Hypothesis

The study aims to develop a low-cost, portable gas-sampling system for measuring air infiltration in refrigerated areas.

Conclusion

The developed gas-sampling system effectively measures air infiltration with minimal loss of accuracy.

Supporting Evidence

  • The sampler can detect sulphur hexafluoride at very low concentrations, making it suitable for large rooms.
  • The device is designed to be portable and low-cost, addressing the limitations of existing equipment.
  • The system can be modified for different sizes of test tubes or to sample liquids.

Takeaway

This study created a small and affordable device that can take air samples to check for leaks in cold storage rooms.

Methodology

The system uses a rotating drum with vacuum-sealed test tubes to sample gas and measures the concentration of a tracer gas over time.

Limitations

The size of the equipment limits the volume of sampled gas, which may affect accuracy in some applications.
