Example: cooling
Same refrigerant temperature
(Rt) throughout the season
Refrigerant T
Currently on all VRF systems
Fixed Rt
As outdoor temperature falls, the
capacity of the system is adjusted by
reducing the speed of inverter
compressors
Capacity & Load
Reducing compressor speed improves
efficiency, but only to a certain extent:
at very low compressor speeds,
compressor efficiency actually falls

Efficiency Benefit
Compressor
efficiency
With a higher refrigerant temperature, the compression ratio falls so the
compressor doesn’t have to work so hard.
This prevents it from operating at it a less efficient low operating speeds.

DZK ─ This is how it works
The Zoning Box, that contains
motorized dampers and controls,
mounts on the Daikin VRV
indoor unit fan coil and integrates
seamless with the VRV controls
The Motorized Dampers in the
Zoning Box controls the air flow
to each zone automatically
The Main Thermostat and the
Wireless Thermostats in each
zone allows the user to set the
desired temperature, schedule,
etc.
