An Improved Two-Phase Pressure Drop Correlation for 180 degrees Return Bends

May 1, 2006
Author(s)
Piotr A. Domanski, Christian Hermes
A new correlation for two-phase flow pressure drop in 180? return bends is proposed based on a total of 241 experimental data points for R-22 and R-410A. The data span smooth tubes with inner diameters (D) from 3.25 mm to 11.63 mm, bend radiuses (R) from 6

R-22 Replacement Status (in Italian)

February 1, 2006
Author(s)
J M. Calm, Piotr A. Domanski
Since its initial recognition in 1928 and commercialization in 1936, R-22 has been applied in systems ranging from the smallest window air conditioners to the largest chillers and heat pumps, including those for district cooling and heating. Individual

Mass Flow Rate of R-410A Through Short Tubes Working Near the Critical Point

June 1, 2005
Author(s)
Y Kim, William V. Payne, John Choi, Piotr A. Domanski
Experimental data were taken to examine R-410A mass flow rate characteristics through short tube restrictors at upstream pressures approaching the critical point. Four short tube restrictors were tested by varying upstream pressure from 2619 kPa to 4551

A Curve-Based Mixed System Rating Method

May 5, 2005
Author(s)
Piotr A. Domanski, William V. Payne
The curve-based method was evaluated based on performance predictions for nine mixed systems, which were also tested by an independent testing laboratory. Capacity predictions were within 5% of the tested values for six of nine mixed systems, and four of
