Air source heat pumps are designed to extract heat from the outdoor air - even in cold weather. But when frost begins to form on the outdoor coils, the efficiency of the heat exchange process becomes less efficient. If the frost is not cleared, the system cannot absorb enough heat, resulting in increased energy consumption, reduced heating output, and even possible air source heat pump system failure.
For this reason, modern air source heat pumps are equipped with a defrost system. The role of this system is to monitor the condition of the condenser and initiate the defrost function when necessary. A well-functioning air source heat pump defrost system can keep the unit running efficiently, prevent ice damage, and ensure that comfort is always maintained in low temperatures. The defrost function is essential to ensure the long-term reliability of the unit, especially in areas where frost is frequent. All Leomon heating air source heat pumps come standard with a built-in defrost system to maintain stable performance even in harsh winter conditions.
Without a defrost system, the unit will require frequent manual maintenance, otherwise air source heat pump failures may occur during peak heating periods. In large installations or light commercial scenarios, such issues can lead to service delays, customer complaints, and increased costs.
To automate this critical task, air-source heat pumps rely on a control logic called the heat pump defrost cycle – an intelligent sequence that enables the system to melt frost without user intervention.
