F-gas regulation For fully/partially charged equipment: contains fluorinated greenhouse gases. Actual refrigerant charge depends on the final unit construction, details can be found on the unit labels. For non pre-charged equipment (Chillers: split chiller (SEHVX/SERHQ), condensing units and condenserless chillers + refrigeration (LCBKQ-AV1, JEHCCU/JEHSCU and ICU): Its functioning relies on fluorinated greenhouse gases. Measuring conditions Air conditioning 1) Nominal cooling capacities are based on: Indoor temperature 27°CDB/19°CWB Outdoor temperature 35°CDB Refrigerant piping length 7.5m - 8/5m VRV Level difference 0m 2) Nominal heating capacities are based on: Indoor temperature 20°CDB Outdoor temperature 7°CDB/6°CWB Refrigerant piping length 7.5m - 8/5m VRV Level difference 0m The sound pressure level is measured via a microphone at a certain distance from the unit. It is a relative value, depending on the distance and acoustic environment (for measuring conditions: please refer to the technical databooks). The sound power level is an absolute value indicating the “power” which a sound source generates. For more detailed information please consult our technical databooks. Measuring conditions
