Refrigerant Flow Through Flexible Short-Tube Orifices

April 1, 2002

Author(s)

William V. Payne, Y C. Kim, Dennis L. O'Neal, Mohsen Farzad

Flexible short-tube orifices were designed to decrease their diameter as the pressure differential across them increases under high outdoor temperatures. A series of tests for an R-22/lubricant mixture (mass fraction of oil 1.2%) were performed with two

A Comparison of Rating Water-Source Heat Pumps Using ARI Standard 320 and ISO Standard 13256-1

September 1, 2001

Author(s)

William V. Payne, Piotr A. Domanski

This investigation compares the ARI 320 (1998) and the ISO 13256-1 (1998) heating and cooling standards for water-source heat pumps to determine the difference in capacity and efficiency for a given heat pump tested with these standards. Multiple tests

A Water-to-Water Heat Pump Using Hydrocarbon and Hydrofluorocarbon Zeotropic Mixtures With and Without an Internal Heat Exchanger

January 1, 2000

Author(s)

William V. Payne, Piotr A. Domanski, E A. Silk

This investigation overviews the comprehensive results of the experimental study pertaining to flammable refrigerant alternatives in water-to-water heat pumps for building and home applications. In contrast to the comprehensive fluid survey of the initial

A Study of a Water-To-Water Heat Pump Using Hydrocarbon and Hydrofluorocarbon Zeotropic Mixtures

May 1, 1999

Author(s)

William V. Payne, Piotr A. Domanski, J Muller

This investigation compared the performance of R22 to the performance of propane (R290) and zeotropic mixtures of HFC's and hydrocarbons in a water-to-water heat pump. Baseline testing began with R22 and proceeded to R290, R32/290, R32/152a, and R290/600a

A Study of a Water-to-Water Heat Pump Using Flammable Refrigerants

June 1, 1998

Author(s)

William V. Payne, Piotr A. Domanski, J Muller

This investigation compared the performance of R22 to the performance of R290 and that of flammable zeotropic mixtures, R32/290 and R32/152a. The tests were conducted in a test apparatus specially designed to simulate a residential water-to-water heat pump
