Refrigerant leak detection added to Daikin monitoring system

UK: Daikin Applied has added a refrigerant leak detection function to its Daikin on Site cloud-based remote monitoring and control system.

The new smart feature is designed to assist chiller equipment and plant users with safety management and F-Gas compliance. 

Daikin On Site can provide 24/7 real time data, all year round, tracking chiller plant operations and their correct functionality. 

The new leak detection capabilities are based on a new Daikin-developed software algorithm. It uses historical data to activate an alarm in the event of a potential leakage and to report on occurrences and frequency over time, allowing users to have a complete overview of the events occurred over up 12 months, and then, allowing users to take action and set preventive measures if needed.

The new algorithm is said to be able to detect even slow gas leakages over an extended load range, starting at 33% of unit load.

The Refrigerant Leak Detection function within Daikin on Site can be bundled as part of a maintenance contract for users who choose to outsource monitoring and management services. 

The service engineer will receive an alarm at the time of leakage detection, so will be able to assess the situation, either remotely or on site, and identify the necessary repair measures for the specific case.

Daikin insists that monitoring through the existing cloud platform removes the need for additional refrigerant leakage detection sensors and local controllers, helping to offset initial system purchase costs. The machine learning technology enables improved detection rates by 15% for leakages, says Daikin.
