Appl. No.:

11/010997

Inventors:

Michael Alan Garrabrant - Unicoi TN, US
Ronald Paul Soka - Toledo OH, US

Assignee:

Cooling Technologies, Inc. - Toledo OH

International Classification:

F25B 15/00

US Classification:

62148, 62476, 62483

Abstract:

An absorption, heat-transfer system with an operationally interconnected generator, absorber, condenser, and evaporator; at least two separate heat sources for heating the generator; and a controller for controlling the heat sources. The controller, e. g. , a programmed microprocessor, receives inputs from the absorption system, the heat sources, and loads and a lookup table and provides outputs to select and control the heat sources and maximize their efficiency. A heat distributor and a heat recover unit enable heat source management and additional energy utilization.

Michael A. Garrabrant - Unicoi TN, US
Roger E. Stout - Columbus OH, US
Eric Collet - Village of Minerva Park OH, US

Assignee:

Cooling Technologies, Inc. - Toledo OH

International Classification:

F25B 29/00

US Classification:

165 58, 622383, 62476

Abstract:

A waste heat source () is used to heat a high temperature heat transfer fluid which is used to heat an absorption heat transfer machine () having a generator (), an absorber (), a condenser (), and an evaporator () operatively connected together. The high temperature heat transfer fluid can also be used to heat a load () such as a room space or a process. The waste heat source () can also be used to heat an intermediate heat transfer fluid, which can be used to heat a second load () such as a space, a process, or an absorption heat transfer machine. Novel flow control devices () for controlling the flow of weak solution from generator () to absorber () or of refrigerant from condenser () to evaporator (), respectively, are also described.

Appl. No.:

11/316296

Inventors:

Michael A. Garrabrant - Unicoi TN, US
Eric Arnold - Jonesborough TN, US
Jeff L. Lyons - Gray TN, US

Assignee:

American Water Heater Company - Johnson City TN

International Classification:

F24H 9/20

US Classification:

122 1421

Abstract:

A combustion chamber is disposed below the water container of a water heater and formed at least partially by a shell. A burner disposed within the combustion chamber and a fuel supply line is connected to the burner. A valve associated with the fuel supply line. A combustion chamber sensor is disposed within the combustion chamber and adapted to sense a rise in temperature indicative of an abnormality in the combustion chamber. A circuit connected to the sensor and the valve such that the circuit triggers the valve to shut off fuel to the burner in response to a sensed temperature by the sensor.
