Thermoelectric efficiency of three-terminal quantum thermal machines [PDF]

open access: yes, 2014
The efficiency of a thermal engine working in linear response regime in a multi-terminals configuration is discussed. For the generic three-terminal case, we provide a general definition of local and non-local transport coefficients: electrical and ...

Bounds on thermal efficiency from inference [PDF]

open access: yesAIP Conference Proceedings, 2015
The problem of inference is applied to the process of work extraction from two constant heat capacity reservoirs, when the thermodynamic coordinates of the process are not fully specified. The information that is lacking, includes both the specific value of a temperature as well as the label of the reservoir to which it is assigned.

Influence of usage and model inaccuracies on the performance of smart hot water heaters: lessons learned from a demand response field test

open access: yesFrontiers in Energy Research
Domestic hot water heaters are considered to be easily integrated as flexible loads for demand response. While literature grows on reproducible simulation and lab tests, real-world implementation in field tests considering state estimation and demand ...
