The smart Trick of hvac system meaning That Nobody is Discussing

VVR means Variable Volume Ratio. VVR is usually a engineering by Daikin. It enables the chiller’s compressor to regulate the compression ratio automatically when it senses the level of carry needed in any offered second. It enhance the performance in the chiller and will save Power.

BDD means Backdraft Damper. BDD is employed to make certain air flows in one route. It prohibit air from flowing in the reverse path by using a system to routinely close the damper once the air is flowing in the incorrect way.
