Values are taken from PCVVN2507Aaprv, PDF page 203 (printed page 202). General Catalogue 2025; published on VRV.vn as Catalogue 2026 (EN).
Rated performance depends on test conditions and system combinations. Check the source notes when selecting equipment or comparing series.
Read original source notes (English)
Notes: Specifications are based on the following conditions;
• Cooling: Indoor temp.: 27°CDB, 19°CWB, Outdoor temp.: 35°CDB, Equivalent piping length: 7.5 m, Height difference: 0 m.
• Heating: Indoor temp.: 20°CDB, Outdoor temp.: 7°CDB, 6°CWB, Equivalent piping length: 7.5 m, Height difference: 0 m.
• Sound level: Anechoic chamber conversion value, measured at a point 1.5 m downward from the unit centre.
During actual operation, these values are normally somewhat higher as a result of ambient conditions.
*1: Power consumption values are based on conditions of rated external static pressure.
*2: External static pressure is changeable to set by the remote controller. These values indicate the lowest and highest possible static pressures.
The rated static pressure is 15 Pa.
