During summer nights, the temperature is initially quite high. As time passes, the temperature starts dropping. Also, after a person falls asleep, the metabolic rate of one s body decreases. Thus, initially the fan/cooler needs to be run at full speed. As time passes, one has to get up again and again to adjust the speed of the fan or the cooler.The device presented here makes the fan run at full speed for a predetermined time. The speed is decreased to medium after some time, and to slow later on. After a period of about eight hours, the fan/ ....etc

Thermoelectric cooling uses the Peltier effect to create a heat flux between the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current. Such an instrument is also called a Peltier device, Peltier heat pump, solid state refrigerator, or thermoelectric cooler (TEC). It can be used either for heating or for cooling, although i ....etc

AUTOMATIC SPEED CONTROLLER FOR FANS AND COOLERS



INTRODUCTION

This is a device to control the speed of fan and coolers automatically. The
device presented here makes the fan run at a full speed for pre determined time. This
speed is decreased to medium after some time and to slow then onwards after a period

of 8 hours, the fan or cooler is switched off.

The circuit consist of IC1 (555 Timer IC) which is used as an astable multi

vibrator use ....etc

Thermoelectric coolers, also called thermoelectric modules or peltier coolers, are semiconductor-based electronic components that function as small heat pumps. On applying a low DC voltage to the thermoelectric module, heat moves through the module from one side to the other. One face of the module is therefore cooled, while the other face simultaneously heats up. This phenomenon may be reversed whereby a change in the polarity of the applied DC voltage will cause heat to be moved in the opposite direction. consequently, a thermoelectric module ....etc
