33. Effects of Non-Uniform Air Flow on Finned-Tube Evaporator Performance
Published: 8/1/2003
Authors: John Choi, William V Payne, Piotr A Domanski
Abstract: An experimental investigation was implemented to determine the capacity degradation due to non-uniform refrigerant and air flow distributions, and to assess the potential to recover the lost capacity via controlling refrigerant distribution between i ...

34. Potential Benefits of Smart Refrigerant Distributors
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6946
Published: 1/1/2003
Authors: William V Payne, Piotr A Domanski
Abstract: The main goal of this study was to investigate the benefits possible for finned tube refrigerant evaporators when refrigerant distribution was precisely controlled to produce a desired equal superheat in each circuit. This goal was accomplished by e ...

35. Properties and Cycle Performance of Refrigerant Blends Operating Near and Above the Refrigerant Critical Point
Published: 9/1/2002
Authors: Piotr A Domanski, William V Payne
Abstract: Performance of R22 and R410A split air conditioners was evaluated experimentally at the ambient temperature range from 82 F to 135 F. Capacity and EER decreased as the outdoor temperature increased. The capacity of the R410A system relative to th ...

36. Comparison of an R22 and an R410A Air Conditioner Operating at High Ambient Temperatures.
Published: 7/16/2002
Authors: William V Payne, Piotr A Domanski

37. A Comparison of an R22 and an R410A Air Conditioner Operating at High Ambient Temperatures
Published: 7/1/2002
Authors: William V Payne, Piotr A Domanski
Abstract: R22 and R410A split air-conditioning systems were tested and compared as outdoor temperature ranged form 27.8 C (82.0 F) to 54.4 F (130 F). The R410A system tests were extended t 68.3 C (155.0 F) ambient temperature with a customized compresso ...

38. Refrigerant Flow Through Flexible Short-Tube Orifices
Series: OTHER
Published: 4/1/2002
Authors: William V Payne, Y C Kim, Dennis L O'Neal, Mohsen Farzad
Abstract: 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 wit ...

39. Refrigerant Flow Through Flexible Short-Tube Orifices
Published: 4/1/2002
Authors: Y Kim, D L O'Neal, William V Payne, MD L Farzad
Abstract: A series of tests for a R-22/lubricant mixture (1.2 % oil concentration) were performed with two flexible short tube orifices to develop flow data over a range of typical air conditioner operating conditions. One orifice had a modulus of elasticity ...
