41. Influence of Concentration and Additives on R123/Paraffinic Material Oil Boiling Heat Transfer Performance (NISTIR 7336)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7336
Published: 9/1/2006
Authors: Mark A Kedzierski, D H Han
Abstract: This paper investigates the effect that oil concentration had on the boiling performance of an R123/paraffinic mineral oil mixture on a roughened, horizontal flat surface. For all compositions, the lubricant caused a heat transfer degradation relati ...

42. Report of Phase One Measurement and Analysis of Building Water System Contamination and Decontamination
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7351
Published: 7/3/2006
Authors: Stephen J. Treado, Mark A Kedzierski, Stephanie S Watson, Dale P Bentz, Nicos Martys, Kenneth D Cole
Abstract: This report describes the results of the first phase of a research project to evaluate how contaminants accidentally or intentionally introduced into the water supply might accumulate in building plumbing systems, and how these contaminants might be ...

43. A Comparison of R245fa Pool Boiling Measurements to R123, and R245fa/Isopentane on a Passively Enhanced, Horizontal Surface
Published: 4/3/2006
Author: Mark A Kedzierski
Abstract: This study presents pool boiling heat transfer measurements for R245fa, R123 and a mixture of R245fa and isopentane on a flattened passively enhanced low-pressure boiling surface. Possibly because the enhanced surface was flattened from a round tube, ...

44. Horizontal Convective Boiling of Refrigerants and Refrigerant Mixtures Within a Micro-Fin Tube
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7243
Published: 7/1/2005
Authors: L J Hamilton, Mark A Kedzierski, M P Kaul
Abstract: This paper presents local convective boiling measurements in a micro-fin tube for four pure refrigerants: R22, R32, R125, and R134a; and four refrigerant mixtures: R410B (R32/125, 45/55 % mass), R32/R134a (28/72 % and 30/70% mass) and, R407C (R32/12 ...

45. Effect of Bulk Lubricant Concentration on the Excess Surface Density During R134a Pool Boiling with Extensive Measurement and Analysis Details
Series: NIST Interagency/Internal Report (NISTIR)
Published: 6/1/2005
Author: Mark A Kedzierski
Abstract: This paper investigates the effect that the bulk lubricant concentration has on the non-adiabatic lubricant excess surface density on a roughened, horizontal flat pool-boiling surface. Both pool boiling heat transfer data and lubricant excess surfac ...

Published: 1/21/2005
Author: Mark A Kedzierski
Abstract: This paper investigates the effect that the bulk lubricant concentration has on the non-adiabatic lubricant excess surface density on a roughened, horizontal flat pool-boiling surface. Both pool boiling heat transfer data and lubricant excess surface ...

48. Pressure Drop During Refrigerant Condensation Inside Horizontal Smooth, Helical Micro-Fin, and Herringbone Micro-Fin Tubes
Published: 10/6/2004
Authors: J A Olivier, L Liebenberg, Mark A Kedzierski, J P Meyer
Abstract: This paper presents a study of pressure drops during condensation inside a smooth, an 18 helical micro-fin, and a herringbone micro-fin tube. Measurements were conducted with refrigerant flowing through the inner tube (inner diameter of 8 to 9 mm) ...

49. Letter Report of a Life Cycle Cost Analysis for GSA Chillers
Published: 9/2/2004
Author: Mark A Kedzierski
Abstract: A life-cycle-cost analysis revealed that the combined GSA regions would save nearly half a billion dollars over 15 years in electricity costs with a hypothetical 30 % increase in chiller efficiency. The largest savings were apparent for GSA regions ...
