Seminar 59 -- Performance of Low GWP Refrigerants in Plate Heat Exchangers

This product is a zip file that contains files that consist of PowerPoint slides synchronized with the audio-recording of the speaker, PDF files of the slides, and audio only (mp3 format) as noted.

Plate heat exchangers are extensively adopted in HAVC systems due to their smaller footprint, limited refrigerant charge, higher efficiency, and lower cost. This seminar will highlight the experimental and theoretical work on condensation and boiling of low GWP refrigerants inside a plate heat exchanger. It will provide heat transfer and fluid flow analysis by comparing the two conventional prediction approaches. Moreover, the effect of various parameters such as fouling, corrosion, and particle aggregation on the extended performance of a plate heat exchanger will be discussed. Lastly, a comprehensive performance correlation for plate heat exchangers will be presented.
