Different standards F-gas safety

Which standards regulate F-gas safety?

Two standards are applied to cover the safety regulations of refrigerants:

Flammability (1, 2L, 2, 3): covered by the specific heat pump standard IEC60335-2-40 (Ed. 6) as it prevails over EN378:2016
Toxicity (A or B): covered by the generic standard on refrigerants EN378:2016.

Limitations for flammability of A2L refrigerants are stricter than the ones for toxicity, so Shîrudo Technology focuses on offering maximum flexibility within the IEC60335-2-40 (Ed.6) requirements.

Peace of Mind

With Shîrudo Technology, Daikin ensures compliance to the product standard IEC60335-2-40 (Ed. 6) for indoor units. With factory-integrated refrigerant control measures, these systems are also the quickest and most flexible to design

There is no need for complex and time consuming calculations, even for small room applications.

How Shîrudo Technology works

Shîrudo Technology integrates refrigerant control measures from the factory, meaning the VRV 5 system is equipped with sensors, shut off valves, and an alarm, which are third party CB certificatied by a notified body (SGS CEBEC).

Integrated sensors to detect refrigerant leak

Integrated in every indoor unit
Self-monitoring, detects even the smallest refrigerant leak
Automatically activates refrigerant response measures: an alarm and shut off valves

Integrated alarm

Local visual and audible alarm integrated in Madoka wired remote control
An additional supervisor alarm can be integrated via:
- A field setting on the Madoka controller
- An input signal that triggers a 3rd party alarm
