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.
