    摘要: The present invention discloses anon-power driven window capable of adjusting ventilation rate. When the sash is unlocked, due to combined action of the sash's gravitational torque and the expansion of a torsion spring against the sash, the window keeps open. The window is designed having a bigger size in the lower section below the pivot than that in the upper section. Subject to the outdoor wind blowing, the moment by the outdoor wind tends to shut the window. In addition, the upper screen is installed in the outer side of the pane above the pivot, while lower screen is installed to the inner side of the pane below the pivot. Thus the lower sash is exposed into the outdoor air and can be easily blown by the outdoor wind. Consequently, the stronger is the outdoor wind, the smaller is the effective opening of the window for ventilation, and vice versa.

    摘要: This invention addressed a method for measuring the foreign substance content invaded into a thin plate porous material based on the principle of virtual heat sources. The technical points of the invention are: (1) using the principle of virtual heat sources to improve the traditional heat pulse method to measure the foreign substance content; (2) representing the heat transfer effect on boundaries of the thin plate porous material by establishing an infinite number of virtual heat sources with two different heat intensities; (3) obtaining the volumetric heat capacity of the test material together with the invaded foreign substance content based on the four-parameter search to obtain the best temperature match between the measurement and the solution. Unlike the existent methods, there is no specific requirement on the domain size of the test materials and the heat transfer boundary conditions, which makes the measurement of the foreign substance content into the plate-shape test material with a finite thickness more readily.

    摘要: The present invention relates to a disinfection device of door handle being rotational and transpositional, the composition is as follows: a plurality of door handles are provided, which are respectively in the states of “to be used”, “in disinfection”, “in disinfection post-treatment” and/or “in ready”; and the door handle transposition shaft is driven by the rotary driving device of door handle transposition shaft to rotate counterclockwise, thus to complete synchronous rotation of the door handles and realize transposition operation. The use, disinfection and disinfection post-treatment of the door handles of the present invention are carried out synchronously, which can meet the requirements of immediate use of the door handles and safety to the users; the transposition of the door handles is implemented by the pure mechanical driving device; the door handles automatically rotates for transposition after a door opening and closing, therefore “disinfection after each use” is realized.

    摘要: A radiant air conditioning system for controlling comfortable and healthy indoor environment based on infrared sensing technology is disclosed, which comprises air source heat pump outdoor unit, plate evaporator, circulating water pump, etc. Accurate control of air humidity by installing an indoor dehumidification terminal can reduce the surface temperature of radiant cooling terminal and increase the installed area, which will significantly improve the radiant heat exchange between the terminal surface and the human body surface. Infrared sensor technology, which is adopted to obtain the number of indoor occupants and the required outdoor air flow rate, is integrated with a decoupling control of the indoor humidity and air freshness for the accurate control of outdoor air flow rate, and then the supply outdoor air temperature and humidity are regulated for the accurate control of indoor health level.
