Treated air is blown into vehicle through air duct and air outlet.
With hermetic scroll compressor, R22 refrigerant and capillary throttling, each KLD29 has 2 independent cooling recycling units. The units can be energy regulation controlled due to indoor condition and load. Integrated control cabinet is used to achieve auto, manual and centralized control of the units.
All components of KLD29 rail passenger car HVAC units: hermetic scroll compressor, evaporator, condenser, capillary tubes, gas-liquid separator, drier, filter, axial fans, centrifugal blowers, electric heaters form 2 independent systems of both cooling and heating. All components are assembled in a chamber made of SUS304 stainless steel. Silver brazing is applied for tubes and components connection. The cool air outlet is placed in the front of the unit, fresh air inlet is placed at rare of the unit, and return air inlet is placed at bottom of the unit. Condensing water can be drained separately, or concentrate drained with connectors. The unit power cables are introduced into return air outlet. Below are KBL29 technical data:
