In refrigeration systems, what is the function of condenser coils?

The function of condenser coils in refrigeration systems is to release heat from the refrigerant. When refrigerant circulates through the system, it absorbs heat from the space being cooled and transitions into a gas. Once it reaches the condenser coils, which are typically located outside of the refrigerating environment, this gaseous refrigerant releases its absorbed heat to the surroundings. As the refrigerant expels heat, it cools down and condenses back into a liquid state before it is cycled back into the evaporator to continue the refrigeration cycle. This process is crucial for maintaining the efficiency and effectiveness of the refrigeration system, as it ensures that the refrigerant can continually absorb heat from the environment and remove it efficiently.
