Reduced Order Modeling of Heat Exchangers Using High Order Finite Control Volume Models
A distributed parameter approach for dynamic modeling of heat exchangers and using it to obtain low order models have been presented in this report. The finite control volume (FCV) approach accurately captures the distributed ...
Forced Dispersion of Liquefied Natural Gas Vapor Clouds with Water Spray Curtain Application
There has been, and will continue to be, tremendous growth in the use and distribution of liquefied natural gas (LNG). As LNG poses the hazard of flammable vapor cloud formation from a release, which may result in a massive ...
The Persistence of Savings Obtained from Commissioning of Existing Buildings
The objective of this study is to investigate the reasons why the performance of mechanical systems degrades over time after commissioning and to recommend intervals at which testing should be performed to maintain the ...
Modeling the Effects of Refrigerant Charging on Air Conditioner Performance Characteristics For Three Expansion Devices
An experimental and analytical study concerned with the off-design refrigerant charging of air conditioners is presented. A series of experiments were conducted to characterize the effects of refrigerant charge and type ...
Two-Phase Flow of HCFC-22 and HFC-134a through Short Tube Orifices
HCFC-22 and HFC-134a were used with short tube orifices having length to diameter ratios ranging from 5 to 20 in a 9.53 mm (3/8 in.) refrigerant line to investigate both two-phase and subcooled liquid flow entering the ...
A Methodology to Measure Retrofit Energy Savings in Commercial Buildings
Measured energy savings promote and sustain energy conservation retrofits by verifying the success of retrofits, determining pay-back schedules, guiding the selection of future retrofits and identifying opportunities for ...
Study of Air Infiltration Energy Consumption
The influence of heat recovery on the energy impact of air infiltration, and the systematic error due to the steady-state method were studied both experimentally and theoretically. Two methodologies suitable for measurement ...
