Heating Mode Performance Measurements For A Residential Heat Pump With Single-Faults Imposed

September 30, 2009

Author(s)

William V. Payne, Piotr A. Domanski, Seok H. Yoon

The objective of this research was to acquire heating mode experimental data for a residential heat pump needed for the development of a FDD methodology. Within this project, a heat pump equipped with a thermostatic expansion valve (TXV) was tested in the

Cooling Mode Fault Detection And Diagnosis Method For A Residential Heat Pump

October 17, 2008

Author(s)

Minsung Kim, Seok H. Yoon, William V. Payne, Piotr A. Domanski

Performance characteristics of a R410A residential unitary split heat pump equipped with a thermostatic expansion valve (TXV) were investigated in the cooling mode under no-fault and faulty conditions. An automated method of steady-state detection was

Design of a steady-state detector for fault detection and diagnosis of a residential air conditioner

May 1, 2008

Author(s)

Minsung Kim, Seok H. Yoon, Piotr A. Domanski, William V. Payne

This paper presents a general methodology for developing a steady-state detector for a vapor compression system based on a moving window and using standard deviations of seven measurements selected as features. The feature thresholds and optimized moving

Longitudinal Heat Conduction in Finned-Tube Evaporators

August 21, 2007

Author(s)

Piotr A. Domanski, William V. Payne, J M. Choi

The paper evaluates performance of finned-tube evaporators at different refrigerant exit superheats to assess the impact of longitudinal heat conduction on capacity.

A Low Cost Digital Vibration Meter

April 1, 2007

Author(s)

William V. Payne, Jon Geist

This report describes the development of a low cost vibration amplitude sensor. The processes used to develop this sensor involve the use of Micro-Electronic and Mechanical Systems (MEMS) manufacturing techniques. The major mechanical element of the

Survey of HSPF and Heating Capacity Ratings for ICM Mixed Systems Relative to OEM Mixed Systems and Highest Sales Volume Tested Combinations

April 1, 2007

Author(s)

William V. Payne

This investigation compares the Heating Seasonal Performance Factor (HSPF) and the high temperature heating capacity (Q(47)) ratings of Independent Coil Manufacturers (ICMs) and Original Equipment Manufacturers (OEMs) to determine the distribution of mixed

Performance of a Residential Heat Pump Operating in the Cooling Mode With Single Faults Imposed

September 1, 2006

Author(s)

William V. Payne, Piotr A. Domanski, Minsung Kim, Christian Hermes

System behavior of a R410A residential unitary split heat pump system operating in the cooling mode was investigated. Seven artificial faults were implemented: compressor/reversing valve leakage, improper outdoor air flow, improper indoor air flow, liquid

Performance of a Residential Heat Pump Operating in the Cooling Mode with Single Faults Imposed (NISTIR 7350)

September 1, 2006

Author(s)

Minsung Kim, William V. Payne, Piotr A. Domanski, Christian Hermes

System behavior of a R410A residential unitary split heat pump system was investigated. The system was operated in cooling mode and used a thermostatic expansion valve (TXV) as the refrigerant expansion device. Seven artificial faults were tested

Survey of SEER Ratings for Independent Coil Manufacturer Mixed Systems Relative to Original Equipment Manufacturer Mixed Systems and Highest Sales Volume Tested Combinations

September 1, 2006

Author(s)

William V. Payne

This investigation compares the Seasonal Energy Efficiency Ratio (SEER) ratings of independent coil manufacturers (ICMs) and original equipment manufacturers (OEMs) to determine the distribution of mixed system SEER ratings provided by ICMs and OEMs. ICMs

Linear-Fit-Based Rating Procedure for Mixed Air-Source Unitary Air Conditioners and Heat Pumps Operating in the Cooling Mode

June 1, 2006

Author(s)

William V. Payne, Piotr A. Domanski

The purpose of this report is to establish the method for determining the cooling performance ratings of air-source unitary split-system air conditioners and heat pumps consisting of an outdoor section and an indoor section that were not tested together as

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
