The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 2.3 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.2 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00037 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.6 SJR: 0.433 SNIP: 0.593 CiteScore™:: 4.3 H-Index: 35

RÉSUMÉ

This paper provides an evaluation of the potential for use of brazed aluminum condensers in residential air-conditioning systems. Analysis was done to compare the performance of a brazed aluminum condenser with a presently used 2-row finned tube condenser having 7.0 mm diameter tubes. The comparisons were made for 1-row brazed aluminum designs using 3 × 16 mm or 2 × 20 mm cross-section tubes, whose condensing performance has been measured. Used with a commercially available fin geometry at 26 fins/in, the 3 × 16mm tube design will provide 35% material weight reduction and 15% lower pressure drop, relative to the 7.0 mm round-tube heat exchanger. No cost reduction is predicted. The predicted air-side performance was verified in wind tunnel tests. An advanced fin design having a smaller louver pitch will use 22 fins/in, and provide a 55% material cost reduction. The advanced fin geometry has 8.1 mm high fins, 12 louvers and 1.0mm louver pitch. If a tube having 2.0 mm minor diameter is used, greater air pressure drop reduction will be achieved, but at the expense of material savings.
