A low power, eco-friendly multipurpose thermoelectric refrigerator

N. Jagan Mohan REDDY

Frontiers in Energy 2016, Volume 10, Issue 1, Pages 79-87 doi: 10.1007/s11708-015-0380-8

Abstract: There has been an immense endeavor to mitigate global warming in spite of which it has only been worse. This paper presents the design and implementation of a low power and eco-friendly refrigeration system using the thermoelectric effect. The conventional refrigerators make use of complex mechanisms which involves synchronous operation of various units, namely the compressor, condensers, expansion valves, evaporator, refrigerant and so on. But a thermoelectric refrigerator exploits the principle of the Peltier effect, thus avoiding the utilization of these complex components. This even helps curb the release of harmful chlorofluorocarbons (CFCs) into the atmosphere which contributes to the increase in global temperature. Moreover, the temperature can be controlled and set to required values with the help of a microcontroller. Hence, this can be used both for domestic and commercial purposes. The unit does not eject any harmful gases. Therefore, the heat expelled from the unit can be tapped for heating utilities, making the use of this device versatile in its application. Thus this proposal aims not only at reducing the air pollutants by not contributing to it but also at reducing the power consumption.

Controller area network node reliability assessment based on observable node information Article

Lei-ming ZHANG, Long-hao TANG, Yong LEI

Frontiers of Information Technology & Electronic Engineering 2017, Volume 18, Issue 5, Pages 615-626 doi: 10.1631/FITEE.1601029

Abstract: The method estimates the transmit error counter (TEC) of any node in the network based on the networkFirst, a node TEC estimation model is established based on segmented Markov chains.Then, this estimation updating mechanism is transferred to general CAN nodes with no TEC value accessibilityto update the TEC estimation.
