Why shippers instructions often indicate constant air change as a requirement for a refrigerated cargo?

Most fruit cargoes carried under refrigeration require the introduction of fresh air into the cargo space to remove any excess carbon dioxide and ethylene produced by respiration of the cargo and sensors are fitted to detect these gases. Some cargoes are very sensitive to ethylene levels and it may be difficult to accurately measure the low levels that would affect a cargo.
