Daikin’s Navigator maps efficiency route
10th May 2017
USA: Daikin Applied has launched the Navigator, a screw compressor water-cooled chiller using Variable Volume Ratio (VVR) technology.
Navigator’s single VFD-driven screw compressor is said to bring new levels of performance to applications that aren’t suited to traditional centrifugal chillers or magnetic bearing solutions. Efficiencies are said to meet or exceed ASHRAE 90.1-2016 levels with IPLVs as low as 0.36kW/ton.
Daikin Applied’s VVR compression technology is said to sense the precise amount of lift needed and adjusts the compression ratio on the fly to deliver optimal efficiency, regardless of ambient temperature or time of day.
With Daikin’s Navigator RapidRestore cooling can be restored in as little as 35 seconds. A power loss could turn into a critical loss of cooling in mission critical facilities such as data centres, health care buildings, or manufacturing processes. In addition, the fast-loading option can restore full load cooling capacity in under 160 seconds.
The Navigator is designed for use with R34a and covers capacities from 527 to 1055 kW.
