Daikin develops remote monitoring and control system for chillers, integrating intelligent refrigerant leak detection

The company announces the launch of a new Refrigeration Leak Detection feature to assist chiller equipment and plant users with safety management and F-Gas compliance



The technology behind the new features is based on a unique new software algorithm developed by Daikin, innovation pioneer in this field, which uses historical data to signal an alarm in the event of a potential leakage and to report on the frequency of occurrences over time, allowing users to decide whether action is required to improve the efficiency and fiability of the HVAC-R system.

Avoiding refrigerant spills is extremely important and supports our efforts to achieve a net zero carbon footprint throughout the overall business by 2050. This new functionality integrated into Daikin’s remote product and facility monitoring services will help customers significantly reduce the environmental impact of refrigerant leakage. In addition, they can save time and money in the process of manually checking for leaks and avoid any surprises during the peak season. With this new tool our service team can intervene promptly, minimizing risks to customers, preserving valuable refrigerant and protecting the environment“, says Daniel Vasile, Managing Director of Daikin Romania.

The new algorithm detects even slow gas leakages over an extended load range, starting at 33 % of unit load compared to 50 % for other applications on the market, while referencing data from one month up to the 12 months previously.


Improved performance, reliability and more options


The new Refrigerant Leakage Detection service is now available as part of the Daikin on Site (DoS) cloud-based remote monitoring and control system. Setting new performance standards, the new Refrigerant Leak Detection service is distinguished by convenience and cost-effectiveness, as well as by the intelligent technology behind it.

Monitoring through the existing cloud removes the need for additional refrigerant leakage detection sensors and a local controller, helping to offset initial system purchase costs. The machine learning technology incorporated in the DoS cloud services enables improved detection rates of 15 % for leakages, surpassing current market performance. Faster leak identification and repair prevents the release of harmful refrigerants into the atmosphere, helping users to minimize their environmental impact.

The Refrigerant Leak Detection function can also be supplied bundled as part of a maintenance contract for users who choose to outsource monitoring and management services, where the service engineer receives an alarm at the time of leakage detection, analyses the situation remotely and on site, and quotes necessary repair measures as necessary.

Daikin plans to extend its refrigerant leak detection capabilities soon, with the introduction of a comprehensive refrigerant management service to assist Daikin users with F-Gas compliance through a one stop shop that includes the management of the amount of refrigerant and fulfilment of inspection requirements. The new Refrigerant Leak Detection Service is the latest in a series of advances, driven by a continuous product development program which is focused on innovation, performance and energy efficiency.


More information on how to add the new available refrigerant leak detection service to a Daikin remote monitoring, control and service subscription is available at Daikin România.
