How to Download and Use ABSIM: A Free Software for Absorption Heat Pump and Liquid Desiccant Systems Simulation
ABSIM is a software developed by Oak Ridge National Laboratory (ORNL) that can simulate various absorption heat pump and liquid desiccant systems using different cycle configurations and working fluids. ABSIM can calculate the operating parameters, predict the performance, and compare different systems on a uniform basis. ABSIM is a very useful and accurate tool for researchers and engineers who want to investigate and optimize absorption systems for various applications.
In this article, we will show you how to download and use ABSIM for free. You will need a Windows computer with at least 4 GB of RAM and 100 MB of free disk space. You will also need an internet connection to download the software and access the online documentation.
Step 1: Download ABSIM
To download ABSIM, you need to visit the ORNL website at https://www.ornl.gov/publication/development-updated-absorption-simulation-software-absim and click on the \"Download\" button. You will be asked to fill out a short form with your name, email address, affiliation, and purpose of use. After submitting the form, you will receive an email with a link to download the software as a zip file.

Step 2: Extract ABSIM
After downloading the zip file, you need to extract it to a folder of your choice. You can use any software that can handle zip files, such as WinZip or 7-Zip. To extract the file, right-click on it and select \"Extract All\" or \"Extract Here\". You will see a folder named \"ABSIM\" that contains the executable file (ABSIM.exe) and other files and folders.
Step 3: Run ABSIM
To run ABSIM, you need to double-click on the executable file (ABSIM.exe). You will see a window that shows the main menu of the software. From here, you can select different options to create, edit, run, and analyze absorption systems. You can also access the online documentation by clicking on the \"Help\" button.
Step 4: Create or Load an Absorption System
To create or load an absorption system, you need to click on the \"File\" button and select \"New\" or \"Open\". If you select \"New\", you will be asked to choose a system type (heat pump or liquid desiccant), a cycle configuration (single-effect, double-effect, etc.), and a working fluid pair (water-lithium bromide, ammonia-water, etc.). You will then see a window that shows the schematic diagram of the system and the input parameters for each component. You can modify the input parameters by clicking on the component name and entering new values in the corresponding fields.
If you select \"Open\", you will be asked to browse for an existing ABSIM file (.abs) that contains a saved absorption system. You can use any of the example files that are included in the ABSIM folder or any file that you have created or received from others. You will then see a window that shows the schematic diagram of the system and the input parameters for each component. You can modify the input parameters by clicking on the component name and entering new values in the corresponding fields.
Step 5: Run an Absorption System
To run an absorption system, you need to click on the \"Run\" button and select \"Run\". You will see a window that shows the progress of the simulation and any error messages if there are any. The simulation may take from a few seconds to several minutes depending on the complexity of the system and your computer speed. When the simulation is finished, you will see a message that says \"Simulation Completed Successfully\".
Step 6: Analyze an Absorption System
To analyze an absorption system, you need to click on the \"Results\" button and select one of the options: \"Summary\", \"Detailed\", \"Graphs 29c81ba772
