How Do Air Source Heat Pumps Work? May 09, 2024 Air source heat pumps (ASHPs) are an innovative and energy-efficient solution for both heating and cooling buildings. They operate by transferring heat from one place to another, making use of the natural heat present in the air, even at low temperatures. This technology is not only environmentally friendly but also cost-effective, offering significant energy savings compared to traditional HVAC systems. Understanding the mechanics behind ASHPs reveals why they are becoming a popular choice for sustainable climate control. So, How Does An Air Source Heat Pump Work? Heat Absorption The process begins with the evaporator coil, which absorbs heat from the outside air. Even when the outside temperature is cold, there is still some heat present in the air. The evaporator coil, filled with a refrigerant, captures this heat efficiently. Heat Compression Once the refrigerant absorbs the heat, it moves to the compressor. The compressor plays a crucial role by compressing the refrigerant gas, significantly increasing its temperature. This step is essential for raising the heat to a level that can be used for warming the building. Heat Release After compression, the hot refrigerant gas travels to the condenser coil. Here, the refrigerant releases the absorbed heat into the indoor air. As the heat is transferred, the refrigerant cools down and returns to a liquid state, ready to repeat the cycle. Reversal for Cooling In warmer months, the system can reverse the process. By reversing the flow of the refrigerant, the heat pump extracts heat from the indoor air and releases it outside, effectively cooling the building. This is achieved through a reversing valve that switches the function of the evaporator and condenser coils. This efficient cycle of heat absorption, compression, and release allows air source heat pumps to provide both heating and cooling, making them a versatile and eco-friendly option for climate control in buildings.
