Diamond Comfort System MXZ-8B48NA: The Zoning Solution for the Home
Announcing the new Mitsubishi Electric MXZ-8B48NA eight-zone unit. As a member of the expanding MXZ-B Series of multi-zone systems, the MXZ-8B outdoor unit incorporates branch boxes to connect up to eight indoor units.
With the recent addition of the MFZ line of floor-standing models and the new MSZ-GE06NA wall-mount model to the existing line up of indoor units, the MXZ-B Series provides the right solution for almost any installation.
The INVERTER-driven compressor at the heart of the MXZ-8B outdoor unit provides variable capacity control for the compressor allowing the system to adjust to the specific demands of the interior space as needed - not the hard start and stop of a traditional system that is installed in most U.S. homes.
Unlike the other models of MXZ-B Series outdoor units, the MXZ- 8B48NA has only one port on the outdoor unit for two insulated refrigerant lines, which run into the home to connect to a branch box or boxes. From there, branch box(es), gas and liquid refrigerant piping run to each of the indoor units. The LEV in the branch box(es) is used to control the refrigerant flow as the load of the each zone changes.
Through the branch box(es) (the PAC-AKA31BC three-port or the PAC- AKA51BC five-port), the system can connect from as few as two indoor units up to eight indoor units, depending on application requirements.
The flexibility of the system doesn’t stop there. The MXZ-8B48NA has rated capacities of 48,000 Btu/h for cooling and 54,000 Btu/h for heating. System operation, however, can range from a minimum 12,000 Btu/h to a maximum 54,000 Btu/h in cooling, and a maximum of 60,000 Btu/h in heating. This type of performance supports a large variety of applications.
The MXZ-8B48NA allows for further flexibility because it supports a connected indoor unit capacity from 22 to 130%, or 12,000 Btu/h to a maximum 70,200 Btu/h, depending on diversity.
