摘要:
A device includes a setting unit setting a control target value for setting an activation, an operation, and a deactivation at a next day for control-target devices including an energy supplying device, an energy consuming device consuming energy, and an energy storage device storing energy, a predicting unit that sets a predicted value of the consumed energy of the energy consuming device at the next day based on a comparison between the control setting value set by the setting unit and a past control setting value, a start-stop optimizing unit that creates a start-stop schedule obtained by optimizing the start-stop schedule of the control-target device at the next day by an evaluation index, and a status-quantity optimizing unit that creates an electric/thermal energy storing schedule obtained by optimizing the status quantity of the control-target device to be activated by a predetermined evaluation index.

The invention relates to a steam generator (1) for a Rankine process, in particular for a waste-heat utilization device (37) of an internal combustion engine (36), preferably in a motor vehicle, comprising: a heat exchanger duct (2) in which a heat exchanger (3) is arranged, and a bypass duct (4) for bypassing the heat exchanger duct (2), wherein the heat exchanger duct (2) and the bypass duct (4) can, during operation of the steam generator (1), be traversed by a flow of a heating fluid, and wherein the heat exchanger (3) can, during operation of the steam generator (1), be traversed by a flow of a medium (47) to be evaporated. A compact design with high energy efficiency can be attained if the heat exchanger duct (2) encases the bypass duct (4).
摘要:
Liquid is flash evaporated in a series of cells along and surrounding an exhaust duct to generate a pressurized vapor where at least one of the surfaces is in communication with the source of heat sufficient to maintain the surface at a temperature such that the liquid injected into the chamber is substantially instantly converted to a superheated vapor with no liquid pooling within the chamber. The liquid is introduced by controlled injectors operating at a required rate. Each of the cells is periodically discharged by a pressure controlled relief valve and the vapor from the cells combined to form a continuous stream feeding a turbine or other energy conversion device. The outer wall of the cell is offset so that it contacts the inner wall at one point around the periphery. Heat transfer ribs and bars can be provided in the duct to provide increased heat transfer where necessary.

In a waste-heat recovery system, a gear pump and an electric motor share a drive shaft. A pump interior portion and a motor interior portion are partitioned from each other by a shaft seal, and the pump interior portion defines a part of a circulation path of a Rankine cycle circuit. One end of a communication path that is communicated to the motor interior portion is connected to a bottom portion of a housing, and the other end of the communication path is connected to the circulation path at a position between an expander and a condenser in the Rankine cycle circuit.

In a power supply system (10) having a cogeneration unit (12) equipped with an internal combustion engine (12a) and a generator (12b) to generate power to be supplied to a power destination and hot water to be supplied to a hot water destination, there are provided with a natural energy generation unit (14) that generates power with natural energy, a power supply unit (20) that receives the power generated by the generator and natural energy generation unit to supply the received power to the power destination; a voltage detector (22a) that detects voltage (V1) of the power flowing through an connecting bus (22), and an electric heater (121). The power supply unit (20) controls operation of the electric heater based on the detected connecting bus power voltage (V1), thereby effectively utilizing surplus electricity without transmitting back it to a commercial power source.
