The evaporator serves as the core component within the air conditioning unit responsible for cooling the passenger compartment and regulating its temperature. Refrigerant, initially in a high-temperature, high-pressure gaseous state, passes through the expansion valve to transform into a low-temperature, low-pressure two-phase state. It then flows into the evaporator where it undergoes heat exchange with the external air, absorbing heat from the ambient air to achieve the cooling of the passenger compartment. Rated heat exchange capacity: 8.5 kW @ 450 m³/h, 43°C/40% inlet air conditions.
