Microwave Blood Plasma Defroster
Journal of Microwave Power and Electromagnetic Energy, 1991A microwave blood plasma defroster capable of thawing up to four bags of frozen blood plasma at a time is described. The unit stops automatically when the plasma reaches a preset temperature, and all operating parameters are monitored for safety. Comparative testing showed that blood plasma thawed in this device was indistinguishable from plasma thawed

Study on the Liquid Refrigerant Defrosting System and the Defrosting Rule
Journal of Thermal Science and Engineering Applications, 2018The liquid refrigerant defrosting (LRD) is a defrosting method which leads the liquid refrigerant in the high-pressure reservoir to the frosting evaporator. The refrigeration process is continuous during the defrosting period, which increases the defrosting frequency.

Vehicle Defroster System Evaluation
SAE Technical Paper Series, 2000<div class="section abstract"><div class="htmlview paragraph">Vehicle defrost systems are required to defrost the windshield and side windows in a short period. This portion of the HVAC system is not only required to work without interfering with operator comfort relating to high temperatures being felt by the drivers face, but also ...

Renewable and Sustainable Energy Reviews, 2017
Abstract This study reviewed the defrosting techniques applicable for the heating, ventilation, air-conditioning, and refrigeration industry, including passive, active, and system techniques. The passive methods normally use treated surfaces by changing the surface morphology through micro-grooved, anti-frost coating, hydrophilic, hydrophilic, or ...

Defrosting instructions: A response
Cambridge Opera Journal, 2004The title of this issue, ‘Performance Studies and Opera’, optimistically announces a conjunction between two disciplines that have previously had surprisingly little to do with each other, despite substantial common ground. The three articles gathered here, however, bear marks both of the excitement sparked by the novelty of bringing the methods of ...

The differential equations describing heat and mass transfer during each stage of defrost are solved, and results are compared to measurement. Numerical solutions for defrost Stages I and II are obtained, while an analytical solution for Stage III is possible. For Stage I, the duration of the stage is predicted and validated by experiment. For Stage II,

A comprehensive one-dimensional model is developed for heat and mass transfer in each stage of the defrost process. The model describes sublimation, vapor transport, liquid melting and evaporation on a heated vertical surface in each of three distinct stages of the defrost process: diffusion, melting-permeation and dry out.

Coke and Chemistry, 2014
In cold climates, there is great interest in restore the friability of frozen material and to prevent the material from freezing in the first place. Coke plants often employ methods based on heating frozen coal by means of some hot material, but that approach has several shortcomings. A new method based on electromagnetic energy is proposed.
