The Refrigeration Training System is designed to work with the LVHVAC software, which enables real-time monitoring of temperature and pressure at key points in the system. The software automatically calculates and updates system variables, such as refrigeration capacity, coefficient of performance, and superheat. It also displays a real-time pressure-enthalpy diagram that changes as the refrigeration cycle progresses. Additionally, a trend recorder generates a graph over time of the acquired data on pressure, temperature, and compressor.
