Simulation of Radiant Cooling Performance with Evaporative Cooling Sources

This project addresses three closely related and similarly complex questions: First, using currently available simulation software, what methods might be appropriate for comparing slabintegrated radiant cooling to more conventional alternatives, such that the results are sufficiently fair and comprehensive to support system selection and design? Second, what is the relative performance of repre...

Radiative sky cooling :

Radiative sky cooling reduces the temperature of a system by promoting heat exchange with the sky; its key advantage is that no input energy is required. We will review the origins of radiative sky cooling from ancient times to the modern day, and illustrate how the fundamental physics of radiative cooling calls for a combination of properties that may not occur in bulk materials. A detailed co...

Evaporative Cooling of Actuators for Humanoid Robots

Autonomous humanoid robots need high torque actuators to be able to walk and run. One problem in this context is the heat generated. In this paper we propose to use water evaporation to improve cooling of the motors. Simulations based on thermodynamic calculations as well as measurements on real actuators show that, under the assumption of the load of a soccer game, cooling can be considerably ...
