Data Analysis and Modeling of Chilled Water Loops in Air Conditioning Systems

Modeling and Generalized Predictive Control for Chilled Water in Central Air-conditioning System

In this paper, the overall framework for chilled water system in heating, ventilation, and air-conditioning (HVAC) system was analyzed, then aiming at the chilled water system, the control loop in secondary pump frequency pressure difference was identified and the Generalized Prediction Control (GPC) algorithm was designed and deployed for the strategy of fixed pressure difference control. The ...

Comparison of energy performance and economics of chilled water thermal storage and conventional air-conditioning systems

During the summer of previous years, Kuwait faced a series of power shortages emphasizing the need for urgent commissioning of power generation projects. It is estimated that the demand for electricity is growing at an average of 5.4% per year, encouraged by government subsidies and driven by the rapid and continual expansion in building construction, urban development, and heavy reliance on ai...

Thermodynamics of Air/Water-Cycle Air-Conditioning Systems

Passive Energy Air-to-Water Heat Pipe Based Heat Exchanger and its Potential of Air Pre-cooling in Air Conditioning Systems for Iran Climate

Air pre-cooling equipment is normally being employed in air-conditioning systems for pre-cooling the ambient outdoor air to enhance the air-conditioning systems performance. In this study, the potential of a passive water-to-air heat pipe based heat exchanger (HPHEX) for air pre-cooling purpose in air-conditioning systems for the high cooling load demanding regions of Iran was investigated. To ...
