Abstract:
This invention provides a system and method for cogeneration of electric power and building heat that efficiently interfaces a liquid-cooled electric power generator with a multi-zone forced water (hydronic) space heating system. The system and method utilizes an electric generator with an electric output capacity (kW) that is near the time-averaged electric power consumption rate for the building and with a heat generation capacity that is useful for meeting building heating needs. This generator is operated as the priority source of heat for the building, but normally only when there is a demand for heat in building, with the intent of running the generator for long periods of time and generating a total amount of electric energy (kW) that is significant in comparison to the total electric energy consumption of the building over time. The actual onsite time-variable power demand (kW) is met by a combination of the congenerated electric power produced on site and quantities of electric power from the public electric power grid or another external power source. Hence, useful electric power is generated on site as a byproduct of the required generation of heat for space or water heating. The generator is run at a speed/operating condition that is appropriate to maintaining a long operational life.

Abstract:
A water production, heating supply, air conding and electric power generation system consists of a low temperature pressure generator unit, a cryogenerator unit, a producing water unit, a cryogenically produced nitrogen unit and a heating unit which are connected by pipelines. While producing water by condensing air with a low temperature refrigerating apparatus, the system supplies heating and air-conditioning, and generates electricity. Since using closed-circuit, there is no energy cost while operating.
Abstract:
Existing approaches to refuse handling are all based on historical approaches which rely on a network of refuse collection vehicles collecting waste from individual households and delivering this to a centralised landfill or MBI location. This is highly undesirable and wasteful. An alternative process is disclosed, relying on the thermal treatment of waste and like products produced or brought in to the residential property and processed within the domestic curtilage to produce fuel or other forms of energy. Thus, domestic waste will be thermally treated at the home instead of being collected by local authorities and disposed of. The waste input material will be loaded into a domestically engineered thermal conversion unit either directly or after a pre-process such as shredding. The feedstock will be converted into fuels by a thermal treatment, such as pyrolysis. The resultant output of oil and gas can either be stored or fed into a boiler unit to be used as a fuel to produce hot water, or used to run an electricity generating unit to power the dwelling in question or for supply to a feed-in tariff. Thus, a domestic dwelling includes a thermal treatment unit for processing waste produced in the dwelling, an output of the thermal treatment unit being combusted for producing an energy output for the dwelling. A suitable pyrolysis chamber is disclosed.
Abstract:
The invention relates to a coupling system (100) for a hybrid energy installation comprising a heat pump apparatus (110) and a force/heat coupling apparatus (120) with at least one coupling device (130) for coupling the heat pump apparatus (110) and the force/heat coupling apparatus (120). The object of the invention is to provide an apparatus and a method which implements coupling for a heat pump apparatus (110) and a force/heat coupling apparatus (120), wherein in comparison with previously known, uncoupled installations, a total efficiency which is as high as possible and a consumption of resources which is as low as possible are ensured. The invention is characterized in that the at least one coupling device (130) has an electrical coupling unit and/or a hydraulic coupling unit, which are configured so as to be switchable for a coupling of the heat pump apparatus (110) and the force/heat coupling apparatus (120). Furthermore, the invention relates to an energy transformation system for producing heat and/or cold and a method for energy transformation with a coupling system (100).
