摘要:
An air heating device includes two closed conduits, one conduit for the flow of the air supply to a combustion furnace and the other for the flow of exhaust gas from a combustion furnace to a flue. The conduits pass through and around each other multiple times in an interweaving pattern such that the entirety of either conduit is almost completely surrounded by the other conduit, to maximize contact area and thermal energy transfer between the conduits relative to the device size and no use of small tubes or passageways. The shapes and pattern of the two conduits resembling the appearance of a sine wave and cosine wave drawn on the same x axis.

In a domestic energy supply system, the thermal energy of the temperature difference between at least one heat source and at least one heat sink is converted into work by way of a thermal engine. The thermal engine has a fluid cycle with at least two reservoirs, which, in each case as a condenser to be cooled or an evaporator to be heated, are thermally coupled to the heat source or the heat sink. A working temperature difference between the reservoirs of approximately 10° to 200° C. is set at a working temperature of 30° to 280° C. The thermal engine has a hybrid motor in the form of a combination of a pressure media motor and an internal combustion engine, in which firstly a pressure difference of the fluid as a result of the working temperature difference is used for driving purposes and secondly fuel is combusted and converted into work. Furthermore, the invention relates to a method for controlling such a system.

Invented is a method of making combustion air for a fossil fuel burner, as a coal burning power plant, oil refinery or gas fired household appliance. Combustion air is made from solar, wind, biomass, hydropower or geothermal. A staged progression using lower cost greenhouses, or flatplates, or solarponds, feed warm air to higher cost concentrator solar collectors. Wind energy, biomass, geothermal energy heat and compress combustion air. Hydropower also heats and compresses combustion air. Solar evaporation from salt or impure water creates water or local rain for the hydropower system. Combustion air thus is made economically hot, compressed and high velocity, and placed into a heavily insulated pipes for long distance transmission to a distant power plant.

The hot water supply apparatus includes a heat pump unit operating using electrical energy, a hot water storage tank storing hot water heated by the heat pump unit, and an auxiliary heat source device burning fuel and heating hot water when a stored hot water heat amount is insufficient for a heat amount used for hot water supply. A control device calculates a predicted heat amount for each unit time period based on a past usage record of hot water supply; estimates an error distribution of an actual heat amount relative to the predicted heat amount; calculates an expected value of loss in a target index using the estimated error distribution; obtains an optimal stored hot water heat amount minimizing the expected value; and controls the heat pump unit so that the hot water storage tank stores the optimal stored hot water heat amount.
摘要:
An auxiliary heating system includes a furnace positioned within a building. The furnace includes an outlet duct and a thermostat electrically coupled to the furnace. The thermostat establishes a trigger temperature. A housing is provided to contain a combustible material. A discharge is coupled to the housing and discharges smoke produced from combustion of the combustible material. A conduit is coupled between the housing and the outlet duct to direct heat into the outlet duct. A damper is positioned within the conduit to restrict a flow of the heat into the outlet duct. A control circuit is coupled to the housing and electrically coupled to the thermostat and a power source. A fan is positioned within the conduit and electrically coupled to the control circuit. The fan is actuated when a temperature in the building falls below the trigger temperature to urge the heat into the outlet duct.
摘要:
In the heat utilization installation (1) according to the invention several heat sources (2) are included which are provided each with a jet pump (16), (17), (18), (19). The heat sources (2) are connected to a heat carrier circuit system (7) which includes a single, central circulating pump or circulating pump unit (20). The individual jet pumps (16) to (19) are so controlled for the respective heat sources (2), the required operating temperatures with respect to temperature difference between the outlet and inlet and the flow volume are maintained or achieved. With the possibility of independent control of the flow volumes at the various heat sources (2), uniform fluid temperatures as required for a buffer store (22) or heat consumers can be maintained.
