BENIFITS OF SOLAR REFRIGRATOR OVER NORMAL REFRIGERATOR • While refrigerators and air conditioners utilize compressors, condensers, and liquid refrigerants to lower temperature; solid-state cooling utilizes DC power, heat sinks, and semiconductors. This fundamental difference gives solid-state thermoelectric coolers the following advantages over compressors: • No moving parts. Therefore they require little or no maintenance. Ideal for cooling parts that may be sensitive to mechanical vibration. • No refrigerants, such as potentially harmful CFCs. Therefore environmental and safety benefits. • Enables reduced, low-noise operation of cooling fans, while providing greater cooling power. • Suitable for manufacture in very small sizes. Therefore ideal for microelectronics. • Lightweight. • Long life. Exceeds 100000 hrs MTBF (Mean Time Between Failures). • Controllable (by voltage / current). • Small size. • Fast, dynamic response. • Enhanced ration between heat sink and target element. • Can provide cooling below ambient temperature. Thermoelectric coolers (TECs), also known as Peltier coolers, are solid-state heat pumps that utilize the Peltier effect to move heat. Passing a current though a TEC transfers heat from one side to the other, typically producing a heat differential of around 40°C—or as much as 70°C in high-end devices—that can be used to transfer heat from one place to another. APPLICATION OF PROJECTS; • For military Purpose where fast and compact cooling required ...
