This course will provide the student with an understanding of how to model closed-loop, multi-phase systems using EASY5. Applications include HVAC, environmental controls, and refrigeration. The governing physical principles and the corresponding equations of state will be presented as well as a detailed example model.
Pre-requisites:
EAS101 (Introduction to Dynamic System Modeling and Simulation using Easy5) or equivalent experience.
Topics:
- Overview of the Multiphase (VC) library
- Governing dynamic equations
- Phase and phase change modeling
- Orifice flow
- Using published fluid data tables
Workshops include:
1. Refrigerant line
2. Adding a compressor
3. Modeling a condenser and expansion valve
4. Adding an evaporator
5. Closing the refrigerant loop
6. Adding EEV control
7. Heat exchange to the environment
8. Calculating COP and a stable closed-loop operating point
9. Thermostatic control and realistic environmental conditions
10. Generating custom fluid properties for the Multiphase library
