Modelling a Heat Pump with Linear Compressor using MATLAB Simulink

Click For Summary
SUMMARY

The discussion focuses on modeling a heat pump with a linear compressor using MATLAB Simulink, specifically for an electric vehicle application. The user, a final year mechanical engineering student, seeks assistance with the governing equations and sizing of the heat pump components. They have three years of experience with MATLAB and basic familiarity with Simulink, but lack access to physical heat pumps due to budget constraints. Recommendations include researching service manuals of electric vehicles and documentation from linear refrigerant compressor manufacturers.

PREREQUISITES
  • Familiarity with MATLAB and Simulink (version unspecified)
  • Understanding of heat pump thermodynamics
  • Knowledge of linear compressor operation
  • Basic principles of modeling and simulation
NEXT STEPS
  • Research governing equations for heat pump components
  • Explore sizing techniques for heat pumps in electric vehicles
  • Investigate service manuals of commercially available electric cars
  • Review documentation from manufacturers of linear refrigerant compressors
USEFUL FOR

This discussion is beneficial for mechanical engineering students, automotive engineers, and anyone involved in the design and modeling of thermal systems for electric vehicles.

Hello, I am a final year mechanical engineering student designing a heat pump with a linear compressor for an electric vehicle and have decided to model this using Simulink, I would love some help on the governing equations/formulas needed for each component of the heat pump as well as guidance in terms of sizing of the heat pump, I feel a little out of my depth and would appreciate any help, Thanks! :)

Welcome to PF.

Please tell us what you know so far. What is your experience with Simulink? What kind of heat pump systems do you have experience with?
 
Been using MATLAB for 3ish years and only really just started with Simulink but can now model functions and subsystems, meaning I can setup equations of second order differentiations etc. The university has a small £150 budget so I am not able to use any physical heat pump and only know what I have read from numerous google scholar articles. My dissertation supervisor is a bit useless so I am on my own for this one!

Have you researched actual solutions for cabin cooling and heating used in commercially available electric cars?
Perhaps service manuals of e-cars are a good starting point, as well as available documentation from manufacturers of linear refrigerant compressors.
