Steam compression with inner evaporative spray cooling: a case study

An adiabatic dry saturated steam compression process with inner evaporative spray cooling in screw compressors for steam heat pump systems is studied. Thermodynamic model and simulation of this variable-mass compression process are devised. Differential equations are formulated and used to calculate the amount of liquid injected and the work to drive the compressor on the basis of simplificatio...

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...

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 ...
