Innovation is the HVAC field - Thermoelectric cooling components

The technology has since been used to cool temperatures of devices by creating heat sinks for different electronic materials. The most recent applications of this type of technology are the “wristify” cooling system invented by four MIT students. The “wristify” is used for maintaining the body temperature at a personal level. This they managed through the use of two different conductors and a very small battery. In order for the cooling to take place, the then a DC current is applied so as to initiate the movement of electrons. The efficiency in thermo-electric cooling, depends on materials be selected keenly. Many thermo-electric coolers made today are from an alloy of Bismuth Telluride (Bi2Te3). Thermo-electric cooling poses very advantages like lack of mechanical maintenance and ability to be used in very small places. The technology has a place in the future since there is a possible use of the technology in marine engineering of submarines, night vision and many more others.
Prototype wearable 'air-conditioning' device
According to fox news, In the MIT, four engineering students have been able to develop a wrist worn body cooling device that is based upon the Peltier Effect and theory. The device code named wristify employs a series of two different conductors that are referred to as the Peltier cooler. The device is powered a very small battery and then attached to a wrist wrap so as to hold it in place. For the device to reduce the body temperature, it starts by reducing the wrist temperature in degree fractions every second for a specified time period. However, the students have not arrived at the correct time calculations, but they say that a reasonable cooling effect is achieved when the wrist is cooled by 0.4 degrees Celsius for five seconds. After this session, the device goes off for 10 seconds and maintains the interval. However, the four students are still on the process of calculating for optimal timings so as to perfect the device. The Wristify is one of the major breakthrough in human attempt to thermo-electric cooling (Balmer, 2011). With this device, a different person will be able to customize their own temperature ranges without affecting others. This is an aspect that many will appreciate. This rate of success is a sign that with the rise in advance technology and availability of resources, thermo-electric cooling can be utilized in areas that people had never imagined before. Thermo-electric cooling Definition Thermo-electric cooling refers to an application of the Peltier Effect to create a difference in temperature between two materials of different type. A thermo-electric cooler is usually a solid stated active that is able to transfer heat from one side of a device to the other. This is possible based on the following physical theories. First, when two different conductors are under electric contact, there is an electron flow out of the conductor that is less bound into the other conductor in which electrons are more. This is possible because of the difference in Fermi level between the two devices used as conductors. The Fermi level shows the difference in energy levels that are contained in different conductors occupied by electrons, and those that are not occupied. Therefore, when two conductors of different Fermi levels. This can be easily compared to diffusion in which molecules move from an area of high concentration to that of low concentration. How it works In order for the cooling to take ...Show more

Summary

Thermo-electric cooling systems are some of the most efficient cooling systems that manage to remain simple and applicable in many fields of electronics (Pickard, 2011). …
