Mobile air cleaning unit and distribution system

摘要

A mass transit vehicle includes a frame and a cabin mounted to the frame. The cabin includes a roof and a passenger zone defining a passenger zone length. An air cleaning unit includes an air cleaner housing mounted to the roof. The air cleaning unit is operable to draw in air through an inlet, through an air cleaning device, and discharge a flow of cleaned air out of an outlet. An air conditioning unit includes an air conditioner housing separate from the air cleaner housing. The air conditioning unit is operable to draw in air through an inlet, through an air conditioning device, and discharge a flow of conditioned air out of an outlet. The outlet of the air conditioning device is in communication with a duct system to direct the flow of conditioned air to the cabin substantially evenly along the passenger zone length.

主权项

1. A mass transit vehicle comprising:
a frame; a cabin mounted to the frame, the cabin including a roof and a passenger zone defining a passenger zone length; an air cleaning unit including an air cleaner housing mounted to the roof, an air cleaning device disposed within the air cleaner housing, an air-cleaner housing inlet upstream of the air cleaning device, and an air-cleaner housing outlet downstream of the air cleaning device, the air cleaning unit operable to draw in air through the air-cleaner housing inlet, through the air cleaning device, and discharge a flow of cleaned air out of the air-cleaner housing outlet; a duct system disposed within the cabin and extending substantially along the passenger zone length, the duct system having an clean air duct in fluid communication with the air-cleaner housing outlet and operable to receive the flow of cleaned air from the air-cleaner housing outlet and direct the flow of cleaned air to the cabin substantially evenly along the passenger zone length; and an air conditioning unit including an air conditioner housing separate from the air cleaner housing, an air conditioning device disposed within the air conditioning housing, an air-conditioning inlet upstream of the air conditioning device, and an air-conditioning outlet downstream of the air conditioning device, the air conditioning unit operable to draw in air through the air-conditioning inlet, through the air conditioning device, and discharge a flow of conditioned air out of the air-conditioning outlet, wherein the air-conditioning outlet of the air conditioning device is in communication with air-conditioning duct of the duct system to direct the flow of conditioned air to the cabin substantially evenly along the passenger zone length, wherein the clean-air duct is disposed within the air-conditioning duct and configured to discharge the flow of cleaned air inside the air-conditioning duct wherein the flow of conditioned air and the flow of cleaned air are mixed within the duct system.
