Monitor Refrigerant in VRF Systems

ASHRAE Standard 15: This one’s all about safety. It sets limits on refrigerant charges to prevent disasters. It now nods to VRF systems, emphasizing the need for refrigerant detection. So, if the VRF system got a leak, the sensor should detect the leak at early detection and prevention.
IEC 60335-2-40 standard deals with the safety of electric heat pumps, sanitary hot water heat pumps and air conditioners, incorporating motor-compressors as well as hydronic fan coils units, dehumidifiers (with or without motor-compressors), thermoelectric heat pumps and partial units. Annex LL specifically defines requirements for refrigerant detection systems for use in such appliances, as well as testing methods to ensure the requirements are met.
