The thermoelectric refrigeration system is an application of the Peltier effect, and good performance dependent on effective heat dissipation performance. To enhance cooling system, this paper designs a new type finned sink, which does not change overall size system. under fin tested by experiments various conditions. During experiment, wind speed, temperature hot cold side TEC, power consumpti...

Fuzzy logic controls and neuro-fuzzy controls are accustomed to increase the performance of air conditioning system. In this paper, we are trying to provide the new design air conditioning system by exploitation two logics, namely fuzzy logic and neuro-fuzzy management. This paper proposes a set of rule and uses 2 inputs specifically temperature and humidness and 4 outputs specifically compress...

In this paper, a new simulink model for a single phase induction motor is proposed using double field revolving theory. To maintain a constant fluid flow with a variation in the pressure head, drives like Fan load and Pump load are operated with closed loop speed control. For non linear loads, closed loop speed control is achieved using a neural network controller. A comparative study has been ...

Forced draft evaporative cooling towers are often used for condenser cooling in small steam power plants. Conventional control strategies keep the cooling pump operating at full speed all the time, and control the cooling water temperature by modulating the tower fan speed. In this work, an energy-efficient control strategy is proposed, that minimizes the combined consumption of the tower fans ...

We model and compare on-chip (up to wafer scale) and off-chip(multichip module) high-speed electrical interconnections withfree-space optical interconnections in terms of speed performance andenergy requirements for digital transmission in large-scalesystems. For all technologies the interconnections are firstmodeled and optimized for minimum delay as functions of theinterconnection length for ...

This paper presents an overview of the characteristics potentially influencing profile vortex shedding (PVS) phenomenon being relevant in noise and vibration low-speed axial fan rotor blades. Dimensional analysis has been applied to explore essential dimensionless quantities a systematic comprehensive manner. On this basis, limitations have established, simplifying assumptions set up terms PVS ...

Single Phase AC motors continue to be the primary solution for air-movement, pumping and compressor applications. Their low cost and availability make them ideal for lowperformance systems. DC Brushless platforms attempt to address these applications but their higher cost and complexity continue to form impenetrable barriers of entry. They are viewed as overkill for most applications. Single-Ph...
