Daikin improves reefer control software

Daikin improves reefer control software

There are now 42,000 Daikin units in operation fitted with the original DTMS software, which was introduced at the end of 2005 to reduce power consumption and improve carrying conditions for chilled cargoes. The DTMS control logic continually monitors both supply-air and return-air temperatures, together with their rate of change, and automatically adjusts the operation of the refrigeration unit based on these three parameters.

According to Daikin, this continual fine-tuning enables temperature and airflow inside the container to be controlled with much greater accuracy, as the system responds to real-time conditions. As a result, power consumption is reduced by up to 50% compared to a standard refrigeration unit.

The latest upgrade will provide further reductions in power consumption and can also be used in both chilled and frozen operations. From the second quarter of 2008, DTMS 2 will be available both for new and existing machines. Daikin says that the development of DTMS2 meets current industry demands for reduced energy consumption both for cost and environmental reasons, while maintaining accepted industry standards in cargo temperature control.
