Influence of temperature sensors on temperature control of marine reefers.

Number: pap. n. 814

Author(s) : MARTÍNEZ S., FERRER M. A.

Summary

Temperature control in marine container application is very important, especially in chilled mode and for sensitive cargo like banana. Therefore, cargo owners specify tight temperature control requirements for the reefers. The paper analyzes the temperature control of a reefer working in different operating modes paying special attention to the differences in the temperature control depending how it is measured, mainly number and technology of the sensors used. The results also show the value that the cargo owner would see in the unit logs. The lack of a standard specifying the methodology to measure the temperature, as there are in other applications, increases the uncertainty when comparing test results among different laboratories. The results show that differences can be very large depending on the instrumentation used, affecting not only to the temperature control but also to the energy consumption and compressor cycles.
