Green Material Prospects for Passive Evaporative Cooling Systems: Geopolymers
Passive cooling techniques have been used mostly in countries with hot and arid climates such as Iran, Egypt, and India. However, the use of this important technology has not been seriously considered until a time of energy crisis, and consequently, environmental crisis scenarios, emerge. Scholars have renewed their interest in investigating passive cooling technology, particularly the aspects ...
متن کاملEvaporative 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 ...
متن کاملAn analytical model for evaporative cooling
We have developed an analytical model for evaporative cooling [1]. By simulating evaporation as a sequence of discrete steps, we could predict the time dependence of all important parameters such as temperature, density, elastic collision rate. By incorporating trap loss due to background gas collisions into our model we derived the threshold conditions for “run-away” evaporation. This is chara...

متن کاملGreen Practices Of Air Conditioning For Major Capital Cities Of India Using Advanced Evaporative Cooling
In the present era of energy crisis, effective and energy efficient air conditioning is a need of time. Advanced evaporative cooling is able to replace conventional air conditioning. This paper identifies the major cities of India and investigates scope and potential of evaporative cooling over entire period of year using feasibility index method. Initially paper describes basic and advanced me...
