Image-Analysis-Based Approach for Identification of Air Cooler Heat Transfer Degradation during Frosting Process

Autor: Paweł Jakończuk, Dariusz Butrymowicz, Kamil Smierciew, Jerzy Gagan

Publikováno v: Sustainability; Volume 14; Issue 21; Pages: 13731

Fin-and-tube heat exchangers have been extensively used in many fields, especially in heat, ventilation, air-conditioning, and refrigeration systems. In the case of the operation of a fin-and-tube heat exchanger as an air cooler, frost formation is a

Temperature drop of heating fluid as a primary condition for effective utilization of low-grade heat using flash cycles and zeotropic mixtures in refrigeration ejector systems

Autor: Huiming Zou, Paweł Jakończuk, Kamil Śmierciew, Dariusz Butrymowicz, Adam Dudar

Publikováno v: Energy Sources, Part A: Recovery, Utilization, and Environmental Effects. :1-19

The conventional refrigeration ejector cycle utilizes a constant temperature process during motive heat consumption needed for vapor generation. This may be thought of as the main restriction conce...
