  1. Applied Systems Single Screw Chillers STEPLESS CAPACITY CONTROL

  2. Single Screw Chillers STEPLESS CAPACITY CONTROL What is new ? • Stepless Single Screw Compressor • One control platform, pCO² digital controller • PE - Condenser Coils • Max. Protection & Easy Installation • Nomenclature C O N T E N T New chiller ranges : • EWAP 110 ~ 540 MBYNN (EUWA - MZY) • EWAD 120 ~ 340 MBYNN (EUWA - KBXY) • ERAP 110 ~ 170 MBYNN (ER - MZY) • EWWD 120 ~ 540 MBYNN (EUW - MAXY) • EWLD 120 ~ 540 MBYNN (EUWL - MXY)

  3. Slide valve (New design) Gate rotor shaft (Strong type) New high efficiency motor New shape of the screw Stepless Single Screw Compressor History F-type G-type G-type stepless time 2000 2003 2005 Implications Increased COP 5% to 10%

  4. Stepless Single Screw Compressor History F-type G-type G-type stepless time 2000 2003 2005 Robustness, reliability = Robustness, reliability Performance = Performance Dimensions = Dimensions Limited control (stepped) ≠Extended control (stepless) The stepless compressor is a DAIKIN development ! Designed, tested and manufactured in Daikin’s own laboratories.

  5. Stepless Single Screw Compressor Launch of STEPLESS capacity control (Sales launch: August 2005) • Better control of the chiller at partial load • WHAT YOU WANT IS WHAT YOU GET • More accurate control of the temperature • OUTLET CONTROL (+/- 0,5°C) • If water quantity chiller + system ≥ minimum water quantity •  No buffertank required G-type stepless Higher Efficiency Saves the environment’s resources … and nevertheless your own resources DAIKIN compressor = the compressor that you can count on Designed, tested and manufactured in Daikin’s own laboratories.

  6. Stepless Single Screw Compressor Higher Efficiency STEPLESS capacity regulation The compressor has built-in capacity control by 15 – 100% by stepless slide valve mechanism, and adjustable volumetric ratio Chiller Load Chiller Load 100% 100% 30% Starting position Starting position 15% 12% 12% Demand Demand Double Circuit Single Circuit Designed, tested and manufactured in Daikin’s own laboratories.

  7. Stepless Single Screw Compressor STEPLESS capacity regulation How does it work ? Pilot Valve • Loading and unloading via Pilot Valve: • Pilot valve is driven by rod mechanism • The rod mechanism is driven by • shaded-pole motor • Loading • Unloading High pressure side Rod mechanism
