Machine learning for filter pollution control [PDF]

open access: yesMATEC Web of Conferences, 2020
Modern buildings usually have an air-tight envelope. Therefore mechanical ventilation is very often necessary. A crucial part of the system is the filter, which allows creating an atmosphere that is free of dust, aerosols, and pollen. As organic material

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.

An Improved Gas Leakage Model and Research on the Leakage Field Strength Characteristics of R290 in Limited Space

open access: yesApplied Sciences, 2022
Some alternative refrigerants with excellent environmental performance often have different flammable limits. When refrigerant leaks, the external space may have a certain explosion risk if the refrigerant is not diffused timely.

Vapor pressure measurement of electrolyte solution and its impact on regeneration process in TRAB

open access: yesCase Studies in Thermal Engineering, 2022
As a rapidly developing heat-electricity conversion technology in recent years, thermally regenerative ammonia-based battery (TRAB) is characterized with the advantages of high power density and recyclability. Compared with the chemical reaction in TRAB,

Analysis on the optimal mixing pressure and efficiency limit of an ideal ejector

open access: yesEnergy Reports, 2021
Ejector is a component using high-pressure fluid to aspirate low-pressure fluid, whose potential in energy saving is increasingly emphasized. The upper limit of ejector performance is still an interesting and instructive issue.

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 ($ \equiv T_c/T_h<1$). The refrigerator functions in two steps: thermally isolated interaction between the systems driven by the external field and ...
