Energy Efficient Building Products, Systems and Smart Range Hood(ST9321-1)
Robert P. Siegel
The Smart Range Hood is a sophisticated, microprocessor-controlled ventilation device that makes use of state-of-the-art sensor and control technology to respond to very low levels of hazardous cooking- related pollutants, such as carbon monoxide and smoke, in a manner that is appropriate to the level of risk. The Smart Range Hood’s fuzzy logic controller is designed to regulate the exhaust fan speed to a level that will ensure that all the hazardous substances are evacuated. Under earlier NYSERDA-funded work, Rain Mountain developed and demonstrated a proof of concept design of the Smart Range Hood. The Smart Range Hood successfully completed testing, conducted by Brookhaven National Laboratory that validated the performance of the proof of concept design. Rain Mountain is ready to develop a product design that is more practical to fabricate and install.
The Contractor (Rain Mountain) developed and tested the Smart Range Hood concept. A prototype was fabricated using existing "off-the-shelf" sensors and motor controls capable of responding to low smoke levels and carbon monoxide concentrations. The fuzzy-logic controls were programmed for the Smart Range Hood. Brookhaven National Laboratory (BNL) tested the Smart Range Hood. The final Smart Range Hood design was tested by BNL under harsh conditions to establish the robustness of the sensors. After this proof concept phase, the Contractor developed and procured lower cost and smaller sensors for the Smart Range Hood. A microcontroller was developed to operate the fuzzy logic control algorithms for the Smart Range Hood. The sensors and microcontroller were integrated into a commercially available Energy Star® rated range hood manufactured by Reversomatic Manufacturing Limited (a manufacturer of residential kitchen hoods and bathroom fans). The final Smart Range Hood system was submitted to Reversomatic for acceptance testing under actual cooking conditions.
Rain Mountain estimates the annual Statewide energy savings from installing the Smart Range Hood in 5% of New York’s homes to be almost 270 billion Btus. The Smart Range Hood has the potential to reduce the risk of carbon monoxide exposure in residential kitchens.
Rain Mountains identified and tested lower cost and smaller sensors for the Smart Range Hood. A microcontroller was developed to operate the fuzzy logic control algorithms for the Smart Range Hood. The sensors and microcontroller were integrated into an Energy Star rated range hood manufactured by Reversomatic Manufacturing Limited and functionally tested. The system was found to be responsive to cooking pollutants and operated consistently during repeated tests. The new sensor and controller design appears to meet the target cost sought by Reversomatic.
