GAS-FUELED ENGINE-DRIVEN AIR CONDITIONING AND REFRIGERATION SYSTEMS FOR COMMERCIAL BUILDINGS Bruce B. Lindsay Project Manager commercial Space conditioning Gas Research Institute 8600 W. Bryn Mawr Avenue Chicago, IL 60631 Since 1985, the author has been involved in a program to develop a nominal 150 ton gas-fueled engine-driven water chiller for commercial buildings. The packaged system has bee...
We report the successful use of water-cooled radiofrequency where more traditional forms of neuroablation-conventional and pulsed radiofrequency-had failed to achieve adequate pain relief. We also discuss the mechanism of neural damage with water cooled radiofrequency and discuss why this technique may have a broader role in the management of a wide array of pain syndromes.
For Nonlinear Model Predictive Control (NMPC) to be implemented in real application, data driven models are advantageous since they can be easily constructed and are relatively fast, compared to first principle based models (simplified calculation [ISO 13790], dynamic simulation [EnergyPlus, ESP-r, TRNSYS, etc.], state space models, etc.). Gaussian Process Model (GPM), one of the data-driven ap...
Selecting the model is an important and essential step in model based fault detection and diagnosis (FDD). Factors that are considered in evaluating a model include accuracy, training data requirements, calibration effort, generality, and computational requirements. The objective of this study was to evaluate different modeling approaches for their applicability to model based FDD of vapor comp...
Modern concepts of nuclear reactors cooled with supercritical water are presented together with a short history. The supercritical water-cooled CANDU ((CANada Deuterium Uranium) is a registered trademark of AECL) reactor concept is fully discussed. Also, thermophysical properties at critical and supercritical pressures as well as heat transfer and hydraulic resistance at these conditions are pr...
The authors propose a solar cooling system employing a steam-driven triple effect absorption chiller as a new technique for saving CO2 emission in the air conditioning field. The absorption chiller is a cooling machine using thermal energy as a drive source, and it is ideal for utilizing solar heat. In addition, by employing a triple effect absorption chiller of high efficiency, a high energy s...
