Energy conservation in domestic refrigerators by cooling compressor shell – A case study

open access: yesCase Studies in Thermal Engineering, 2017
Application of energy efficient compressors, air handling units (AHUs), condensers and evaporators of high effectiveness are the some of the measures towards energy conservation in refrigeration systems. Cooling of compressor shell with the defrost drips

Influence of cyclic frozen and defrost on mechanical properties of polytetrafluoroethylene (PTFE)-coated woven fabrics [PDF]

open access: yesArchives of Civil Engineering, 2023
This research aims to determine the influence of the cyclic process of freezing and defrosting on the mechanical properties of the chosen glass fibres and PTFE-coated woven fabrics.

Investigation and Simulation of Air-source Heat Pump During Reverse Cycle Defrost

open access: yesZhileng xuebao, 2003
The recent research development on the hot-gas defrost for air-source heat pumps was reviewed. An ideal defrost model was presented based on the fundamental conservation equations and experimental results.

Freeze to defrost! Negating the asset form

open access: yesFinance and Society, 2023
Assets thrive on liquidity but they also enact a freezing of their own, a freezing of the underlying. How can we undo the cold reign of the asset economy?

PSpectRe: A Pseudo-Spectral Code for (P)reheating

open access: yes, 2010
PSpectRe is a C++ program that uses Fourier-space pseudo-spectral methods to evolve interacting scalar fields in an expanding universe. PSpectRe is optimized for the analysis of parametric resonance in the post-inflationary universe, and provides an ...

DEFROST: A New Code for Simulating Preheating after Inflation

open access: yes, 2008
At the end of inflation, dynamical instability can rapidly deposit the energy of homogeneous cold inflaton into excitations of other fields. This process, known as preheating, is rather violent, inhomogeneous and non-linear, and has to be studied ...

Enhancement of the Melting of an Ice Cylinder by the Combination with the Condensation of a Saturated Steam Flow

open access: yesJournal of Thermal Science and Technology, 2011
Melting of an ice by a steam is sometimes employed, for example, to remove a frost, an ice, and a snow that adhered to the structure surface. It is usually regarded that the melting performance by steam is naturally higher than that by high-temperature ...

Data-Driven Defrost-on-Demand Scheduling in Reefer Ships: A Predictive Maintenance Framework Using Real-World Sensor Data

open access: yesJournal of Marine Science and Engineering
Defrost cycles in shipboard refrigeration plants are typically initiated on fixed schedules or by operator judgement, which can lead to unnecessary energy use and temperature variability during the transport of frozen products. This study proposes a data-

Moisture transport processes and control of relative humidity in refrigerated facilities : a thesis presented in partial fulfilment of the requirements for the degree of Master of Engineering at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2007
Increasingly air relative humidity (RH) is becoming an important design and operational variable for refrigerated facilities. An integrated dynamic model of the main heat and moisture transfer mechanism in a refrigerated facility was developed.
