| 20100258642 | ENVIROMENTAL CONTROL SYSTEMS AND METHODS OF CONFIGURING ENVIRONMENTAL CONTROL SYSTEMS - An environmental control system of a building utilizes lower vents which open into lower portions of rooms of a building, and upper vents which open into upper portions of rooms of the building. When the system is operating in a heating mode, heated air is delivered into the upper portions of the rooms through the upper vents and air is removed from the rooms through the lower vents. 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 environmental control system to the upper and lower vents. | 10-14-2010 |

In some preferred embodiments the climate control devices are attached directly to stationary exercise devices. | 04-30-2009 |
| 20100102135 | Method for Controlling a Multi-Zone Forced Air HVAC System To Reduce Energy Use - In a multi-zone control system for central forced air HVAC systems where the minimum conditioned airflow produced by the HVAC equipment significantly exceeds the airflow capacity to many of the zones, the invention is an energy saving method for choosing non-calling zones to receive excess airflow in. When satisfying calls for conditioning from one or a few zones, excess conditioned airflow is directed to non-calling zones. The method chooses occupied non-calling zones using a priority that provides comfort, and chooses unoccupied non-calling zones using a different priority that provides energy savings. Limits are provided for each zone to prevent excessive over conditioning in non-calling zones. | 04-29-2010 |
