This is an HVAC Refrigeration System Schematic Template. It illustrates the components and fluid flow of a heating, ventilation, and air conditioning refrigeration system, including an air handler, compressor, heat exchangers, valves, and measurement points for temperature, pressure, and airflow. Ideal for HVAC engineers, system designers, or maintenance technicians, this template helps visualize and analyze the refrigeration cycle, component interactions, and performance metrics to support system design, troubleshooting, and optimization.
