Most fruit cargoes carried under refrigeration require 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. Shipper's instructions will often indicate 'constant air change' as a requirement for a cargo. Why, even though this is a crude method for controlling the cargo space atmosphere, is this type of instruction given?
Some cargoes are very sensitive to ethylene levels and it may be difficult to accurately measure the low levels that would affect a cargo.
It is the standard method and it is always done that way for simplicity.
Fresh air helps to acclimatise the cargo to the prevailing ambient conditions.
