20170234549 · 2017-08-17 ·

Synergistic Energy Ecosystem using a co-generation system and method wherein waste energy from waste heat producers within an enclosure including an electric generator is reclaimed to supply heat to the cold end of a heat pump within the enclosure for optimized use in space heating a habitat and to the management of the distribution of electricity from the generator so as to supply electricity to the habitat and to neighbouring habitats when efficient, cost-effective or required to do so by distribution policies managing the energy eco-system.

Heat Extractor to Capture and Recycle Heat Energy within a Furnace
20170219246 · 2017-08-03 ·

A heat extractor captures and separates the heat and the carbon monoxide from waste energy that is expelled from the furnace as an unusable bi-product. The heat extractor includes a core assembly, a furnace flue pipe inlet, and a furnace flue pipe outlet. The heat extractor is secured within a return air duct of the furnace, while a furnace outlet is connected to the furnace flue pipe inlet and the furnace flue pipe outlet is connected to a chimney outlet. When the furnace is operating, the hot exhaust passes through the heat extractor on its way to the chimney outlet. Within the return air duct there is a heat exchange from the heat extractor to the return cool air, thereby preheating the cool air just before it enters the furnace causing less consumption of energy to heat that air while the carbon monoxide harmlessly passes through the chimney outlet.

Methods and apparatus for heating air with hot water

A method controls an air handler that generates heated air from hot water generated by a water heater. The method includes generating a signal in the presence or absence of an indicia of water flow associated with the water heater; initiating operation of a pump associated with the air handler when the signal indicates that water flow associated with the water heater is at least at a selected level to supply hot water to the air handler sufficient to generate heated air; and/or terminating operation of the pump and/or a blower/fan associated with the air handler when the presence or absence signal indicates that the water flow associated with the water heater is less than the selected level.

HVAC SYSTEM PROGNOSTICS AND DIAGNOSTICS BASED ON TEMPERATURE RISE OR DROP
20210396414 · 2021-12-23 ·

An HVAC system includes a heating element, a discharge air temperature sensor, and a return air temperature sensor. A controller of the HVAC system determines that the HVAC system has been operating in the heating mode for at least a predefined amount of time. The controller receives measurements of the discharge air temperature and the return air temperature. A temperature rise value is determined using the discharge air temperature and return air temperature. If the temperature rise value is less than a predefined minimum threshold value, the controller determines that a first fault of the HVAC system is detected and provides a corresponding alert. If the temperature rise value is greater than a predefined maximum threshold value, the controller determines that a second fault of the HVAC system is detected and provides a corresponding alert.
