Numerical analysis of annual exergy consumption for daylighting, electric-ligthing, and space heating/cooling system | 1999 | English
The purpose of this study is to show explicitly a series of exergy input, output, and consumption for daylighting, electric-lighting, and space heating/cooling system and hence to reveal how daylighting system consumes solar exergy and how electri
RARX algorithm based model development and application to real time data for on-line fault detection in Vav Ahu Units | 1999 | English
Assimilation of cost-effective Fault Detection and Diagnosis (FDD) technique in building management sys- tem can save enormous amount of energy and material.
When some faults take place in a thermal storage HVAC system, changing pattern of the temperature profiles of the thermal storage tank is useful to infer where some faults exist.
Internal melt ice-on-coil tank with built-in horizontal tubes is a kind of ice tank used widely. Its discharge process is effected greatly by density different between ice and water.
A reduction in the emissions arising from urban activities demands a combination of energy efficiency measures and a move away from fossil fuel sources.
The purpose of this study is to develop the technique that mixing energy loss is predicted at the time of the air conditioning system design by the simulation.
In the present work, human thermal comfort is investigated within the built environment. The analysis is based on two building thermal simulation models.
The paper discusses the development of a computational thermal simulation engine as an object. The simulation engine utilizes Transfer Function (TF) Algorithms where all TF procedures have been implemented.
