Railway vehicle air conditioning unit with integrated exhaust

Abstract

The utility model relates to a kind of integrated waste exhaust rail vehicle air conditioning unit, including shell, evaporative cavity and condensing cavity are in the shell, condenser is installed in the condensing cavity, total heat exchanger is installed in the evaporative cavity, fresh air inlet and waste exhaust inlet are provided on the shell of the evaporative cavity, condensing air outlet is provided on the shell of the condensing cavity, fresh air and waste exhaust respectively pass through the total heat exchanger and carry out heat exchange in total heat exchanger, waste exhaust passage for guiding waste exhaust after heat exchange with fresh air to condenser air inlet side is provided in the condensing cavity, waste exhaust fan is installed in the waste exhaust passage, waste exhaust is discharged by condensing air outlet after secondary heat exchange with condenser.The utility model can make the cold energy and heat in waste exhaust be fully recycled, effectively avoid that cold energy / heat in car is lost in large quantities, improve air conditioning energy efficiency.
