Process of Air Heat Pump
Evaporation
In heating mode, the refrigerant inside the evaporator coil absorbs heat from the surrounding air. The liquid refrigerant evaporates into a low-pressure gas as it extracts thermal energy from the indoor air or outdoor environment.
Compression
The low-pressure, gaseous refrigerant is then compressed by the compressor. This compression process increases the temperature and pressure of the refrigerant, transforming it into a high-energy, high-temperature gas.
Condensation
The hot, pressurized gas flows into the condenser coil, releasing the absorbed heat to the indoor space. As the refrigerant condenses back into a liquid state, it releases the stored heat, which is then circulated through the building via the air distribution system.
Expansion valve
The liquid refrigerant passes through an expansion valve, causing it to rapidly expand. This process lowers its temperature and pressure, preparing it for the next cycle.
Evaporation
In cooling mode, the now cold refrigerant circulates through the indoor coil, absorbing heat from the indoor air. This heat absorption causes the refrigerant to evaporate once again, cooling the indoor environment.
Condensation
The warm, gaseous refrigerant is then pumped to the outdoor unit and passes through the outdoor coil. In this phase, the refrigerant releases the absorbed heat to the outdoor air, causing it to condense back into a liquid state and completing the cycle.

In the next phase of the cycle, the refrigerant, now in the form of a high-energy, high-temperature gas, is compressed by the compressor. This process raises both the temperature and pressure of the refrigerant. The hot gas is then directed to the condenser coil, where it releases the absorbed heat into the indoor space, thereby increasing the temperature during the heating mode.
The refrigerant undergoes phase changes, transitioning between liquid and gas states, as it moves through the different components of the air heat pump. These phase changes are fundamental to the absorption and release of heat, allowing the system to operate effectively in both heating and cooling modes.
In the cooling mode, the refrigerant absorbs heat from the indoor air in the evaporator coil, and the compressor raises its temperature and pressure. The hot gas is then directed to the outdoor condenser coil, where the refrigerant releases the absorbed heat into the outdoor air. This process completes the cycle, preparing the refrigerant to absorb more heat in subsequent cycles.
