Getting Constant Cooling: Examining Heat Leakage

Click For Summary
SUMMARY

This discussion focuses on modeling temperature changes in a thermally insulated object subjected to constant cooling power while accounting for heat leakage. The user seeks to understand if applying constant heating and then reversing the results would yield accurate insights into heat leakage. The consensus indicates that this method, despite potential confounding factors, is likely to provide satisfactory results for estimating heat loss.

PREREQUISITES
  • Understanding of thermodynamics principles, particularly heat transfer.
  • Familiarity with thermal insulation concepts and their impact on temperature changes.
  • Basic knowledge of experimental design and data analysis techniques.
  • Experience with plotting temperature data over time using tools like Python's Matplotlib.
NEXT STEPS
  • Research methods for calculating heat transfer coefficients in thermally insulated systems.
  • Explore the use of thermal imaging to measure heat leakage in real-time.
  • Learn about the principles of thermal equilibrium and transient heat conduction.
  • Investigate data analysis techniques for interpreting temperature change data effectively.
USEFUL FOR

Thermal engineers, physicists, and researchers involved in heat transfer analysis, as well as anyone interested in optimizing thermal insulation and cooling systems.

I have an object that is decently thermally insulated. I want to plot how a constant cooling power of a few watts for a few minutes is going to affect the object's temperature. I need to account for how much heat is leaking in.

Getting a constant cooling doesn't seem easy. If I instead use constant heating and then just "flip" the results, would my results be good? I.e would I see how much heat is leaking in by looking at how much is leaking out?

There are a number of potential confounding factors, but odds are, what you suggest will be good enough.
