Abstract: A heat exchange system and method for heating outside air provided to a structure are disclosed. The system uses and recovers heat from waste products that are being exhausted from the structure. A heated products source generates heated waste products as a result of combustion. An exhaust duct passes the heated waste products through a heat exchanger before exhaustion from the structure. An intake duct that supplies fresh outside air to the structure also passes through the heat exchanger. The heat exchanger couples the exhaust duct and the intake duct and transfers otherwise unused heat from the waste products to the outside air to increase the overall efficiency of the heated product source.

A plurality of turbines are carried on a common shaft for rotation therewith. Each of the turbines is positioned within the enclosure for drawing air into the enclosure and frictionally heating the air therein. A first conduit is in fluid communication with the air outlet, a water heater and an air conditioning system, for moving frictionally-heated air from the air outlet to one or the other of the water heater and the air conditioning system. A motor assembly including a motor is operatively connected to the common shaft and positioned outside the enclosure for driving the common shaft and turbines.

Abstract: A semiconductor manufacturing facility is provided, which can reduce a thermal load in a clean room and reduce an amount of energy thereof. Semiconductor manufacturing equipment, which generates heat when it is used, is installed in the clean room and is covered by a housing. The housing is configured to be capable of introducing the air inside the clean room into an interior thereof. The air inside the housing is exhausted outside the clean room through a plurality of exhaust passage members. A heat insulating material is associated with the housing to reduce the release of heat from the housing to the air inside the clean room. A space between the housing and the semiconductor manufacturing equipment may be hermetically sealed, and an air introducing member may be connected to the housing to take air outside the clean room into the hermetically sealed space.

Abstract: The need to maintain the quality of air in a home has become more of a problem in new high efficiency tight houses so that governmental regulations are being proposed for a minimum change of fresh air. If too much cold outside fresh air is introduced into such homes at a single source, the room with the fresh air is usually too cold and/or unbalanced. The present invention avoids cooling any one room while maintaining heat efficiency. When the home has a gas fireplace, the exhaust gases are preferably directed through an air-to-air cross flow heat exchanger which preheats the quality air passing into a forced air furnace system. In modified embodiments of the present invention, make-up quality air is mixed with the room air and heated in the heat exchanger of the fireplace. The preheated room air from the fireplace is preferably connected to the supply/return of a forced air furnace system and distributed to all rooms to provide uniform heating.

Abstract: A fairing vent comprising a louver rotatably attached to a body, and a louver handle attached to the louver, and a method of installing the fairing vent on a vehicle fairing. The body contains a duct having a duct intake and a duct outlet. The louver is sized to block airflow through the duct when the fairing vent is in the closed position. The fairing vent is closed by rotating the louver using the louver handle until the louver blocks airflow through the duct. A lip is disposed around the duct intake. At least one resilient tab is disposed on the body, each resilient tab being biased away from the body at an angle of approximately 10 degrees. Each resilient tab is disposed a sufficient distance from the lip so as to sandwich the thickness of a vehicle fairing between the lip and the resilient tab(s). The fairing vent is installed on the fairing by cutting a fairing cutout into the fairing. The fairing cutout is sized to admit the body but not the lip.

Abstract: In a combustor for supplying combustion heat to a heater core and an intake side of an engine, when the engine is started, combustion gas is supplied to an intake side of the engine while non-combustion air is introduced into a combustion gas passage partitioned from a water passage of the heater core by a heat-conduction partition member. In this case, non-combustion air is used as an air curtain for interrupting a heat transmission from the combustion gas of the combustion gas passage to water of the water passage.

Abstract: A method for operating a boiler including sensing a demand for heat and generating and ignition request to a flame safety controller. An ordered succession of evaluation modes compares normal operation to actual operation of control devices through the step of controlled ignition and transitions to a failure mode if an evaluation mode is not successfully completed. In addition, a series of status modes with each status mode being represented as an input condition are tested. A relative priority structure is established among the status modes and a unique message is associated with each status mode having an input condition that is true. Testing of the individual status modes proceeds in a predefined order until a status mode in a true condition is found and the unique message is displayed.

The flow through the solar collectors is regulated to maximize energy collection.

Abstract: A counterweight biased duct vent closure and door for a conventional overhead or surface mounted forced hot/cool air supply vent opening. The closure door includes a covering sized to fit over and sealably cover the register or vent opening from communication with the conditioned space when the HVAC system is not in use while automatically opening the cover to provide for treated or forced hot/cool air to be allowed into a space. The duct vent closure provided with an extension forming a counterweight spaced from and rotatable along with the door about a hinge in response to an increase and decrease in air pressure from the duct. Upon generation of a positive air pressure through the duct, the force of air pressure overcomes the gravitational bias provided by the counterweight and the covering is automatically pushed open away from the frame of the apparatus thus enabling the forced air to emanate from the vent and into the room.
