital to maintaining a comfortable indoor environment and is a fundamental aspect of how HVAC systems operate effectively.
