Modelling a Heat Pump with Linear Compressor using MATLAB Simulink

Click For Summary

Discussion Overview

The discussion revolves around modeling a heat pump with a linear compressor using MATLAB Simulink, specifically in the context of an electric vehicle. Participants are exploring the governing equations and formulas necessary for each component of the heat pump, as well as guidance on sizing the system.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant seeks assistance with the governing equations and sizing for a heat pump model in Simulink, expressing feelings of being out of depth.
  • Another participant requests information about the original poster's experience with Simulink and heat pump systems to better assist them.
  • The original poster shares their experience with MATLAB and Simulink, mentioning limitations due to budget constraints and a lack of physical heat pump access.
  • A suggestion is made to research existing solutions for cabin cooling and heating in electric vehicles, including service manuals and manufacturer documentation for linear refrigerant compressors.

Areas of Agreement / Disagreement

Participants have not reached a consensus, and multiple perspectives on how to approach the modeling task remain. There is no agreement on specific equations or methods yet.

Contextual Notes

The discussion highlights limitations related to the original poster's budget and access to physical models, which may affect the modeling process.

Who May Find This Useful

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.
