Numerical Investigation of Solar Vapor Absorption Refrigeration System Integrated with Phase Change Material for Industrial Application

Abstract

Most Industrial Processes In The World Need Refrigeration And Air Conditioning, To Create Cold Storage, Pasteurized Products, And A Comfortable Thermal Zone. But, The Conventional Refrigeration And Air Conditioning System Is One Of The Major Consumer Of Electrical Energy To Use It For Industrial Applications. Solar Energy Have A Comprehensive Applicability As An Energy Resource, Specifically For The Heat Requirement For The Vapor Absorption Refrigeration System, And It Is A Promising Technology To Create A Sustainable Absorption System. However, The Main Drawback Of This Resource Is The Intermittency And Unpredictability. The Objective Of This Study Is To Construct And Build Solar Vapor Absorption Refrigeration System Which Can Operate In Industrial Processing Units Without These Main Drawbacks. The System Comprised Of Three Main Subsystems: The Water Libr Absorption System, The Evacuated Heat Pipe Collector, And The Latent Heat Thermal Storage System. The Mathematical Modeling Based On Energy And Exergy Analysis, And Component Design Is Studied For The Absorption System. Furthermore, A Transient One-Dimensional Heat Transfer Model Is Developed For Both The Collector And The Storage Tank. For All Of The Three Subsystems, A General Python Code Program That Can Be Applied For Any Industrial Cooling Capacity Is Developed. Lastly, The Applicability Of The Model For Bekas Chemical Plc And Ah-Wan Food Complex Is Studied, With A Chiller Capacity Of 186.66 Kw And 245 Kw, Respectively. Each Components Of The Absorption System Is Designed For Both Industries. The Result Show That 242 Units Of Heat Pipe Evacuated Tube Collector With A Storage Tank Size Of 4.917m Height And 3.278m Diameter Is Demanded For Bekas Chemical Plc. On The Same Routine For Ah-Wan Food Complex, 310 Units Of Evacuated Tube Collector With A Storage Tank Size Of 5.334m Height And 3.556m Diameter Is Needed To Satisfy The Heat Demand With Supply.
