  • Patent number: 8256241
    Abstract: A centrifugal fan mounted in an air conditioner has the following relationship: outer diameter of a side plate of the centrifugal fan > outer diameter of the blade rear-edge part on side-plate side > diameter of the blade rear-edge part on main plate side ? outer diameter of the main plate. In the centrifugal fan, the blade rear-edge part is positioned inside from a straight line connecting the connection point between the blade rear-edge part and the main plate, to the connection point between the blade rear-edge part and the side plate, as viewed from the rotation axis. The blade rear-edge part has a shape such that the distance from the rotation axis becomes larger from the main plate toward the side plate.

  • Publication number: 20120159974
    Abstract: A refrigerator, the temperature of the inside of which is uniformly controlled, and a control method thereof. The direction of an air flow in a storage chamber is periodically changed so as to uniformly distribute cool air in the storage chamber by interchanging roles of suction and discharge holes in various manners under various conditions, thereby preventing local supercooling and thus uniformly maintaining the internal temperature of the storage chamber.

  • Publication number: 20120096886
    Abstract: A personal cooling system, such as for a cabless or other open-cab vehicle, includes a contact cooler that contacts the vehicle user, a forced-air cooler that directs cooled air to the vehicle user, and a recirculating fluid system that is operatively coupled to both the contact cooler and the forced-air cooler to provide cooling to both the contact cooler and the forced-air cooler. Contact cooling may be provided to the upper back of a vehicle user. Forced-air cooling may be provided on any of a number of areas of the user's body. The system may be able to detect the presence of a user in the seat. The detection of a user may trigger an initial relatively high level of cooling, which is followed after a predetermined time by a reduction of the level of cooling to a relatively low level of cooling.
