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: 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.
