PAC-LV11M-J — M-Controller for connecting residential indoor units of the DESIGN Inverter MSZ-EF22–50VE and STANDARD Inverter MSZ-SF15/20VA and MSZ-SF25–50VE series, as well as MFZ-KJ25/35VE floor-standing units.
PAC-PH01EHY-E — Electric heaters installed on the side panels (with control unit).
Description:
The only two-pipe heat recovery system. A BC Controller or WCB Controller is a mandatory component of the system.
Outdoor units with capacities of up to 63 kW feature a single-module design with one compressor. This simplifies installation and increases system reliability.
Outdoor units use exclusively inverter-driven compressors, eliminating high starting currents, extending compressor service life and improving overall system reliability.
The inverter-driven compressor achieves higher energy efficiency through a proprietary pulse-width modulation (PWM) algorithm with overmodulation. This method increases the inverter output voltage at high compressor motor speeds, improving efficiency.
Compressor heating in CITY MULTI G7 units (YNW Series) is provided by the motor stator windings. This ensures more efficient energy use compared with an external compressor crankcase band heater.
The control system dynamically adjusts (increases) the refrigerant evaporation temperature according to the air conditioning load to reduce power consumption in cooling mode. As the load decreases, the evaporation temperature increases, reducing compressor speed and improving motor efficiency.
The heat exchanger is manufactured using round copper tubes.
Seasonal and nominal energy efficiency have been improved through the use of a four-sided heat exchanger in the outdoor unit.
An integrated power module based on silicon carbide (SiC) technology has been introduced for the first time in the industry.
Fan power consumption has been reduced. The outlet guide vanes of the outdoor unit's axial fan enable higher static pressure at lower fan speeds and reduced power consumption.
The maximum height difference between outdoor and indoor units can be increased to 90 m when the outdoor unit is installed above the indoor units, and to 60 m when the outdoor unit is installed below them.
The total connected indoor unit capacity index can be increased to 200% by uploading special software to the outdoor unit.
Up to 50 indoor units can be connected to a single refrigerant circuit.
The outdoor unit features an insulated compressor compartment, significantly reducing noise levels in all directions.
PURY-P YNW-A-BS units with enhanced corrosion resistance are available on request.
Unit drawings in DXF format are available for free download in the Documentation section.
