Measurement Science Roadmap for Net-Zero Energy Buildings

March 18, 2010
Author(s)
Joan Pellegrino, Arthur H. Fanney, Andrew K. Persily, Piotr A. Domanski, William M. Healy, Steven T. Bushby
Buildings account for nearly a third of the world s energy use today, and this share is expected to rise along with population growth and levels of prosperity. In the United States, residential and commercial buildings consume about 40% of primary energy

Effect of Heat Pump Commissioning Faults on Annual Energy Use

January 24, 2010
Author(s)
Piotr A. Domanski, Hugh Henderson, William V. Payne
The study sought to develop an understanding of the impact of commissioning common faults the energy consumption of an air-to-air heat pump installed in a single-family house. Through annual simulations of the house/heat pump system, the study found that

CYCLE D Version 4.0: Theoretical Vapor Compression Cycle Design Program

June 23, 2009
Author(s)
J S. Brown, Piotr A. Domanski
This paper presents Version 4.0 of the CYCLE_D: NIST Vapor Compression Cycle Design Program. The model can simulate a basic subcritical or transcritical refrigeration cycle, both with or without a liquidline/ suction-line heat exchanger. In addition, the

CYCLE_D: NIST Vapor Compression Cycle Design Program Version 4.0 Users' Guide

June 23, 2009
Author(s)
J S. Brown, Piotr A. Domanski, Eric Lemmon
The CYCLE_D package simulates vapor compression refrigeration cycles that use pure refrigerants or mixtures of refrigerants. The model can simulate a basic subcritical or transcritical refrigeration cycle, both with or without a liquid-line/suction-line

This paper presents Version 4.0 of the CYCLE_D: NIST Vapor Compression Cycle Design Program. The model can simulate a basic subcritical or transcritical refrigeration cycle, both with or without a liquid-line/suction-line heat exchanger. In addition, 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

R-22 Replacement Status (in Russian)

June 25, 2008
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

Condensadores de Tubo con Aletas Optimizacion Mediante Sistema Inteligente

February 1, 2008
Author(s)
Piotr A. Domanski, David A. Yashar
The refrigerant circuitry influences a heat exchanger's attainable capacity. Typically, a design engineer specifies a circuitry and validates it using a simulation model or laboratory test. The circuitry optimization process can be improved by using

Application of an Evolution Program for Refirgerant Circuitry Optimization.

December 7, 2007
Author(s)
Piotr A. Domanski, David A. Yashar
Increased concerns about climate change have emphasized the importance of air-conditioning and refrigeration systems with a high coefficient of performance (COP). The effectiveness of heat exchangers significantly influences the vapor-compression system's

A Microfabricated Flow Controller for Refrigerant Expansion

October 1, 2007
Author(s)
David A. Yashar, Piotr A. Domanski, Don DeVoe
A flow controller for refrigerant expansion is reported. Devices are fabricated using a micromolding technique developed for thick nickel electroplating. The device consists of a short tube restrictor with an integrated normally-open valve which, when
