Overview

The VRF Control System Dashboard is an interactive monitoring and control platform for Variable Refrigerant Flow (VRF) systems. Built using Python Flask, it provides real-time data visualization and allows users to adjust system parameters such as water temperature and flow rate. The system communicates with APIs to fetch and update data dynamically. To optimize performance and reduce API request limits, a caching mechanism using PostgreSQL is implemented, ensuring a smooth user experience. The dashboard features a clean and intuitive UI, enabling seamless control over heating and cooling units.

Key Features

• Real-Time Monitoring: Displays live temperature, flow rate, and system status.
• API-Based Control: Users can adjust water temperature and flow rate through API interactions.
• Caching System: Optimized API requests using PostgreSQL-based caching to prevent excessive requests.
• System Flow Diagram: Provides a visual representation of the VRF system.
• Secure Authentication: Ensures controlled access to system settings.

Technologies Used

• Python & Flask: Backend framework for API management and system logic.
• PostgreSQL: Database for storing parameters and implementing short-term caching.
• HTML, CSS, JavaScript: Frontend for building an interactive UI.
• REST APIs: Used for fetching and updating VRF system parameters.
• IoT Integration: Connects with VRF hardware for real-time data exchange.
