Optimal refrigerator [PDF]

open access: yesPhysical Review E, 2010
We study a refrigerator model which consists of two $n$-level systems interacting via a pulsed external field. Each system couples to its own thermal bath at temperatures $T_h$ and $T_c$, respectively ($\theta\equiv T_c ...

A Comparative Experimental Study Analysis of Solar Based Thermoelectric Refrigerator Using Different Hot Side Heat Sink [PDF]

open access: yesEngineering and Technology Journal, 2022
The heat sink influences heat dissipation at the hot junction of the Peltier module and, hence, affects the performance of the thermoelectric refrigerator.

Performance analysis of a retrofitted refrigerator using eco-friendly refrigerant [PDF]

open access: yesThe Holistic Approach to Environment, 2023
The use of refrigerants with a global warming potential (GWP) greater than 150 is banned in small and medium-sized refrigerators in accordance with the European F-Gas policy. Therefore, the suitability of retrofitting an existing refrigerator using a low

Quantum Advantage of Thermal Machines with Bose and Fermi Gases

open access: yesEntropy, 2023
In this article, we show that a quantum gas, a collection of massive, non-interacting, indistinguishable quantum particles, can be realized as a thermodynamic machine as an artifact of energy quantization and, hence, bears no classical analog.

Measurement-Based Quantum Thermal Machines with Feedback Control

open access: yesEntropy, 2023
We investigated coupled-qubit-based thermal machines powered by quantum measurements and feedback. We considered two different versions of the machine: (1) a quantum Maxwell’s demon, where the coupled-qubit system is connected to a detachable single ...

Brownian Refrigerator [PDF]

open access: yesPhysical Review Letters, 2006
Onsager symmetry implies that a Brownian motor, driven by a temperature gradient, will also perform a refrigerator function upon loading. We analytically calculate the corresponding heat flux for an exactly solvable microscopic model and compare it with molecular dynamics simulations.
