By extracting heat from the outside air, even in cold temperatures, ASHPs can efficiently warm indoor spaces. They can also reverse the process to provide cooling during warmer months.
ASHPs are a key component in the transition towards renewable energy sources, reducing reliance on fossil fuels and lowering carbon emissions. They are versatile, suitable for a range of properties, and can be integrated with existing heating systems. Understanding how these systems work is crucial for anyone considering their installation or maintenance.
How Air Source Heat Pumps Work
At the heart of an air source heat pump is a refrigeration cycle, similar to that found in a refrigerator or air conditioner. The system comprises an outdoor unit that absorbs heat from the air and an indoor unit that distributes this heat within the building. The process involves a refrigerant that circulates between these units, undergoing phase changes to absorb and release heat.
The cycle begins with the refrigerant absorbing heat from the outside air, causing it to evaporate. This gaseous refrigerant is then compressed, increasing its temperature. The hot gas passes through a heat exchanger, transferring its heat to the indoor unit. As the refrigerant cools, it condenses back into a liquid, ready to repeat the cycle.
