Full Description
Track: Heat Exchange Equipment
Sponsor: 8.4 Air-to-Refrigerant Heat Transfer Equipment
Chair: Chad Bowers, Ph.D., Associate Member, Ingersoll Rand, Clarksville, TN
Air-side corrosion continues to be a topic of much interest in the industry. Specifically understanding how to standardize on accelerated testing and combat corrosion with appropriate designs. Updates of ongoing ASHRAE research and advances in the understanding of the nature and causes of corrosion in air to refrigerant corrosion are presented by industry experts and those conducting the research.
1. Cyclic Polarization of AA 3102 in Various Corrosive Electrolytes
Seifollah Nasrazadani, Member, University of North Texas, Denton, TX
This presentation evaluates whether cyclic polarization can be used to assess corrosion resistance of AA 3102 in corrosive environments and if corrosion potential can be used as a measure of AA3102 performance in corrosive environments.
2. Field Test Data and Comparison to Accelerated Corrosion Lab Tests for Different Mchx Solutions.
Claudi Martn Callizo, Ph.D., Associate Member, Granges Aluminium (Shanghai) Co. Ltd, Shanghai, China
This presentation shows corrosion performance data of different MCHX system solutions from several field test sites with distinct atmospheric environments; compares these results with data from accelerated cabinet tests from the lab; and explains the corrosion mechanisms and corrosion sequence of different MCHX systems.
3. Aluminum Round Tube: Application Requirements and Corrosion Performance
Vikas Somani, Brazeway, Adrian, MI
This presentation discusses aluminum round tube applications and requirements as well as corrosion rate and behavior of 3xxx series alloy under different corrosion tests.
Presented: Tuesday, January 23, 2018, 8:00-9:30 AM
