Abstract: Disclosed is a novel intelligent adjustable passive roof, comprising an inner roof layer, an air layer, a thermal diode of jumping droplet materials and an outer roof layer which are sequentially arranged from bottom to top. The thermal diode of jumping droplet materials comprises a super-hydrophilic layer, a super-hydrophilic layer surface liquid-absorbing core and a super-hydrophobic layer which are sequentially arranged from bottom to top, and the super-hydrophilic layer is separated from the super-hydrophobic layer by gasket materials on left and right sides to form an intermediate air interlayer. By means of passive heat transfer control of the super-hydrophilic layer and the super-hydrophobic layer in the thermal diode of jumping droplet materials, a novel intelligent adjustable passive roof, which is driven passively by indoor and outdoor temperatures for “heat extraction/heat insulation,” does not need to be manually cleaned, and can be embedded into a building enclosure structure, is formed.

Abstract: The present disclosure provides a monitoring, tracing, early-warning and control system and method for virus spreading in a building. Indoor and outdoor environmental parameters of the building can be monitored in real time. Human physiological indexes are obtained in real time to determine a human health state, and moving trajectories of people and droplet spreading trajectories are obtained. Therefore, suspected infected persons and their close contacts are timely and accurately identified, and countermeasures are taken for the suspected infected persons and the close contacts. In addition, a spreading risk in a current indoor environment can be assessed, the indoor environment is ventilated and purified according to a spreading risk assessment result, and local areas of the suspected infected persons and the close contacts are effectively ventilated and purified, so as to reduce the spreading risk.

Abstract: A convection/radiation air conditioning terminal and an air conditioning system are provided. The convection/radiation air conditioning terminal includes a heat pipe. One end of the heat pipe is connected to a first heat exchange pipeline, and the other end of the heat pipe is connected to a second heat exchange pipeline. The heat pipe includes multiple first microchannels which are arranged and independent of each other, and multiple second microchannels which are arranged and independent of each other, where the first microchannels and the second microchannels are arranged and independent of each other. The first microchannels are each internally provided with a first heat exchange working medium, and the second microchannels are each internally provided with a second heat exchange working medium.

Abstract: A tank container for transporting and storing liquefied gas, including a tank that includes a cylinder body and two heads arranged oppositely and welded with both ends of the cylinder body; and a frame assembly for fixing and supporting said tank, which includes a front frame and a rear frame fixed at both ends of said tank respectively. The cylinder body has a shell thickness ? substantially equal to: Pc×Di/(2?b/Ks?Pc), wherein, Pc is the calculated pressure of the tank, required by the transported liquefied gas, Di is the inner diameter of the cylinder body, ?b is the maximum tensile strength of material of the cylinder body at a normal temperature, and Ks is a safety factor no larger than 2.6. The tank container is designed through stress analysis methods, the safeness of which has been verified.
