VVR means Variable Volume Ratio. VVR is a technologies by Daikin. It permits the chiller’s compressor to adjust the compression ratio routinely when it senses the amount of elevate desired in almost any specified instant. It optimize the performance on the chiller and will save Strength.
MFD means Motorized Fireplace Damper. MFD is usually a sort of damper that is certainly each motorized and resistant to hearth. It employs an actuator to mechanically/remotely open and close.
