Monitoring Techniques for the Net-Zero Energy Residential Test Facility

December 31, 2014
Author(s)
Mark W. Davis, William M. Healy, Matthew Boyd, Lisa Ng, William V. Payne, Harrison Skye, Tania Ullah
NIST has constructed a Net-Zero Energy Residential Test Facility that will be used as a testbed for investigating the measurement science related to systems, components, and operations that will lead to homes that generate as much energy over a course of a

Sensitivity Analysis of Installation Faults on Heat Pump Performance

October 8, 2014
Author(s)
Piotr A. Domanski, Hugh Henderson, William V. Payne
Numerous studies and surveys indicated that typically-installed HVAC equipment operates inefficiently and wastes considerable energy due to different installation errors (faults), e.g., improper refrigerant charge, incorrect airflow, oversized equipment

Residential Heat Pump Heating Performance with Single Faults Imposed

October 29, 2010
Author(s)
William V. Payne, Piotr A. Domanski, Seok Ho Yoon
A heat pump equipped with a thermostatic expansion valve (TXV) was tested in environmental chambers during steady-state no-fault and imposed-fault operation. The studied system was an R410A split residential heat pump with an 8.8 kW nominal cooling

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
