The internal condenser serves as the core component for heating the passenger compartment and regulating temperature within the heat pump air conditioning unit. High-temperature, high-pressure gaseous refrigerant flows into the internal condenser, where it undergoes heat exchange with the external air. This process releases heat to the external air, thereby achieving the objective of heating the passenger compartment. Rated heat exchange capacity: 14 kW @ 467 m³/h, with an inlet air temperature of -10°C.
