| 20090126901 | EXTERNAL NOISE REDUCTION OF HVAC SYSTEM FOR A VEHICLE - A HVAC system for a vehicle that includes a propulsion system, a frame, a passenger compartment, and a door coupled to the frame. The HVAC system includes a refrigeration circuit that selectively controls the temperature of the passenger compartment based on a sensed temperature within the passenger compartment. The refrigeration circuit includes an exterior heat exchanger, a first air moving device coupled to the exterior heat exchanger, an interior heat exchanger, a second air moving device coupled to the interior heat exchanger, and a compressor. The HVAC system also includes a controller that is operable to detect a condition of the vehicle that includes at least one of a position of the door, a location of the vehicle, and a load of the propulsion system. The controller is programmed to adjust the refrigeration circuit in response to the sensed passenger compartment temperature and the detected vehicle condition. | 05-21-2009 |
| 20110028078 | MOBILE AIR CLEANING UNIT AND DISTRIBUTION SYSTEM - A mass transit vehicle including a cabin mounted to a frame and 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 housing, an inlet upstream of the air cleaning device, and an outlet downstream of the air cleaning device, and a duct system disposed within the cabin and extending substantially along the passenger zone length. The air cleaning unit is operable to draw in air through the inlet, through the air cleaning device, and discharge a flow of cleaned air out of the outlet, and the duct system is in fluid communication with the outlet and operable to receive the flow of cleaned air from the outlet and direct the flow of cleaned air to the cabin substantially evenly along the passenger zone length. | 02-03-2011 |

| 20110123694 | TABLE WITH ETHYLENE SCRUBBER - A display table for supporting produce includes an enclosure, a table top defining an upper surface of the enclosure, a blower, an ethylene scrubber and an outlet. The table top is open to the atmosphere and configured to support the produce, and includes perforations. The blower is positioned in communication with the enclosure to create an underpressure that draws a gas into the enclosure through the perforations. The ethylene scrubber is positioned in communication with the enclosure and in a flow path of the gas, the ethylene scrubber being configured to remove at least a portion of ethylene from at least a portion of the gas. The outlet is located downstream of the ethylene scrubber for returning the gas from the enclosure to the atmosphere. | 05-26-2011 |
