When the system is operating in a cooling mode, cool air is delivered into the rooms through the lower vents, and air is removed from the rooms through the upper vents. Operating the heating and cooling modes in this fashion provides the most efficient operation of the heating and cooling system. A switching unit is used to selectively couple the inlet and outlet of an air handling unit to the upper and lower vents.Type: ApplicationFiled: July 28, 2011Publication date: November 17, 2011Inventor: DOUGLAS A.

Publication number: 20110250832Abstract: A tractor cab HVAC system has a blower (22) which draws air into the system via air intake means (13) in the roof (14) of the cab (10). Ducting (15) in the roof of the cab directs air drawn in via the intake means down the centre of one or more hollow adjacent pillars (16) of the cab to an air filter (18) contained in a housing (20) located between the adjacent pillars. Further ducting (19) extends from the air filter housing to an HVAC unit (11), the HVAC unit processing the air drawn into the system prior to discharging the processed air into the cab. The filter housing (20) is of generally rectangular form and is connected at opposite ends to the two hollow adjacent pillars (16) of the cab via inlet openings (20a) in the housing to allow the passage of intake air from the pillars to the filter (18).Type: ApplicationFiled: October 26, 2009Publication date: October 13, 2011Applicant: AGCO GMBHInventors: Stefan Mayr, Alexander Zeller, Hermann Geiss, Andreas Stieglitz

Publication number: 20110235273Abstract: A case includes a box, a top cover, a first airflow guide member, and a second airflow guide member. The box has an opening sealed by the top cover. The first airflow guide member and the second airflow guide member are fixed on at least one of the top cover and a side plate of the box. The first airflow guide member and the second airflow guide member are spaced from each other, and cooperatively define a guide channel. The box defines an inlet and an outlet communicating with the guide channel.Type: ApplicationFiled: August 23, 2010Publication date: September 29, 2011Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventors: ZEU-CHIA TAN, YAO-TING CHANG, ZHI-BIN GUAN

Publication number: 20110223848Abstract: A ventilation system including a heat recovery assembly having a first heat exchanger for heat recovery with a first flow path and a second flow path to exchange heat energy from air transported in one of paths to the other. A peripheral inlet to the first flow path is arranged to surround a central outlet of the second flow path and a peripheral inlet to the second flow path is arranged to surround a central outlet of the first flow path. The assembly further includes a peripheral outlet and a central inlet, the peripheral outlet arranged to surround the central inlet, and the heat recovery assembly is arranged such that air entering the peripheral inlet of the first flow path exits by the peripheral outlet; and air entering the central inlet will exit by the central outlet of the second flow path.Type: ApplicationFiled: March 10, 2011Publication date: September 15, 2011Inventor: Thomas Lipinski

Publication number: 20110212680Abstract: Radon Removal System comprised of an inline suction fan with “y” type fitting below it. The “y” type fitting is attached to a mounting flange that is positioned over a 4 inch hole in the sump cover or other depressurization port allowing the suction fan to draw air containing radon gas or other contaminants from drain tile(s) having fluid communication with the sump basin. The side inlet of “y” fitting draws exterior air from a flexible or solid PVC pipe located 3 or more feet from the discharge point. The suction fan draws exterior air into the side inlet of “y” fitting and dilutes the radon gas drawn into the lower opening of “y” fitting. The suction fan simultaneously dilutes the contaminated air with clean exterior air before being pumped out of outlet port. The expelled air is discharged into the outside atmosphere where it is further diluted to safe levels posing no health risk. With this system, it is no longer necessary to route the discharge pipe to the highest eve of the roof.Type: ApplicationFiled: March 1, 2010Publication date: September 1, 2011Inventor: Thomas Edward Schaefer
