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.
As much fresh air as possible should always be introduced into the cargo space throughout the voyage to maintain cargo quality.

It is used to cool down the cargo tanks before loading.
It is used to change the liquid cargo to vapour to heat the cargo if it is too cold.
In relation to exhaust gas measurement with a thermocouple, use of an amplifier which gives a mA-signal out is preferred. Why is this done?
This depends on the length of the compensation-cable.
The output signal from a thermocouple is at mV level,and can not be transferred over any long distance without loss of signal, giving a poor accuracy and poor noise immunity.
The signal out from the thermocouple is also mA, but have to be amplified in order to give a good signal to the alarm system.
