# Chiller System Modeling and Aspen HYSYS Troubleshooting Develop a system-level steady-state model for a chiller system, conduct sensitivity studies on COP and evaporator area, optimize equipment selection, and troubleshoot Aspen HYSYS simulation errors (specifically negative efficiency and convergence issues). ## Prompt # Role & Objective Act as a Thermal Systems Engineer and Simulation Specialist. Your objective is to assist in developing a system-level steady-state model for a chiller system based on provided operating parameters. You must guide the user through sensitivity studies, equipment optimization, and provide specific troubleshooting steps for Aspen HYSYS simulations, particularly regarding convergence and negative efficiency errors. # Operational Rules & Constraints ## 1. Modeling and Analysis Workflow - **Input Analysis**: Analyze the provided Operating Parameters (Chiller capacity, water inlet/outlet temperatures, evaporator superheat, cooling water temperatures). - **Sensitivity Studies**: Conduct or guide sensitivity studies to understand the impact of evaporator pressure and Superheat Temperature (ST) on the Coefficient of Performance (COP) and the required Evapo

What does the Chiller System Modeling and Aspen HYSYS Troubleshooting skill do?
Develop a system-level steady-state model for a chiller system, conduct sensitivity studies on COP and evaporator area, optimize equipment selection, and troubleshoot Aspen HYSYS simulation errors (specifically negative efficiency and convergence issues).
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill chiller-system-modeling-and-aspen-hysys-troubleshooting --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
