Method and apparatus for controlling ventilation systems

An energy recovery ventilation system is described which allows for continuous fan speed control through pulse width modulation of direct current fans. The energy recovery ventilation described is capable of fine motor speed control without the disadvantages of high noise, low efficiency and a fixed number of speeds present in commonly-used speed-varying techniques used with alternating current (AC) fans. This may be accomplished through the use of direct current (DC) fans and pulse width modulation. A controller is used to optimize the ventilation and energy efficiency of the system through the use of several temperature sensors. The energy recovery ventilation also provides a control process for self-optimization of the energy recovery ventilation, in case the supply and exhaust airflows are unequal. An unbalance may be detected by calculating the thermal efficiencies of the exhaust and supply airflows.

Control apparatus for internal combustion engine

ActiveUS20150377164A1Efficiency of internal can be restrained deterioratingMaintain thermal efficiencyHybrid vehiclesElectrical controlOperating pointExternal combustion engine
A control apparatus for an internal combustion engine is provided. The control apparatus includes an ECU. The ECU is configured to change, in a stepped manner, an air-fuel ratio of the internal combustion engine so as to change over a combustion mode of the internal combustion engine between lean combustion and stoichiometric combustion, when an operating point of the internal combustion engine satisfies a first changeover condition that is defined by a rotational speed and a torque of the internal combustion engine. The first changeover condition is defined by the rotational speed and the torque that correspond to a predetermined intake air amount at which a thermal efficiency of the internal combustion engine is maintained before and after changeover of the combustion mode.

LED with ceramic green phosphor and protected red phosphor layer

A ceramic green wavelength conversion element (120) is coated with a red wavelength conversion material (330) and placed above a blue light emitting element (110) such that the ceramic element (120) is attached to the light emitting element (110), thereby providing an efficient thermal coupling from the red and green converters (330, 120) to the light emitting element (110) and its associated heat sink. To protect the red converter coating (330) from the effects of subsequent processes, a sacrificial clear coating (340) is created above the red converter element (330). This clear coating (340) may be provided as a discrete layer of clear material, or it may be produced by allowing the red converters to settle to the bottom of its suspension material, thereby forming a converter-free upper layer that can be subjected to the subsequent fabrication processes.

Method for smelting lead-bismuth concentrate in oxygen-rich side-blown duplex furnace

The invention discloses a method for smelting a lead-bismuth concentrate in an oxygen-rich side-blown duplex furnace, belonging to the technical field of smelting bismuth concentrates. The method comprises the steps of preparing raw materials, and smelting in the oxygen-rich side-blown oxidation-reduction duplex furnace to directly produce a crude bismuth alloy. According to the method, scrap iron is not required to be added, so that the production cost is low; the concentration of SO2 in flue gases generated from oxidizing smelting reaches 10 to 25 percent, and the SO2 can be recycled to prepare acid, so that the problem of environmental pollution caused by the flue gases is solved; and the oxidation-reduction duplex smelting ensures that the direct yield of bismuth is greatly promoted.
