Test wind effects with surface and internal readings

Wind can increase heat exchange between a surface and its surroundings; the direction depends on conditions. Separate surface and product readings.

Short answer

Wind does not always cool a carrier. Depending on temperature conditions between the surface, ambient air and solar exposure, it can speed heat transfer; product temperature responds differently because of insulation and load. Measure and compare surface, air and product zones separately on the same route.

Wind affects convective heat exchange at a surface; heat-flow direction depends on surface and ambient conditions. This does not mean the product cools at the same rate.

Record conditions together. Along the route, note ambient air, surface temperature, sun or shade and wind exposure. Keep the surface measurement separate from the product-zone sensor.

Compare transport arrangements. Test exposed and sheltered transport only with the same load, starting condition and route. Keep sensor location and lid openings consistent.

Match the trace to the load

Compare timestamped product readings with stops and waiting records. A change coinciding with wind alone does not prove cause and effect.

Decide for the product

Verify product acceptance conditions in its documentation or procedure. If the test conditions do not cover another route or load, do not generalise the result.
